How Much Power Do Solar Panels Produce On A Cloudy Day

Solar panels do produce electricity in cloudy weather.

How much power do solar panels produce on a cloudy day. Anyone who has gotten sunburned on a cloudy day knows that solar radiation penetrates clouds. Yes just not quite as well on a cloudy day typical solar panels can produce 10 25 of their rated capacity. For that same reason solar panels can still produce electricity on cloudy days. That may not seem like a lot but as the saying goes the sun will come out tomorrow and then you are back up to full power.

The exact amount will vary depending on the density of the clouds and may also vary by the type of solar panel. So far this year the day on which i had the highest production was a perfectly clear day in may. Your solar panels will still produce on average 25 of their normal production on a fully cloudy day. But depending on the cloud cover and the quality of the solar panels efficiency can drop to anywhere from 10 to 25 percent of the energy output seen on a sunny day.

They don t produce as much electricity as they do on sunny days but they have been shown to produce 25 of what they produce on. Thanks to net metering laws you will not experience any loss of electricity. For example if your solar panel lists a power temperature coefficient of 0 30 this means that it produces 0 30 less power for every one celsius degree increase in temperature.
