Solar panels (photovoltaic modules) convert sunlight into electricity, but their efficiency can degrade over time due to the accumulation of dust, dirt, bird droppings, pollen, and pollution particles.
- Light Blocking: Dust and debris reduce the incident sunlight reaching the PV cells.
- Hot Spots: Uneven shading causes localized heating, potentially damaging cells.
- Spectral Changes: Some pollutants absorb or scatter specific wavelengths, affecting conversion.
- Reduced Output: Studies show efficiency losses of 5% – 30%, depending on the local environment.
Cleaning your solar panels is one of the most direct and economical methods to restore or enhance performance. Regular cleaning keeps your panels working at their best, saving you money and helping to extend their lifespan.
For optimal efficiency, we recommend cleaning your solar panels at least once every 12 months. Be sure to check your manufacturer’s guidelines and warranty for specific recommendations.
Our Solar Panel cleaning Service
We clean your solar panels using the Reach and Wash system, which allows us to safely and effectively access high or hard-to-reach areas. This system enables our operatives to clean panels using extendable poles with brush heads and jets of pure hot or cold water, all without harsh chemicals. It’s an eco-friendly and highly effective method that removes dirt and debris while helping to protect the longevity and performance of your solar panels.
The result? Spotless panels and improved efficiency, achieved safely and sustainably.
For heavily soiled panels, we also offer a specialist chemical cleaning option using products designed specifically for solar panels. If you think your panels might need this, just let us know during your quote, we’ll be happy to walk you through all the available options.
