Abstract:
Outdoor performance characterisation of the Solar Photovoltaic (SPV) module is essential to while designing and commissioning a new SPV power plant. The health of SPV plant is monitored using a conventional method which underutilises the workforce and resources used for Operation and Maintenance (O&M) of the SPV power plant. Outdoor performance characterisation of SPV module using reliable, compact, portable, and economical Current-Voltage (I-V) curve tracer having IoT capability and auto sweep capability is presented in this paper. The capacitive load method is used for I-V curve sweep, and the result is compared with the resistive load method. In this paper, the advantages of using a capacitive load method over resistive load method are observed and experimentally validated. The ease of using IoT feature makes this proposed I-V Curve Tracer (IVCT) device more reliable to trace Current-Voltage (I-V) curve and Power-Voltage (P-V) curve for outdoor performance characterisation of SPV module.

Abstract This paper presents the design and the development of multi-string I-V curve tracer for photovoltaic (PV) strings. It uses a capacitive load and double pole relay to measure the I-V characteristics of a multiple PV strings simultaneously. The prototype is developed using a PIC18F4550 micro-controller and a graphical user interface GUI designed using Microsoft’s Visual Studio software. The I-V characteristics of the PV string are displayed on LCD (Liquid Crystal Display) and computer. The performance and functionality of the proposed I-V curve tracer have been tested using four PV strings. The experimental test shows that the proposed I-V tracer can measure and display the I-V characteristic of each PV string smoothly in the normal and shading conditions.

Abstract:
In recent years, solar photovoltaic energy is becoming very important in the generation of green electricity. Solar photovoltaic effect directly converts solar radiation into electricity. The output of the photovoltaic module MPV depends on several factors as solar irradiation and cell temperature. A curve tracer is a system used to acquire the PV current-voltage characteristics, in real time, in an efficient manner. The shape of the I-V curve gives useful information about the possible anomalies of a PV device. This paper describes an experimental system developed to measure the current–voltage curve of a MPV under real conditions. The measurement is performed in an automated way. This present paper presents the design, and the construction of I-V simple curve tracer for photovoltaic modules. This device is important for photovoltaic (PV) performance assessment for the measurement, extraction, elaboration and diagnose of entire current-voltage I-V curves for several photovoltaic modules. This system permits to sweep the entire I-V curve, in short time, with different climatic and loads conditions. An experimental test bench is described. This tracer is simple and the experimental results present good performance. Simulation and experimental tests have been carried out. Experimental results presented good performance.

Abstract:
An I-V curve measurement technique is one of the most important techniques available for characterising photovoltaic cells. Measuring an accurate I-V curve at the single-cell level is a challenging task because of the low voltages and high currents implied, requiring the management of very low impedances. In this paper, the authors propose a low-cost device for I-V curve measurements of single (or small amounts) of cells in a series based on the charge transfer between two capacitors of equal capacitance. Our measurement strategy allows us to trace the usual first quadrant curve (the normal working region of solar cells) as well as the second and fourth quadrants of the I-V curve, which are quite important for research purposes. A prototype was built to demonstrate the feasibility and successful measurements of the three-quadrant I-V curve, obtained for more than 20 different cells. To use the device in a laboratory, without depending on the solar irradiation, a modular platform was 3D-printed, integrating a board with infrared LEDs as irradiating devices, and housing (to place the solar cell under test). The result is a useful low-cost setup for three-quadrant I-V curve tracing that works as expected.

Abstract:
Photovoltaic (PV) energy is a renewable energy resource which is being widely integrated in intelligent power grids, smart grids, and microgrids. To characterize and monitor the behavior of PV modules, current-voltage (I-V) curves are essential. In this regard, Internet of Things (IoT) technologies provide versatile and powerful tools, constituting a modern trend in the design of sensing and data acquisition systems for I-V curve tracing. This paper presents a novel I-V curve tracer based on IoT open-source hardware and software. Namely, a Raspberry Pi microcomputer composes the hardware level, whilst the applied software comprises mariaDB, Python, and Grafana. All the tasks required for curve tracing are automated: load sweep, data acquisition, data storage, communications, and real-time visualization. Modern and legacy communication protocols are handled for seamless data exchange with a programmable logic controller and a programmable load. The development of the system is expounded, and experimental results are reported to prove the suitability and validity of the proposal. In particular, I-V curve tracing of a monocrystalline PV generator under real operating conditions is successfully conducted.

