Technical FAQ

Frequently Asked Questions by Solar Asset Managers

Does rainfall keep UK solar panels sufficiently clean?

No. Rain contains dust particles and atmospheric smog. While heavy rain may wash away loose dust from steep residential pitches, low angle commercial roofs (typically 5 to 15 degrees) and farm arrays accumulate stubborn baked on organic film, bird fouling, pollen crust and traffic soot along the lower cell boundaries. Mechanical agitation with pure water is necessary to restore light transmission.

Will cleaning invalidate our solar panel warranties?

Only if improper methods are used. Tier 1 panel manufacturers specifically stipulate that abrasive powders, alkaline detergents, metal scrapers, and high pressure jet washers must never be used. EcoServ uses pure, demineralised deionised water and certified soft nylon bristles operating at low cleaning pressure, fully compliant with manufacturer terms.

Do you need an on-site water supply?

Not necessarily. While connecting to an on site commercial water tap helps on multi day cleans, our mobile cleaning units frequently deploy with on board pure water bowsers, allowing full self sufficiency on remote farm barns or greenfield utility sites.

What health and safety paperwork do you supply before commencing?

We supply complete, site specific risk assessments and method statements (RAMS), COSHH assessments (for water purification media), proof of public and employer liability insurance, operator working at height certificates, and equipment maintenance inspection logs.
