Do Solar Panels Produce on Cloudy Days

Yes, solar panels produce even when the sun isn’t directly shining on them. From the moment of sunrise to the moment of sunset, the photo-reactive elements of the solar panels are producing energy.

If the sun is shining bright, of course then panels are producing at maximum efficiency. Any diminishment in the direct sunlight will affect the panels in direct proportion to how much light is blocked by clouds and precipitation.

Your solar system from EcoMark Solar will be designed using the weather averages for your area to help predict and warranty your panel’s production. Colorado is known for having over 300 days of sunshine, but it should have somewhere around 360+ days of solar energy production because rarely, in Colorado is there a zero production day.

Watching your SolarEdge Monitoring system, you’ll be able to actually see what the clouds do to the production of solar energy. In the image above, there are two images. The one on the left is a perfect bell curve – that is indicative of a sunny day. The one on the right is a cloudy day, as you can see by the graph, there is still a great deal of energy being produced.
