description: Micromegas detector is considered to be a promising candidate for a large variety of high-rate experiments. Micromegas of various geometries have already been established as appropriate for these experiments for their performances in terms of gas gain uniformity, energy and space point resolution, and their capability to efficiently pave large read-out surfaces with minimum dead zone. The present work investigates the effect of spacers on different detector characteristics of Micromegas detectors having various amplification gaps and mesh hole pitches. Numerical simulation has been used as a tool of exploration to evaluate the effect of such dielectric material on detector performance. Some of the important and fundamental characteristics such as electron transparency, gain and signal of the Micromegas detector have been estimated.

description: In this practice-led thesis, I argue that the powerful potential of performance art lies in the dynamic character of its process, evolving according to forces of fragmentation and union; this leads those involved in a performance to experience reconfiguration in their perceptions, thoughts, and emotions. By examining the dynamics occurring during the unfolding of a piece, exploring the essence of its “happening”, I aim to offer a deeper understanding of how performance art engages with the world. I do so by investigating some key moments of the processes of five artworks in combination with scholarship encompassing various research fields.

description: We present a fast and simple 1D simulation tool to predict solar cell performance as a function of the
initial iron content and distribution in the as-grown silicon wafer, the time-temperature profiles applied during the
fabrication process, and several parameters related to cell architecture. The applied model consists of three parts that
are validated by comparison to experimental results from literature. Assuming a time-temperature profile of a standard
solar cell fabrication process, we calculate the redistribution of iron and the evolution of minority carrier lifetime for
different as-grown Fe distributions. The solar cell performance as a function of the total iron concentration and the final
lifetime distribution is also simulated and compared to experimental results for multicrystalline Si.
Medida privativa de la libertad en centro carcelario : ¿es necesaria para retirar del cargo a funcionarios públicos?

description: Las medidas de aseguramiento son herramientas dispuestas por el legislador para salvaguardar estrictamente fines constitucionales. Para ello, la misma Constitución Política de Colombia, en su Artículo 250, facultó a la Fiscalía General de la Nación para ejercer la acción penal, y con ella poder solicitar estas medidas cuando se considere posible que el investigado no comparezca al proceso, se pueda ver afectada la conservación de la prueba, o se pretenda proteger a la comunidad y en especial a las víctimas, exigiendo para ello siempre que se soporte los elementos materiales probatorios. Sin embargo, en la actualidad, las privativas de la libertad resultan ser las principalmente invocadas por el ente acusador, al punto de que, en la práctica, son casi una regla general, y las no restrictivas son la excepción. Cuando el investigado es un funcionario público lo anterior puede tener su razón de ser en el hecho de que, hoy día, con la finalidad de evitar la continuación de su actividad delictual, o las labores que emprenda para ocultar, destruir o deformar elementos probatorios importantes para la instrucción, o entorpecer la actividad probatoria, no existe en la Ley 906 de 2004 una medida de aseguramiento consistente en el retiro del cargo.
description: Security measures are tool provided by the legislator to strictly guard constitutional aims. To this end, the Constitution of Colombia in its Article 250 empowered the Attorney General's Office to exercise criminal action measures, and with it to be able to request remand when it is considered possible that (i) the investigated person would not appear at the trial, (ii) the preservation of the evidence could be jeopardized, (iii) the community needs protection, and especially the victims. The aforementioned always requiring that the material elements of evidence be justified. However, remand measures currently turn out to be the only security measures invoked by the prosecuting entity, to the point that, in practice, they are almost a general rule, and the nonrestrictive ones are the exception. When the person under investigation is a public official, the above may have its reason in order to prevent the continuation of his criminal activity, or to avoid hiding, destruction or distortion of important elements of evidence for the investigation, since Law 906 of 2004 does not include a security measure consisting of the withdrawal of the charge. This have paved way for the prosecution officers to justify invoking remand as a rule (and not as exception as established by law) when public officials are being investigated, leading to the distortion of criminal law principles.

