What Is PM Surya Ghar?
PM Surya Ghar Muft Bijli Yojana is the Government of India’s flagship residential rooftop solar subsidy scheme, launched on 13 February 2024. The scheme combines direct Central Financial Assistance (CFA) for solar installation with a free-electricity guarantee for the first 300 units per month to eligible households.
The programme targets 1 crore (10 million) residential rooftop installations by FY 2027, supported by a budget of approximately Rs 75,000 crore. It is the largest single residential solar programme launched in India to date, building on the earlier Phase-II Grid-Connected Rooftop Solar Programme.
The Ministry of New and Renewable Energy (MNRE) is the nodal ministry. Implementation runs through State Nodal Agencies, DISCOMs, and MNRE-empanelled installation vendors. Households apply, install, and receive subsidy through a unified National Portal for Rooftop Solar.
In the solar industry, PM Surya Ghar has transformed the residential rooftop market by reducing the customer acquisition cost barrier. Before the scheme, residential solar adoption was limited to high-income early adopters. With CFA covering 30–50% of system cost, the addressable market has expanded to middle-income households across tier-1, tier-2, and tier-3 cities.
In the Indian context, PM Surya Ghar is part of a broader strategy to reduce DISCOM subsidy burden, improve energy access, and meet India’s 500 GW non-fossil capacity target by 2030. Residential rooftop solar is seen as the “last mile” of the energy transition, decentralised, consumer-owned, and grid-supportive.
Important: Only MNRE-empanelled vendors can install systems eligible for PM Surya Ghar subsidy. Heaven Green Energy is Gujarat’s #1 ranked PM Suryaghar installer with empanelment across all four Gujarat DISCOMs.

Why PM Surya Ghar Matters
PM Surya Ghar is not merely a subsidy, it is a structural intervention that reshapes residential solar economics at scale.
Financial Impact
- Reduces upfront cost by 30–50%. A 3 kW system that costs Rs 1.5–1.75 lakh is available for Rs 72,000–97,000 after subsidy. This brings solar within reach of households that previously could not afford it.
- Delivers payback in 3–5 years. With subsidy and net metering, most residential systems recover their investment within 3–5 years, then generate free electricity for 20+ years.
- Locks in 25-year savings. A typical 3 kW system saves Rs 60,000–90,000 per year, totalling Rs 15–22 lakh over the plant life against an after-subsidy cost of Rs 1.6–1.8 lakh.
- Enables bank financing. Concessional solar loans at 7–9% make the after-subsidy cost affordable through EMI, with electricity savings often covering the EMI itself.
Social Impact
- Energy equity: Middle-income households gain access to clean, reliable power without dependence on erratic grid supply or expensive diesel backup.
- Rural penetration: The scheme extends to rural and semi-urban areas where grid reliability is lower and solar value is higher.
- Job creation: MNRE estimates the scheme will create 10+ lakh direct and indirect jobs in manufacturing, installation, and O&M.
Grid Impact
- Reduces peak load: Distributed rooftop solar injects power during daytime peak, reducing DISCOM procurement costs.
- Defers infrastructure investment: Local generation reduces the need for new transmission and distribution capacity in high-growth areas.
- Improves DISCOM finances: While rooftop solar reduces DISCOM sales volume, it also reduces the subsidy burden on agricultural and residential tariffs.
How PM Surya Ghar Works
The PM Surya Ghar process runs through the National Portal for Rooftop Solar and involves seven key stages:
- Consumer registration. The applicant registers on the National Portal (pmsuryagrh.gov.in) using mobile number, Aadhaar, and electricity bill details.
- Vendor selection. The consumer selects an MNRE-empanelled vendor from the portal’s directory. The vendor conducts a site survey and prepares a technical proposal.
- Feasibility application. The vendor submits a feasibility application to the DISCOM through the portal, including single-line diagram, structural assessment, and proposed system size.
- DISCOM approval. The DISCOM verifies electrical feasibility, transformer capacity, and sanctioned load compliance. This typically takes 15–30 days.
- Installation and commissioning. The vendor installs the system using ALMM-listed modules and MNRE-empanelled inverters. The system is commissioned and a commissioning certificate is uploaded.
- Net metering and inspection. The DISCOM installs the bidirectional net meter and conducts a physical inspection of the installation.
- Subsidy disbursement. After successful inspection, the subsidy is directly credited to the consumer’s registered bank account within 15–30 days.
Total timeline from application to subsidy receipt: 60 to 120 days, depending on DISCOM efficiency and vendor capacity.
The Subsidy Structure
| System Size | Subsidy Amount | Effective Cost (3 kW example) |
|---|---|---|
| Up to 1 kW | Rs 30,000 | Rs 1,20,000 – 30,000 = Rs 90,000 |
| Up to 2 kW | Rs 60,000 | Rs 1,60,000 – 60,000 = Rs 1,00,000 |
| 3 kW or larger | Rs 78,000 (maximum) | Rs 1,70,000 – 78,000 = Rs 92,000 |
| Above 10 kW | Rs 78,000 (capped) | Pro-rata on first 10 kW only |
Subsidy is direct cash transfer to the beneficiary’s bank account after commissioning and inspection. For housing societies and multi-dwelling structures, group housing societies can also avail subsidy with appropriate documentation.

- Green hydrogen linkage: Long-term vision includes using residential solar surplus for small-scale green hydrogen production.
- Carbon credit monetisation: Residential solar generation may become eligible for carbon credit programmes, adding a revenue stream.
Common Mistakes & Misconceptions
-
Applying without confirming vendor empanelment. Only MNRE-empanelled vendors qualify for subsidy.
- Avoid by: Verifying vendor status on the National Portal before signing.
-
Choosing non-ALMM modules. Subsidy is denied for non-ALMM installations.
- Avoid by: Insisting on ALMM list verification and serial number documentation — Heaven Designs’ guide to how the ALMM list affects your BOQ explains what to check.
-
Oversizing beyond sanctioned load. Many states reject applications where solar exceeds sanctioned load.
- Avoid by: Checking sanctioned load on your latest bill before sizing.
-
Skipping DISCOM feasibility. Direct installation without approval voids net metering and subsidy.
- Avoid by: Following the portal process sequentially; never install before feasibility approval.
-
Mismatched bank account name. Subsidy is credited to the registered consumer’s account; name mismatches cause delays.
- Avoid by: Ensuring portal registration name matches bank account and electricity bill.
-
Choosing lowest-cost vendor without checking service. Solar plants have 25-year life and need long-term support.
- Avoid by: Evaluating vendor track record, warranty terms, and after-sales presence.
-
Expecting battery backup from the scheme. PM Surya Ghar does not subsidise batteries.
- Avoid by: Budgeting separately for battery storage if backup is required.
-
Not understanding the 300-unit free electricity claim. This is achieved through net metering, not a separate cash payment.
- Avoid by: Understanding that “free” means offset through generation, not a DISCOM waiver.
-
Delaying application expecting higher subsidy. Subsidy slabs are fixed; delays only reduce the years of savings.
- Avoid by: Applying as soon as your roof and finances are ready.
-
Ignoring maintenance needs. Even subsidised systems need annual cleaning and inspection.
- Avoid by: Signing an AMC with your installer for ongoing O&M.
