What Is PM Surya Ghar?

What is PM Surya Ghar?

PM Surya Ghar Muft Bijli Yojana is the residential rooftop solar scheme announced by the Government of India on 29 February 2024. It replaces the older MNRE Phase II subsidy programme with a higher per-kW grant, a tied concessional loan, and a single National Portal that links the applicant, the DISCOM, the empanelled installer, and the bank into one workflow. The headline promise is one crore solar homes by 2027 and up to 300 units of free monthly electricity for participating households.

The subsidy structure is fixed at the central level: ₹30,000 for the first 1 kW, ₹60,000 for 2 kW, and ₹78,000 for any system of 3 kW or larger. Above 3 kW the consumer pays full project cost for the extra capacity. Some states top up the central subsidy with their own grant. Gujarat, for example, has historically added a state contribution for residential rooftop, though the exact rate changes with each financial year notification.

The scheme is not just a cheque. It bundles four levers that previously had to be navigated separately: capital subsidy, low-interest loan, net-metering approval, and standardised installer empanelment. For the homeowner that means one form, one tracking dashboard, and a single point of escalation. For an EPC it means the policy and execution risk both sit on the National Portal, not on the customer's living-room conversation.

Why does PM Surya Ghar matter?

Until 2024, residential rooftop solar in India ran on Phase II subsidies that were inconsistent across states, slow to disburse, and tied to DISCOM cooperation that varied by district. PM Surya Ghar collapses that variability into a single national workflow. For a household considering a 3 kW system at roughly ₹1.8 lakh project cost, the ₹78,000 subsidy plus the loan lever drops effective payback from 7 to 8 years down to 3 to 4 years.

For solar EPCs and installers, the scheme is now the single largest residential demand-generation channel. Surat-based installers report that 70 percent of new residential enquiries in 2025 mention the scheme by name before quoting starts. An EPC not empanelled on the National Portal in their district is effectively invisible to that traffic.

For DISCOMs, the scheme transfers some pressure from net-metering policy to capacity buildout. State commissions that had been gradually shrinking residential net-metering caps now face central pressure to keep them open up to at least the 3 kW subsidy threshold.

For policy, PM Surya Ghar is the test bed for whether large-scale subsidised residential solar can sustain itself once the capital grant lapses. The bet is that 25-year tariff savings plus a concessional EMI will create enough demand to keep installers busy after central money tapers in 2027.

How does PM Surya Ghar work, step by step?

1. Register on the National Portal. The consumer visits pmsuryaghar.gov.in, enters DISCOM and consumer number, links Aadhaar, and uploads basic property details.
2. DISCOM feasibility check. The local DISCOM runs an LT-feeder and transformer capacity check. If the local infrastructure can absorb the export, approval moves forward. If not, the application is parked or downsized.
3. Pick an empanelled installer. The portal lists installers approved for that district. The consumer selects one, gets a quote, and accepts.
4. Optional loan application. The consumer applies for the concessional loan with a partner bank through the same portal. The effective interest rate sits around 7 percent at the time of writing.
5. Installation. The empanelled EPC executes the work using ALMM-listed modules and inverters that meet the Domestic Content Requirement. Typical work takes one to three days for a residential 3 kW system.
6. DISCOM inspection and net-metering. The DISCOM inspects the installation, installs a bi-directional energy meter, and signs the net-metering agreement.
7. Commissioning certificate. The DISCOM uploads the certificate to the National Portal.
8. Subsidy disbursement. The central subsidy is paid directly into the consumer's Aadhaar-linked bank account, typically within seven to fifteen working days of the certificate upload.

The whole cycle takes 30 to 90 days. Active states such as Gujarat, Maharashtra, and Tamil Nadu complete it closer to 30. States with DISCOM backlog can stretch past 90.

Real example: a Surat household

Situation. Mehul Shah lives in Surat with a monthly electricity bill of around ₹3,200 on a 5 kW sanctioned connection under DGVCL. Average monthly consumption is 380 units.

Choice. His installer recommends a 3 kW rooftop system that will roughly match his annual consumption. Project cost: ₹1,85,000 plus GST. PM Surya Ghar subsidy: ₹78,000. State of Gujarat top-up at the time of his application: an additional small grant under the state policy. Net outlay before loan: about ₹1,00,000.

Loan. Mehul takes a ₹90,000 loan at 7 percent over 5 years. EMI is roughly ₹1,780. His expected post-solar grid bill is around ₹350 a month (fixed charges, demand charge, electricity duty, meter rental). Net monthly outflow during the loan period: ₹2,130. After loan closure (year 6 onward), monthly outflow drops to ₹350.

Result. Mehul's payback period under the scheme is roughly 3 years on net cash outflow. Over 25 years, lifetime savings cross ₹6 lakh. Without PM Surya Ghar, the same system would have paid back in 6 to 7 years with about 30 percent lower lifetime savings.

