extensible storage engine ( ese ) , also known as jet blue , is an isam ( indexed sequential access method ) data storage technology from microsoft .

ese is the core of microsoft exchange server , active directory , branch cache , and windows search .

it 's also used by a number of windows components including windows update client and help and support center .

its purpose is to allow applications to store and retrieve data via indexed and sequential access .

ese provides transacted data update and retrieval .

a crash recovery mechanism is provided so that data consistency is maintained even in the event of a system crash .

transactions in ese are highly concurrent making ese suitable for server applications .

ese caches data intelligently to ensure high performance access to data .

in addition , ese is lightweight making it suitable for auxiliary applications .

the ese runtime ( esent.dll ) has shipped in every windows release since windows 2000 , with native x64 version of the ese runtime shipping with x64 versions of windows xp and windows server 2003 .

microsoft exchange , up to exchange 2003 shipped with only the 32-bit edition , as it was the only supported platform .

with exchange 2007 , it ships with the 64-bit edition .

the extensible storage engine is an advanced and sequential method to use the stored and retrieved data from tables . it supports few schemas that includes wide tables with many sparse and multi - valued columns , as well as sparse and rich indexes . while accessing the data , it enables to store the data for maximize the performance . the edb server allows to access the data from ese ( extensible storage engine ) and to store the database in hierarchical storage format that includes messages , folders and attachments , etc . these files stores the rich data ( smtp , mapi and https messages ) in each table and its properties varies . in addition , . edb file extension is accessed directly by ese .
these files belong together and create a so - called “storage group” . during the installation of exchange server one database is created in a storage group . in exchange 2007 the public folder database is created in a second storage group . when replication technology ( like lcr , ccr or scr ) in exchange 2007 is used than only one database per storage group can exist . if no replication technology is used , up to five databases can be created in each storage group .
cql2 was easy to implement since it maps so straightforwardly to what the storage engine has been doing all along . but it turns out there are several major problems with this approach :
extensible storage engine ( esent ) , also known as jet api , is an indexed sequential access method ( isam ) data storage technology from microsoft . the esent runtime has been a part of windows since windows 2000 and has been used in products like microsoft exchange , active directory , windows update , and desktop search . this application stores and retrieves data from tables using indexed or sequential cursor navigation .
alternate storage is completely transparent at the imap / pop level . users accessing mail through imap or pop cannot normally tell if any given message is stored in primary storage or alternate storage . conceivably users might be able to measure a performance difference ; the point is that there is no imap / pop command which could be used to expose this information . it is entirely possible to have a mail folder which contains a mix of messages stored in primary storage and alternate storage .
the main functions of the base engine application programming interface ( api ) are : initialization and global definitions , image analysis functions , similarity comparison functions , scoring functions , and weights management . in addition to the functionality of the base engine , the extensible engine api also has primitive registration and schema management . the entry points for these functions are defined in regular

the vir system technology is built around a core module called the vir engine and operates at the image object level of the vimsys model . there are three main functional parts of the engine : image analysis , image comparison , and management . these are invoked by an application developer . typically , an application developer accesses them during image insertion , image query , and image requery ( a query with the same image but with a different set of weighting factors ) . the function of each unit , and how the application developer uses the vir application programming interface ( api ) to exchange information with the vir engine is described below . the full capabilities of the engine are decomposed into two api sets : a base vir engine , and an extensible vir engine . the base engine provides a fixed set of primitives ( color , texture , structure , etc . ) while the extensible engine provides a set of mechanisms for defining and installing new primitives ( discussed in detail later ) .

it is recommended that you back up your self - hosted engine environment regularly . the supported backup method uses the engine - backup tool and can be performed without interrupting the ovirt - engine service . the engine - backup tool only allows you to back up the red hat enterprise virtualization manager virtual machine , but not the host that contains the manager virtual machine .
this procedure provides an example of the workflow for backing up a self - hosted engine using a failover host . this host can then be used later to deploy the restored self - hosted engine environment . for more information on backing up the self - hosted engine , see section 3 . 10 . 1 , “backing up the self - hosted engine manager virtual machine” .

the nature of the self - hosted engine , and the relationship between the hosts and the hosted - engine virtual machine , means that backing up and restoring a self - hosted engine environment requires additional considerations to that of a standard red hat enterprise virtualization environment . in particular , the hosted - engine hosts remain in the environment at the time of backup , which can result in a failure to synchronize the new host and hosted - engine virtual machine after the environment has been restored .
although the extensible storage engine ( ese ) is a generic database engine , forensic analysis of ese databases seem to be centered around exchange . little information about forensic investigation of ese databases in general , seem to have been published in the public domain . as far as i can tell , mark woan author of esedbviewer , was one of the first who published information about forensic analysis of ese databases in general . this was in 2008 .
microsoft exchange server database uses extensible storage engine ( ese ) which is designed for single client - server architecture . the exchange server directly accesses the data from ese and the database here is stored in hierarchical storage format which includes the messages , folders , attachments , message properties etc . the data stored in each table may have varying property . the information store and ese collaboratively makes up client - server based messaging service for small and large enterprises .