Abstract:
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior<br>The IxV curves tracers for PV modules are used as a method of diagnosis of problems such as shadowing, faulty connections and degradation conditions. There are several types and brands tracers commercially available, but their costs are quite high in the Brazilian market due to the need to import. This thesis describes the development and validation of a IxV curve tracer for PV modules based on the electronic load method using MOSFET as load to the module. By appropriate variation of the MOSFET gate-source voltage signal was possible to acquire the points of voltage and current of the PV modules terminals. These points were recorded using a data acquisition board with PIC18F2550, which is controlled by a computer via a USB with a graphical interface to the user. This interface was developed in MATLAB software ensuring greater flexibility and functionality to the device. For PV module temperature measurements PT100 sensors were used and measurements of solar irradiance was used a pyranometer LP02 model Hukseflux Thermal Sensor manufacturer, these sensors were connected to a supervisory system consists of a PC and a programmable logic controller (PLC). The validation process was conducted by comparing the electrical parameters provided by the developed tracer and the commercial tracer MINI-KLA. From this comparison an error was generated for each parameter. Three PV modules of different electrical characteristics (20 Wp, 87 Wp e 160 Wp) were used and there was similarity between the curves of the developed tracer with the curves of the commercial tracer. The average of errors of the electrical parameters for the 3 PV modules was less than 5% at no shading conditions. In two conditions of shading, the IxV curves provided by the two tracers for the KC 85 T PV module were compared and it was observed in the first situation that the MINI-KLA tracer could characterize only partially the curve while the tracer developed could characterize the curve fully, in the second situation there was great similarity between the curves of the two tracers with maximum percentage difference in the electrical parameters equal to 5.41%.<br>Os traÃadores de curva IxV para mÃdulos FV sÃo utilizados como um mÃtodo de diagnÃstico de problemas como sombreamento, conexÃes defeituosas e condiÃÃes de degradaÃÃo. Existem diversos tipos e marcas de traÃadores disponibilizados comercialmente, mas seus custos sÃo bastante elevados no mercado brasileiro devido à necessidade de importaÃÃo. A presente dissertaÃÃo aborda o desenvolvimento e a validaÃÃo de um traÃador de curva IxV para mÃdulos FV baseado no mÃtodo de carga eletrÃnica com uso de MOSFET como carga para o mÃdulo. AtravÃs da adequada variaÃÃo do sinal de tensÃo de gate-source do MOSFET foi possÃvel adquirir os pontos de tensÃo e corrente nos terminais dos mÃdulos FV. Estes pontos foram registrados atravÃs de uma placa de aquisiÃÃo de dados, com PIC18F2550, que à controlada via USB por um computador com uma interface grÃfica para usuÃrio. Esta interface foi desenvolvida com o software MATLAB, garantindo maior flexibilidade e funcionalidade ao dispositivo. Para mediÃÃes da temperatura do mÃdulo FV foram utilizados sensores PT100 e para as mediÃÃes de irradiÃncia solar foi utilizado um piranÃmetro modelo LP02 do fabricante Hukseflux Thermal Sensor; estes sensores foram utilizados atravÃs de um sistema supervisÃrio composto por um PC e um controlador lÃgico programÃvel (CLP). O processo de validaÃÃo foi realizado atravÃs da comparaÃÃo dos parÃmetros elÃtricos fornecidos pelo traÃador desenvolvido e pelo traÃador comercial MINI-KLA. A partir desta comparaÃÃo um erro foi gerado para cada parÃmetro. Foram utilizados 3 mÃdulos FV de diferentes caracterÃsticas elÃtricas (20 Wp, 87 Wp e 160 Wp) e observou-se proximidade entre as curvas do traÃador desenvolvido com as curvas do traÃador comercial. A mÃdia dos erros para os 3 mÃdulos relativa aos parÃmetros elÃtricos obtidos com os 2 traÃadores foi inferior a 5% em condiÃÃes sem sombreamento. Em duas condiÃÃes de sombreamento, as curvas IxV fornecidas pelos dois traÃadores relativas ao mÃdulo FV KC 85 T foram comparadas e observou-se na primeira situaÃÃo que o traÃador MINI-KLA conseguiu caracterizar apenas parcialmente a curva enquanto que o traÃador desenvolvido conseguiu caracterizar a curva totalmente, na segunda situaÃÃo observou-se grande proximidade entre as curvas dos dois traÃadores com diferenÃa percentual mÃxima nos parÃmetros elÃtricos igual a 5,41%.

