Your panels are losing
₹ crore every year.
We show you exactly how much.
Dust soiling silently cuts solar output by up to 25%. SolarWatch monitors your farms using orbital imaging and converts every soiling signal into estimated rupee revenue loss — automatically, every few days, without sensors or site visits.
The hidden cost
India's solar farms are losing ₹18,000 Crore every year — invisibly.
Dust and particulate matter coat solar panels continuously. On a clean day, soiling cuts output by 3–5%. After a major dust event — up to 25%. The loss compounds daily between cleanings. Most farms discover it months later, during a site audit, by which time the damage is done.

Every row accumulates dust differently — panel tilt, wind direction, and row position all affect soiling gradient across a farm.
From guesswork to verified intelligence
Most solar farms still rely on quarterly site visits. Months of losses accumulate — undetected, unquantified, unjustifiable.
Without continuous monitoring
- Quarterly site audits — soiling undetected for 90+ days
- No ₹ translation — hard to justify cleaning costs to management
- Excel-based tracking — no pattern analysis or early warning
- No advance notice before dust events arrive
- Every farm gets the same cleaning schedule regardless of actual soiling
With SolarWatch
- Automated imaging every few days — soiling caught in days, not quarters
- Exact ₹ crore loss per farm — prioritize cleaning by revenue impact
- 5-day dust event forecast — schedule cleaning before it hits
- Automated urgency flags: PLAN / URGENT / CRITICAL per farm
- Portfolio-level dashboard — one view for all farms across all states
No sensors. No site visits.
How it works
Share your farm location and capacity. We do everything else — data ready in 48 hours.
Register your farm
Share your farm location, state, and installed capacity in MW. We map your panel layout and establish your clean baseline from the first imaging pass after your last wash.
We monitor automatically
Our system pulls current imaging and atmospheric data for your farm every few days — orbital imaging, thermal scanning, and dust forecasts — fully automated. Zero action needed from you.
You get ₹ revenue reports
Soiling index, thermal anomaly alerts, and dust forecasts are combined and converted to estimated rupee loss per year — visible on your dashboard and as email alerts.
Built for India's solar value chain
From independent power producers to O&M teams and project lenders — every stakeholder has a different question. SolarWatch answers all of them in ₹.
IPPs & Asset Owners
Know your ₹ exposure before the auditor does
Get a consolidated view of soiling losses across your entire portfolio. Understand the exact revenue impact of every day you defer cleaning.
Portfolio-level ₹ exposure in one view
O&M Contractors
Dispatch crews based on data, not guesswork
Stop sending teams to farms that don't need cleaning. Let data-driven soiling scores direct your workforce to the highest-value work.
Reduce unnecessary cleaning trips by 30–40%
Project Lenders & Advisors
Soiling risk affects IRR — now you can quantify it
Independently verified soiling reports provide an ongoing performance baseline — ideal for due diligence, covenant monitoring, and green refinancing.
Independent verified performance record
Every signal your farm needs
Multiple data sources. One integrated dashboard. Every metric translated to ₹.
Panel Soiling Detection
Orbital imaging measures reflectance change across your panel surface against your post-cleaning baseline. Detects 3–25% generation losses on a recurring cadence.
Thermal Anomaly Detection
Thermal imaging flags hot-spot clusters — panels running significantly above the farm average temperature. Catch cell faults and connection defects before they cascade.
5-Day Dust Event Forecast
Atmospheric monitoring tracks incoming dust fronts across India. Urgency escalates before an extreme event — so you clean before the storm, not after.
Revenue Impact in ₹
Every soiling signal is converted using your capacity, utilisation factor, and PPA tariff rate. The headline metric is always ₹ crore / year — never an abstract 0–100 index.
Cleaning ROI Calculator
Compare cleaning cost against expected revenue recovery. See the exact payback period before dispatching crews — prioritize by financial ROI, not by a fixed rotation schedule.
