What Is PM Surya Ghar?
The programme targets 1 crore (10 million) residential rooftop installations by FY 2026-27 (the implementation period runs to 31 March 2027), with a total outlay of Rs 75,021 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 installation vendors registered on the National Portal. Households apply, install, and receive subsidy through the PM Surya Ghar National Portal (pmsuryaghar.gov.in).
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 to 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 vendors registered on the PM Surya Ghar National Portal 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 to 50%. A 3 kW system that costs Rs 1.5 to 1.75 lakh is available for Rs 72,000 to 97,000 after subsidy. This brings solar within reach of households that previously could not afford it.
- Delivers payback in 3 to 5 years. With subsidy and net metering, most residential systems recover their investment within 3 to 5 years, then generate free electricity for 20+ years.
- Locks in long-term savings. Savings depend on your tariff and consumption; the worked example below shows how to estimate them from generation and your per-unit rate.
- Enables bank financing. Collateral-free solar loans (around 7% for systems up to 3 kW at launch) 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: The Government estimated at Cabinet approval that the scheme will create around 17 lakh direct jobs in manufacturing, logistics, sales, installation, O&M and other services.
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 (pmsuryaghar.gov.in) using mobile number and electricity connection details.
- Vendor selection. The consumer selects a vendor registered on the National Portal. 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. Under the Electricity (Rights of Consumers) Rules, applications up to 10 kW are deemed accepted without a technical feasibility approval; until a state operationalises this, the DISCOM checks feasibility as per state regulations.
- Installation and commissioning. The vendor installs the system using DCR modules (Indian modules made from Indian cells) and inverters that meet the scheme’s technical specifications. 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 the DISCOM approves the inspection on the portal, the consumer redeems the e-token and the CFA is processed within 15 days of DISCOM approval. If the system is financed, the CFA goes to the loan account first.
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 to 30,000 = Rs 90,000 |
| Up to 2 kW | Rs 60,000 | Rs 1,60,000 to 60,000 = Rs 1,00,000 |
| 3 kW or larger | Rs 78,000 (maximum) | Rs 1,70,000 to 78,000 = Rs 92,000 |
Subsidy is released to the beneficiary’s bank account (or loan account, if financed) after DISCOM inspection and approval. Group housing societies and RWAs get Rs 18,000/kW for common facilities, up to 500 kW at 3 kW per house.

India-Specific Context
Rollout Status by State
Implementation pace varies significantly by state:
- Gujarat, Maharashtra, Karnataka, Tamil Nadu: Fastest rollout with extensive DISCOM cooperation and many registered vendors. Gujarat is among the leading states for rooftop solar installations.
- Uttar Pradesh, Madhya Pradesh, Rajasthan, Andhra Pradesh: Ramping rollout with state-specific acceleration programmes.
- Northeast states, Bihar, West Bengal: Slower implementation due to administrative capacity constraints and lower solar resource in some areas.
State-Specific Add-On Subsidies
Some states offer additional state-level subsidies on top of the central PM Surya Ghar scheme:
- Under the scheme guidelines, any State/UT top-up must follow the scheme guidelines and is disbursed through the National Portal.
- Whether a top-up exists, and for whom, changes over time; check your state nodal agency or DISCOM before counting on one.
Financing Ecosystem
Public sector banks including State Bank of India, Canara Bank, Punjab National Bank, Bank of Baroda and Indian Bank offer rooftop solar loans, and loan products are listed on the National Portal through Jan Samarth integration. The scheme guidelines envisage low-interest loans near the benchmark rate (repo + 50 bps) for systems up to 3 kW; larger systems are financed at higher rates. Loan limits, rates and tenures change, so confirm them with the bank.
Outside the scheme’s bank loans, households can also use a personal loan or a home-loan top-up; compare its rate with a PSU-bank PM Surya Ghar loan first.
Future Trends
- Battery integration: Future scheme revisions may include partial subsidy for battery storage to improve reliability.
- Virtual and group net metering: The guidelines already make these arrangements CFA-eligible where the state regulator and DISCOM approve them; wider state adoption would open the scheme to more apartment dwellers.
- Digital onboarding: Faster DISCOM integration on the National Portal would shorten timelines.
- 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 registration. Only vendors registered on the National Portal qualify for subsidy.
- Avoid by: Verifying vendor status on the National Portal before signing.
-
Choosing non-DCR or non-ALMM modules. Subsidy is denied if any non-DCR module is used.
- Avoid by: Insisting on DCR certificates, 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 and the scheme’s implementation period runs to 31 March 2027; 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.
