Issue 01
Dust + Soot Layer
A thin film of urban soot, fly ash, and industrial particulates absorbs sunlight before it ever reaches the cell.
India has 100 GW+ of solar - most of it is underperforming
Recover Lost Power.
VARCHAK restores commercial rooftop solar performance by removing dust, soot, scaling, and informal-cleaning damage risks - built for 50 kW+ Indian industrial plants.
₹27,000/month
Estimated revenue lost on a 100 kW commercial rooftop due to soiling at ₹9/unit and ~25% loss.

The Invisible Bleed
Your panels are losing power right now.
Your inverter app shows lower generation. Your electricity bill confirms it. But because the loss is gradual, dirty panels become a silent monthly leak - invisible until it's expensive.
Issue 02
Hard-Water Scaling
Borewell water leaves mineral deposits and white scaling on glass - permanent generation loss until properly treated.
Issue 03
Cleaning Damage
Wrong brush, wrong water, wrong technique - each scratches the anti-reflective coating, compounding loss with every "cleaning."

25%
Indian industrial rooftops typically see 15–30% loss. Default is the 25% midpoint.
Model assumes 120 units/month per kW of clean generation (≈ 4 peak-sun-hours × 30 days), then applies your soiling loss. Actual results vary by location, tilt, season, cleaning method, and tariff schedule.

Services
Maintenance built for Indian industry.
Not generic cleaning. Each service is engineered around the way Indian commercial rooftops degrade - and how to reverse it.
01
Performance Cleaning
Dust, soot, residue removal
Removal of urban soot, fly ash, bird droppings, and industrial residue that blocks generation on commercial rooftops.
02
Low-TDS Water Treatment
Prevents scaling and deposits
Panel-safe cleaning designed to prevent hard-water scaling, mineral rings, and permanent white deposits on glass.
03
Rooftop AMC
Scheduled commercial maintenance
Structured Annual Maintenance Contracts for 50 kW+ commercial and industrial solar assets, with written terms and liability.
04
Generation Reporting
Proof after every service visit
Post-service reports comparing generation before and after every visit. Restored performance - documented, not promised.
05
Damage Risk Inspection
Catch degradation before losses
Early detection of scaling, micro-scratches, hotspots, hot junctions, and informal-cleaning damage before they cost generation.
How It Works
From dirty panels to restored yield.
A structured four-step engagement - not a one-off scrub. Each step is documented, repeatable, and auditable.
Step 01
Assess
We review plant size, location, soiling exposure, current cleaning method, and your expected generation loss.
Step 02
Clean Safely
Our team uses panel-safe, low-TDS cleaning methods designed for Indian industrial rooftops - no scratches, no scaling.
Step 03
Verify
After every visit, we compare generation data and document visible restoration in a service report.
Step 04· AMC
Maintain
You move from irregular cleaning to a scheduled AMC that protects output month after month.
Why VARCHAK
Built like an engineering service - not a cleaning vendor.
Four operating principles every visit follows. No shortcuts. No cosmetic theatre. Just measurable recovery.
Principle 01
No Panel Damage
Cleaning is designed to protect anti-reflective glass and avoid abrasive surface damage.
Principle 02
Low-TDS Cleaning
Avoid borewell-water scaling that leaves permanent white mineral deposits on panel glass.
Principle 03
Proof After Service
Every visit is followed by a generation report - not just a verbal update.
Principle 04
AMC Discipline
Scheduled commercial maintenance replaces irregular, informal cleaning.
Water beads off clean glass
Restoration you can see - and measure.
Informal Cleaning vs Professional AMC
Your sweeper is not a solar technician.
Informal cleaning has hidden costs that don't show up on a bill - until the panels start showing them.
Informal Cleaning
- Tap or borewell water
- Abrasive cloths or hard brooms
- No documentation
- Worker fall liability risk
- Damage builds invisibly
Professional AMCVARCHAK
- Low-TDS filtered water
- Scratch-safe tools
- Digital generation report
- Written service contract
- Early damage detection
Who We Serve
Built for 50 kW+ rooftops.
Minimum system capacity: 50 kW. VARCHAK does not service single-family homes - only commercial and industrial assets where generation loss has real financial weight.
