Do rainy or cloudy days affect solar panel energy production?

Yes, rain and clouds can affect solar panel energy production because they reduce the amount of sunlight that reaches the panels. When the sky is cloudy, the sunlight is diffused, which reduces the intensity of the light reaching the solar panels. Both weather conditions can cause a decrease in the amount of electricity the panels produce by as much as 25%-90%. However, this effect depends on the type and density of the clouds, but solar panels can produce electricity on partly cloudy days. Luckily, Nevada has more than 300 sunny days a year.

How many rainy and cloudy days in Southern Nevada?

Does rain affect your solar panels?

Our solar panel systems are designed to be weather-resistant and can continue to produce electricity even under cloudy or rainy conditions.

Does rain clean your solar panels?

Rain does help clean your solar panels, removing dust, debris, and bird droppings.

How does this affect your NV Energy Bill?

If you use more energy than your solar system produces, you may see a slight increase in your bill. If you have built Net Meter credits, the credits may be applied to your account to cover your consumption.
