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%).
