Problems solved by technology

[0002] Photovoltaic systems are used to collect solar energy and convert solar energy into electrical energy and store it. The essential components in the photovoltaic system are photovoltaic panels for collecting solar energy. Photovoltaic panels are also known as solar panels. Solar panels usually work The temperature is higher than room temperature, that is, 25 degrees. The higher the temperature, the lower the power generation efficiency. According to actual testing, the maximum conversion efficiency of solar panels is 20% at 25 degrees, and 18% at 45 degrees. Affects the power generation efficiency of photovoltaic systems
