Solar panels are one of the best investments you can make for your home. They cut bills, reduce reliance on the grid and work quietly for years without you having to think about them. But like any investment, they only deliver their full value when they are properly looked after.
That is where cleaning comes in. Panels sit outside day and night, constantly exposed to the elements. Dirt, dust, bird droppings and pollen soon settle on the surface. Even a fine layer of grime blocks sunlight, cutting efficiency and forcing you to buy more electricity from your supplier.
It’s easy to overlook, but the impact is real. A thin film of dirt can reduce output by up to 20%.
The hidden cost of dirty panels
When panels are not cleaned, you end up paying twice. First in the form of lower energy generation, and again in higher bills from the grid. For something designed to save money, it is a frustrating waste.
There is also a long-term risk. Dirt and moss trap heat and wear down the glass over time. Scratches, streaks and surface discolouration shorten the lifespan of your system, bringing forward costs you should not need to face for decades.
Why cleaning makes financial sense
Cleaning is a small step with big rewards. Done properly, it improves efficiency immediately, lowers bills and protects the surface of your panels.
At Sheerwater Clean, we keep things straightforward:
- Purified water and soft-brush poles remove dirt without scratching the surface.
- Most work is carried out from the ground, avoiding the risks that ladders bring.
- Every property is risk assessed before we start, so we only ever attempt what is safe.
The result is a service that restores performance and extends system life without putting your panels at risk.
How often should you clean?
For most homes, once or twice a year is enough. Spring and autumn are the most common times, when pollen, blossom and falling leaves cause the biggest build-up.
If your panels are shaded by trees or attract a lot of birds, you may need cleaning more often. We will always give honest advice based on your property, not a one-size-fits-all answer.
