Solar Rooftop – Frequently Asked Questions

• ₹30,000 for 1 kW
• ₹60,000 for 2 kW
• Up to ₹78,000 for systems from 3 kW to 10 kW

The subsidy scheme is designed mainly to support middle-class and lower-income households. Full subsidy benefits apply only up to 3 kW. Systems above 3 kW are eligible only up to ₹78,000.

No. In an on-grid solar system, the inverter automatically shuts down when grid power fails. This is a mandatory safety feature.

Yes. Appliances like AC, refrigerator, geyser, washing machine, and lights work normally. Solar power output is the same 230V as grid electricity.

• Electricity bill can reduce to almost ₹0
• Net-metering benefit
• Government subsidy eligibility
• Very low maintenance
• Payback in 3–5 years

A 3 kW system generates about 350–400 units per month. If your bill is ₹2,000–₹3,000, it can reduce to nearly zero.

Most RCC roofs are suitable. The roof should be shadow-free and structurally strong. Site inspection confirms feasibility.

• 1 kW – 90 to 100 sq. ft.
• 3 kW – 270 to 300 sq. ft.
• 5 kW – 450 to 500 sq. ft.

South-facing panels generate maximum power in India. East-West orientation also works efficiently.

No. Panels are mounted with special structures and waterproofing to protect roof integrity.

Yes. Special mounting structures are used. Cost and design may vary.

Yes, but with reduced output. Solar panels do not generate power at night.

Yes. Monthly cleaning with water helps maintain efficiency.

Extra power is exported to the grid through net metering and adjusted in your electricity bill.

A bi-directional net meter records imported and exported electricity separately.

• Panels: 25–30 years
• Inverter: Up to 7 years
• Workmanship: 5 years

Note: Physical glass damage is not covered.

Yes. Loans up to 90% are available at approx. 6.5–7% interest with 3, 5, or 10-year tenure. Subsidy can be adjusted against the loan.

Yes. Upgrades are possible if roof space and load allow. Shifting to a new location requires new approvals.

Yes. With rising electricity tariffs, solar is one of the best long-term investments.