drill uses various database optimizations such as rule based / cost based , as well as data locality and other optimization rules exposed by the storage engine to re - write and split the query . the output of the optimizer is a distributed physical query plan that represents the most efficient and fastest way to execute the query across the different nodes in the cluster . optimization in drill is pluggable , and you can provide rules for optimization at various parts of the query execution . storage plugins can expose optimization rules to drill , leveraging underlying storage engine features to achieve efficient execution .
has been used to deploy a new self - hosted engine and has restored the backup taken in the previous example procedure . deploying the restored environment involves additional steps to that of a regular self - hosted engine deployment :
the script creates the virtual machine to be configured as the manager virtual machine and provides connection details . you must install an operating system on it before the hosted - engine deployment script can proceed on hosted engine configuration .
after host 1 and the engine virtual machine have synchronized and the deployment has been finalized , the environment can be considered operational on a basic level . with only one hosted - engine host , the engine virtual machine is not highly available . however , if necessary , high - priority virtual machines can be started on host 1 .
the extensible storage engine ( ese ) is a database engine that stores information in a logical sequence . information can be retrieved either sequentially or by accessing defined indices . updates to the database are implemented with a transaction in order to ensure secure operations . ese enables simultaneous access to multiple databases , including transaction - log file databases that can be used for system recovery . ese is scalable to large or small applications . the following features are available with the ese application programming interface ( api ) :

at facebook we use mysql to manage many petabytes of data , along with the innodb storage engine that serves social activities such as likes , comments , and shares . while innodb provides great performance and reliability for a variety of workloads , it has inefficiencies on space and write amplification when used with flash storage . a few years ago , we built rocksdb , an embeddable , persistent key - value store for fast storage that has several advantages compared with innodb for space efficiency .
to support this , cassandra ' s storage engine provides wide , sparse rows . these rows can correspond 1 : 1 with business objects , but more often they encode data in the cell name as well as the value - - thus a
row
becomes more of an ( ordered ) map , than a relational row . this is the kind of model we had in mind when we improved the storage engine to allow up to two billion columns per row .
exchange mailbox databases and the queue on hub transport servers and edge transport servers utilize the extensible storage engine ( ese ) database . ese is a multi - user , indexed sequential access method ( isam ) table manager with full data manipulation language ( dml ) and data definition language ( ddl ) capability . ese allows applications to store records and create indexes to access those records in different ways .

despite its advantages , rocksdb does not support replication or an sql layer , and we wanted to continue using those features from mysql . this led us to build myrocks , a new open source project that integrates rocksdb as a new mysql storage engine . with myrocks , we can use rocksdb as backend storage and still benefit from all the features in mysql .
so , a storage group is a set of one or more database files that share a common set of log files .
several important operations occur at the start of exchange storage group backup process . here is the overview of the backup process :
image and video data are much more voluminous than text , and need supporting technology for rapid and efficient storage and retrieval .
if a hosted - engine host is carrying a virtual load at the time of backup , then a host with any of the matching identifiers - ip address , fqdn , or name - cannot be used to deploy a restored self - hosted engine . conflicts in the database will prevent the host from synchronizing with the restored hosted - engine virtual machine . the failover host , however , can be removed from the restored hosted - engine virtual machine prior to synchronization .
a unique name must be provided for the name of the host , to ensure that it does not conflict with other resources that will be present when the engine has been restored from the backup . the name hosted _ engine _ 1 can be used in this procedure because this host was placed into maintenance mode before the environment was backed up , enabling removal of this host between the restoring of the engine and the final synchronization of the host and the engine .
@ ejp but in practice it ' s true , on average , that there is wasted space , even for extensible hashing algorithms . a python dict consumes 50 % more buckets than required ( load factor of 75 % ) . and can you imagine the disk writes required to implement the ' extensible ' part of extensible hash tables ? all of a sudden you hit the limit and your db has to copy and rehash the entire table . and any tables to point to pks in that table , etc . so a single insert might ( unexpectedly ) put your db offline for a painful amount of time . that makes the ' extensible ' part impractical .
we always apply a reasonableness test . depending on what we know about the data , we’ll estimate storage requirement of roughly four times the storage reported in vsphere . in this case that 10tb . for this example , we’d recommend a repository with 8 to 10 tb of storage . this would allow for room to grow and would accommodate any unexpected data growth or high change rates .
after the packages have completed installation , you will be able to continue with restoring the self - hosted engine manager .
in many of its technologies like access or foxpro , microsoft uses the joint engine technology ( jet ) . there are two variants of jet engine : jet red and jet blue . microsoft office applications like access uses jet red that provides a standalone single user database . since it was not developed for a multi - user access and thus considering this limitation , the jet blue was developed that suited the multi - user requirement like exchange server . from the time this technology is used in exchange server , it has evolved to large extent and is incomparable to its original form . microsoft renamed this jet technology as extensible storage engine ( ese ) .

