PV Module Performance – Modelling, Testing, Standards

description: 8th World Conference on Photovoltaic Energy Conversion; 716-723
description: In this work a simulation model for a novel air-based BIPVT roof tile system with rear ventilation is presented. This work contributes to closing the research gap concerning the performance estimation of the electrical and thermal system of such BIPVT systems, also under real operating conditions. Therefore, a simulation model which enables a holistic evaluation of a BIPVT system energy yield and performance is set up and refined. To achieve this, the initial simulation model is adapted to state-of-the-art PV modelling and expanded by still required simulation approaches for system components not investigated yet. Additionally, besides the coupling of insights from previous research, influencing parameters are derived specifically for installed components on site. The calculation results for the installed test site indicate electrical system yields within the range of conventional PV systems and above average performance ratios. Due to the consideration of the solar cooling effect, an efficiency gain for the electric energy yield of 2.0 % is achieved. An increase of the annual performance of the heat pump of 6.0 % at best case is identified by using the solar roof tiles waste heat. In this context, a low mass flow rate of the base-fluid appears to be the operating condition leading to the highest benefits for the overall system yield. A model validation performed with the use of infield measurement data shows an overestimation of 1.3 % concerning the actual electrical yield. Overall, the final model predicts the electric power output before inverter losses with an accuracy of 4.7 % in relative RMSE. It can be concluded that the developed simulation model enables a realistic overall energy yield prediction for the novel BIPVT solar roof tile.

description: We consider an online learning to rank setting in which, at each round, an oblivious adversary generates a list of $m$ documents, pertaining to a query, and the learner produces scores to rank the documents. The adversary then generates a relevance vector and the learner updates its ranker according to the feedback received. We consider the setting where the feedback is restricted to be the relevance levels of only the top $k$ documents in the ranked list for $k \ll m$. However, the performance of learner is judged based on the unrevealed full relevance vectors, using an appropriate learning to rank loss function. We develop efficient algorithms for well known losses in the pointwise, pairwise and listwise families. We also prove that no online algorithm can have sublinear regret, with top-1 feedback, for any loss that is calibrated with respect to NDCG. We apply our algorithms on benchmark datasets demonstrating efficient online learning of a ranking function from highly restricted feedback.

PV Module Performance – Modelling, Testing, Standards

description: 8th World Conference on Photovoltaic Energy Conversion; 704-707
description: Modeling and simulation of a PV cell or module are crucial for diagnosing the cell defects and degradations, estimating resulted losses, and predicting cell or module performance at desired environmental conditions. PV cell is generally modeled using a single diode model (SDM) or double diode model (DDM). For the simulation of these models, accurate cell parameters extraction from an I-V characteristic is essential. Various methods have been reported in the literature to estimate cell parameters; however, most of them discuss parametric extraction of defect free PV cell. Also, most of the existing parametric estimation algorithms offer high accuracy on the cost of complexity and heavy computational burden. In this work, the simplified parametric extraction method is proposed based on the step-by-step division of I-V curve. Analysis of seven PV cell parameters and their region of dominance in I-V curve is studied. Based on that, step by step cell parameters extracted dividing I-V curve in the range of [0, open circuit voltage (Voc)]. This method is verified on healthy and defective cells such as potential-induced degradation (PID) affected and cracked solar cells. Results show that I-V curve reproduced by cell simulation based on the extracted cell parameters shows a good agreement with the experimental IV curve with root mean square error < 0.2. The proposed method can effectively estimate seven parameters of a PV cell at any stage of degradation with reduced complexities and computational burden.

description: A new approach is presented to determine the angular response of PV modules outdoor, using a dual axis solar tracker and a reference module with known angular response. The method is based on measuring Isc data for both sample and reference module, rotating both modules away from the sun to vary the angle of incidence from 0-90 °. From these data, the Incident Angle Modifier (IAM) curve is calculated. Thanks to the quick rotation (< 1 min), no temperature sensors are needed. For outdoor calibration of reference (mini-)modules, a 1.2 m long tube is used, in which the reference module is rotated while the tube is tracking the sun. In this way, the IAM curve can be determined without diffuse light disturbance. Using such a reference module, IAM curves were determined for several modules. In particular, a mini-module previously measured indoor at PI-Berlin was measured, the maximum difference between the two curves was 1.1%. Compared to the outdoor IAM measurement of PV modules in IEC 61853-2, the method above requires less equipment/sensors and is faster. The method is also accurate, the use of a reference module and the calculation method ensure correction for the varying diffuse irradiation across the sky.

