Cleaning Services
Want to keep your solar panels shining bright?
Your photovoltaic (PV) solar energy system is a significant investment, and it’s crucial to keep it operating at peak efficiency. Over time, pollution, leaves, traffic dust, and even bird droppings can accumulate on your solar panels, obstructing their exposure to sunlight and reducing the amount of electricity they generate. This can lead to efficiency losses as high as 25% to 30% in some areas!
Why do I need to clean my solar panels?
Solar panels convert sunlight into electricity. When dirt accumulates on the surface of a solar panel, it compromises the amount of light absorbed and, as a result, the efficiency of the panel is reduced. In addition, rainwater contains airborne dust particles that settle on the surface after the water evaporates, sometimes leaving calcium and hard water deposits.
Whereas soft shading encompasses shading that moves, such as from a tree branch or chimney, hard shading does not move. Hard shading comprises matter such as lichen, bird droppings, or any other object resting on the panels. If your panels are not professionally cleaned regularly, these hard shadings can cause hot spots, leading to cell overheating, back sheet damage, and reduced efficiency of the overall panel.
By regularly cleaning your solar panels, particles such as dust, debris, bird droppings, lichen, and bugs, which can otherwise decrease efficiency by 15-30%, are removed from the surface of the panels.
Why choose us?
This mobile, water-driven brush roller system is designed for cleaning and maintaining photovoltaic systems. It uses mineral-free (demineralized) water for professional cleaning, typically without the need for additional chemicals. The high-pressure cleaner powers the rotation of the SOLA-TECS W, supplying water to the brush roller, which effectively cleans the PV system.
Our teams are also fully equipped with the relevant training to execute the cleaning service.
Why do solar panels need regular professional cleaning?
Dirt, debris, bird droppings, lichen, and bugs settle on panels and can reduce their efficiency by 15-30%. Hard shading like lichen or droppings can also cause hot spots, leading to cell overheating and back-sheet damage.
What equipment do you use to clean solar panels?
We’ve partnered with Kränzle to use the SOLA-TECS W – a mobile, water-driven brush roller system designed specifically for cleaning and maintaining solar panels.
Is solar panel cleaning available for both homes and businesses?
Yes. We offer professional solar panel cleaning for both residential and commercial properties.
Does cleaning affect my solar warranty?
Regular cleaning can actually help you meet the warranty conditions specified by many solar equipment brands, as well as maximising your return on investment.
Why does rainwater alone not keep panels clean?
Rainwater carries airborne dust particles that settle on the panel surface, and once the water evaporates, deposits like calcium and hard water marks can be left behind.
Do you use tap water?
Yes, but we connect our own filtration system to it before we begin washing your panels. The system removes impurities and purifies the water, ensuring only the purest water is used. We don’t use any chemicals, as these can damage solar panels. Combined with our SOLA-TECS brush system, pure water lets us deliver a professional service.
How long does the service take?
It depends on the number of panels at the property, how accessible they are, and the logistics of setting up on site. We can only provide guidelines once we have the scope of work, so it’s best to contact us and we’ll guide you from there.
