Why is cleaning a floating installation so important?

Floating solar installations, also known as floating PV, sit on lakes, ponds or reservoirs. The water cools the panels, but it also brings extra soiling from algae, aquatic plants, bird droppings and splashed-up dirt. Once those particles stick, less sunlight reaches the panels and your yield drops.

Stubborn soiling can also lead to hotspots: areas where accumulated dirt or minor damage creates extra heat, causing permanent damage over time. Having your floating installation cleaned regularly keeps your energy output stable and prevents costly repairs or premature replacement. Read more about solar panel cleaning.

How often should you have a floating installation cleaned?

That varies by location and depends on how polluted the water is. Is your installation in an area with lots of birds, insects or algae? Then it’s more likely to get dirty than on a clear lake or an artificial basin with little organic matter.

In general, we recommend cleaning every one to two years. With heavy soiling, a clean every six months may be needed. Want to know the ideal interval for your installation? Get in touch for tailored advice. We take the water quality, the location and other environmental factors into account.

All frequently asked questions
Doesn’t rain wash away enough dirt?

At most, rain removes loose dust, but it leaves stubborn dirt behind. Bird droppings, mud and other stubborn soiling stay put, which lowers your yield.

Do I need to switch off my installation during cleaning?

No, your installation never needs to be switched off during cleaning.

How can I tell my installation needs cleaning?

Look out for visible soiling such as algae growth, bird droppings and streaks on the panels. Your monitoring system will also often show a sudden drop in yield.
