Frequently Asked Questions

For homes, expect ₹55,000 – ₹65,000 per kW installed before subsidy. A typical 3 kW home system costs ₹1.65–1.95 lakh, and after the PM Surya Ghar subsidy of ₹78,000, your effective cost is around ₹90,000. Commercial and industrial systems are priced lower per kW due to scale (₹40K–₹50K/kW).

Under the PM Surya Ghar Muft Bijli Yojana, residential customers get ₹30,000 per kW up to 3 kW (₹90,000 max), plus ₹18,000 for the 4th kW — total maximum subsidy is ₹1,08,000 for systems ≥3 kW. For smaller 1–2 kW systems, subsidy is ₹30K–₹60K. The subsidy is transferred directly to your bank account after installation and DISCOM approval.

Yes. We partner with HDFC, SBI, Tata Capital, and local NBFCs for solar loans at 8.5–11% interest, tenure 3–7 years. Many banks offer specific “rooftop solar” loan products with fast approval. Our team will connect you with the right lender based on your profile.

For a typical residential system: 2–3 days for panel installation, plus 2–4 weeks for DISCOM net-metering approval. Total time from order to commissioning: 4–6 weeks. Commercial projects take 6–10 weeks depending on size and DISCOM processing.

For independent houses: no external permission needed. For apartments/societies: RWA approval is needed. For commercial: society/landlord NOC. We help draft all required permission letters and structural feasibility reports as part of our service.

Yes — panels generate even on cloudy days (at 15–40% of peak), and grid-tied systems automatically draw from the grid when generation is low. Annual generation accounts for all weather conditions; our estimates include ~15% derating for monsoon months.

Net metering lets you export surplus solar generation to the grid during the day and import it back at night. You’re only billed for the “net” units consumed. Every DISCOM has a slightly different process — we handle the application, inspection coordination, and final approval for you.

Absolutely. A typical 1.5-ton AC consumes ~1.5 kW. A 3 kW solar system can run 1 AC + lights + fans during the day comfortably. For whole-home AC coverage, we recommend 5 kW+. Our savings calculator shows the right system size for your load.

Tier-1 panels carry a 25-year performance warranty (guaranteeing ≥80% output at year 25) and a 10–12 year product warranty against manufacturing defects. Inverters carry 10-year warranty (extendable to 15). Ojas provides a 2-year workmanship warranty on installation itself.

In most Indian cities, a light rinse every 4–6 weeks is enough. Heavy dust zones (highways, construction areas) need cleaning every 2–3 weeks. Our AMC includes quarterly professional cleaning + thermal imaging. Uncleaned panels can lose 5–10% efficiency.

Panels can be relocated, though cost is ~₹8,000–₹15,000 for dismantling, transport, and reinstallation. Many homeowners leave the system and factor the solar-enabled lower bills into the sale price (typically recovers 60–80% of system cost in resale value).

Panels: 25–30 years with gradual performance degradation (loses ~0.5% output per year). Inverters: 10–15 years (replaced once in system lifetime). Complete system ROI horizon: 25 years; after 5–7 year payback, you get 18–20 years of essentially free power.