if the deployment of the restored self - hosted engine is on new hardware that has a unique name not present in the backed - up engine , skip this step . this step is only applicable to deployments occurring on the failover host , hosted _ engine _ 1 . because this host was present in the environment at time the backup was created , it maintains a presence in the restored engine and must first be removed from the environment before final synchronization can take place .

in another aspect of the invention , there is a method of extending a search engine for searching a database of visual objects , the method comprising the steps of providing a search engine primitive to extract an attribute from a visual object , and adding a new primitive to the search engine , wherein the new primitive comprises a comparison function for a selected attribute .
the extensible storage engine ( ese ) database format is mainly known for its use in the microsoft exchange , i . e . for the priv1 . edb file . what is less widely known that a lot of microsoft products use this file format , some of which are active directory ( ntds . dit ) , windows ( desktop ) search ( windows . edb ) and windows mail ( windowsmail . msmessagestore ) .
the base vir engine 120 has a fixed or default set of primitives . primitives and their weights are identified and indicated using a tagging mechanism to identify them in the api calls . the default primitives of the presently preferred base engine are :
a failover host , one of the hosted - engine hosts in the environment , must be placed into maintenance mode so that it has no virtual load at the time of the backup . this host can then later be used to deploy the restored self - hosted engine environment . any of the hosted - engine hosts can be used as the failover host for this backup scenario , however the restore process is more straightforward if host 1 is used . the default name for the host 1 host is hosted _ engine _ 1 ; this was set when the hosted - engine deployment script was initially run .
the hosted - engine script detects that the shared storage is being used and asks if this is an additional host setup . you are then prompted for the host id , which must be an integer not already assigned to a host in the environment .
impala does not currently support an extensible serialization - deserialization framework ( serdes ) , and so adding extra functionality to impala is not as straightforward as for hive or pig .
update your dns so that the fully qualified domain name of the red hat enterprise virtualization environment correlates to the ip address of the new manager . in this procedure , fully qualified domain name was set as urltoken . the fully qualified domain name provided for the engine must be identical to that given in the engine setup of the original engine that was backed up .
active directory is implemented on top of an indexed sequential access method ( isam ) table manager , historically called
jet .
this same table manager is used by exchange , file replication service ( frs ) the security configuration editor , certificate services , windows internet name service ( wins ) , and various other windows components . in windowsâ 2000 , this table manager is referred to as the extensible storage engine ( ese ) .
2 . the engine defined in claim 1 , wherein the primitive functions further comprise a comparison function to compare visual objects .
4 . the engine defined in claim 3 , further comprising an analysis function capable of deriving feature data from the object .
the vir engine is intended as an infrastructure around which applications may be developed . image management , thumbnails , database interfaces , and user interfaces are the responsibility of the application developer . in particular , persistent storage of feature vectors is up to the application .
ese is an advanced indexed and sequential access method ( isam ) storage technology for databases of allmost any size from kb to tb .
- backing the storage group up using either of the aforementioned methods will remove the unneeded log files providing you with extra disk space .
with salt , you’ve got a powerful python - based open source management and remote execution application . modular and easily extensible , salt maintains many module types to handle different actions .
cql3 makes one very important changes to how it presents cassandra data : wide rows are
transposed
and unpacked into named columns . from a relational standpoint , you can think of storage engine rows as partitions , within which ( object ) rows are clustered .
secure copy the backup files to the new manager virtual machine . this example copies the files from a network storage server to which the files were copied in section 3 . 10 . 1 , “backing up the self - hosted engine manager virtual machine” . in this example , urltoken is the fully qualified domain name of the storage server , / backup / enginebackupfiles is the designated file path for the backup files on the storage server , and / backup / is the path to which the files will be copied on the new manager .
modern versions of the edge browser no longer stores favorites as files / folders the way you may be accustomed to , and instead uses an internal extensible storage engine ( ese ) database to store favorites . this database is not designed to be
human readable
, so it takes specialized software to be able to do anything meaningful with it . so , this means that you can no longer use the file explorer to manage your favorites .
this procedure provides an example of the workflow for restoring the self - hosted engine environment from a backup . the failover host deploys the new engine virtual machine , which then restores the backup . directly after the backup has been restored , the failover host is still present in the red hat enterprise virtualization manager because it was in the environment when the backup was created . removing the old failover host from the manager enables the new host to synchronize with the engine virtual machine and finalize deployment . for more information on restoring the self - hosted engine , see section 3 . 10 . 2 , “restoring the self - hosted engine environment” .
the reserved transaction log files are created when the engine starts to allow important operations to be logged to get a clean shutdown .
connect to any of the hosted - engine hosts and turn off global maintenance mode . this enables the high - availability agents .
10 . the non - transitory computer - readable storage medium of claim 1 , wherein the embedded accumulator instructions are instructions for modular exponentiation .
the vir engine has a
stateless
architecture in which all of the data about images is managed and stored by the application . applications are responsible for passing
raw
image data ( e . g . , red , green , blue ( rgb ) format buffers ) into the engine , and then handling the feature data and scoring information that is returned to the application by the engine . when a comparison is desired , the application passes the feature data for a pair of images back to the engine to obtain a final score . thus , all persistent data management , query set management , and similar activities , are the responsibility of the application developer . the engine makes no assumptions about storage methodologies , formats , list management , or any information structures that require state information .
the names of the log files are dependent on a three - letter base name , which can be set with jet _ parambasename . the examples below use a base name of
edb
, because that is the default base name . the extension for the transaction log files will be either . log or . jtx depending upon whether the jet _ bitese98filenames is set in the jet _ paramlegacyfilenames parameter . for more information , see extensible storage engine system parameters .
the database engine attempted to replay a create database operation from the transaction log but failed due to an incompatible version of that operation .
microsoft access uses the jet (
joint engine technology
) database technology . in particular it uses the
jet red
database engine , which is a ( basically ) microsoft access specific fork of what was previously a microsoft windows
embedded database
library .
the engine virtual machine is running on host 2 and the six regular virtual machines in the environment are balanced across the three hosts .
to restore a self - hosted engine environment , you must prepare a newly installed red hat enterprise linux system on a physical host .
[ info ] engine replied : db up ! welcome to health status ! [ info ] waiting for the host to become operational in the engine . this may take several minutes . . . [ info ] still waiting for vdsm host to become operational . . .
the host is now able to host the manager virtual machine , and other virtual machines running in the self - hosted engine environment .
cassandra ' s distributed nature also influences the storage engine design . in particular , cassandra recognizes that distributed joins are performance killers : not only do they require lots of expensive random reads , but these reads have to be merged across the network , dramatically increasing the overhead involved .
i find exchange server to be a very complicated system and as in most complicated systems the most
trivial things
may bring it to its knees . one of these
trivial things
is lack of disk space on the disk that holds the log files for a specific storage group . when the information store identifies lack of disk space for a storage group ' s logs it will dismount the stores inside the respective storage group .
vanilladb is a collection of simple - to - read , fast , and extensible database system components aiming to lower the barrier of new - system prototyping and / or learning the database internals .
as a last step , use your favourite ide ( i use vim ) to replace “example” with “upscaledb” and “example” with “upscaledb” . don’t forget to change the cmakelists . txt file as well . then go to the root directory of mysql - server and once more run “cmake” and “make” . the new upscaledb storage engine is now built , the file name is mysql - server / storage / upscaledb / ha _ upscaledb . so .
the purpose of the extensible engine is to provide to the application developer the flexibility of creating and adding custom - made primitives to the system . for example , a face - matching system might construct primitives called
lefteye
and
righteye
, and provide an interface that compares faces based on the similarity of their eyes .
a first embodiment of the invention provides a
base vir engine api
which has a fixed set of visual primitives , and the necessary calls for analyzing and comparing images . a second embodiment of the invention provides an
extensible vir engine api
which allows application developers the ability to create new visual primitives for specialized , vertical applications . this enables application developers to capture higher level semantic information about the images being analyzed , and create intelligent applications in specific domains .

