Physical On-Ground Service

Sometimes, a proper module wash
is all your plant needs.

Your panels cannot generate electricity through a layer of baked dust, bird droppings, and urban grime. Professional, scratch-free rooftop cleaning that protects your anti-reflective coating and boosts generation immediately.

The Physics of Soiling

Dirty panels lose 15% to 30% generation quietly.

Dust isn't just cosmetic. Airborne particulate matter, construction silica, bird droppings, and industrial emissions create an opaque blanket that blocks photons from reaching the silicon wafer beneath.

01

The "Rain Cleans Solar" Myth

In Indian cities, light rain mixes with airborne dust, creating a sticky mud slurry. When the sun bakes it dry, it forms a cemented mineral film that rain cannot dissolve.

02

Hotspot Damage & Cell Degradation

A single bird dropping or clump of grime shades a localized section of a solar cell. Under sunlight, that shaded cell stops generating and turns into an electrical resistor, heating up to 100°C+ and risking permanent burnout.

03

Anti-Reflective Coating Scratches

Untrained building cleaners using household brooms, dirty rags, or harsh chemicals scratch the Anti-Reflective Coating (ARC). Once stripped, solar glass permanently reflects sunlight away instead of absorbing it.

04

Thermal Shock Glass Fractures

Throwing cold water onto panels that have been baking under the afternoon sun (60°C+) causes catastrophic thermal shock, creating microscopic cracks in the silicon cells that ruin panel efficiency.

Engineering Care

The Solabrix module washing standard.

We don't take shortcuts. Every single module wash follows strict technical protocols executed by trained technicians equipped with specialized gear.

1. Early Morning Scheduling

Thermal Shock Prevention

We wash panels early in the morning when ambient temperatures are low and modules are cool. This completely eliminates the risk of thermal shock micro-fractures in silicon cells.

2. On-Site Water TDS Testing

Zero Mineral Calcification

Our technicians test your rooftop water with digital TDS meters. We employ low-mineral rinse techniques to ensure hard borewell water never leaves stubborn white calcium scale on your panel glass.

3. Telescopic Soft-Bristle Brushes

Protecting Anti-Reflective Coatings

We use specialized carbon-fiber telescopic poles with solar-grade soft nylon bristles. Dirt, bird lime, and soot are gently loosened without scratching the anti-reflective glass surface.

4. Timestamped Photo Proof on Zenith

Complete Visibility On Your Phone

You don't need to climb a precarious rooftop ladder to check the results. Our team uploads high-resolution before-and-after photos directly to your Solabrix Zenith dashboard.

Housing Societies (CHSs)

Schedule a comprehensive array cleaning before festival seasons or after heavy construction dust storms in your neighborhood to ensure common-area power bills stay minimal.

Commercial Rooftops

Commercial solar systems located near highways or industrial zones accumulate heavy diesel soot and particulate matter. An ad-hoc single wash instantly restores peak megawatt-hour generation.

Frequently Asked Questions

Everything you need to know about Module Washing.

Clear answers on cleaning methods, thermal shock, water chemistry, and safety.

What does a Solabrix Single Module Wash include?

A Solabrix Single Module Wash is a comprehensive on-ground panel cleaning service.

It includes on-site water TDS testing to avoid limescale scaling, gentle washing using specialized telescopic soft-bristle solar brushes, early-morning scheduling to prevent thermal shock micro-cracking, visual inspection for hotspots or physical glass damage, and high-resolution before-and-after photo proof uploaded to your Zenith portal.

Why shouldn't my house maid or car cleaner wash the solar panels?

Informal cleaners cause permanent damage in three ways:

  1. Hard borewell water leaves chalky mineral deposits (calcium and magnesium scale) that bake onto the glass and cannot be washed away by rain.
  2. Washing during sunny afternoons causes severe thermal shock, creating microscopic cracks in the silicon cells.
  3. Abrasive brooms, wipers, or detergent chemicals strip the delicate anti-reflective coating (ARC), permanently lowering light absorption.

Solabrix uses certified techniques and solar-grade equipment to protect your panels' 25-year lifespan.

What is thermal shock and why does cleaning time matter?

Under midday Indian sun, solar panel glass heats up to 60°C–70°C. Spraying room-temperature or cold water onto hot glass causes sudden localized temperature differentials—known as thermal shock.

This can shatter tempered glass or cause micro-fractures in silicon cells that degrade generation permanently. Solabrix schedules washing strictly during early morning hours before panels heat up.

Do technicians test the water quality before washing?

Yes. Our technicians carry digital TDS (Total Dissolved Solids) and pH meters. If water TDS is too high (hard borewell water), it leaves permanent mineral stains that act like permanent shading.

We verify water suitability and employ low-mineral rinse techniques to protect the glass surface.

Do I need to provide water and electricity on the roof?

Yes. Access to a functioning rooftop water tap or outlet and a standard electrical socket is required. Our technicians arrive with all necessary specialized hoses, connectors, telescopic poles, and soft solar brushes.

What safety standards and gear do Solabrix technicians follow?

Technicians strictly follow rooftop safety standards. They wear safety harnesses, lifelines anchored to rigid structural points, non-slip rubber footwear, and helmets.

Homeowners are completely protected from the personal liability risks associated with untrained laborers on wet rooftops.

How much extra generation can I expect after a professional wash?

Depending on soiling severity, location (proximity to construction or major roads), and how long since the last wash, plant owners typically observe a 15% to 30% immediate rebound in daily generation score right after a professional cleaning.

Which areas in Pune are covered for physical module washing?

Currently, our on-ground physical cleaning services are active exclusively in Bavdhan, Kothrud, Warje, Karvenagar, and Erandwane.

We are actively expanding our technician presence to cover more Pune neighborhoods soon.

Note: SolarSaathi digital monitoring and managed care is open to all solar plant owners across all of Pune.

Do SolarSaathi members get discounted wash pricing?

Yes! Active SolarSaathi subscribers receive substantial discounts (up to 20%–25% off) across all capacity tiers for module washes. For example, a 5 kW plant wash costs ₹1,375 for members versus ₹1,625 standard.

Can I upgrade to an Annual Maintenance Contract (AMC) after trying a single wash?

Yes, absolutely.

This is the service to try out before committing to a year-long service relationship. If you buy AMC within one month after this service, we will adjust it towards the cost of AMC. In other words, it won't cost you extra if you buy AMC after this service.
