FAQ:
Why do sometimes solar panels don't reach their rated 300W?
In reality, many external factors would affect the conversion efficiency, generating less power than the rated power, which is 300 watts. Here are the factors that most people might overlook:
1. The weak sunlight
When it’s cloudy or rainy, the solar radiation obviously decreases, the solar light is way less for the solar cells to generate the maximum power. To solar cells, the weaker the solar light or solar radiation they got, the smaller amount of the power they generate.
2. installation angle
In the same geographical location, the installation way will affect the conversion efficiency too. The longer time the solar panel bathed in the sun, the more power the solar panel generated. The best installation angle is around 30-40°, with the panel facing south.
