“…Interesting discussion concerning the effect of external factors on working parameters of PV modules was conducted by the research group at AGH University of Science and Technology, Krakow, Poland. They've highlighted the issue of non-uniform temperature distribution, which means some solar cells heat up to higher values, thus impacting negatively energy yield of the whole installation [12]. Such outcome may be even more enhanced if the system has poor cooling conditions.…”

In the recent years photovoltaic (PV) industry has experienced a major growth, caused by the ever present annual decrease in module production prices and the expanding awareness of the general public in terms of renewable energy. There are numerous ways to implement PV modules as an additional energy source for a building, be it mounted on the rooftop, or building integrated (BIPV). An analysis of BIPV consisting of 8 modules with the power of 250 Wp each was carried out for the building of the Chemistry Faculty of Gdansk University of Technology (GUT). It included monthly irradiance and energy generation values and compared them to data obtained by the means of PV-GIS system, after inserting site specific coordinates. Additional research on the same type of a single module with the power of 270 Wp was conducted to provide more insight in this matter. A comprehensible analysis allows for defining a final conclusion for the decrease in energy yield for GUT BIPV installation. Data outputs are lower than expected based on PV-GIS values, as for the most time the facade mounted PV system experiences partial soft shading from the nearby park. Furthermore, it is not located directly facing south, but rather south-east which does not prompt ideal working conditions.

“…The real temperature of a module depends on the material properties of the used semiconductor, the quality and the hermetic configuration of the module and on the surrounding environment and the weather conditions. This is a result of physical phenomena occurring in an illuminated PV cell, associated with the process of the light absorption, generation and transport of charge carriers; their recombination and many processes occurring simultaneously in the environment of the module [17].…”

“…The most frequently used mathematical models that estimate the temperature of modules include only the irradiance and ambient temperature, but the latest research proves that, also, the parameters of the blowing wind contribute to the increase of the PV panels' efficiency. Increasing the heat dissipation intensity of the PV module influences its performance parameters [17]. Numerous authors, e.g., Skoplaki [18], Mattei [19], Faiman [20] and King [21], have undertaken intense work on new mathematical models, determining the average temperature of photovoltaic modules of micro-power plants, which include the effect of the blowing wind.…”

Sunlight is converted into electrical energy due to the photovoltaic effect in photovoltaic cells. Energy yield of photovoltaic systems depends on the solar array location, orientation, tilt, tracking and local weather conditions. In order to determine the amount of energy produced in a photovoltaic system, it is important to analyze the operation of the photovoltaic (PV) arrays in real operating conditions and take into account the impact of external factors such as irradiance, ambient temperature or the speed of blowing wind, which is the natural coolant of PV panels. The analysis was carried out based on mathematical models and actual measurement data, regarding the dependence of the average temperature of PV arrays on variable and difficult to predict ambient conditions. The analysis used standard (nominal operating cell temperature (NOCT)), King, Skoplaki, Faiman and Mattei thermal models and the standard model for flat-plate photovoltaic arrays. Photovoltaic installations PV1, PV2a and PV2b, being part of the hybrid power plant of the Bialystok University of Technology, Poland, were the objects of the research. In the case of a free-standing solar system, the Skoplaki model proved to be the best method for determining the average temperatures of the PV arrays. For building-integrated PV systems, a corrected value of the mounting coefficient in the Skoplaki model was proposed, and the original results were compared. The comparison of the accuracy measures of the average operating temperatures for three micro-power plants, differently mounted and located, is presented.

“…In large solar PV arrays, aging caused by environmental factors is a significant problem. The impact of environmental conditions on a solar PV system's power output has been widely investigated in other studies [4], [5]. Similarly, power output losses as a result of aging has also received significant study focus [6], [7], [8], [9].…”

There are several non-uniform effects on photovoltaic (PV) modules related to aging in a PV array. These subsequently bring about non-uniform operating parameters with individual PV modules, causing a variance in the PV array performance. The current study undertakes an indoor experimental study to establish and positively affect the efficacy of a non-uniform aged 2 × 4 PV array, with a commercially available small panel module of 0.36W (monocrystalline). This paper proposes a gene evolution algorithm (GEA) for offline reconfiguration that can provide more significant output power compared to nonuniformly aged PV arrays through repositioning instead of replacing aged PV modules, which will help lower maintenance expenses. This reconfiguration requires data input from the PV module's electrical properties in order to select ideal reconfiguration setups. The outcomes show that greater output power can be facilitated through a non-uniformly aged PV array and used on many different PV array sizes.
