How PM Surya Ghar Scheme Works 2026

The PM Surya Ghar Muft Bijli Yojana is the primary vehicle for India's energy transition. In 2026, the scheme continues to provide a direct bank transfer of up to ₹78,000 for residential households. The subsidy is strictly linked to DCR (Domestic Content Requirement), meaning your solar panels must be manufactured in India to qualify for the grant.

The process is fully digitized via the National Portal. Once your vendor uploads the commissioning report and the net-meter is installed, the MNRE verifies the data and pushes the subsidy into your Aadhaar-linked bank account within 15 to 20 days.

Deep-Dive: Net Metering vs Gross Metering

Net Metering is the gold standard for residential solar in 2026. It allows you to offset your electricity bill unit-for-unit. If your house consumes 300 units but your solar generates 300 units, your 'Energy Charge' becomes zero. You only pay fixed meter rent.

Gross Metering is often used for commercial setups where all solar power produced is sold to the Discom at a fixed low tariff, while you buy back power at a high consumer rate. For homeowners, always prioritize Net Metering to maximize ROI.

Solar Rooftop FAQ (2026 Edition)

Can I take a collateral-free loan for solar in 2026?
Yes. Under the PM Surya Ghar scheme, banks like SBI offer the "Surya Shakti" loan. For systems up to 3kW, you can get collateral-free financing at interest rates around 7% (tied to the repo rate).
How long does it take for the subsidy to hit the bank account?
Once the Discom finishes net-metering and the commissioning certificate is uploaded to the National Portal, the subsidy typically arrives via DBT within 15 to 20 business days.
Are there additional state-level subsidies?
While the PM Surya Ghar is a Central scheme, states like Gujarat (Surya Gujarat) and Uttar Pradesh occasionally offer extra top-up subsidies or lower registration fees. However, most homeowners find the ₹78,000 Central grant sufficient.
Is DCR mandatory for the subsidy?
Yes. Domestic Content Requirement (DCR) is mandatory for residential subsidies. This means the solar cells and modules used in your installation must be manufactured within India.
What documents are required for application?
You primarily need: 1. Latest Electricity Bill, 2. Aadhaar Card, 3. Bank Account details (with cancelled cheque), and 4. A photograph of the rooftop space.