description: With the reported downward spiral of engagement levels worldwide, and many Research indicating that employees are no longer satisfied with traditional reward systems, organizations are becoming aware that in order to deal with this, attract best talent and keep them engaged, they need to shift their attention to total reward strategies. The main purpose of this study was to explore the relationship between total rewards and work engagement in Ethiopian context and to determine which reward categories significantly predict employee engagement. The study further endeavored to determine whether perceived reward fairness had a moderating effect on the relationship between total rewards and employee engagement. A quantitative, cross-sectional research design was adopted. By dividing the total population in to strata and then by using a non-probability convenience and purposive sampling strategy, 315 questionnaires were collected and analyzed from two randomly selected private banks in Addis Ababa. The 17-item UWES, WorldatWork total reward model and 18 item questioner to test perception of fairness developed by Moorman (1990) were chosen as measuring instruments. Evidence from the study suggested that three total reward dimensions explained 37.5% of the variance in employee engagement. From the study it was found that Intrinsic rewards had the biggest significant effect on employee engagement. Similarly, Work life balance also had a significant effect on employee engagement .unlike the two Extrinsic rewards was found to negatively affect employee engagement. In addition, results from the study inferred that perceived fairness moderated the relationship between total rewards and employee engagement. Evidences from the study suggested that Total Rewards and perception of fairness are important engagement factors for employees in the workplace. unlike the other two subscales, Extrinsic rewards had negatively affected employee engagement implying that more research is needed and Organizations seeking to implement total reward strategies should pay attention to which reward categories have a positive impact on employee engagement.

description: Automated source extraction and parameterization represents a crucial challenge for the next-generation radio interferometer surveys, such as those performed with the Square Kilometre Array (SKA) and its precursors. In this paper we present a new algorithm, dubbed CAESAR (Compact And Extended Source Automated Recognition), to detect and parametrize extended sources in radio interferometric maps. It is based on a pre-filtering stage, allowing image denoising, compact source suppression and enhancement of diffuse emission, followed by an adaptive superpixel clustering stage for final source segmentation. A parameterization stage provides source flux information and a wide range of morphology estimators for post-processing analysis. We developed CAESAR in a modular software library, including also different methods for local background estimation and image filtering, along with alternative algorithms for both compact and diffuse source extraction. The method was applied to real radio continuum data collected at the Australian Telescope Compact Array (ATCA) within the SCORPIO project, a pathfinder of the ASKAP-EMU survey. The source reconstruction capabilities were studied over different test fields in the presence of compact sources, imaging artefacts and diffuse emission from the Galactic plane and compared with existing algorithms. When compared to a human-driven analysis, the designed algorithm was found capable of detecting known target sources and regions of diffuse emission, outperforming alternative approaches over the considered fields.

description: Fundamental properties of warm dense matter are described by the dielectric function, which gives access to the frequency-dependent electrical conductivity, absorption, emission and scattering of radiation, charged particles stopping and further macroscopic properties. Different approaches to the dielectric function and the related dynamical collision frequency are compared in a wide frequency range. The high-frequency limit describing inverse bremsstrahlung and the low-frequency limit of the dc conductivity are considered. Sum rules and Kramers-Kronig relation are checked for the generalized linear response theory and the standard approach following kinetic theory. The results are discussed in application to aluminum, xenon and argon plasmas.

description: Impaired cerebral vasoregulation is one of the most common post-ischemic stroke effects. Diagnosis and prevention of this condition is often invasive, costly and in-effective. This impairment restricts the cerebral blood vessels to properly regulate blood flow, which is very important for normal brain functioning. Developing accurate, non-invasive and efficient methods to detect this condition aids in better stroke diagnosis and prevention. The aim of this thesis is to develop deep learning techniques for the purpose of detection of cerebral vasoregulation impairments by analyzing physiological signals. This research employs various Deep learning techniques like Convolution Neural Networks (CNN), MobileNet, and Long-Short-Term Memory (LSTM) to determine variety of physiological signals from the PhysioNet database like Electrocardio-gram (ECG), Transcranial Doppler (TCD), Electromyogram (EMG), and Blood Pressure(BP) as stroke or non-stroke subjects. The effectiveness of these algorithms is demonstrated by a classification accuracy of 90\% for the combination of ECG and EMG signals. Furthermore, this research explores the importance of analyzing dynamic physiological activities in determining the impairment. The dynamic activities include Sit-stand, Sit-stand-balance, Head-up-tilt, and Walk dataset from the PhysioNet website. CNN and MobileNetV3 are employed in classification purposes of these signals, attempting to identify cerebral health. The accuracy of the model and robustness of these methods is greatly enhanced when multiple signals are integrated. Overall, this study highlights the potential of deep multimodal physiological learning in the development of precision brain medicine further enhancing stroke diagnosis. The results pave the way for the development of advanced diagnostic tools to determine cerebral health.