Large PV Power Plants and High Penetration of Distributed PV: System Aspects and Grid Integration

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5022-5024
description: In this paper, we present an application of Artificial Neural Networks (ANNs) in the renewable energy
domain. We particularly look at the Multi-Layer Perceptron (MLP) network which has been the most used of ANNs
architectures both in the renewable energy domain and in the time series forecasting. We have used a MLP and an adhoc
time series preprocessing to develop a methodology for the daily prediction of global solar radiation on a
horizontal surface and a 1.175 kWp PV plant production. Different forecasting methods are compared: a naïve
forecaster like persistence, an ANN with preprocessing using only endogenous inputs and an ANN with
preprocessing using endogenous and exogenous inputs (like temperature, pressure, nebulosity, insulation, wind speed
and direction etc.). The endogenous case is easily computed: the use of Partial Auto Correlation Factor (PACF)
allows to optimize the number of lag time to consider. For the exogenous variables, we have applied a Pearson
correlation coefficient method to optimize the number of considered input neurons. Although intuitively the use of
meteorological data in the input layer of the MLP can only increase the quality of prediction, the obtained results are
relatively mixed. The use of exogenous data generates a decrease of nRMSE between 0.5% and 1% for the both
studied locations. The absolute error (RMSE) is decreased by 52 Wh/m²/day in the simple endogenous case and 335
Wh/m²/day for the persistence forecast. The results are similar to the concrete case of a tilted PV wall (1.175 kWp),
endogenous and exogenous data ANN inputs allow decreasing the nRMSE by 1% on a 6 months-cloudy period for
the direct current (DC) power production (January-June). Moreover, the use of exogenous data shows an interest in
cloudy period (winter season). In summer, endogenous data as inputs on a preprocessed ANN seem sufficient. By
comparison to a naïve forecaster as persistence, an ANN with endo and exogenous data improves the DC electrical
power energy prediction by 9% (nRMSE). Next step of this work will drive to shorter horizons; power predictor of
meteorological data should have a greater impact.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5046-5049
description: The Canary Islands are a Spanish archipelago located in the Atlantic Ocean, just off the northwest
coast of mainland Africa, at around 100 km west of Morocco-Western Sahara and, therefore, at nearly tropical
latitude. Due to its proximity with Sahara desert, quite frequently, the Canary Islands receives the visit of “Calimas”,
which are dust hazes caused by dust storms stirred up by high winds in the Sahara, which are driven over the Canary
Islands by south easterly winds. Such winds carries fine sand particles, causing the air to become thick and visibility
turning rather like that experienced during a thick fog, depending on the severity. Also, these sand particles tend to
cover every surface with a fine reddish brown layer.
Therefore, we have been studying how the arrival of Saharan dust hazes produces a change in the atmosphere
conditions, such as in the ambient temperature, humidity and, specially, in the radiation, in order to address their
effect in the performance of multi-MW PV grid connected facilities, which preliminary data suggest may be
responsible for a reduction of around a 5% off their output power capabilities.

description: Reverse IV-characteristics of CIGS based solar cells have an impact on the reliability of these devices as
during shadowing of single cells in a module a high reverse bias can develop leading possibly to a junction damage and hot
spots. In this study the reverse current characteristics of highly efficient solar cells and integrated modules were investigated
and correlated to the occurrence of metastabilities of these thin film solar cells. The reverse IV-characteristics can be
modelled by a reverse diode which limits the bias during shadowing of single devices. By optimization of the operating
conditions this reverse bias can be minimized. Modelling of the junction characteristics indicates that interface properties are
responsible for the measured reverse currents.

description: The distributed generation (DG) connected to the distribution level of electric power systems is growing rapidly
worldwide. This can produce great improvements in power system performance. However, it also causes new problems. These
possible positive and negative impacts of DG mainly depend on the DG type, distribution network configuration, operation mode,
and load profile. This paper presents analysis of PV distributed generation impact on fault quantities in case of unbalanced faults
occurring at the host network. The fault simulations are conducted using the German distinguished program Power Factory
DigSilent V14.0.506. At each bus the voltage and the current changes at the time of the fault are recorded. A PV generator is
added to the system and is located at various buses for each fault and the impact of the PV on the fault voltage and current
quantities is recorded. The simulations have shown that the voltage magnitude of the healthy phases (b and c) during the phase ato-
ground fault increases to more than 1.07 per unit, especially when the fault is close to the PV unit. Moreover the presence of
PV unit will increase the fault level at PV-Bus by about 17%.

