Do Solar Panels Work In The Winter?

People ask us this all the time, especially here in Somerset where the winters can be long and grey.

The answer is yes. Solar panels do work in the winter. The caveat is that they don't produce as much.

Key Takeaways

• Solar panels work all year round. They need daylight, not heat.
• Winter output is lower. Shorter days and a lower sun mean less energy.
• Sizing is what really matters. A well designed system makes up for the dip.

Why Panels Produce Less In Winter

Solar panels turn daylight into electricity. In winter the days are shorter, the sun sits lower in the sky and there are more cloudy days. So your panels have less light to work with.

They still generate, even on a dull day. Cold weather is not a problem for them at all. It is the amount of light that changes.

Sizing Your System Correctly

What really matters is making sure your system is sized correctly at the beginning. Get that right, and it compensates for the winter dip and still meets your demands as best it can.

When we design a system we look at how much energy you use across the whole year, not just in summer. We look at your roof, which way it faces and any shading. Then we work out how many panels make sense for your home.

Where A Battery Helps

A home battery can make a big difference in winter. With the right tariff, it can charge overnight when electricity is cheaper and run your home through the day. Our guide Do You Actually Need A Home Battery? explains when it makes sense.