description: For the accurate evaluations of energy rating, the electrical performance parameters obtained at STC need to be transferred to real conditions by the use of well determined linear equations defined in IEC 61829 standard. One of the most important requirements for this is the determination of the linearity of electrical performance parameters of PV modules at various irradiance levels. In this work, the linearity measurements of a mono-crystalline, a polycrystalline, a CIGS thin film and a bifacial PV module were investigated using a xenon light based solar simulator system with irradiance attenuating filters. To measure the linearity of PV modules accurately a comprehensive analysis of all factors that may affect the linearity were done. In this context, initially the solar simulator was optically characterized according to the IEC 60904-9 standard requirements in terms of spectral match, spatial non-uniformity and temporal instability. Next, an effect of irradiance attenuating filters on non-uniformities of simulator was determined. Then, PV modules were electrically stabilized to remove any fluctuations in their electrical performance parameters. Finally, the electrical performance parameters of PV modules were measured at a range of irradiance levels from 100 W∙m-2 to 1000 W∙m-2 and their linearity were determined using the least-squares fit method.

description: This work proposes a novel calculus method that goes deeper into the nature of photovoltaic technology. For this purpose, a distributed solar cell model is used to calculate the IV curves of a solar module. The main advance of this approach is that the user can set the topology of the solar module, as well as each parameter of the solar cells that compose it. Also, the proposed calculus method offers the possibility of modifying the protection system model, adding another degree of freedom to the original problem. Finally, similarly to PVmismatch, the proposed method is able to calculate IV curves given the irradiance and cell temperature of each solar cell.

PV Module Performance – Modelling, Testing, Standards

description: 8th World Conference on Photovoltaic Energy Conversion; 691-694
description: In the current work we study the performance of three photovoltaic (PV) cell technologies under real operating conditions and five years of observations. The measurements are in Saudi Arabia, a challenging place for solar panels' performance as they often operate at temperatures far beyond the Standard Test Conditions (STC). We perform statistical comparisons between the three solar cell technologies (Back-Contact, Hetero-Junction, and Aluminum Back Surface Field) and estimate each PV cell's efficiency. Towards this purpose, we employ statistical and machine learning tools. We use two approaches for cell technology comparisons. The first is non-parametric and depends only on the energy yield output. The second approach is parametric, and a linear model between the energy yield and the irradiance is learned, with stationary and time-varying coefficients. The energy output differences between the cell technologies were small but statistically significant. We conclude that the highest average power output is given by the BC technology, followed by the HJT and the AlBSF technologies. Additionally, we quantify the deterioration of the cell performance over time and the variations due to seasonal factors.

description: We present a strong-coupling approach to the theory of high-temperature superconductivity based on the observation of a quantum critical point in the plaquette within the t,t' Hubbard model. The crossing of ground state energies in the N=2,3,4 sectors occurs for parameters close to the optimal doping. The theory predicts the maximum of the d(x2-y2)-wave order parameter at the border between localized and itinerant electron behavior and gives a natural explanation for the pseudo-gap formation via soft-fermion mode related to local singlet states of the plaquette in the environment. Our approach follows the general line of resonating valence bond theory stressing a crucial role of singlets in the physics of high-Tc superconductors, but focuses on the formation of local singlets, similar to phenomena observed in frustrated one-dimensional quantum spin models.

