There are many factors that affect the power generation of photovoltaic modules. The following are some main factors:
1. Intensity of solar radiation: The intensity of solar radiation is one of the determinants of the power generation of photovoltaic modules. The greater the intensity of solar radiation, the higher the power generation of photovoltaic modules.
2. Temperature: The power generation efficiency of photovoltaic modules will decrease at high temperatures. Therefore, temperature has a great influence on the power generation of photovoltaic modules.
3. The area and quality of photovoltaic modules: photovoltaic modules with larger areas can collect more solar energy, resulting in higher power generation. In addition, high-quality photovoltaic modules have higher efficiency and longer service life, which can improve power generation.
4. Angle of photovoltaic modules: The installation angle of photovoltaic modules will also affect its power generation. The ideal installation angle should be perpendicular to the sunlight, but actually it varies due to regions, seasons, weather and other reasons.
5. Pollution and shelter: If there is dust or other pollutants on the surface of photovoltaic modules, it will reduce its power generation efficiency. Similarly, if there are occluders around to block the sunlight and cause impact, it will also affect the power generation of photovoltaic modules.
To sum up, there are many factors that affect the power generation of photovoltaic modules. To obtain more benefits, we must choose high-quality photovoltaic modules, choose the right angle during installation, remove the obstructions in time after installation, and clean the modules regularly.
