What is the weather condition where the sunflower photovoltaic power station has the highest power generation efficiency?

Spring and autumn. According to relevant public information, the power generation efficiency of photovoltaic power stations is the highest in spring and autumn. At this time, the temperature is suitable, the air clouds are thin, visibility is high, sunlight penetration is strong, and there is little rain. A photovoltaic power station refers to a photovoltaic power generation system that utilizes solar energy and uses special materials such as crystalline silicon panels, inverters and other electronic components. It is connected to the power grid and delivers power to the power grid.