description: The government of Ethiopia has launched economic reforms, financial liberalization measures and restructuring of financial institutions with the aim of promoting a competitive environment and efficient banking services to the public. The major objective of this study is assessing the effect of service quality gap on customer satisfaction in five branches found under Dashen bank. To attain this objective, questionnaires was designed and categorized under five dimensions of the SERVEQUAL model. The sample consists of 390 respondents selected based on convenience sampling procedure from the selected branches. This study used quantitative research design and both primary and secondary data. The collected data"s was analyzed with the help of SPSS version 23.Mean gap score of expectation and perception were used to investigate the relationship between dependent and independent variables. The correlation results indicate that there is a positive correlation between the service quality gap dimensions and customer satisfaction. The finding of the analysis showed that, the performance of Dashen bank in providing quality service is not in a position to meet the expectation of the customer. Low service quality leads low customer satisfaction. Based on this, in order to improve performance of the bank, the researcher suggested that, the bank should prepare complaint-handling mechanisms, relevant and timely training for its front line employees and make service quality gap analysis on fixed time framework.

description: EDF R&D has developed its in-house 3D PV modelling tool PVNOV®. It is using reverse raytracing for a more efficient calculation of irradiance on the cells/modules of PV plant. The energy yield is calculated in the aftermath of the irradiance estimation through an improved single-diode model and an advanced thermal model. The thermal model considers the thermal inertia of the module, as well as the convective and radiative heat exchange with environment. This model is challenged and recalibrated based on experimental data for several module technologies and various setups that are presented in this work: monofacial and bifacial modules, full-cell and half-cell modules, glass-glass or glass-backsheet modules, in addition to less-common white ceramics glass-glass modules. The indoor and outdoor thermal measurements are performed using several temperature probes on the back of the module and the open-circuit voltage according to the method described in the IEC 60904-5:2011 standard adapted to bifacial modules. A comparison of the thermal model performance with 2-years measurements from an instrumented testbed in an EDF’s outdoor test zone is finally introduced.

description: This article addresses the problematic of having a cost-effective material quality control for photovoltaic modules with a focus on backsheet. A low cost near infrared (NIR) spectroscopic equipment is used to determine the backsheet type present on modules with unknown material. An initial calibration is carried out using RAMAN spectroscopy to associate NIR spectra signature with five different backsheet types. RAMAN equipment allows to identify the global backsheet composition, but some uncertainties can remain linked to modified backsheet composition with similar spectrum form. The depth of analysis is also limited: the external and core layers are accessible, but the inner layer remains almost out of range. Therefore, we can’t always be completely sure of the exact backsheet composition. Destructive analysis using physical or chemical identification may be required to detect all elements unambiguously if needed. After this calibration, the NIR equipment was able to identify the main backsheet types from eight out of ten modules with unknown backsheet in a few seconds. The two remaining have a high gloss which seems to have disrupted the signal giving non reproducible spectra. Also, it has to be noted that some infrared signatures seem to be sufficiently unique to detect unambiguously the core and outer layer composition (polyamide in AAA backsheet in particular) but some other ones have very similar spectrum and the device may not be always able to identify them correctly (PVDF/PET/PVDF (“KPK”) backsheets in particular with EVA/PET/PET (“PPE”)). More module types are needed to validate the method robustness but the already obtained results are quite impressive regarding the simplicity of such a tool. In addition, the NIR spectrometer software allows to share the reference infrared spectra to other users. This can be used on existing and new power plants to test module’s backsheet type with the same references. Further works on NIR measurements using other backsheet types or dirty and aged modules will also be carried out to validate the possibility of using these devices on modules from the field or aged artificially. Testing is also in progress on the module junction box composition and the silicon glue used for fixing it to the rear side.

description: We explore a novel method to potentially very accurately estimate the temperature coefficient (TC) of ß a PV module’s Open-circuit voltage VOC in outdoor characterization. The goal is to improve the accuracy of the classical methods for outdoor evaluation which can have significant uncertainties, causing a less accurate Equivalent Cell Temperature (ECT) evaluation. The ‘RMSE method’ is based on sensitivity analysis of ECT with respect to the error in the used ß value. The difference between the calculated ECT and measured Tback is plotted over the effective in-plane irradiance, resulting in a AT scatter plot. Our decomposition of AT(ß’) very accurately describes how the AT plot changes with an erroneous value ß’. We refute the initial hypothesis, namely, the ß’=ßR corresponding to minimal scatter is not the true ß (but for most c-Si PV, ßR and the classic value ßo differ within a few %). Our accurate RMSE fitting for c-Si and thin-film PV suggests correct mathematical modeling but the corresponding scatter term in the decomposition is independent on the true ß. The ‘linear’ and ‘vertical-axis intercept’ terms can be investigated in future works. The ECT evaluation procedure has also been adapted to bifacial (BiFi) c-Si PV modules in earlier works, and therefore the present line of research is also applicable to that technology.
title: The Spatial Distribution of General Medical Practitioners
Creators: name: Butler, J. R.
Publisher: name: University of Kent
Year: 2022

