Solar & battery
Do solar panels work in winter?
Yes. Solar panels work on daylight, not heat, so cold UK winter days still produce power. UK winter (December–February) typically generates 15–25% of a system's annual output; summer (May–July) generates 40–50%. Counterintuitively, cold weather slightly improves panel efficiency per unit of sunlight, because cells are less resistive when cool.
