Solar Panel Cleaning Services — Island-Wide, Sri Lanka
Solar panels only generate at their best when sunlight reaches the cells directly. Moss and algae are the most common culprits we see on Sri Lankan rooftops, along with dust, pollen, bird droppings, and general grime — all of it builds up on the glass surface over time and blocks some of that light. The panels keep working, they just work less efficiently, often without anyone noticing until they check their output.
Cleaning panels yourself carries real risk: the wrong tools or detergent can scratch the glass surface, and working at roof height without the right equipment is dangerous. Our service handles both the access and the cleaning method with care.

When to clean solar panels
As a general guide, every two to three months — more often if your property is near a dusty road, construction site, or the coast where salt air adds to the buildup. Moss and algae are usually the biggest factor: they take hold quickly in Sri Lanka's humidity, especially on panels that sit in partial shade or don't drain fully after rain.
Frequently Asked Questions
How often should solar panels be cleaned in Sri Lanka?
Roughly every two to three months for most homes, more frequently in dusty or coastal areas.
Does dirt actually reduce solar panel output?
Yes — a layer of dust, pollen, bird droppings, or moss and algae blocks some sunlight from reaching the cells, which reduces how much power the panels generate. Moss is the most common buildup we see on panels in Sri Lanka.
Can I clean my own solar panels?
You can, but the wrong tools or cleaning products can scratch the panel surface, and working at height carries real risk. Professional cleaning uses tools and technique matched to the panel surface.
Will cleaning damage my panels?
Our process is built around avoiding abrasive tools and harsh pressure on the glass surface.
