Sisphyus
For home solar owners

Your home solar panels are probably dirty right now.

At 15% soiling on a 5 kWp Rajasthan rooftop, you're losing ~₹7,875/year in generation. We fix that.

Estimate: 5 kWp × 1,500 kWh/kWp/yr × 15% soiling × ₹7/kWh ≈ ₹7,875.

5 kWp
You may be losing
₹10,800 / year

Estimate — ₹8/kWh residential tariff, 1,500 kWh/kWp/yr generation baseline, 18% typical soiling for Rajasthan.

Why residential cleaning is hard

Cleaning once a month means panels are dirty 27 days out of 30.

Manual cleaning uses 5L per panel — expensive if you're on a water meter.

Reaching rooftop panels safely without professional gear is a real risk.