description: Most governments regard the spatial distribution of physicians as sub-optimal, whatever methods of remuneration or health care delivery are used. Explanations of the spatial patterning of medical manpower have invoked economic, sociological and epidemiological concepts, although no satisfactorily unifying theories have been found in the literature. Attempts by governments to influence the distribution of physicians have varied in content; many policies have embodied some form of control or incentive, but others have sought to enhance the natural factors that are believed to attract physicians to undermanned localities. Post-war policies in the National Health Service for the spatial distribution of general medical practitioners have emphasised the elements of financial incentive and negative control, yet the trends in distribution since 1948 have been fluctuating rather than linearly progressive. The perceived inequity of existing distributional patterns remains a matter of contemporary concern, and the geographical mobility of general practitioners (to the extent that this is known from routinely available statistics) appears to be dysfunctional to a desirable distribution. Analysis of the objectives and contents of the policies reveals a number of conceptual problems and administrative inadequacies. The most important conceptual problems concern the equity objectives of existing distributional policies, the choice of territorial units in the assessment and control of locational choices, the adequacy of the statistical measures that are traditionally employed as indicators of maldistribution, and the potential ambiguities arising from a failure to distinguish between the adequacy of the aggregate supply of manpower and its distribution. The administrative inadequacies include a disincentive effect inherent in the regulations governing the payment of financial incentives and the inability of routine data sources to permit an on-going surveillance of relevant trends.

description: Current more novel interconnection methods for Si solar cells such as shingling, multi-wire, conductive backsheet, and multi-ribbon approaches, are structurally more complex than conventional 2-5 busbar stringing. The most common techniques used for the development of these concepts are electrical characterization (current-voltage measurements and electroluminescence imaging) in combination with a cross-section analysis using SEM and EDX. Other characterization methods, such as scanning acoustic microscopy (SAM) are implemented, especially to search for voids and delamination within the module. Using micro-computed tomography (μCT) is reported as a viable method to inspect new module concepts in the past, however, very few effective results are published. Current state-of-the-art μCT devices are capable to achieve a lower voxel size and higher resolution on larger samples than ever before. In this work, the multi-ribbon interconnection for back-contact cells under development at imec is being used as a case study to investigate the potential of these new μCT devices for PV research. A 20 x 20 cm2 one-cell module is electrically characterized before, during and after reliability tests in the form of thermal cycling and humidity-freeze cycling. The results show an unstable shunt being present in the module. Before and after the reliability tests, a TESCAN UniTOM XL scanner is used to scan the one-cell module using μCT. Due to a large amount of metal in the module, artifacts such as photon scattering and shadowing in the region around the ribbons were observed. The use of binning and different metal filters was tested as a way to decrease these artifacts. Using a 1 mm tin filter in combination with binning seems to achieve the best results when scanning (part of) a PV module.

description: Mobilization of deposits is one of the important functions of banking business and it is an important source of working fund for the bank. On the other hand, performance of banking industry may be gauged through value of deposit and loan. The aim of this research is to investigate the impact of deposit mobilization and loan disbursement on Bank's financial performance using seven years data from the year 2010 to 2016 with a sample of thirteen Ethiopian commercial banks. The relevant literature was reviewed for the purposes of this study. Explanatory research design was used in trying to establish the causal effect relationship between the independent variables (amount of mobilized deposit, amount of disbursed loan and none performing loan) including the control variable (bank size) and the dependent variable (Return on Asset). To get information about the selected variables secondary data was collected from the NBE. The study utilized both correlation and panel data with multiple regression method as data analysis in drawing conclusions about the study. The findings of the study shows that amount of mobilized deposit, amount of disbursed loan and bank size had positive and significant impact on the performance of Ethiopian commercial banks. On the other hand, none performing loan had a negative and insignificant impact on banks performance. Based on the findings and conclusion the recommends that banks should attract depositors and deposit by providing convenience accessible banking (through expanding number of branches, introduce and enhance E-banking such as internet banking, card banking and mobile banking), quality service( Improving employees knowledge and skills on banking product and customer service)

description: Inherent in any organization are security risks and barriers that must be understood, analyzed, and minimized in order to prepare for and perpetuate future growth and return on investment within the business. Likewise, company leaders must determine the security health of the organization and routinely review the potential threats that are ever changing in this new global economy. Once these risks are outlined, the cost and potential damage must be weighed before action is implemented. This paper will address the modern problems of securing information technology (IT) of a mechanical engineering enterprise, which can be applied to other modern industries.