seoul , south korea – july 15 , 2015— hanwha q cells co . ltd . (
hanwha q cells
) ( nasdaq : hqcl ) today announced a new solar module supply agreement with sunrun , the largest dedicated residential solar company in the u . s . through the partnership , a subsidiary of hanwha q cells will provide sunrun with 50 mw of solar modules beginning this year . the cells and modules will be manufactured from hanwha q cells’ fully automated and efficient diversified global manufacturing facilities , including production in south korea starting in 2016 .
hanwha q cells produces panels in malaysia , china , and korea . they used to have a production line in germany , but they shipped the plant equipment to malaysia in 2012 , so hanwha q cells does not produce any german made panels .
q cells’ modules are highly competitive in the residential and commercial pv sectors , which have only begun to gurgle in china .
the board of directors at hanwha q cells is committed to maintaining the highest standards of corporate governance . the board of hanwha q cells has developed corporate governance the practise to fulfill its responsibility to hanwha q cells stockholders . as part of these practices , the board has adopted the following corporate governance charters to help ensure that it has the necessary authority and procedures in place to oversee the work of management and to exercise independence in evaluating hanwha q cells ' business operations . these charters allow the board to align the interests of directors and management with those of hanwha q cells corporation ' s stockholders , whilst they are subject to future refinement or changes as the board may find necessary or advisable for hanwha q cells in order to achieve the above objectives .
hanwha q cells has been awarded the pv magazine award 2017 for its innovative steel frame solar module q . peak rsf l - g4 . 2 , a monocrystalline q . antum module with easy mounting system , reinforced steel frame and decentralised junction box .
hanwha q cells has reached positive operating results in the first quarter of 2014 and is now the largest european pv provider , the company reports . after struggling to remain profitable in 2012 , german - company q cells was sold to south korean conglomerate hanwha .
q cells is one of the most popular and well - known brands of modules in the photovoltaic industry in europe and australia .

