Opis:: The work presents a method for hybrid connection of two systems used to obtain energy from solar radiation. The influence of temperature increase of the photovoltaic element on its efficiency was characterized. Two options for the construction of a system of the photovoltaic thermal type which are currently available for sale were presented. The advantages and disadvantages of connecting a collector installation with a photovoltaic installation were identified.

Opis:: In the study the authors introduced the idea of the operation of the photovoltaic system with possibly low temperature of photovoltaic cell surfaces. The attention was paid both to PV panels which are very popular in Poland and to currently less popular PV roofing tiles. The selected solutions were characterized, which - in the authors’ opinion - have a practical impact on lowering of the temperature of operation of photovoltaic cells, and thus increase the system’s energy yield. Special attention was paid to the concept of operation of the hybrid PVT collector as well as the selection of roof substrate for PV roofing tiles. Potential benefits resulting from conducted works were indicated for various groups of recipients. The results of first tests and calculations were also presented, which confirm the need of further research works on this issue.

Tytuł:: The effects of climate change on photovoltaic solar production in hot regions

Opis:: The work of solar cells and their production of electrical energy have been affected by climate change, especially in hot regions which became significantly hotter and still receive relatively high levels of solar radiation throughout the year. Higher ambient temperature and solar radiation result in higher PV cell temperature and, therefore, the reduction in PV module power output and efficiency. This study investigates how a PV module performs throughout the year in a hot region by considering the variations in cell temperature resulting from changes in ambient temperature and solar radiation every day. The tilt angles and two-axis tracking have also been examined. Results indicate that the two-axis solar tracking system is critical to use in hot regions for obtaining higher output power. Therefore, part of this power can be used to cool solar panels using various methods to keep their efficiency high, such as operating air fans or operating pumps to cool them with coolant.

Opis:: The aim of the paper was to show how cooling of silicone photovoltaic cells influences the amount of electrical energy they produce. The research was conducted both in the laboratory and under real outdoor conditions. Current-voltage characteristics for two different thermal states of PV cells were outlined. Obtained power values for a PV cell working under the influence of refrigerant and without such an influence were compared. As a result of mechanical cooling of PV cells, an increase in photovoltaic cell efficiency was proved.
Celem pracy było wykazanie, w jaki sposób chłodzenie krzemowych ogniw PV wpływa na ilość produkowanej przez nie energii elektrycznej. Badania przeprowadzono w warunkach laboratoryjnych i rzeczywistych. Opracowano charakterystyki prądowo-napięciowe dla różnych stanów termicznych ogniw PV. Porównano wartości pozyskiwanych mocy panelu fotowoltaicznego pracującego bez chłodzenia i z chłodzeniem. Wykazano wzrost wydajności, panelu fotowoltaicznego w wyniku mechanicznego chłodzenia ogniw PV.

Tytuł:: Experimental Study of Temperature Influence on the Performance of PV/T Cell under Jordan Climate Conditions
Autorzy:: Al-Odat, Mohammed Qassim
Powiązania:: https://bibliotekanauki.pl/articles/2202185.pdf
Data publikacji:: 2022
Wydawca:: Polskie Towarzystwo Inżynierii Ekologicznej
Tematy:: PV module
electrical conversion
electrical efficiency
water cooling
cooling
cell temperature
Opis:: The electrical performance and the productivity of PV module depend on two main parameters, i.e. the radiation intensity and the cell operating temperature. The module electrical efficiency and productivity are significantly reduced as its temperature increases. Accordingly, cooling of PV modules is one of the most effective techniques to obtain higher efficiency and productivity as well as to reduce the degradation modes of PV modules due to high temperatures. This research work presents an experimental study carried out to investigate the effect of PV module cooling on the performance of PV module under Irbid city (Jordan) climate conditions. It was found that the electrical efficiency and the productivity of the PV modules were approximately enhanced by 14%. Therefore, water cooling of the PV modules is essential to enhance their performance.