Benefits of PM Surya Ghar

• Direct cash subsidy up to ₹78,000 paid into the bank, not as bill credit, so the homeowner sees the money.
• Concessional loan at around 7 percent on residential rooftop, no collateral required for systems up to 3 kW.
• Single national workflow on pmsuryaghar.gov.in. Replaces the previous patchwork of state portals and DISCOM offices.
• Empanelled installer list per district, reducing the risk of unverified vendors quoting unrealistic numbers.
• 300 units of free monthly electricity for households that pick the recommended system size for their consumption.
• Net metering bundled in. Subsidy is conditional on commissioning the net meter, so the export pathway is locked in by design.
• Loan EMI usually below pre-solar bill. Most households report cash-flow positive within the first month of operation.
• Property value uplift. Resale data from Gujarat and Maharashtra suggests a 3 to 5 percent premium for net-metered solar homes.

Limitations and challenges

Capacity cap at 3 kW for subsidy. Above 3 kW the consumer pays full price for the extra capacity. Households with higher consumption (centralised AC, electric vehicles) usually want 5 to 6 kW, where the marginal economics are weaker.

DCR module pricing. The DCR requirement keeps Indian module manufacturing afloat but typically costs the consumer 10 to 18 percent more than imported alternatives. The subsidy offsets most of that gap, but it does compress installer margin if quote competition is heavy.

DISCOM bottleneck. The portal moves only as fast as the local DISCOM. In states with weak rooftop-solar capacity, applications stack up at the feasibility-check stage.

Loan KYC friction. Bank partners require standard documentation. Co-applicants and self-employed applicants without recent ITRs report delays.

Installer quality varies. Empanelment is procedural, not a quality guarantee. Choose installers with at least 50 commissioned residential projects in your district.

Subsidy is not guaranteed forever. The scheme runs until 2027 as currently notified. Whether the central grant continues at the same rate beyond that date is a policy decision that has not been made yet.

Above 10 kW, net-metering may not survive. Several states have moved larger residential and commercial consumers to net billing. PM Surya Ghar protects the sub-3 kW residential consumer, not commercial or industrial loads.

PM Surya Ghar in India: state-by-state notes

The central scheme is uniform, but execution speed and state top-ups vary. Selected highlights at the time of writing:

State	Key feature	Typical cycle time
Gujarat	Strong state top-up (varies by year), aggressive empanelment, DGVCL/MGVCL/UGVCL/PGVCL handle approvals fast	30 to 45 days
Maharashtra	MSEDCL handling the bulk of applications, residential cap up to sanctioned load, fast meter installation in metro circles	40 to 60 days
Tamil Nadu	TANGEDCO has integrated the scheme with state subsidy stack, paperwork heavy but reliable disbursement	45 to 75 days
Delhi	Three DISCOMs (BRPL, BYPL, TPDDL) on the portal, group net-metering allowed for housing societies	45 to 60 days
Karnataka	BESCOM is selective above 10 kW; below the subsidy cap the workflow is smooth	45 to 60 days
Uttar Pradesh	UPPCL has scaled empanelment in 2025, residential disbursement now competitive with western states	60 to 90 days
Rajasthan	RVPN and Jaipur, Jodhpur, Ajmer Vidyut handle residential. Solar density in semi-urban districts is high	45 to 75 days

Most state SERCs have aligned their residential net-metering regulations with the scheme's 3 kW threshold. A few have raised it. None have published a formal plan to shrink it before 2027.

Common mistakes about PM Surya Ghar

1. Thinking the cash subsidy is paid upfront. It is reimbursed after commissioning. The household funds the work first, the subsidy lands in the bank account after the DISCOM signs off.
2. Picking an installer who is not empanelled in your district. Subsidy is tied to portal-listed installers. A cheaper non-empanelled quote disqualifies the application.
3. Oversizing past 3 kW expecting more subsidy. The subsidy caps at ₹78,000. The fourth kW gets no central grant.
4. Skipping the net-metering step. Without the DISCOM-issued commissioning certificate, the portal never releases the subsidy.
5. Assuming all DISCOMs move at the same pace. Western and southern states clear faster than central or eastern states on average.
6. Quoting "300 units free" as guaranteed. It depends on consumption pattern and system sizing. A household that consumes 600 units a month with 3 kW solar will not get 300 free units; it offsets less.
7. Confusing PM Surya Ghar with PMKUSUM. Surya Ghar is residential rooftop. PMKUSUM is for agricultural pumps and farm-mounted solar. Different audience, different rules.
8. Treating the loan as optional fine print. The concessional loan is what makes the cash-flow story work for most households. Skipping it because of bank-paperwork friction means the homeowner ends up funding from savings, with worse net present value.
9. Forgetting that the meter and inspection fee are payable. The DISCOM charges for the bi-directional meter and the test. Subsidy does not cover that.
10. Assuming roof shading or orientation does not matter. The empanelled installer should reject a roof with major shading. If the system is undersized for the roof actually available, you cannot claim the full subsidy slab.

Key takeaways

• PM Surya Ghar is a central residential rooftop solar scheme launched February 2024, running through 2027.
• Capital subsidy: ₹30,000 to ₹78,000 for systems up to 3 kW. Above 3 kW you pay full price for the extra capacity.
• Concessional loan at around 7 percent makes the cash-flow story work for most households.
• Net metering is mandatory. The DISCOM controls the timeline.
• Only ALMM modules and DCR-compliant equipment qualify. Empanelled installers only.
• Typical cycle 30 to 90 days. State performance varies widely; pick installers with district track record.
• Sub-3 kW residential is the protected zone. Above that, regular state net-metering or net-billing rules apply.
