Do solar panels work in the winter?
The simple answer is yes. It is daylight, not heat, that generates your electricity, and cold weather doesn't reduce a panel's efficiency, if anything, solar cells work slightly better in cool conditions than on a hot summer roof.
What does change through winter is the number of daylight hours, so a typical system produces less across a December day than a June one. Even so, a well-sized system keeps contributing to your daytime demand all year round, and your assessment models your site's output month by month, not just at its summer peak.

Rising and volatile winter energy prices make this the right time to see what solar, or simply a better tariff, could do for your bills. Business Solar UK assesses your roof and your electricity data, and our installation partner Solar4Business surveys, designs and installs the system.
