Seasonal Solar Panel Care: Tips for UK homeowners

Solar panels are a smart, long-term investment for your home. But to get the most out of them throughout the year, a bit of seasonal care goes a long way. From cleaning to monitoring, these simple tips will help your system perform at its best—whatever the British weather throws your way.

Spring: A Fresh Start

As we shake off the winter chill, spring is the perfect time to give your panels a check. A build-up of dirt, moss, or leaves can reduce efficiency, so it’s worth giving everything a once-over.

• Check for debris: Look out for leaves, bird droppings or anything else that might be sitting on your panels.
• Give them a gentle clean: Use clean water and a soft brush or sponge if needed—nothing abrasive.
• Monitor performance: Keep an eye on your generation figures. A drop could mean it’s time for a professional inspection.

Summer: Maximise Peak Generation

With longer days and stronger sunlight, summer is when your solar panels really shine. But even in ideal conditions, there are a few ways to keep things running smoothly.

• Clear dust and pollen: A quick rinse with a hose can help maintain maximum efficiency.
• Trim nearby trees: Keep foliage in check to avoid unwanted shading.
• Check ventilation: Make sure airflow around your inverter or battery system isn’t blocked.

Autumn: Get Ahead of the Weather

As the weather turns and leaves start to fall, your panels can be more exposed to wind and debris. It’s a good time to prepare for the colder months ahead.

• Remove leaves and moss: This prevents blockages and maintains airflow around roof-integrated systems.
• Inspect fixings: Autumn winds can put strain on your system, so it’s worth checking that everything’s secure.
• Consider a check-up: A quick maintenance visit now can save issues down the line.

Winter: Stay Efficient in Low Light

Even in winter, your solar panels will continue to generate electricity. Cold weather actually helps solar cells perform more efficiently—but short days and cloud cover can affect output.

• Brush off snow (if needed): A soft brush can help clear light snow. Avoid climbing on the roof yourself.
• Watch your battery: If you’ve got one installed, cold weather may affect charging times and storage capacity. Read more about battery storage.
• Keep an eye on performance: Your monitoring app or inverter display can help you stay on top of any changes.

Safety First

We always recommend using a professional for inspections or any work that involves climbing or electrics. Most visual checks can be done safely from the ground.
