Energy poverty in India wears two faces. The first is visible — villages and urban slums where grid electricity arrives for only a few hours daily, where power cuts disrupt children’s studies, where refrigerators and fans remain luxury aspirations for families paying monthly bills they can barely afford. The second is less discussed but equally consequential — the household that has a grid connection and receives regular power but spends a disproportionate share of its monthly income on electricity bills that climb with every tariff revision, leaving less for nutrition, education, and healthcare. Both faces of energy poverty share a common solution that was, until recently, financially inaccessible for most Indian households: rooftop solar energy.
A solar panel system installed on a household’s rooftop converts sunlight into electricity that directly powers the home, reducing or eliminating the monthly electricity bill while simultaneously contributing surplus power back to the grid in exchange for compensation. For a household consuming 200 to 300 units monthly, a properly sized rooftop solar installation can reduce the electricity bill to near zero and generate additional income through grid export — transforming the household from a passive energy consumer into an active, compensated energy producer.
The barrier has always been the upfront cost. A 1-kilowatt rooftop solar system costs approximately ₹60,000 to ₹75,000 installed — an amount that places it beyond the reach of economically weaker households without substantial government subsidy. India’s free and subsidised solar schemes — most significantly the PM Surya Ghar Muft Bijli Yojana launched in February 2024 and the PM-KUSUM scheme targeting the agricultural sector — address this barrier with direct financial subsidies that cover the majority of installation cost, making solar access a realistic near-term possibility for crores of households and farmers across the country.
PM Surya Ghar Muft Bijli Yojana: The Flagship Rooftop Solar Programme
Launched by the Government of India in February 2024 with a total outlay of ₹75,021 crore, the PM Surya Ghar Muft Bijli Yojana is the most ambitious residential rooftop solar programme ever undertaken in India. Its stated target — installing rooftop solar systems in 1 crore households by March 2027 — represents a transformational scale of clean energy deployment that would make India’s residential solar programme one of the largest in the world:
| PM Surya Ghar Parameter | Details |
|---|---|
| Scheme Launch | February 2024 |
| Total Financial Outlay | ₹75,021 crore |
| Target Households | 1 crore households with rooftop solar installation |
| Free Electricity Promise | 300 units of free electricity per month for qualifying households |
| Subsidy for 1–2 kW System | ₹30,000 per kW — up to ₹60,000 for 2 kW system |
| Subsidy for 2–3 kW System | ₹18,000 per kW for the additional capacity above 2 kW |
| Maximum Central Subsidy | ₹78,000 for a 3 kW system — covering approximately 40–60% of total installation cost |
| Concessional Loan | Collateral-free loan at a concessional interest rate for the balance of the installation cost |
| Net Metering Benefit | Surplus electricity exported to the grid is compensated through the electricity bill credit |
| Target Beneficiary Profile | Residential households — especially EWS and lower middle class |
| Implementation Agency | State DISCOMs and empanelled solar vendors |
The 300 units of free electricity per month promise is calibrated to the consumption profile of a household with an approximately 2–3 kW rooftop system — a size sufficient to power LED lighting, fans, a refrigerator, television, and basic kitchen appliances throughout the day, effectively eliminating the electricity bill for a household with moderate consumption patterns.
Central Subsidy Structure: What the Government Actually Pays
The financial architecture of PM Surya Ghar’s subsidy is structured to maximise benefit delivery to smaller, economically weaker households while tapering support for larger, higher-capacity installations:
| System Capacity | Central Government Subsidy | Approximate Total Installation Cost | Household Net Cost After Subsidy |
|---|---|---|---|
| 1 kW Rooftop System | ₹30,000 | ₹65,000–₹75,000 | ₹35,000–₹45,000 |
| 2 kW Rooftop System | ₹60,000 | ₹1,20,000–₹1,40,000 | ₹60,000–₹80,000 |
| 3 kW Rooftop System | ₹78,000 | ₹1,75,000–₹2,10,000 | ₹97,000–₹1,32,000 |
| Above 3 kW System | ₹78,000 (capped) | Higher based on capacity | Higher net cost — subsidy capped |
The subsidy tapering above 3 kW discourages oversized installations by wealthier households seeking to maximise grid export income, ensuring that the ₹75,021 crore programme fund is directed primarily toward the EWS and lower middle-class households whose electricity bill burden is proportionally most significant.
