A lot of homeowners in North London ask us the same question: “Will solar panels still work in the winter?”
The answer is yes. While output is lower than in summer, solar panels continue generating electricity all year round — even on cloudy days.
🌞 Solar Panels Need Light, Not Heat
Solar panels convert daylight into electricity, not heat. That means even on short, cloudy days in December, your system will still produce energy.
📊 Typical Winter Performance
- In North London, solar systems produce about 25–35% of their annual generation between November and February.
- A 4kW system may generate ~700–900 kWh during the winter months — enough to make a noticeable impact on bills.
🔋 How Batteries Help in Winter
Adding a battery to your system means you can:
- Store daylight energy for use in the evening
- Charge from cheap off-peak electricity and use it at peak times
- Cut grid reliance by up to 85%, even in winter