description: The friction and diffusion coefficients of rigid spherical colloidal particles dissolved in a fluid are determined from velocity and force autocorrelation functions by mesoscale hydrodynamic simulations. Colloids with both slip and no-slip boundary conditions are considered, which are embedded in fluids modelled by multiparticle collision dynamics (MPC) with and without angular momentum conservation. For no-slip boundary conditions, hydrodynamics yields the well-known Stokes law, while for slip boundary conditions the lack of angular momentum conservation leads to a reduction of the hydrodynamic friction coefficient compared to the classical result. The colloid diffusion coefficient is determined by integration of the velocity autocorrelation function, where the numerical result at shorter times is combined with the theoretical hydrodynamic expression for longer times. The suitability of this approach is confirmed by simulations of sedimenting colloids. In general, we find only minor deviations from the Stokes-Einstein relation, which even disappear for larger colloids. Importantly, for colloids with slip boundary conditions, our simulation results contradict the frequently assumed additivity of local and hydrodynamic diffusion coefficients.

description: Research on CIGS-based photovoltaic cells is developing towards the use of wide band-gap and non-toxic
materials to replace the cadmium sulphide buffer layers that is used as an interfacial buffer layer. Efficiency level of 15-16 %
has been reached using CBD-Zn(S,O,OH)/rf-(Zn,Mg)O buffer layers. However contrary to cells with CdS buffer layer, CBDZn(
S,O,OH)/rf-ZnMgO cells require post-air-annealing and light-soaking procedures to achieve optimal conversion
efficiencies. This paper addresses the optoelectronic parameters affected by these post-treatment effects. First the impact of
heat treatment and light soaking has been studied by comparing the properties of different combinations of CBD-CdS, CBDZn(
S,O,OH), rf-i-ZnO, rf-ZnMgO, layers. The gradual impact of light soaking on CIGS/CBD-Zn(S,O,OH)/rf-
ZnMgO/ZnO:Al solar cell characteristics has been analyzed prior to and after annealing, revealing a dominant improvement
in the fill factor. Temperature dependant current-voltage measurements and voltage dependent spectral responses
measurements are also presented. This suggests that recombination losses at the interface are the initially dominant
mechanism which is cured by post treatments leading to bulk recombination controlled devices.

description: The behavior of hydrogen in iron and iron alloys is of interest in many fields of physics and materials science. To enable large-scale molecular dynamics simulations of systems with Fe-H interactions, we develop, based on density-functional theory calculations, an interatomic Fe-H potential in the Tersoff-Brenner formalism. The obtained analytical potential is suitable for simulations of H in bulk Fe as well as for modeling small FeH molecules, and it can be directly combined with our previously constructed potential for the stainless steel Fe-Cr-C system. This will allow simulations of, e.g., hydrocarbon molecule chemistry on steel surfaces. In the current work, we apply the potential to simulating hydrogen-induced embrittlement in monocrystalline bulk Fe and in an Fe bicrystal with a grain boundary. In both cases, hydrogen is found to soften the material.

description: a) Topics and Objectives. The objective of our project is to describe with greater precision than previously the expansion of antique Christianity against the background of two orienting categories, namely »space« and »knowledge«. To this end, the members and Fellows of our group analyze epigraphic and literary materials, but also findings pertaining to the archaeology, religious geography, and biogeography of selected regions of the Roman Empire and evaluate these in terms of a range of concepts of space. b) Methods. Data collection and historical-critical analyses of epigraphic and literary materials; incorporationof findings pertaining to the archaeology, religious geography, and biogeography of the respective regions; pluralism regarding conceptions of space. Noteworthy in particular in this context is the fundamental research of PD Dr. Ulrich Huttner, who has developed a databank of early Christian inscriptions from Asia Minor which draws upon a continuously growing collection of data. c) Current state of the discussion within the research group. No attempt is being made to coordinate our respective findings in terms of a single metatheory vis-à-vis space. Instead, physical, historico-political, social, and post-structural concepts of space are juxtaposed and contrasted with one another and deployed depending upon the respective point of departure.

