PV Solar Panel Cleaning
Professional cleaning of photovoltaic installations — rooftop, ground-mounted and BIPV. De-mineralised water, methods safe for anti-reflective coatings. Restore full system output.
Why clean panels produce more energy
Soiling — dust, bird droppings, pollen, soot, moss — can reduce PV output by up to 20–30%. Regular cleaning is not a cost but an investment that pays back within the first season.
Scope of works
- Panel washing with de-mineralised (RO/DI) water — streak-free, no mineral deposits
- Removal of bird droppings, moss, lichen and soot
- Aluminium frame and connector cleaning
- Visual inspection for mechanical damage and microcracks
- Inverter and external junction box cleaning
- Flat and pitched roof work — fall-arrest equipment, certified technicians
- Ground-mounted arrays — sweeping and low-pressure washing
Installation types
Residential, commercial, industrial and logistics buildings. Work with appropriate fall-arrest, no damage to roofing material.
Large commercial arrays — mechanised or manual washing depending on row spacing and access.
Panels integrated into the building envelope — cleaning combined with facade maintenance, rope access or aerial platform.
Methods used
- Telescopic poles with RO/DI filtration — streak-free, safe for coatings
- Low-pressure washing (max. 30 bar) — no risk of seal damage
- Biocidal agents for moss/lichen removal — PV-approved
