Ultimate Guide: How to Claim Your Government Solar Subsidy in India
Transitioning to clean solar energy is one of the most profitable investments an Indian family can make. To make residential installations highly affordable, the Central Government has launched the **PM-Surya Ghar Muft Bijli Yojana**, backed by a massive budget of ₹75,021 Crores. Our Solar Subsidy Calculator India calculates your exact eligible grant amount in Rupees, fully synchronized with the official Ministry of New and Renewable Energy (MNRE) guidelines.
1. Detailed Sizing of PM-Surya Ghar Subsidy Brackets
The central financial assistance (subsidy) is directly linked to the physical capacity of your solar plant in Kilowatts (kW). Sizing has a highly progressive sliding scale designed to heavily support standard middle-class homes:
- Systems Up to 2 kW Sizing: You receive a high subsidy of **₹30,000 per kW**. For example, a 1 kW plant receives a ₹30,000 grant. A 2 kW plant receives a flat **₹60,000** subsidy.
- Systems Between 2 kW and 3 kW Sizing: Sizing receives an incremental subsidy of **₹18,000 per kW** for the third kilowatt. For a 3 kW system, the total subsidy is calculated as:
₹60,000 + ₹18,000 = ₹78,000. - Systems Above 3 kW Sizing: The central financial subsidy is strictly **capped at a maximum of ₹78,000**. If you choose to install a larger 5 kW, 8 kW, or 10 kW system to run multiple high-load appliances (like air conditioners and geysers), the central subsidy remains capped at ₹78,000.
2. Sizing Additional State-Specific Grants
Several progressive state governments are determined to accelerate rooftop solar adoption by adding their own state-level incentives on top of the central grant:
- Surya Gujarat Scheme: Gujarat offers a highly efficient solar policy that adds flat state incentives, making residential solar ROI in Gujarat the fastest in the country.
- Delhi Solar Policy: Delhi has introduced a generation-based incentive (GBI). Homeowners receive ₹3.0 per kWh Unit generated by their system, which is credited monthly directly to their bank account, in addition to electricity tax exemptions.
- UP Solar Subsidy: Uttar Pradesh provides a state-specific cash grant of ₹6,000 per kW (up to a maximum of ₹30,000), which directly reduces the initial out-of-pocket costs for families.
3. Step-by-Step Registration and Application Manual
To claim your subsidy successfully, you must follow the official government guidelines step-by-step:
| Phase | Step Description | Portal Action | Estimated Sizing Timeline |
|---|---|---|---|
| Phase 1: Registration | Register on the National Portal for Rooftop Solar (pmsuryaghar.gov.in) using your consumer account number and mobile. |
Select your local DISCOM utility provider and upload your recent bill. | Instant |
| Phase 2: Feasibility check | Apply for a Technical Feasibility approval from your local power company. | DISCOM engineers inspect if your grid transformer can handle the solar load. | 7 to 10 Days |
| Phase 3: Installation | Select an officially empanelled vendor and complete physical installation of panels and inverters. | Empanelled installers ensure standard materials conform to MNRE safety rules. | 3 to 5 Days |
| Phase 4: Net-metering | Apply for bi-directional net-meter setup and grid commissioning. | DISCOM installs the Net Meter and issues a commissioning certificate. | 10 to 14 Days |
| Phase 5: DBT payout | Submit your bank details and commissioning certificate on the National Portal. | The central grant is sent via Direct Benefit Transfer (DBT) to your bank account. | 30 Days |
4. The Importance of Net-Metering in Sizing Returns
Net-metering is the cornerstone of a highly profitable grid-tied residential solar rooftop plant. Your bi-directional net meter acts as a bank account for electricity. During hot summer middays when your solar array produces peak outputs that exceed active household consumption, the excess kWh is exported directly to the grid. At night when the panels are inactive, your home imports power from the grid. At the end of the billing cycle, your local power company computes your net consumption. If you exported more Units than you imported, your bill is zero, and the excess units are carried forward as financial credits to next month's statement.
5. Frequently Asked Sizing Questions (FAQs)
The central subsidy is structured on a progressive capacity sizing scale: a fixed ₹30,000 per kW for the first 2 kW of capacity, and an additional ₹18,000 per kW for the 3rd kW of capacity, supporting residential adopters heavily.
The central financial assistance (grant) is strictly capped at a maximum of ₹78,000 for any residential solar system equal to or greater than 3 kW capacity. Commercial, industrial, or off-grid installations do not qualify.
Register on the official National Portal pmsuryaghar.gov.in using your mobile and consumer number, apply for a feasibility check, choose an empanelled vendor for installation, complete commissioning, and submit your bank details for DBT.
No. The PM-Surya Ghar subsidy scheme is reserved exclusively for residential domestic meters. Commercial, industrial, and institutional users do not qualify for direct grants but are eligible for commercial tax benefits like accelerated depreciation.
Once physical installation is completed, DISCOM grid commissioning verified, and your bank details submitted on the National Portal, the DBT grant is processed and transferred directly to your bank account within 30 days.
