Solar and weather

Last updated: 23 June 2025

Explore how solar technology adapts to different weather conditions to deliver reliable energy all year round.

Do solar panels work on cloudy days?

Yes, solar panels don’t need hot, sunny days to work – they need light, not heat. Even when it’s cloudy, there’s still sunlight getting through, and solar PV generates significant amounts of electricity. Thanks to technological advancements, modern solar panels can turn sunlight into electricity more efficiently. They can also be set up in a way that works best for your area. Installers can adjust the angle and direction of the panels to get the most sunlight, based on your local weather and location.

Do solar panels work in the snow?

Yes, as long as some sunlight reaches the panels, they will still produce electricity. In fact, solar panels often work more efficiently in cooler temperatures. Snow typically melts quickly off panels due to their dark surface and tilted position, which also helps clean them.

Can solar panels handle harsh weather?

Yes, solar panels are typically designed to withstand tough conditions, including rain, hail, heavy snow, and strong winds. They are tested against international durability standards and are mounted securely to stay in place even in storms.

Can solar power work at night?

Yes, solar panels combined with energy storage systems, like batteries, capture and store extra energy produced during the day. Then, when the sun sets, they use that stored energy to power our homes 24/7.

Can solar power work all year round?

Yes, solar panels work in every season. While they produce the most energy in summer, they still generate electricity throughout the year. Good system design and smart energy use can help maximise solar benefits year-round.

How does solar work with other renewables, like wind?

Solar energy fits perfectly with other renewable sources. For example, solar often generates the most energy during the day and in summer, while wind energy tends to be stronger at night and in winter. Together, they help create a more balanced and reliable renewable energy system.
