“…In the case of PV installation at GUT in Gdansk the front part is adequately chilled by wind, however the backside is closely moved against the building facade and most likely faces restricted heat flow. The negative impact of high temperatures has been linked to an overall PV module efficiency [13]. The flow of both functions, for irradiation and energy generation, is similar.…”

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.

“…While the voltage drops noticeably with temperature increase, the generated current only increases slightly. The power of the photovoltaic module is expressed as the product of instantaneous current and voltage values of the generated electric current, whereby the voltage parameter has a much more significant meaning [5]. Therefore, it is important to take into consideration changes in ambient temperatures during their operation when photovoltaic installations are designed.…”

The article presents the results of research on the efficiency of photovoltaic modules cooled by water. The purpose of the experiment was to improve the working conditions of the solar cells. Lowering the cell temperature increases the power generated by the device. The decrease in the temperature of the PV module was obtained by pouring water on the upper surface of the cells, as rain imitation or a water film. The power of the cooled and non-cooled devices were compared. The best results were achieved by cooling cells with a water film since there were no water splashes. The continuous cooling of cells surface causes a 20% increase of device's power. During the test, the non-cooled module reached the maximum power of 172 W, while the cooled one -205 W. Cooling the module resulted in an increase in power by 33 W. In addition, the temperature of the cells dropped to almost 25°C. At this time, the temperature of the non-cooled module was 45 °C. The presented solution may be an interesting proposition for small installations. The solution can also be an alternative for cleaning the modules due to the improvement in the power of the module after the test in terms of their power before.

“…One of the reasons is that photovoltaic cell technology is constantly evolving. In the following papers it has been proved that the efficiency of photovoltaic systems depends on the location [24][25] [26], weather [27] and angles of surface orientation in relation to the horizon and azimuth [28][29] [30]. The objective of this paper is to add to this area of study with an analysis of the CdTe and CIGS modules fabricated by thin film technology working in the temperate climate.…”

There is a significant amount of research in the literature concerning the performance of solar panels operating during outdoor exposure, but the full topic is not yet exhausted. One of the reasons is that the photovoltaic cell technology is constantly evolving. In this paper, a comparison of two types of CdTe and CIGS modules operated with a nominal power of 80 W and 140 W, respectively is studied. The module tests were performed under external conditions during autumn, winter, spring, and summer from October 2019 to July 2020 in the temperate climate of Miękinia, South Poland. The photovoltaic panels were connected to the electric grid via microinverters. During the tests, the temperature of the panels was monitored. To determine the influence of solar radiation on the energy conversion efficiency of photovoltaic panels, a pyranometer installed in the plane of the panels was used. Based on the monitoring of the atmospheric conditions and the measurement of instantaneous power, the efficiency of the modules is determined.
