Do solar panels work on cloudy days?

Absolutely! It’s actually radiation from the sun, rather than temperature, heat or direct sunlight, that enables solar PV panels to generate electricity.

Solar panels in hot sunny countries are bound to gather more energy, but don’t be fooled into thinking that they won’t work well in the UK. They don’t need constant direct sunlight to work and can still generate electricity when the weather is cloudy. Don’t forget either that Germany is currently the world leader in solar energy generation – not exactly a country well known for its abundance of sun!
