Yes, solar panels will still generate electricity on cloudy days, just about 20-30% of its full capacity. As a result, clouds reduce the amount of sunlight that reaches your panels. Solar panels are designed to use direct and indirect sunlight to generate electricity. No worries, you are still producing power even when the clouds are up there!

Do Solar Panels Work In The Cold?

Solar panels’ production is more reliant on the amount of the sunlight that reaches the panels, than the temperature of the air surrounding them. However, since we are dealing with electricity, it is known that as the panels get hotter, they produce less energy even with the same amount of sunlight. The panels are tested at a temperature of 25 degrees C- about 77 degrees F, and heat can reduce that efficiency by 10-25%. That’s why the best production months for Texas are during spring and fall when days are already long, but the temperature is mild!

How About Rainfall?

Solar panels produce electricity even on rainy days due to visible sunlight getting through the rain. Rain is beneficial for solar panels, as it helps to keep your panels operating efficiently by washing away dust, pollen, birds’ droppings, and or debris. So rainy days are solar-shower days!

And Snowfall?

A little bit of snow, as in the case of rain, can be useful for cleaning solar panels. The sunlight can still pass through a thin cover of snow. Designers always install solar panels at the most effective angle to help with sun reflection and the fall of snow if needed. Fortunately, we do not have to deal with this as much, here in Texas!

Solar Panels in Hail

Solar panels could possibly be damaged by a heavy hailstorm, but it is very rare. Fortunately, if it happens, any potential damage caused by severe weather conditions would be covered by your homeowner’s insurance, just like your roof. Solar Panels are tougher to break than your roof, so you can sleep calmly! Don’t worry about solar panels and hail – panels will withhold the hail and if not we will work with your insurance to fix them if needed!

Solar Panels In The Wind

Most solar panels can withstand winds up to 100mph. Every solar installation is firmly attached to the roof. The panels must be properly mounted to a sturdy, immovable surface to pass the final inspection.
