Rooftop Solar & Net-Metering FAQs

Under PM Surya Ghar Muft Bijli Yojana, residential individual homeowners receive a direct Central Financial Assistance (CFA) subsidy of ₹30,000 for a 1 kW system, ₹60,000 for a 2 kW system, and a flat ₹78,000 for all systems of 3 kW capacity and above. Group Housing Societies (GHS) and Resident Welfare Associations (RWAs) qualify for ₹18,000 per kW for common area utilities (up to 500 kW). Maxira Solar handles the complete registration on the National Solar Portal, ensuring DBT subsidy credits reach your bank account within 30 days of DISCOM commissioning.
Net metering enables automated bidirectional energy accounting with your local distribution utility (such as MPMKVVCL, MPPKVVCL, MSEDCL, or JVVNL). During daytime hours, your rooftop solar plant powers your building, and surplus electricity is exported to the grid. At night, you draw power from the grid. At the end of each billing cycle, your DISCOM credits exported solar units against imported units, charging you only for the net difference.
All Maxira Solar systems use Tier-1 TOPCon bifacial solar modules backed by a 25-year linear performance warranty (guaranteeing >84.8% power output at year 25) and a 10–12 year product defect warranty, along with 5–10 years on smart string inverters and a 25-year structural warranty on hot-dip galvanized mounting superstructures.
A 1 kW solar system requires approximately 80 to 100 sq.ft of shadow-free rooftop area. A 3 kW system requires 250 to 300 sq.ft, and a 5 kW system requires 400 to 500 sq.ft. Maxira Solar also designs elevated pergola superstructures (with 7 to 9 feet clearance) that preserve 100% of the usable terrace floor space for gardening, recreation, and clothes drying.
Yes. On-grid solar systems sync seamlessly with the utility grid to effortlessly power heavy inductive household loads—including 1.5-ton 5-star inverter air conditioners, 1 HP to 3 HP submersible water pumps, geysers, induction cooktops, and Electric Vehicle (EV) home fast chargers—with zero voltage drops or power interruptions.
Rooftop solar systems require minimal maintenance because they have no moving mechanical parts. Rinsing the modules with clean water every two weeks to remove surface dust ensures peak energy harvest. Maxira Solar also includes automated 24/7 IoT telemetry monitoring and annual preventative maintenance audits in our EPC contracts.
Modern monocrystalline TOPCon bifacial panels generate electricity even under diffuse atmospheric light during monsoon overcast conditions, typically producing 35% to 65% of their peak rated capacity. In winter, clear sunny skies and cooler ambient temperatures actually enhance silicon cell efficiency by 4% to 7%.
No. On-grid solar systems do not require batteries because the public utility grid acts as a virtual 100% efficient battery storage via net metering. Eliminating batteries reduces capital costs by ₹1.2 to ₹2.0 Lakhs and avoids recurring battery replacements every 5 to 7 years.
Under Section 32 of the Income Tax Act, commercial enterprises, hospitals, hotels, and factories can claim 40% Accelerated Depreciation on solar capital assets in the first year of operation, lowering corporate income tax liability and recovering up to 25% of project cost in immediate tax savings.
Through our banking partnerships with State Bank of India (Surya Ghar Loan Scheme), Canara Bank, and leading NBFCs, homeowners can access collateral-free solar loans with interest rates as low as 7.0% p.a., zero upfront down payment, and flexible EMI tenures up to 5 to 7 years.
For residential on-grid systems, after deducting the ₹78,000 PM Surya Ghar subsidy, the total capital investment is fully recovered within 3.5 to 4.5 years through electricity bill savings. Over its 25-year lifespan, a 3 kW system yields over ₹12 to ₹15 Lakhs in net cumulative power savings.