add to that the 800mw of module capacity that q cells is building in malaysia , and the combined company will have all the benefits of solarone’s low - cost chinese production alongside q cells’ ability to sell modules to the us and europe without fear of trade barriers .
i applied online . the process took a week . i interviewed at q - cells ( cyberjaya ( malaysia ) ) in may 2012 .
the combined company will have a strategically diversified manufacturing footprint that provides significant competitive advantage . q cells brings award - winning technology and manufacturing from
executive headquarters will be located in seoul , korea , and its technology and innovation headquarters in thalheim , germany , home to q cells .
yet by swallowing q cells , solarone will have an unassailable claim to being the world’s largest maker of pv cells – catapulting past companies like yingli , trina and ja – and one of the largest module suppliers .
hanwha q cells describes their q cells panels as “engineered in germany” . while they no longer manufacture panels in that country , their headquarters for research and development are in germany and i have been told they have over 200 experts there working to improve the design and production of solar panels .
an above average product warranty with a competitive price makes hanwha q cells a good choice and i have no problem at all in recommending them .
in february 2015 hanwha q cells co . , ltd . ( nasdaq : hqcl ) emerged as a new global solar power leader from combining two of the world´s most recognized photovoltaic manufacturers , hanwha solarone and hanwha q cells . the combined company is listed on nasdaq under the . . .

hanwha q cells also have 3 other research and development centers around the world . if you are wondering where those centers are located , i will quote the chairman and ceo of hanwha q cells , seong woo nam . on the promotion of their new chief technology officer ( cto ) in july 2016 , he said :
the overdue merger of china’s solarone and germany - and malaysia - based q cells solves problems for both companies , though it by no means guarantees their future .
hanwha q cells applies good corporate governance principles to multiple areas of the company . in addition to these guidelines , hanwha q cells has a code of business conduct and ethics and the board has also adopted charters for each of the following standing board committees : audit committee , compensation committee , and nomination and governance committee .
the q cells q . pro bfr - g4 . 1 sc 265 265w pv module boasts it ' s top performances , the new q . peak blk - g4 is the aesthetic model photovoltaic module . the fourth module generation from q cells has been optimized across the board : improved output yield , higher operating reliability and durability , quicker installation and more intelligent design . the new q . pro bfr - g4 . 1 is the result of the continued evolution of our q . pro family . thanks to improved power yield , excellent reliability , and high - level operational safety , the new q . pro bfr - g4 generates electricity at a low cost ( lcoe ) and is suitable for a wide range of applications .
they are the same company with different divisions . hanwha purchased q cell in 2013 and is managing it as a stand alone business unit . q cells will be strong in the north american market and hanwha will pull back efforts on the us market .
the datasheets for q cells panels gives their highest efficiency as 16 . 8 % , but do not clearly show their corrosion resistance certification . but , matt scadden , the sales manager of hanwha q cells australia , assures me they are fully certified for corrosion resistance and , like the hanwha solar panels , are suitable for installation anywhere in australia .
as a photovoltaic manufacturer , q cells engineers its award winning and certified solar modules in germany . we guarantee maximum output even in ambient light conditions . rely on the test winner
the merger of hanwha solarone and hanwha q cells is set to proceed in a deal estimated to cost hanwha solarone around us $ 1 . 2 billion in an all - stock transaction .
q cells solar products are way ahead of the competition when it comes to quality , as testified by a wide variety of awards , certificates and world records for efficiency . we set the standards
q - cells have told me that 2016 sales are on track to sell their entire annual capacity of 5 . 4 gigawatts , which if true will advance them from 5th place in 2016 .
“we feel honored that our customers consistently put their trust in hanwha q cells . ” says maengyoon kim , head of module sales in europe at hanwha q cells . “winning the seals for the fourth year in a row in europe and for the second time in australia spurs us to continue our work with the utmost commitment to offer our customers best quality and service , ” he emphasized .

