Solar Panel Cleaning

Maximise Solar Efficiency
Dirt and grime can block sunlight and reduce energy output. Our gentle, streak-free cleaning boosts panel performance and ensures your system delivers the savings you expect — year after year.

 

✅ “Dirty panels can lose up to a quarter of their power. Professional cleaning restores efficiency, protects your warranty, and keeps your investment paying back at its best.”

 

🌞 Performance Impact of Dirty Solar Panels

1. Reduced Energy Output

   • Dust, pollen, traffic film, bird droppings, moss, and general grime block sunlight from reaching the solar cells.

   • Studies and industry reports show efficiency losses of 5–20% are common, depending on environment.

   • In agricultural, industrial, or coastal areas (salt spray), losses can exceed 25–30% if left uncleaned.

2. Accelerated Wear

   • Build-up of dirt causes uneven shading, which can lead to “hot spots” that overheat sections of the panel, stressing the cells.

   • This reduces long-term panel life and risks invalidating warranties (many manufacturers stipulate regular cleaning).

3. Financial Cost

   • A 10% drop in efficiency on a domestic 4kW system can mean £100–£150 lost per year in the UK.

   • On commercial systems, losses can run into thousands annually.

🧼 Performance Impact of Our Professional Cleaning

1. Restored Efficiency

   • Proper cleaning (using pure water systems and non-abrasive techniques) typically restores 10–25% of lost performance immediately.

   • Panels appear visibly clearer, allowing maximum light absorption.

2. Maximised Reteruun on Investment (ROI)

   • Customers protect their investment, ensuring their solar panels deliver the maximum return and payback period stays on track.

   • Example: For a homeowner with a £6,000 system, even a 10% efficiency gain could add £1,000–£1,500 over 10 years.

3. Longevity & Warranty Protection

   • Professional cleaning prevents damage from scratches (caused by DIY cleaning or abrasive dirt).

   • Complies with manufacturer maintenance requirements.

   • Reduces “hot spot” risks, extending system lifespan.

4. Safety & Convenience

   • Avoids homeowners climbing on roofs or using unsuitable chemicals.

   • Exterior cleaning professionals use specialised equipment to reach safely and clean effectively.
