Is Dirt Reducing Your Solar Panels' Efficiency?
Dust, bird droppings, pollution and moss build up gradually on solar panels – and because it happens slowly, most people don’t notice until their energy bills start creeping up.
Even a relatively thin layer of grime can block enough sunlight to meaningfully reduce output.
Regular professional cleaning is one of the simplest ways to protect your solar investment, maintain energy savings, and extend the lifespan of your panels for years to come.

Why Solar Panel Cleaning Matters
Restore Lost Efficiency
Dirt, dust and bird droppings block sunlight and reduce your panels’ ability to generate energy. A thorough professional clean helps restore output and improve your system’s day-to-day performance.
Protect Your Long-Term Investment
Regular cleaning helps prevent the build-up that can degrade panel surfaces over time. Keeping them clean is one of the easiest ways to extend the lifespan of your system and protect its long-term value.

Frequently Asked Questions
How often do solar panels need to be cleaned?
For most properties in the UK, once or twice a year is recommended. If your panels are in a particularly dusty location, near trees, or in an area with heavy bird activity, more frequent cleaning may be beneficial. A yearly professional clean as a minimum helps maintain output and keeps your warranty conditions in good standing.
How much does solar panel cleaning cost?
Pricing depends on the number of panels, the property type and access. The easiest way to get an accurate price is to request a free quote.
Will cleaning damage my solar panels?
Stronghold uses non-abrasive techniques and eco-friendly solutions specifically chosen to clean panels safely without scratching or degrading the surface. We never use harsh chemicals or high-pressure methods on panels.
Can you clean solar panels on commercial properties?
Yes. We service both residential and commercial properties across Suffolk. For larger arrays or commercial sites, just let us know when requesting your quote and we’ll advise on the best approach and scheduling.
Do clean solar panels really make a difference to energy output?
Yes, dirty panels can lose a significant portion of their generating capacity. Dust, bird droppings and organic build-up block sunlight from reaching the cells. A professional clean can help restore output noticeably, particularly if panels haven’t been cleaned for some time.
Do I need to be at home for the clean?
Not necessarily. As long as we can safely access the panels and everything is agreed beforehand, we can often complete the work while you’re out. We’ll confirm the details with you before the visit.