q cells ' commitment to quality , technology , and innovation has enabled us to become one of the most respected solar companies with a world - renowned product reputation and downstream expertise . the merger with solarone creates a truly global platform that will provide us with a platform to achieve greater economies of scale and facilitate expansion into important solar markets including
the company has gained further market share in its european home markets and in its single largest market , japan . in europe the united kingdom is an especially important market for the company followed by france and germany . at the same time hanwha q cells japan has reached the position as the leading foreign pv provider in japan , the company reports . moreover , hanwha q cells has been expanding its power plant solutions business . on the basis of the company´s track record of around 700mw of installed capacity in large scale power plants hanwha q cells has realized projects in the europe , the americas and asia .
q - cells are performing above my expectations , just make sure you clean your panels if it hasn ' t rained heavily for a several weeks . bought from : solargain review date : 26 august 2016
so expect solarone , whose efforts to diversify into project development have not yet paid off in any meaningful way , to attempt to ride q cells’ experience and reputation into attractive project markets around the world .
it is worth remembering , too , that long before its financial difficulties , q cells had made a name for itself as a premier project developer and epc contractor – with a significant footprint in the us .

the german solar industry is at a turning point . the bankruptcy of q - cells this week shows that the days of german solar cell production are numbered . asian competitors took the lead years ago , and german government subsidies were part of the problem .
during the company´s first full year , 2013 , hanwha q cells has strengthened teams at its headquarters in germany as well as at its mass production site in malaysia and increased its international sales force in order to satisfy the growing global demand . in 2014 the pv specialist has opened new offices in france as well as in the emerging markets turkey and chile . thus hanwha q cells has increased its global headcount from 1 . 225 employees at the launch of the company in october 2012 to approximately 1 . 350 employees at present .
charles kim , chief executive of q cells , said :
q cells ' commitment to quality , technology , and innovation has enabled us to become one of the most respected solar companies with a world - renowned product reputation and downstream expertise . the merger with solarone creates a truly global platform that will provide us with a platform to achieve greater economies of scale and facilitate expansion into important solar markets including china . together with solarone , we look forward to delivering superior solar solutions to our customers and growing our global leadership position .
q cells ' 1 . 5gw of cell capacity , located primarily in malaysia , is top - shelf quality , and comes with an

brand that is known and respected in many established pv markets where solarone ' s own kit is seen as a commodity product .
the deal struck will see hanwha solarone acquire 100 % of the outstanding share capital of q cells from its sole shareholder , hanwha solar holdings ( hsh ) , in an all - stock transaction with an implied enterprise value of the combined entities of approximately us $ 2 . 0 billion .
solarone noted that its solar cell and pv module production capacity was 1 . 75gw and 2 . 07gw , respectively , while q cells ' solar cell and pv module manufacturing capacity are 1 . 53gw and 130mw respectively , with plans to expand capacity further in 2015 of 800mw of modules .

we ' re very excited to have dr . daniel jeong as our new cto , who has demonstrated an outstanding leadership in integrating our global r & d teams located in germany , malaysia , korea and china following the merger between former hanwha q cells and hanwha solarone in early 2015 . ”
seongwoo nam – who is currently chief executive of solarone , and will be chairman and ceo of the newly merged company – is justified in saying that the combined company will be a “formidable global leader” . on their own , neither q cells nor solarone have rightly been able to make that claim .
now the german - headquartered pv solutions specialist achieved growing revenues and positive earnings before interests and tax ( ebit ) in the first three months of 2014 . moreover hanwha q cells has taken the lead among european pv companies with total shipments of 247mw and a module production volume of 244mw in q1 2014 .
it wasn ' t so long ago that people viewed q - cells as an energy company of the future . at one point , it was the world ' s largest manufacturer of solar cells and quarter after quarter , it topped analysts ' expectations . the company proved to be a money - making machine even during the financial crisis , with some believing it might one day grow to become part of germany ' s dax index of benchmark companies on the stock exchange .
expansion into downstream : the combined company will expand into downstream initially leveraging 2 . 17 gigawatt global downstream pipeline ( including 1 . 12 gigawatt pipeline under partnership with hanwha - affiliated companies ) , of which 30 % is in late stage and q cells ' more than 700 megawatt of project installation expertise since 2007 .
q . flat - g4 is more than just a substructure for flat roofs : it forms the basis for an entire system solution from a single source .
hanwha q cells is a major manufacturer of solar panels . in 2015 they produced 3 . 2 gigawatts , making them the 5th largest manufacturer of tier one solar panels in that year ( just so long as you think gcl systems were slumming it in 2015 and were not yet worthy to be called tier 1 ) .
margins are falling across the solar industry as the rapid reduction in panel prices is hitting manufacturers ' income statements . previously reported earnings from competitors canadian solar , jinkosolar , and ja solar have all showed a consistent decline in results and even losses on the bottom line . but hanwha q cells ' results were particularly bad .
from q cells ' perspective , perhaps the most obvious advantage to the merger is the chance to begin pushing its brand in china , the world’s largest solar market . solarone derived 30 % of its module revenues from china last quarter , and has aspirations to be a major player in the distributed - generation market there .

