Introduction
Solar panel cleaning is one of the most misunderstood parts of owning a solar system in Pakistan. Output drops after a few months, and confusion begins — that’s where the most common solar cleaning questions come from.
People expect low electricity bills for years, but dust, smog, salt, and pollen reduce light transmission quickly. PHS answers these questions using field-tested SOPs and safety-first practices.
- Frequency depends on city and rooftop exposure
- Safety & damage prevention are non‑negotiable
- Controlled water flow prevents stains and seal issues
- Proper tools protect coatings and glass
Quick Help
If your output dropped, it may be dust film — not a system fault.
Avoid DIY wiping and pressure washers — they cause scratches and seal damage.
Use SOP-based cleaning with temperature checks for zero-risk results.