description: The Method uses HEK293TrexR4 cells (=wt) cells and genetically engineered variants (wt OE, KD, other) to provide a basis for expression analysis and to detect the localization of SLC-HA-Strep- tag in cellular compartments. This protocol describes the physical preparation of microscopic samples. Image analysis with respect to compartmental co-localization of the SLCs respectively their detection tags will be covered separately. Therefore, we describe how an HA Tag is co-stained with Hoechst 33342 and specific compartment markers for Golgi, Lysosomes, ER, Mitochondria, Cell Membrane, Peroxisomes, Endosomes and Cytoplasm in order to either measure the total intensity of expressed SLC-HA tag protein per cell or give estimates on their cellular distribution. We chose a 60x magnification using water immersion objectives and a well bottom with 192um COC film thickness to provide high quality images. For compatibility reasons also 20x images are recorded using HCS cell mask stains as a backdrop to find cytoplasmic outlines.

PV Module Performance – Modelling, Testing, Standards

description: 8th World Conference on Photovoltaic Energy Conversion; 666-669
description: The aim of this work is to demonstrate a photovoltaic performance loss analysis workflow for a rooftop system installed in Nordic climate. There is a variety of methods for evaluating the performance loss of a PV system, but they give different results, making comparisons between studies challenging. This study uses several combinations of filters and statistical methods to calculate the performance loss rate, giving values between 1.5 and 3.6 %/year. The range of values is large and steps should be taken to minimise the variance and reach a value that can be compared with other studies. One method to reduce variance in the calculated performance loss rate is to improve data quality, and thus reduce the impact the data filters will have on the analysis. Data quality can be improved by taking great care in the design of the measurement setup and by monitoring the data quality as the measurement is ongoing. Comparability can also be improved during the data analysis by performing it with multiple methods and data filters, as in this work, thus generating a distribution of performance loss rates that can be handled with statistical methods or compared individually with other studies using similar methods.
Supraposinormality and hyponormality for the generalized Cesàro matrices of order two

description: It is well known that the generalized Cesàro matrices of order one are hyponormal operators on $\ell^2$, and it has recently been shown that the Cesàro matrix of order two is also hyponormal. Here the relatively new concept of supraposinormality is used to show that the generalized Cesàro matrices of order two are both posinormal and coposinormal, and that "most" of them are also hyponormal. A conjecture is propounded that would extend the hyponormality result.

PV Module Performance – Modelling, Testing, Standards

description: 8th World Conference on Photovoltaic Energy Conversion; 670-673
description: The science and engineering of soiling of solar devices is now well into its eighth decade, with more than 400 research papers this past year. The interests are technologically diverse, ranging from performance monitoring to mitigation methodologies. The derating of the energy output from a PV installation is a concern for both technology reliability and operating costs. This paper examines aspects of the relationships between the soiling of PV modules and the effects of this environmental process on the resulting performance and temperature characteristics. Thin-film CdTe and crystalline-Si modules are evaluated and compared for both uniform and non-uniform soiling patterns. The comprehensive studies document and compare laboratory simulations with actual outdoor cases for framed and frameless module structures. There is some emphasis on edge-buildup patterns, which are among the most common non-uniform deposition configurations, for both portrait and landscape module orientations. These non-uniform accumulations not only cause decrease in the produced power- output but result in shading that can cause increased confine areal heating (“hot spots”) that can lead to module degradation. This paper further documents effects of both uniform and non-uniform soiling patterns on the J-V characteristics, documenting changes in the shape of these characteristics with the geometry and thickness distributions on the module surfaces. The special focus is to evaluate the specific effects of the non-uniform distribution on module temperature distributions using IR thermography and complementary techniques. These soiling patterns, performance parameters, and temperature distributions/levels are determined for modules in several Brazil climate zones. Temperature differences can exceed 40°C in excess normal operating temperatures for cells due to non-uniform soiling for the crystalline-Si cases; and corner soiling can lead to hot-spot formation no matter the module orientation.
