As we move into the autumn months, the British weather turns colder and wetter. Many homeowners are wondering “How do solar panels perform in the rain, snow or even hail?”
At SolarTherm UK, we have helped thousands of homeowners save money with a solar installation and we’re here to reassure you, no matter what the UK weather brings, your solar system is built to handle the elements.
Do Solar Panels Work in the Rain?
The short answer is yes, solar panels continue to generate energy even in rainy weather. While heavy cloud naturally reduces sunlight and in turn energy output, modern solar panels are designed to withstand water exposure. Most panels are rated with an IP (Ingress Protection) standard, with high-quality panels typically rated IP-65 or above. At SolarTherm UK, our Bovill.tech all black solar panels have an IP68 rating, ensuring maximum durability against rain and moisture – even in the heaviest downpour, your solar panels remain fully protected and operational.
How Rain Can Actually Help Your Solar Panels
Rain can be beneficial for solar panels. Solar panels are coated with a hydrophobic layer that prevents water droplets from sticking, naturally washing away dust, pollen and debris as it falls, keeping your solar panels clearer and reducing the need for manual cleaning. Keeping your solar panels clean helps maintain their efficiency, so while rainfall may temporarily lower your electricity generation, it contributes to the long-term performance of your solar panels.
Snow, Hail and Extreme Weather
Snow rarely poses a serious threat in the UK, with the average snowfall in Essex and the South East being less than 5cm per year. The angled mounting and smooth surface means that most snow slides off naturally. Heavy snowfall can temporarily reduce output, but it doesn’t damage the solar panels, and like rain, melting snow can help clean the panels.
Hail damage is uncommon, and the high-quality panels we use at SolarTherm UK are built to withstand severe weather conditions including hail and snow.
Worried About Installing Solar Panels in the Unpredictable British Climate?
There’s no need – rain, snow and hail are unlikely to cause any harm or damage to your solar PV system. Modern solar panels are designed for durability and efficiency in all weather conditions. Even in poor weather, your solar panels will still produce well and reduce your energy bills.
