Keep Your Solar Panels Working at Full Potential with Expert Cleaning
Installing solar panels is a long-term investment in energy efficiency and lower utility bills. But like any external surface, panels are exposed to the elements — including dust, pollen, bird droppings, tree sap, algae, and general atmospheric grime. Over time, this dirt can reduce how much sunlight reaches the photovoltaic cells, directly lowering how much energy your system generates.
At Streak Free, we offer professional solar panel cleaning in Gloucester and surrounding areas, helping homeowners and businesses maintain optimal panel performance year-round.
Why Clean Your Solar Panels?
Solar panels don’t have any moving parts, so they’re often seen as maintenance-free. However, regular cleaning plays a crucial role in keeping them efficient and ensuring you get the best possible return on your investment.
Common issues affecting solar panel performance include:
• Dust and dirt build-up: Especially during dry months or near agricultural areas
• Bird droppings: These can block large portions of a panel’s surface and do not wash off easily with rain
• Moss or algae growth: Particularly common on rural or shaded properties
• Tree sap and pollen: Sticky, seasonal contaminants that affect light transmission
Even a thin layer of grime can significantly reduce output. According to several industry studies, solar panels can lose between 5% and 20% of their efficiency when they’re dirty — depending on location and build-up.
How Solar Panel Cleaning Improves Efficiency
Solar panels work by converting sunlight into electricity. The clearer and cleaner the surface, the more light can be absorbed by the photovoltaic cells underneath the glass. When grime obstructs this light, energy production drops.
A professionally cleaned panel allows for:
• Improved energy yield: More electricity generated, especially during peak sun hours
• Better return on your investment: Keeps your energy bills as low as possible
• Extended system lifespan: Regular maintenance helps prevent permanent staining or corrosion
• Warranty protection: Some manufacturers recommend or require periodic cleaning as part of their warranty terms
In short, clean panels produce more electricity — and cleaning is a small, affordable step that protects a much larger investment.
Our Cleaning Process
We use a safe, non-abrasive cleaning method that’s specifically suited for solar installations. No harsh chemicals or high-pressure systems are used.
Our method includes:
• Purified water systems: We use deionised water to prevent spotting and streaking
• Soft brush tools: Designed for solar panel glass, preventing scratches or seal damage
• Ladder-safe and long-reach equipment: We work from the ground where possible or use harnesses and standoffs to access roof-mounted systems safely
• No detergent runoff: Environmentally friendly with no risk to your garden or wildlife
We can clean residential arrays, roof-mounted systems, garage or outbuilding panels, and even ground-level installations.
How Often Should You Clean Solar Panels?
The frequency depends on your location and surrounding environment. In general:
• Urban or suburban areas: Once every 6–12 months is typically sufficient
• Near trees, fields, or bird nesting areas: Every 3–6 months may be necessary
• After major weather events: Heavy pollen, high winds, or storms can rapidly increase build-up
We’re happy to assess your property and recommend a cleaning schedule that suits your system and environment.
