Frequently asked.
How long does a typical rooftop install take? +
Most residential systems (5–10 kW) are installed in 2–4 days once permits clear. Industrial systems (500 kW and up) typically take 6–10 weeks from contract signing to commissioning.
What subsidies are available for residential solar? +
Homeowners can claim up to ₹78,000 in central PM Surya Ghar subsidies, plus state-level DISCOM net metering benefits. We handle all the paperwork.
Do you offer financing? +
Yes — we partner with three Indian banks to offer zero-down-payment EMI plans for both households and small businesses, with tenors up to 7 years.
What happens if the system underperforms? +
All our systems come with a 25-year linear power warranty and a 5-year workmanship warranty. If output drops below warranted levels, we replace the modules at no cost.
