Experimental studies of the monocrystal and polycrystal characteristics of silicon photovoltaic modules under environmental conditions of Tashkent

Abstract

Studies of monocrystalline and polycrystalline silicon photovoltaic modules under environmental conditions of Tashkent were carried out. A decrease in the power of mono-PVM and poly-PVM was revealed, which in the summer period was 30 and 28% respectively. It was shown that, under otherwise equal conditions, the average temperature T t of the poly-PVM appeared to be 2°C lower than T t of the mono-PVM. In this case, both PVM types had average efficiency values of ~13.3%. It was found that the productivity factor of the studied poly-PVM and mono-PVM under environmental conditions of Tashkent was 0.75 and 0.77, respectively.
