"Do I need to get my solar panels cleaned?" is one of the questions we hear most.
For most homes in the UK, the honest answer is: not very often. Panels sit at an angle, so regular rain washes off a lot of everyday dust.
Where it's worth keeping an eye out:
• Bird droppings or moss that sit on the glass and don't wash away
• Leaves building up along the bottom edge in autumn
• Homes near farms, busy roads or the coast, where grime can build up faster
If something does need sorting, please don't climb up there yourself. Working at height is dangerous, and harsh brushes or chemicals can damage the panels. A specialist with the right kit can do it safely.
Have you ever had your panels cleaned, or do you leave it to the British weather? Let us know in the comments.