Abstract:
O presente trabalho apresenta o desenvolvimento de um traçador de curvas I-V para aplicação em arranjos fotovoltaicos a serem medidos em campo. Este sistema utiliza a carga capacitiva como método de polarização do gerador fotovoltaico sendo o chaveamento realizado por transistores bipolares de porta isolada (IGBT). Para controle do chaveamento dos IGBTs e aquisição dos pontos I-V, a placa Arduino foi aplicada demostrando-se adequada para a proposta. Para tanto foi escrito, em uma variação da linguagem de programação C++, o programa de controle desta placa. Foram construídos circuitos auxiliares de amplificação de sinal para realizar as medidas de corrente e de irradiância, sendo nestes casos, usados como sensores um resistor shunt e uma célula de referência calibrada, respectivamente. Para medida da temperatura foi aplicado o sensor de temperatura LM35 que apresentou resultados satisfatórios. Os dados adquiridos pela placa Arduino são salvos em um cartão de memória para posterior análise. A análise de incertezas foi realizada usando métodos estatísticos, onde foram determinados os erros sistemáticos e aleatórios para cada canal de medição. O protótipo construído foi aplicado no levantamento da curva I-V de um gerador fotovoltaico composto de uma série de 3 módulos instalada no terraço do prédio que abriga o simulador solar do Laboratório de Energia Solar da Universidade Federal do Rio Grande do Sul (LABSOL) e o seu resultado foi comparado com o sistema traçador de curvas do laboratório. O resultado, de maneira geral, foi satisfatório quando comparado com a medida a 2 fios pelo sistema do LABSOL, mas apresentou um erro maior quando comparado à medida a 4 fios. Este protótipo também foi submetido a um teste para avaliar sua capacidade de apresentar a curva I-V de forma adequada quando são provocados defeitos na série de módulos. O resultado apresentado pelo protótipo se mostrou bastante semelhante ao do apresentado pelo sistema do LABSOL. De maneira geral, pode-se afirmar que o protótipo, baseado em seus resultados, mostrou-se adequado para aplicação em medidas em campo de curvas I-V de arranjos fotovoltaicos.<br>This work presents the development of an IV tracer for in field measurement of PV arrays. This system uses a capacitive load as a method for polarizing the photovoltaic generator, with the switching being performed by insulated gate bipolar transistors (IGBT). To control switching of the IGBTs and acquisition of the IV curve, an Arduino board was applied, and was proved to be adequate for this purpose. The Arduino board control program was written in a variation of C++ language. Auxiliary circuits for amplifying the signal were built to measure electric current and irradiance, being in such cases used as sensors a shunt resistor and a calibrated reference solar cell, respectively. For obtaining the temperature, the LM35 temperature sensor was employed, presenting satisfactory results. The data acquired by the Arduino board are saved on a memory stick for later analysis. The uncertainty analysis was performed by using statistical methods, in which the systematic and random errors for each measurement channel were determined. The assembled prototype was applied for measuring the IV curve of a photovoltaic generator composed of a string of 3 modules located on the roof of one of the buildings from Solar Energy Laboratory of the Federal University of Rio Grande do Sul (LABSOL) and its result was compared with the IV tracer used on the laboratory. The result was, generally, satisfactory when compared with the two-wire measurement by the laboratory’s system, but showed a larger error when compared with the four-wire measurement. This prototype was also submitted to a test to evaluate its capacity of adequately presenting the IV curve when defects are induced on the string. The result presented by the prototype was quite similar to that obtained from LABSOL’s system. In general, it is possible to affirm that the prototype, based on its results, proved to be adequate for in field measurement of photovoltaic arrays.

O presente trabalho consiste no desenvolvimento de um módulo electrónico de baixo custo, capaz de adquirir e traçar as curvas I-V (corrente versus tensão) de módulos fotovoltaicos, assim como medir outras grandezas utilizadas no diagnóstico de degradação, nomeadamente, tensão em circuito aberto, corrente de curto-circuito, radiação solar e temperatura. Numa primeira fase do trabalho decorrida no IPB, foram implementadas/testadas algumas montagens electrónicas com vista a verificar as possibilidades de implementação e validar a que melhor se coadunava para a implementação prática. De seguida, já no Ciemat, tomou-se conhecimento das distintas técnicas e procedimentos do Laboratório de Energia Solar Fotovoltaica para a realização de ensaios e medidas em módulos fotovoltaicos. Após a consolidação de conhecimentos, foi projectado, desenhado e construído um traçador de curvas I-V cumprindo os requisitos propostos, ou seja, de baixo custo e configuração simples. O módulo electrónico construído foi baseado na carga de um condensador de potência, uma carta de aquisição de dados e um comutador para duas opções de medida: módulos fotovoltaicos “convencionais” (10 A, 50 V) e módulos fotovoltaicos de lâmina delgada (2 A, 110 V). This work is based on the development of a low cost electronic module, able of acquiring and trace IV curves (current versus voltage) of photovoltaic modules, as well as measuring other quantities of the degradation diagnose, particularly open circuit voltage, current short circuit, radiation and temperature. On a former phase of this work, which took place at IPB, there were implemented/tested some electronic montages in order to verify the implementation possibilities and validate which suits better for the practical implementation. On a second phase, taking place at CIEMAT, there were acknowledged several techniques and procedures of the Photovoltaic Energy Laboratory for the execution of tests and measures on photovoltaic modules. After knowledge consolidation, it was projected, designed and built an IV tracer, according to the proposed requisites, as so, low cost and simple configuration. The electronic module built on his project, was based on the load of a power condenser, on data acquisition hardware and a two-measuring switch: conventional photovoltaic modules (10 A, 50 V), and thin-blade photovoltaic modules (2 A, 110 V).

