Are Solar Panels Effective in Cloudy Weather?
Introduction
The UK isn’t known for endless sunshine, but does that mean solar panels won’t work in cloudy weather? Here’s the truth.
1. How Solar Panels Work in Clouds
Solar panels can still generate electricity on cloudy days, though output may decrease by 10–25%.
Advanced technology, like monocrystalline panels, performs better in low-light conditions.
2. Factors That Help Mitigate Cloud Impact
Battery Storage: Store excess energy from sunny days for use during cloudy periods.
Efficient Panel Types: High-efficiency panels maximize performance, even with less sunlight.
Optimized Design: Properly oriented panels ensure the best possible output year-round.
3. Long-Term Considerations
Seasonal variations balance out over the year, with summer surpluses covering winter deficits.
Solar is still a viable option for most of the UK, even with its overcast climate.
