“…In Uzbekistan, in particular, hot weather of more than 40 degrees in summer frequently occurs, which is known to reduce the efficiency of the module. Therefore, various modules and inverter technologies need to be verified in the Uzbekistan environment [5][6][7][8][9]. As part of these, an International Solar Energy Research Institute is conducting various demonstration experiments on a variety of products, including stand-alone, three-phase grid-connected, micro-inverter-type grid-connected, internal and foreign-made poly, and mono modules, and internal inverters.…”

The output energy characteristics of a 2.24 kW grid-connected micro-inverter type photovoltaic power generation system installed in Tashkent were studied using PVsyst software. In the best conditions, it operated for about 10 h a day and produced 14.65 kW h of power. Although PVsyst predicted 79.7%, the actual performance ratio (PR) was very high, at 95.5%. Analysis of the loss parameters revealed that the module's temperature influence was the most significant (-8.5%), followed by the inverter's switching loss (-5.7%).
