FAQ:
●Why doesn’t my solar panel reach its rated 300W?
When a solar panel is actually being used, it is normal that the actual power does not
reach the rated power. Below are main factors that will cause the power to fall below
the rated power.
Sunlight Intensity: 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 Angle of the Sun's Rays: In good lighting angle, the solar panel can be

12
perpendicular to the sunlight for better performance.
Interferences: When the solar panel is in use, try NOT to have anything covering
the surface, including shadows, foreign objects, glass windows, and even dust.
If the above conditions are met, no power or the power much less than the rated
power, the product may be faulty. Please feel free to contact ELECAENTA and our
global customer service team will do their best to make you completely satisfied.
