Keeping your solar PV panels clean isn’t just about appearances — it’s about performance, savings, and protecting your investment.
Even in the UK, where we get our fair share of rain, panels can build up dust, bird droppings, pollen, and other debris over time.
Left unchecked, this can block sunlight and cut your energy production by 10–30% over the course of a year.
Independent studies show that a good clean can restore 10–20% (or more) of lost output. That’s energy — and money — straight back in your pocket.
Grime, moss, or lichen don’t just reduce power. They can create “hot spots” and cause uneven heating, which may shorten the life of your panels.
Annual cleaning helps you spot small problems early, before they turn into bigger (and more expensive) issues.
Regular upkeep also prevents stubborn soiling that’s harder to remove later.
Many manufacturers and installers require proof of regular maintenance — including cleaning — for warranty claims to be honoured.
Clean panels work harder for you all year, giving you maximum energy output, savings, and environmental impact.
While rainwater will remove some loose dirt, it won’t shift baked-on deposits — especially after pollen season, strong winds, or heavy bird activity.
That’s why a thorough professional clean (or careful DIY) once a year is essential.
An annual clean is a small step that delivers big rewards:
Higher efficiency and energy savings
Longer panel lifespan
Reduced risk of costly repairs
Peace of mind with warranty compliance