our modules possess the quality and high - efficiency characteristics that sunrun requires for its customers ,
mr . lee also added ,
this contract , combined with other previously announced supply agreements , has further strengthened our position as one of the leading suppliers of solar modules to the u . s . market .
this supply agreement follows hanwha q cells’ recent successful combination with hanwha solarone co . , ltd . to form a global leader in solar power and further validates the financial stability , advanced technology , and manufacturing leadership of the new company
, mr . lee concluded .
according to the statement , the combined company is planning to expand its downstream ambitions , an area solarone has been trailing rivals . combining q cells long - standing downstream expertise , solarone said it would have a pv project pipeline of 2 . 17gw , which included 30 % of hanwha - affiliated companies projects that were said be ‘late stage’ developments .
eupd research emphasized that participating installers rated the products from hanwha q cells positively as compared to the competition . furthermore , the scores for brand recommendation and unaided brand awareness were among the highest in the industry . only a small number of manufacturers were honored with the top brand pv seal , but rarely have companies qualified for a majority of the surveyed markets .
q - cells is the best example . the company first began outsourcing large shares of its production to malaysia in the summer of 2011 . by then , it had been clear for years that germans could no longer compete with asian firms in the sector . the writing had long been on the wall and it didn ' t take a clairvoyant to see it .
meanwhile , asian companies continue to steam ahead of their german competitors . in 2008 , china manufactured 33 percent of the world ' s solar cells , but that figure grew to 57 percent last year . this week , the german government significantly reduced its subsidies for promoting solar energy . but the boom in cheap cells will continue and it will radically change the solar energy market .
according to the terms of the transaction , solarone will issue approximately 3 . 7 billion solarone ordinary shares ( being the equivalent of approximately 740 . 2 million american depositary shares ) to hsh in exchange for the transfer of 100 % of the outstanding share capital of q cells by hsh to solarone . the new shares to be issued by solarone to hsh in the transaction represent approximately 8 . 09 newly issued shares for each of solarone ' s currently outstanding shares on a fully diluted basis . if consummated , the transaction would result in hsh increasing its ownership of solarone from approximately 45 . 7 % to approximately 94 % , in consideration of hsh ' s transfer of full ownership of q cells to solarone . based on solarone ' s
on the bright side , a single contract announced today could account for nearly a quarter ' s worth of demand . if hanwha q cells can cut costs enough , it may be able to bring back profits , but there ' s no guarantee - - even after winning a contract that will account for a large percentage of the next year and a half ' s supply .
these are good quality cells with decent efficiency . decent output even at low solar angles , which is helpful for those of use living in tasmania . bought from : green sky australia review date : 11 march 2018

at the end of 2007 , the company was valued at close to 8 billion ( $ 10 . 7 billion at today ' s rates ) . q - cells ' production facilities were located in the city of bitterfeld - wolfen , in a former lignite mining area in the eastern german state of saxony - anhalt . the area was even dubbed
solar valley ,
a play on california ' s silicon valley .
but q - cells ' insolvency also comes as a great shock to the germany ' s solar industry . it is already the fourth major bankruptcy in a sector in crisis , and it underscores the degree to which german solar firms are being outpaced by competition from asia - - despite billions in german government subsidies granted each year to the industry . and despite solar energy gradually becoming more competitive , the setbacks are rapidly mounting .
hanwha group started in south korea as hanwha explosives inc . in 1952 and rapidly exploded into a massive international conglomeration . they acquired the german company q cells and its solar panel manufacturing capacity in germany and malaysia when it became insolvent in 2012 . they also acquired solarfun , which was a chinese panel manufacturer . not wanting to be mistaken for a bunch of clowns , they changed the name of solarfun to hanwha solar one .