description: We have studied theoretically the optimum temperature for intrinsic gettering of iron by as-grown iron
precipitates in multicrystalline silicon. Simulations were done with two different cooling rates during crystal growth and with
and without the gettering effect of a solar cell emitter diffusion. In slowly cooled crystals and in rapidly cooled crystals with
low initial iron contamination level where the iron precipitate density after PDG is low, gettering to the emitter is
pronounced. Under conditions of high initial iron contamination level and high iron precipitate density caused by fast
cooling, the intrinsic gettering dominates. Due to higher precipitate density the optimal gettering temperature is also lower
than in the case of slowly cooled crystal.

description: This study examines the socioeconomic and cultural adaptation of Jewish migrants from the former Soviet Union who settled in Melbourne between 1975 and 1999. They mainly migrated to Australia under specially devised humanitarian visas. Soviet Jews had been subject to discrimination resulting in their distinct secular ethnic identity. Their socioeconomic adaptation is analysed by comparing them to other migrant groups and to the Australian-born population. Their cultural adaptation is examined by comparing their religiosity, Jewish ethnic belonging, and participation in Jewish communal life to Australian-born Jews and to Jewish migrants from Israel and South Africa.

description: Light-induced degradation (LID) due to boron-oxygen complex formation seriously diminishes the
minority carrier lifetime of p-type Czochralski-grown (Cz) wafers. Depending linearly on the boron concentration NA in
uncompensated silicon, the boron-oxygen defect density was suggested to depend on the net doping concentration p0 =
NA-ND in compensated p-type samples, containing similar amounts of boron and phosphorus [1]. However, this
dependence contradicts observations of LID in compensated n-type silicon wafers [2], which are confirmed in this study
by investigating the boron-oxygen complex formation on a large variety of compensated p- and n-type samples. In spite
of their high boron content, compensated n-type samples show a less pronounced LID than p-type samples containing
less boron. Our experiments indicate that in compensated Cz silicon, the defect concentration is only a function of the
compensation ratio RC = (NA+ND)/(NA-ND) and may be described consistently in compensated p- and n-type Cz-Si by an
exponential decay. Beyond these fundamental effects, the lifetime study reveals on a variety of compensated p-type Cz
crystals from industrial solar-grade feedstock that there are no feedstock-related losses in material quality in addition to
the intrinsic losses due to LID. By manufacturing solar cells in an industrial solar cell process this is confirmed by stable
degraded cell efficiencies of 17.4% which are achieved on average over the whole crystal length on crystals made from
feedstock with and without blend of 33% SoG feedstock.

description: Boron doped p-type Czochralski (Cz) silicon solar cells undergo efficiency degradation under
illumination. The light induced degradation (LID) is related to the formation of Bs-O2i complexes in the bulk of Si
which act as strong recombination centers. In this paper, Sixtron Advanced Materials Inc. introduces its patentpending
Silexium technology using SiH4-free solid or liquid source, a PECVD SiCN antireflective passivation
coating which can reduce LID significantly in Cz-Si solar cells. This LID reduction may be related to carbon atoms
which diffuse into the Si bulk from the SiCN film. Namely, the in-situ grown carbon in the SiCN film provides a
source of additional carbon which gets incorporated into the bulk silicon during the cell processing. This carbon
competes with boron to form a carbon-oxygen related complex and reduces the Bs-O2i concentration and the
associated LID compared to conventional SiN coated solar cells. The SiCN coated solar cells studied here showed 1
to 2% relative efficiency reduction after several hours of illumination compared with 1 to 6 % relative efficiency drop
for SiNx coated counterparts on a variety of boron doped Cz-Si materials with varying oxygen content.

description: In this paper, the results of a degradation analysis over a sample of 17 PV systems with
monocrystalline, polycrystalline and EFG modules are presented. The systems have a total installed power of
10 MWp and have been in operation for more than 5 years each. By analyzing long-term time series and extracting
data points at similar environmental conditions rates of change for Performance Ratio and solar generator efficiency
were derived. As drifts of irradiance sensors can considerably affect the results of a long-term analysis, we performed
sensor recalibrations for all systems in the study. Results of the recalibration of 85 sensors in total are presented.
Sources of uncertainty are discussed. The findings are that it is not necessary to account for a general dropping
module efficiency for mono and polycrystallinesilicon.

description: Forecasting is a key activity for any business to operate efficiently. It is becoming increasingly common to have to regularly forecast many millions of time series. The dramatic increase in the availability of large collections of time series raises the need for developing reliable efficient and automatic algorithms for forecasting. This thesis presents three such algorithms for large-scale applications based on the meta-learning approach. Each of these algorithms uses vectors of features computed from time series to guide the way the forecasts are computed. The results show the proposed algorithms perform well compared to competitive methods in large forecasting competitions.

