Solar Panel Cleaning

Precision Solar Panel Cleaning

Dirty panels = lost efficiency. Dust, pollen, bird deposits, and atmospheric pollutants create an insulating layer that blocks photon absorption and reduces your energy yield by up to 25%. Our chemistry-led, low-pressure protocol restores peak performance without risking micro-scratches or panel degradation.

The Seven-Step Solar Clean System

Step 1: Pre-Clean Assessment
Visual inspection and efficiency baseline measurement. We identify contamination type, panel condition, and any existing damage before we begin.

Step 2: Dry Debris Removal
Soft-bristle brushing to remove loose particulates without water. This prevents scratching and prepares the surface for chemical treatment.

Step 3: Biocide Application
Targeted application of pH-neutral, panel-safe biocide to break down organic matter—algae, lichen, and biofilm—without damaging anti-reflective coatings.

Step 4: Dwell Time
Controlled dwell period allows chemistry to penetrate and lift contaminants at the molecular level. No scrubbing, no pressure, just science.

Step 5: Low-Pressure Rinse
Pure water rinse at <40 bar to remove dissolved contaminants without stressing panel seals or frames. We use deionised water to prevent mineral deposits.

Step 6: Edge & Frame Detailing
Manual cleaning of panel edges, frames, and mounting hardware where debris accumulates and can cause long-term corrosion.

Step 7: Post-Clean Verification
Final inspection and efficiency check. We document the clean and provide before/after data so you can measure the performance improvement.

Why Low-Pressure Matters

High-pressure washing can force water past panel seals, damage anti-reflective coatings, and void manufacturer warranties. Our sub-40 bar process is engineered to clean safely—protecting your investment while maximising light transmission.

Frequency & Maintenance

Most UK installations benefit from biannual cleaning—spring and autumn—to counter pollen season and leaf fall. High-pollution or coastal sites may require quarterly service. We offer fixed-price maintenance contracts with scheduled visits and performance tracking.

Commercial & Portfolio Services

Managing multiple sites? We provide centralised scheduling, compliance documentation (RAMS/COSHH), and standardised reporting across your entire solar portfolio. One protocol, consistent results, minimal admin.