PM-KUSUM Scheme: Solar Energy for India’s Farming Households
While PM Surya Ghar addresses residential rooftop solar, the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) scheme targets India’s agricultural sector — providing farmers with solar-powered irrigation pumps and decentralised solar energy generation to reduce their dependence on costly diesel irrigation and unreliable grid power:
| PM-KUSUM Component | Purpose | Subsidy Structure |
|---|---|---|
| Component A | Installation of decentralised grid-connected renewable energy plants on barren or fallow land | 30% central subsidy + 30% state subsidy — farmer contributes 40% or takes a loan |
| Component B | Standalone solar agriculture pumps replacing diesel pumps | 30% central subsidy + 30% state subsidy — farmer pays 40% or takes concessional loan |
| Component C | Solarisation of existing grid-connected agriculture pumps | 30% central subsidy + 30% state subsidy — farmer pays balance |
| Total Government Support | Combined central and state subsidy | 60% of system cost covered — farmer’s net cost 40% |
| Income Generation | Excess solar power is sold to DISCOM at a predetermined tariff | Additional annual income of ₹60,000–₹1 lakh for farmers with Component A |
For a farmer paying ₹50,000 to ₹80,000 annually on diesel for irrigation pumping, the conversion to a solar pump under PM-KUSUM eliminates that recurring expenditure entirely — generating a payback on the farmer’s 40% capital contribution within three to five years while providing effectively free irrigation for the remaining lifespan of the system.
State-Level Solar Subsidy Programmes: Additional Support
Several state governments have layered additional subsidies on top of the central PM Surya Ghar framework, making the effective household cost even lower for beneficiaries in these states:
| State | Additional State Subsidy | Effective Total Subsidy | Net Household Cost (3 kW) |
|---|---|---|---|
| Gujarat | 10–20% additional state subsidy on installation cost | Up to 70% total | Significantly below the national average |
| Rajasthan | State adds 25–40% subsidy for BPL and EWS households | Up to 75% for BPL | Nominal cost for the poorest households |
| Uttar Pradesh | Additional subsidy for rural rooftop installations | Up to 65% total | Reduced from the national average |
| Maharashtra | State augments subsidy for housing society installations | Up to 60% for cooperative housing | Particularly suited to urban apartment blocks |
| Tamil Nadu | State subsidy for government employees and rural households | Up to 65% total | Lower net household cost |
| Andhra Pradesh | APEPDCL additional support for residential consumers | Up to 65% combined | Competitive net cost |
| Madhya Pradesh | CM Solar scheme adds state component | Up to 60–70% for eligible households | Reduced household burden |

Step-by-Step Application Process
Step 1 — Portal Registration: Visit the official PM Surya Ghar portal and register using your Aadhaar-linked mobile number with OTP authentication. Create a beneficiary profile, entering the state, DISCOM, consumer account number, and personal details.
Step 2 — Feasibility Assessment: The portal runs an automated feasibility check based on your electricity consumption history (from DISCOM records via consumer number) and recommends an appropriate system capacity — typically 1 kW for households consuming under 150 units monthly, 2 kW for 150–300 units, and 3 kW for above 300 units.
Step 3 — Vendor Selection: Select an empanelled solar installation vendor from the list of approved vendors in your district displayed on the portal. Empanelled vendors have been vetted by the government for technical capability, pricing compliance, and warranty commitment.
Step 4 — Installation and Inspection: The selected vendor installs the rooftop solar system. The DISCOM conducts a technical inspection of the installation to verify compliance with specifications and net metering requirements.
Step 5 — Net Metering Agreement and Commissioning: After successful inspection, the DISCOM installs a bidirectional net meter and signs the net metering agreement. The system is formally commissioned — from this date, solar generation begins offsetting electricity consumption and any surplus is credited.
Step 6 — Subsidy Disbursement: Upon commissioning confirmation, the central government subsidy is credited directly to the beneficiary’s Aadhaar-linked bank account through Direct Benefit Transfer — typically within 30 days of system commissioning.
Financial Returns: What a Solar Installation Earns Over Its Lifetime
The financial case for PM Surya Ghar participation is compelling even after accounting for the household’s net contribution beyond the subsidy:
| Financial Parameter | Estimated Value |
|---|---|
| Monthly Electricity Bill Saving (2 kW system, 200 units) | ₹1,200 to ₹2,000 per month, depending on state tariff |
| Annual Bill Saving | ₹14,400 to ₹24,000 per year |
| Annual Net Metering Income (surplus export) | ₹3,000 to ₹8,000 per year, depending on usage and export |
| Total Annual Financial Benefit | ₹17,000 to ₹32,000 per year |
| System Lifespan | 25 years with minimal maintenance |
| Payback Period on Net Household Cost | 4 to 7 years, depending on system size and state tariff |
| Lifetime Financial Benefit (25 years) | ₹4 lakh to ₹8 lakh per household |
| Carbon Offset (lifetime) | Approximately 50 to 75 tonnes of CO₂ equivalent |
A household that invests its subsidised share of ₹60,000 to ₹1,00,000 in a PM Surya Ghar installation and uses the system for its full 25-year lifespan generates a lifetime financial return of ₹4 lakh to ₹8 lakh — among the highest return-on-investment available from any government-linked household financial decision. The combination of bill elimination, net metering income, and rising electricity tariff protection makes rooftop solar not merely an environmental choice but a compelling household financial strategy for every eligible Indian homeowner.
