What Is Solar Panel Cleaning?
Solar panel cleaning removes dust, pollen, bird droppings and general grime that accumulate on panel surfaces and reduce light transmission to the solar cells underneath. In dusty pre-monsoon conditions common across Uttar Pradesh, uncleaned panels can lose 10-20% of their rated output — a meaningful hit to the savings a solar system is meant to deliver.
Benefits of Solar Panel Cleaning
Recovers Lost Output
Cleaning typically restores generation close to rated capacity within a single visit.
Safe, Non-Abrasive Method
We use soft-brush and deionised or filtered water methods that won't scratch panel glass or damage anti-reflective coatings.
Scheduled or On-Demand
Book a one-off clean or set up a recurring quarterly schedule.
Rooftop-Safe Technicians
Our team follows proper rooftop safety practice, important for tiled or sloped roofs.
Before/After Generation Check
We check generation output before and after cleaning so you can see the actual improvement.
Suited to All System Sizes
From a single residential rooftop to large commercial or industrial arrays.
How Often Should Panels Be Cleaned?
For most homes across Lucknow, Ayodhya and Kanpur, we recommend cleaning every 3 months, with an additional clean just before monsoon when pre-monsoon dust levels peak. Properties near construction sites, unpaved roads or agricultural areas may need more frequent cleaning given higher ambient dust.
Up to \u20B91,08,000 Government Subsidy Available — as applicable under current Central + State benefits for eligible residential rooftop solar installations in Uttar Pradesh. Eligibility depends on system size, applicable government guidelines, approvals and scheme eligibility, and is subject to change.

Why Choose Sunroof Solar Solutions
Improper cleaning — hard brushes, high-pressure jets or hard water — can scratch panels or leave mineral deposits that reduce output further. Our technicians are trained specifically on solar-safe cleaning methods.
Frequently Asked Questions
Depending on location and season, uncleaned panels can lose 10-20% of rated output, with the highest losses typically just before monsoon.
You can, but hard brushes, high-pressure water or hard tap water can scratch panels or leave deposits — professional cleaning uses methods designed specifically to avoid this.
A standard residential system typically takes 30-60 minutes; larger commercial or industrial arrays take longer depending on panel count.