Abstract:
abstract: In the current photovoltaic (PV) industry, the O&M (operations and maintenance) personnel in the field primarily utilize three approaches to identify the underperforming or defective modules in a string: i) EL (electroluminescence) imaging of all the modules in the string; ii) IR (infrared) thermal imaging of all the modules in the string; and, iii) current-voltage (I-V) curve tracing of all the modules in the string. In the first and second approaches, the EL images are used to detect the modules with broken cells, and the IR images are used to detect the modules with hotspot cells, respectively. These two methods may identify the modules with defective cells only semi-qualitatively, but not accurately and quantitatively. The third method, I-V curve tracing, is a quantitative method to identify the underperforming modules in a string, but it is an extremely time consuming, labor-intensive, and highly ambient conditions dependent method. Since the I-V curves of individual modules in a string are obtained by disconnecting them individually at different irradiance levels, module operating temperatures, angle of incidences (AOI) and air-masses/spectra, all these measured curves are required to be translated to a single reporting condition (SRC) of a single irradiance, single temperature, single AOI and single spectrum. These translations are not only time consuming but are also prone to inaccuracy due to inherent issues in the translation models. Therefore, the current challenges in using the traditional I-V tracers are related to: i) obtaining I-V curves simultaneously of all the modules and substrings in a string at a single irradiance, operating temperature, irradiance spectrum and angle of incidence due to changing weather parameters and sun positions during the measurements, ii) safety of field personnel when disconnecting and reconnecting of cables in high voltage systems (especially field aged connectors), and iii) enormous time and hardship for the test personnel in harsh outdoor climatic conditions. In this thesis work, a non-contact I-V (NCIV) curve tracing tool has been integrated and implemented to address the above mentioned three challenges of the traditional I-V tracers. This work compares I-V curves obtained using a traditional I-V curve tracer with the I-V curves obtained using a NCIV curve tracer for the string, substring and individual modules of crystalline silicon (c-Si) and cadmium telluride (CdTe) technologies. The NCIV curve tracer equipment used in this study was integrated using three commercially available components: non-contact voltmeters (NCV) with voltage probes to measure the voltages of substrings/modules in a string, a hall sensor to measure the string current and a DAS (data acquisition system) for simultaneous collection of the voltage data obtained from the NCVs and the current data obtained from the hall sensor. This study demonstrates the concept and accuracy of the NCIV curve tracer by comparing the I-V curves obtained using a traditional capacitor-based tracer and the NCIV curve tracer in a three-module string of c-Si modules and of CdTe modules under natural sunlight with uniform light conditions on all the modules in the string and with partially shading one or more of the modules in the string to simulate and quantitatively detect the underperforming module(s) in a string.<br>Dissertation/Thesis<br>Masters Thesis Engineering 2020

Abstract:
abstract: The goal of any solar photovoltaic (PV) system is to generate maximum energy throughout its lifetime. The parameters that can affect PV module power output include: solar irradiance, temperature, soil accumulation, shading, encapsulant browning, encapsulant delamination, series resistance increase due to solder bond degradation and corrosion and shunt resistance decrease due to potential induced degradation, etc. Several PV modules together in series makes up a string, and in a power plant there are a number of these strings in parallel which can be referred to as an array. Ideally, PV modules in a string should be identically matched to attain maximum power output from the entire string. Any underperforming module or mismatch among modules within a string can reduce the power output. The goal of this project is to quickly identify and quantitatively determine the underperforming module(s) in an operating string without the use of an I-V curve tracer, irradiance sensor or temperature sensor. This goal was achieved by utilizing Radiovoltmeters (RVM). In this project, it is demonstrated that the voltages at maximum power point (Vmax) of all the individual modules in a string can be simultaneously and quantitatively obtained using RVMs at a single irradiance, single module operating temperature, single spectrum and single angle of incidence. By combining these individual module voltages (Vmax) with the string current (Imax) using a Hall sensor, the power output of individual modules can be obtained, quickly and quantitatively.<br>Dissertation/Thesis<br>Masters Thesis Engineering 2019
