FQA: Why is your solar panel not reaching 100W rated power?

When a solar panel is actually used, usually the actual capacity does not reach the rated capacity. Here are the factors that will cause the power supply to be below rated capacity and how to fix them.

A1: Sunlight intensity: Sunlight intensity will cause the output power to fluctuate. While it may be relatively close to the conditions tested at noon on a clear day, it could be less than in the morning or afternoon. Weather conditions will affect lighting conditions and cloudy, cloudy or rainy weather will cause the actual power to be much lower than the rated power.

A2: Surface temperature: The surface temperature of the solar panel will affect the solar panel's energy efficiency. The lower the surface temperature, the better the energy efficiency. For example, the capacity of solar panels in winter will be higher than in summer, which is normal. In summer, solar panels are exposed to light at temperatures close to 60°C; even if the light is better, the power will be 13% lower than the rated power.

A3: Angle of sunbeam: In good light condition, solar panels can be perpendicular to sunlight for better performance. The 10-degree difference between the light and the panel's 90-degree angle has little effect on the power supply.

A4: Obstacles: When using solar panels, try not to let anything cover the surface, including shadows, foreign objects, glass obstructions and even dust.