He applied state of the art high angular resolution techniques, such as optical interferometry and adaptive optics imaging, to the the study of a variety of objects, from AGB stars to Planetary Nebulae, via e.g. Born Again stars, RCB stars and Novae. I present here an overview of this work and most important results by focusing on the paths he followed and key encounters he made to reach these results. Olivier liked to work in teams and was very strong at linking people with complementary expertises to whom he would communicate his enthusiasm and sharp ideas. His legacy will live on through the many people he inspired.

description: We review the mathematical tools required to cull and filter representations of the Coxeter Group $BC_4$ into providing bases for the construction of minimal off-shell representations of the 4D, $ {\cal N}$ = 1 spacetime supersymmetry algebra. Of necessity this includes a description of the mathematical mechanism by which four dimensional Lorentz symmetry appears as an emergent symmetry in the context of one dimensional adinkras with four colors described by the Coxeter Group $BC_4$.

description: There are three original contributions for the analysis of temporal data, such as pedestrian counts, airline traffic, and economic indicators. The first new technique is for visualising data using a calendar layout, to study daily human activity. The second contribution is a new data abstraction which streamlines transformation, visualisation, and modelling. This is a data pluming infrastructure. The third contribution is to equip analysts with exploratory and explanatory tools for understanding missing patterns in time, in preparation for modelling. Three software packages are provided for practical use.

Large PV Power Plants and High Penetration of Distributed PV: System Aspects and Grid Integration

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 5043-5045
description: T-Solar Global is the biggest PV electricity producer in Spain. At the end of 2008 T-Solar has an
installed power of 143 MW in 28 large ground mounted systems all over Spain. The module technology of these
plants is crystalline silicon from different suppliers. The majority of the systems are static devices and only 2.4 % of
the power is installed with trackers. The grid connected systems are permanently remote monitored in a centralized
control center located in Madrid. This monitoring provides a continuous follow up of the system performance and a
real time failure control. The operation results of the 28 systems during one full year will be presented. PV Trackers
will be compared with the results obtained on static systems of similar technology and location. Also the superior
behavior of an a-Si plant against c-Si plants is shown. T-Solar’s experience proves that ground mounted PV systems
can be efficiently planned and executed in a short time and demonstrates that additional investment on real time
monitoring systems can be recovered in a short period of time. The operation experience also provides clues for
further improvement of large ground mounted PV systems.

description: With our point of departure in the concept of cultural technology/technologies, the work of our research group strives first to gain an understanding of the conditions under which the description and representation of spatiality are possible within particular modalities of communication (geometric, algebraic, verbalized, as well as in drawings, models, and ›diagrams‹), and secondly, to analyze the role of the recording medium (in this case textuality) in these processes. Bearing in mind the focus of Research Group D-III the problematic of research group D-III (»Spatial Models and Spatial Thinking«) and that of Area D (»Theory and Science«) in the broadest terms, we seek on the basis of concrete case studies to describe the earliest instances of textuality, both the interdependence of materiality and object-form as well as the influence of textuality on the shaping and development of analytical thinking and the systematic acquisition of knowledge. The material focus is on documenting the cuneiform cultures of the Ancient Near East.
description: Ausgehend vom Begriff der Kulturtechnik(en) zielt die Arbeit der Forschergruppe darauf ab, einerseits ein Verständnis von den Bedingungen zu gewinnen, welche überhaupt die Beschreibung und Abbildung von Räumlichkeit in anderen medialen Zuständen (geometrisch, algebraisch, verbalisiert sowie als Zeichnung, Modell und ›Diagramm‹) ermöglichen, und andererseits die Rolle des fi xierenden Mediums (hier Schriftlichkeit) bei diesen Prozessen zu analysieren. Mit Blick auf die Fragestellung der Forschergruppe D-III (Spatial Models and Spatial Thinking) und im weiteren Sinne von Area D (Theory and Science) sollen an konkreten Fallstudien zur frühesten Schriftlichkeit sowohl die Interdependenz von Materialität und Gegenstand als auch die Einfl ussnahme der Schriftlichkeit auf die Ausprägung und Entwicklung des analytischen Denkens und der systematischen Erkenntnisgewinnung beschrieben werden. Den materialen Schwerpunkt bildet die Dokumentation der Keilschriftkulturen Altvorderasiens.

