Solar Panel Cleaning Chemicals for the Indian Solar Industry
- INDUSTRY OVERVIEW
Dirty Solar Panels Are Costing You Money — Right Now
In India’s dusty, high-pollution environment, solar panels lose 15 to 35% of their energy output within weeks of last cleaning. Water alone cannot remove oily contamination, bird dropping residues and hard water mineral scale that bind to panel surfaces — spreading contamination rather than removing it.
For a 500 KW installation losing 25% output — that is ₹1.5 to 2.5 lakhs of lost energy value every month. The cost of professional chemical cleaning is a fraction of that loss.
REFA supplies specialist solar panel cleaning chemicals specifically developed for Indian conditions — restoring maximum energy output and protecting panel surfaces from rapid resoiling.
Solar Installations We Serve
Utility Scale Solar Farms
Large ground-mounted solar installations requiring high-volume, cost-effective panel cleaning at scale.
Industrial & Commercial Rooftop Solar
Manufacturing plants, warehouses, office buildings and commercial establishments with rooftop solar installations.
Solar EPC Companies
Engineering, procurement and construction companies requiring post-installation commissioning cleans before handover.
Solar O&M Service Providers
Operations and maintenance companies managing solar farm portfolios requiring reliable chemical supply for cleaning programs.
What We Remove
Dust & Particulate Matter
Fine dust, sand, fly ash and airborne particulates — including the electrostatic charge that causes rapid resoiling after standard water washing.
Bird Droppings
Dried and hardened bird dropping residues that cause hot spots and chemically etch into panel glass if left uncleaned
Oily & Adhesive Contamination
Industrial pollution, vehicle exhaust and factory emissions that bind dust to panel surfaces — making water-only cleaning ineffective.
Hard Water Mineral Scale
Calcium carbonate deposits left by previous hard water washing — reducing light transmission and accelerating resoiling.
Pollen & Biological Deposits
Seasonal pollen, early-stage algae growth and biological deposits — common in agricultural areas and humid climates.
Construction & Installation Residues
Adhesive residues, cement splatter and installation contamination on newly commissioned panels.
Our Solar Panel Cleaning Chemical Range

Cleaning is Not a Cost. It is an Investment.
Solar panel cleaning is one of the highest-ROI maintenance activities available to a solar plant operator — yet most operators underestimate the financial impact of soiling loss.
| 500 KW Installation — Soiling Loss Calculation Impact | Impact |
|---|---|
|
Output loss after 6 weeks of soiling 100 to 175 KW below rated capacity |
100 to 175 KW below rated capacity |
|
Daily generation loss (8 hours sunlight) 800 to 1,400 KWh per day |
800 to 1,400 KWh per day |
|
Lost energy value at ₹6 per unit ₹4,800 to ₹8,400 per day |
₹4,800 to ₹8,400 per day |
|
Monthly loss |
₹1.44 lakhs to ₹2.52 lakhs |
The cost of regular REFA chemical cleaning is a fraction of this loss — making a properly managed panel cleaning program one of the most straightforward ROI decisions in solar plant operations.

Real Results for Solar Operators
- Industry
Industry Industrial Rooftop Solar Installation, Manufacturing Plant, North India
Challenge: Challenge 300 KW rooftop solar installation measured at approximately 28% below rated capacity. Water-only cleaning not restoring output — oily industrial pollution film and hard water mineral deposits identified as the cause.
REFA Solution: REFA heavy duty solar panel cleaner applied manually — full panel surface coverage, brief contact time, clean water rinse. REFA scale remover applied to panels with visible mineral deposits before main cleaning. No product names disclosed.
- FAQ
Frequently asked questions
How often should solar panels be cleaned in India?
Cleaning frequency depends on your location and local pollution levels. In high-dust industrial areas monthly cleaning is recommended. In moderate urban areas quarterly is typical. We can help you calculate the optimum cleaning frequency based on your installation and measured soiling loss.
Is water alone not sufficient for cleaning solar panels?
Water alone is insufficient for panels contaminated with oily films, bird droppings or hard water mineral scale. These require chemical cleaning to remove completely — water washing alone spreads oily contamination rather than removing it.
Will your cleaning chemical damage the anti-reflective coating on my panels?
No. All REFA solar cleaning chemicals are specifically formulated and tested to be safe for anti-reflective coated solar panel glass. We do not use harsh acids, strong alkalis or abrasive ingredients that could damage coatings.
Do you supply in bulk quantities for large solar farm operations?
Yes. We supply from 20 litre jerry cans to 200 litre drums and IBC containers — suitable for large utility-scale solar farm cleaning operations.