the change can also be seen in the case of solar millennium , a company that didn ' t even produce solar cells . rather , it built solar thermal power plants that transformed solar energy into thermal energy . unfortunately , it ' s a technology that has recently been put on the back burner because of the availability of inexpensive photovoltaic cells . solar millennium suffered a number of setbacks when projects planned in the united states failed to materialize .
there ' s really no bright sign right now for commodity solar suppliers like hanwha q cells . the industry is oversupplied , demand is falling in the short term , and margins are dropping , leading to financial losses . that ' s not a good position for any company to be in , particularly when new technology like mono - perc and other high - efficiency options are becoming more highly valued than the panels manufacturers have typically made .
their panels are tier 1 and have a 12 year product warranty which is 20 % longer than the 10 year product warranty most panels carry . hanwha q cells has an australian office in sydney , their panels are salt mist corrosion resistant and so are suitable for installation anywhere , and at the time of writing in october 2016 they appear to have the lowest price per watt of any panel that carries a 12 year or better product warranty .
its corporate headquarters will moved from the outskirts of shanghai to seoul ( where the company will open a new 230mw module plant in mid - 2015 ) . its “technology and innovation” headquarters will be kept in thalheim , germany – the historic home of q cells , and where it still employs more than 200 researchers and engineers . its shares will trade on new york ' s nasdaq exchange . and it will still employ many thousands of factory workers in china .
for a some time now , though , the days have been growing darker in solar valley , and with this week ' s bankruptcy announcement by q - cells , things are looking to get even darker . on tuesday , the company as expected submitted its official request to begin bankruptcy proceedings . the energy company of the future looks as though it may no longer have one . the company , it turns out , simply wasn ' t prepared for the fast changes that have buffeted the industry .
hanwha claimed the combined entity would become the world ' s largest manufacturer of solar cells with a capacity of 3 . 28gw . according to npd solarbuzz data before the ihs acquisition , yingli green had become the largest solar cell producer in 2013 for the first time with production in excess of 2gw .
solarone ' s board of directors , acting upon the unanimous recommendation of the special committee ( the
special committee
) formed by its board of directors , approved the share purchase agreement for the transaction and resolved to recommend that solarone ' s shareholders vote to approve the transaction . the special committee , which is comprised solely of independent directors of solarone who are unaffiliated with q cells , hanwha solar holdings co . , ltd . (
hsh
) , hanwha chemical corporation or any of the management members of solarone , negotiated the terms of the purchase agreement with the assistance of its financial and legal advisors .
in technological terms , solar cells are relatively easy to copy and manufacture , and germany , with its comparably expensive labor market , is no longer the place to produce them . much of the manufacturing of solar cells in germany is already automated , but it is still considerably cheaper to operate a factory in a country like china , where costs are lower for everything from factory construction to paying the cleaning crew . in addition , beijing has made the solar sector a priority and the government is providing many manufacturers with loans at highly favorable interest rates . even worse , the german government has also directly and indirectly subsidized chinese solar companies to the tune of 100 million as part of development aid efforts aimed at promoting china ' s green industries .
with its top performance and completely black design the new q . peak blk - g4 . 1 is the ideal solution for all residential rooftop applications thanks to its innovative cell technology q . antum . the world - record cell design was developed to achieve the best performance under real conditions – even with low radiation intensity and on clear , hot summer days . low electricity generation costs higher yield per surface area and lower bos costs thanks to higher power classes and an efficiency rate of up to 18 . 0 % . innovative all - weather technology optimal yields , whatever the weather with excellent low - light and temperature behavior . enduring high performance long - term yield security with anti - pid technology1 , hot - spot - protect and traceable quality tra . q™ . extreme weather rating high - tech aluminum alloy frame , certified for high snow ( 5400pa ) and wind loads ( 4000pa ) regarding iec . maximum cost reductions up to 10 % lower logistics costs due to higher module capacity per box . a reliable investment inclusive 12 - year product warranty and 25 - year linear performance guarantee2 .
in the medium term , fierce competition with asian companies will also likely affect other parts of the solar energy industry in germany . for example , it could hit companies like centrotherm , which manufactures machines that are used in the automated production of solar cells . development of that equipment is certainly more complex , but asian manufacturers are already presenting an increasing number of products at industry trade shows like intersolar .
the cut - throat nature of the competition , of course , is nothing new . but in recent years it has been hidden by the german boom in demand from 2009 to 2011 , the result of generous efforts from berlin to promote solar power . even companies that had fallen behind the asian competition were having no trouble moving large quantities of solar cells . the situation is reminiscent of coyote running off a cliff while chasing roadrunner , running in mid - air for a few seconds and then plummeting into the abyss .
saferay was founded in 2010 by an experienced team which had previously built q - cells international from scratch into the largest system integrator of solar plants in the world within 2 years . the team ' s mission is to create a new kind of independent power producer that solely focuses on solar pv . the team has completed more than 700 mw of utility - scale solar plants on five continents : europe : italy , france , czech republic , germany , uk , spain americas : canada , usa , mexico , chile asia / pacific : japan , australia saferay developed rapidly during the first two years of existence , building 45 mw during the first six month of its existence , and adding another 125 mw in the first full year of operation . the company keeps most of the powerplants on its own balance sheet . saferay is fully privately owned and has no third party investors , which allows for fast decision making and clear focus . the company is currently active in germany , chile , mexico , the us , japan , singapore and australia .
