FAQ

Why doesn’t my solar panel reach its rated 160W?

When a solar panel is actually being used, it is normal that the actual power does not reach the rated power. Below are factors that will cause the power to be lower than the rated power and how to fix them.

The strength of the sunlight: The strength of the sun’s rays will cause the output power to fluctuate. While it may be relatively close to the tested conditions at noon on a clear day, it may be less in the morning or afternoon. Weather conditions will affect the light conditions, and hazy, cloudy, or rainy weather will cause the actual power to be much less than the rated power.

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

The angle of the sun’s rays: In good lighting, the solar panel can be perpendicular to the sunlight for better performance. A 10-degree difference between the light and the 90-degree angle of the panel has little effect on the power.

Interferences: When the solar panel is in use, try not to have anything covering the surface, including shadows, foreign objects, glass interferences, and even dust.

Faulty state: The product may be faulty if there is no power or the power is much less than the rated data if the above conditions are all satisfied. Contact after-sales for processing.