description: Reliable operation of PV plants requires suitable failure detection methods. Since no detection method
is perfect, there is always a tradeoff between the detection rate and the false alarm rate. A receiver operating
characteristic (ROC) analysis is useful to visualize this tradeoff and to compare the efficiency of different detection
methods.
Fast radio bursts as giant pulses from young rapidly rotating pulsars

description: We discuss possible association of fast radio bursts (FRBs) with supergiant pulses emitted by young pulsars (ages $\sim$ tens to hundreds of years) born with regular magnetic field but very short -- few milliseconds -- spin periods. FRBs are extra-Galactic events coming from distances $d \lesssim 100$ Mpc. Most of the dispersion measure (DM) comes from the material in the freshly ejected SNR shell; for a given burst the DM should decrease with time. FRBs are not expected to be seen below $\sim 300 $ MHz due to free-free absorption in the expanding ejecta. A supernova might have been detected years before the burst; FRBs are mostly associated with star forming galaxies. The model requires that some pulsars are born with very fast spins, of the order of few milliseconds. The observed distribution of spin-down powers $\dot{E}$ in young energetic pulsars is consistent with equal birth rate per decade of $\dot{E}$. Accepting this injection spectrum and scaling the intrinsic brightness of FRBs with $\dot{E}$, we predict the following properties of a large sample of FRBs: (i) the brightest observed events come from a broad distribution in distances; (ii) for repeating bursts brightness either remains nearly constant (if the spin-down time is longer than the age of the pulsar) or decreases with time otherwise; in the latter case DM $\propto \dot{E}$.

Sesleria orbelica var. pirinensis deyl (1946: 136)

description: Sesleria orbelica var. pirinensis Deyl (1946: 136)
 Lectotype (designated here):— BULGARIA. Blagoevgrad province: Pirin Mountain, ad oppidium Bansko [beside the town Bansko], Vallis [valley] „Banderica”, ca. [circa] 2200 m, solo granitico [only granite rocks], July 1936, I. Klášterský & M. Deyl s.n. (PR 161812!, Figure 8; isolectotype BP 593381!).
 Note:—Before giving the formal description, Deyl noted that there is a variety of S. orbelica growing on Pirin mt. in the Banderica valley, only on granite rocks (Deyl 1946). Although in the protologue he did not mention the type of bedrock, in his introductory remarks, which can be considered to be part of the protologue (Rec. 8A.4 footnote, McNeill et al. 2012), he mentioned “ Habitat in montibus Pirin Planina in Bulgaria ”. We found two specimens in PR identified as S. orbelica var. pirinensis by Deyl, and one duplicate of the specimen in BP. One of these specimens from PR had calcareous bedrock on the label, but the plants growing on limestone in Banderica valley were described as S. klastersky Deyl (1946: 144). The second specimen from PR, which clearly noted granite as the type of bedrock on which the plant was collected, is designated as lectotype, and the duplicate of this specimen in BP is an isolectotype.

description: With PV gaining significant shares of power generation, PV generation will sooner or later be
asked to submit production schedules to the power market. Moreover, in order to increase the hosting capacity of
local distribution grids, grid operators will require PV forecasts in order to anticipate bottlenecks and
corresponding mitigation actions as part of an active grid control strategy. The paper presents a rolling intra-day
forecast model that is well applicable to a single PV site. The model under development is based on a stochastic,
autoregressive time series model. It relies mainly on historical data which are received hourly from the
monitoring system of the PV installation. As the model does not rely on sophisticated downscaling from
numerical weather predictions, it is relatively inexpensive. The forecasting model was developed and verified by
means of several years of monitoring data from an existing PV installation. The root mean square error for this
forecast of output power was 6.7% of installed PV peak power. The model is currently applied in the field for
pilot forecasting for a smaller PV installation in order to match the demand of freezing equipment on the same
site. The objective is the creation of controllable electricity profiles over time.
