Every solar EPC in India has had this conversation dozens of times. A homeowner asks: “How much subsidy will I actually get?” And the answer you give determines whether they sign up or disappear. Too vague, and they go to a competitor. Too complex, and they get confused. Too optimistic, and they feel cheated when the real amount shows up in their bank account.
This guide demystifies the current MNRE (Ministry of New and Renewable Energy) subsidy structure for 2026 under PM Surya Ghar, walks through worked examples for every popular system size, and shows you how to present the subsidy transparently in a quote that closes deals.
The Current Subsidy Structure
As of April 2026, the Central Financial Assistance (CFA) under PM Surya Ghar Muft Bijli Yojana for residential rooftop solar is structured in three slabs:
- First 1 kW: Rs 30,000
- Second and third kW (up to 3 kW): Rs 30,000 per kW (so the full 3 kW gets Rs 90,000)
- From 3 kW up to 10 kW: Rs 18,000 per additional kW (capped at 10 kW)
- Beyond 10 kW: No additional subsidy
So the maximum subsidy possible for a residential consumer is Rs 90,000 + (7 kW × Rs 18,000) = Rs 90,000 + Rs 1,26,000 = Rs 2,16,000 for a 10 kW system.
Worked Examples by System Size
2 kW System
A 2 kW system is suitable for a family with monthly electricity consumption of around 200–300 units (bill ~Rs 1,500–2,500/month).
- Gross installation cost (market rate, turnkey): ~Rs 1,20,000
- MNRE Subsidy: 2 kW × Rs 30,000 = Rs 60,000
- Net customer payment: Rs 60,000
- Typical payback period: 3–4 years on savings alone
3 kW System
The 3 kW sweet spot for most middle-income Indian households with bills around Rs 2,500–4,000/month.
- Gross installation cost: ~Rs 1,80,000
- MNRE Subsidy: 3 kW × Rs 30,000 = Rs 90,000
- Net customer payment: Rs 90,000
- Typical payback period: 3–4 years
5 kW System
Typical for upper-middle-income families with ACs, pool pumps, or larger homes. Bills around Rs 4,000–7,000/month.
- Gross installation cost: ~Rs 3,00,000
- MNRE Subsidy: Rs 90,000 + (2 kW × Rs 18,000) = Rs 90,000 + Rs 36,000 = Rs 1,26,000
- Net customer payment: Rs 1,74,000
- Typical payback period: 4–5 years
7 kW System
For large homes or small home-based businesses. Bills around Rs 7,000–10,000/month.
- Gross installation cost: ~Rs 4,10,000
- MNRE Subsidy: Rs 90,000 + (4 kW × Rs 18,000) = Rs 90,000 + Rs 72,000 = Rs 1,62,000
- Net customer payment: Rs 2,48,000
- Typical payback period: 4–5 years
10 kW System
The maximum subsidised capacity. Villas, large independent houses, or small commercial mixed-use.
- Gross installation cost: ~Rs 5,80,000
- MNRE Subsidy: Rs 90,000 + (7 kW × Rs 18,000) = Rs 2,16,000 (maximum)
- Net customer payment: Rs 3,64,000
- Typical payback period: 4–6 years
Cost vs Subsidy vs Net Payment Table
| System Size | Gross Cost (Rs) | Subsidy (Rs) | Net Payment (Rs) | Annual Savings (Rs) | Payback |
|---|---|---|---|---|---|
| 1 kW | 65,000 | 30,000 | 35,000 | 10,800 | 3.2 yrs |
| 2 kW | 1,20,000 | 60,000 | 60,000 | 21,600 | 2.8 yrs |
| 3 kW | 1,80,000 | 90,000 | 90,000 | 32,400 | 2.8 yrs |
| 5 kW | 3,00,000 | 1,26,000 | 1,74,000 | 54,000 | 3.2 yrs |
| 7 kW | 4,10,000 | 1,62,000 | 2,48,000 | 75,600 | 3.3 yrs |
| 10 kW | 5,80,000 | 2,16,000 | 3,64,000 | 1,08,000 | 3.4 yrs |
Annual savings assume Rs 9 per unit blended residential tariff, 4.5 peak sun hours, 85% system efficiency, and 360 generation days.
ROI and Payback Period Calculation
The payback period is the single most effective selling tool. Most Indian homeowners understand payback period intuitively — “I get my money back in 3 years, then I have 22 years of free electricity.” Here is the honest formula:
Payback Period (Years) = Net Customer Payment / Annual Electricity Savings
For a 3 kW system with Rs 90,000 net cost and Rs 32,400 annual savings: 90,000 / 32,400 = 2.78 years. That is a compelling number. Over a 25-year panel lifetime, the homeowner saves approximately Rs 8 lakh in electricity — a 9x return on their Rs 90,000 investment.
Presenting the Subsidy in a Quote That Closes
The difference between a winning quote and a losing quote is rarely the price — it is the clarity of the savings story. Your quote should make the subsidy journey visually obvious.
A winning quote structure looks like this:
- Customer Details: Name, address, sanctioned load, monthly bill.
- Recommended System: Size in kW, number of panels, inverter brand, expected generation per month.
- Cost Breakdown: Modules, inverter, structure, BOS, installation, GST — itemised.
- Gross System Cost: The total before subsidy.
- MNRE Subsidy: Shown as a clear deduction line.
- Net Customer Payment: Bold, large font, unmistakable.
- Payment Milestones: Advance, post-survey, pre-installation, post-commissioning.
- Savings Projection: Monthly savings, annual savings, 25-year savings.
- Payback Period: Stated clearly in years.
- Warranty and Support: Product warranty, performance warranty, AMC options.
Common Customer Questions
- “When do I get the subsidy?” After installation, DISCOM inspection, and commissioning — typically 30–45 days after commissioning. It is credited directly to the customer’s bank account via DBT.
- “Do I pay the full amount first?” Yes. PM Surya Ghar is a reimbursement scheme. The customer pays the EPC the full amount, then receives the subsidy from the government. Some EPCs offer bridge financing to defer this.
- “Is the subsidy guaranteed?” Subject to successful DISCOM inspection and ALMM/BIS compliance, yes. If the installation fails inspection, subsidy may be denied — which is why working with a quality EPC matters.
- “Can I go beyond 10 kW?” Yes, but only the first 10 kW qualifies for subsidy. The excess capacity is at full cost.
- “Can a tenant claim the subsidy?” No — only the property owner with an electricity connection in their name can claim PM Surya Ghar subsidy.
How SolarNeo Auto-Calculates Subsidy
In SolarNeo, the moment you enter the system size in kW while creating a quote, the subsidy calculator kicks in automatically. It:
- Applies the current MNRE subsidy slabs without manual lookup.
- Shows gross cost, subsidy amount, and net payment as a visual breakdown.
- Computes annual savings based on your configured tariff and sun hours.
- Calculates payback period and 25-year savings.
- Generates a branded PDF quote with all numbers clearly laid out.
- Sends the quote to the customer via WhatsApp with a trackable link.
When MNRE revises the subsidy slabs, SolarNeo’s platform configuration is updated centrally — every company on the platform gets the new numbers automatically. No more manually updating Excel templates or training your sales team on new slabs.
The Bottom Line
The MNRE subsidy is the single biggest lever you have to close residential solar deals in India. Present it transparently, calculate it accurately, and build your quoting process around it. The EPCs who do this consistently see conversion rates 30–50% higher than those who treat the subsidy as an afterthought. Let SolarNeo handle the math so you can focus on the customer.
