When people install solar panels, they often think it’s a “set it and forget it” system. And to a point, that’s true. But one key thing that’s often overlooked is how important regular cleaning is — especially here in Ireland, with our rain, sea air, and all the grime that comes with it.
What Happens When Panels Get Dirty?
Dust, bird droppings, sea salt, moss, algae, and even chimney soot can build up on the panels. That layer of dirt blocks sunlight, reducing efficiency by 10–25% or more. That’s money lost over time — and it could shorten the life of your system too.
Doesn’t the Irish Rain Take Care of It?
We’d love to think so — but not really. Rain can leave mineral spots and streaks, and it won’t clean off tougher buildup like moss or oily grime. Think about your car after a few wet days — still needs a proper wash, right? Solar panels are no different.
How Often Should You Clean Them?
It depends where you live, but most homes benefit from a professional clean once or twice a year. Coastal areas, farms, or busy roads might need it more often. Cleaner panels = better performance.
Can I Just Do It Myself?
We don’t recommend it. It can be risky working at heights, and pressure washers or harsh chemicals can damage the panels or void your warranty. Trained professionals have the tools, know-how, and insurance to do it right and safely.

🌤️ Out of sight, out of mind – it’s easy to forget what’s building up on your solar panels. But a quick clean can make all the difference in how they perform.
If it’s been over a year since your last clean, your panels are long overdue.
