Where the money goes in a typical ₹3,50,000 on-grid 7kW rooftop system (before subsidy):
| Component | What you get | Approx. cost |
|---|---|---|
| Solar panels | 13 × 550W Mono PERC / TOPCon (DCR for subsidy) | ₹1,68,000 – ₹2,24,000 |
| On-grid inverter | 7kW string inverter | ₹22,000 – ₹38,000 |
| Mounting structure | GI / aluminium rooftop frame | ₹35,000 – ₹52,500 |
| Cables, earthing, protection | DC/AC cables, ACDB/DCDB, lightning arrestor | ₹17,500 – ₹26,250 |
| Installation & net meter | Labour, DISCOM paperwork, net meter | ₹17,500 – ₹35,000 |
| Type | Price before subsidy | Works in power cut? |
|---|---|---|
| 7kW on-grid | about ₹3,50,000 | No |
| 7kW hybrid + 10 kWh lithium battery | ₹4,60,000 – ₹5,30,000 | Yes |
The ₹78,000 PM Surya Ghar subsidy applies to both when a registered vendor installs DCR panels with net metering. Panel brand also changes the price: Waaree, Adani and Tata panels cost roughly ₹25–₹38 per watt, so 7kW of panels costs about ₹1,75,000 – ₹2,66,000. Installers quote complete systems, so compare at least three quotes. See the solar panel price list, solar inverter price list, or the free solar calculator.
Most states and UTs get the same ₹78,000 central subsidy (PM Surya Ghar) for a 7kW system. Hill, North-East and island states (e.g. Assam, Himachal Pradesh, Uttarakhand, Jammu and Kashmir, Sikkim) get 10% more — ₹85,800 — as shown in the table below. The only state top-up is in Uttar Pradesh, where an extra state-level subsidy (₹15,000/kW, up to ₹30,000) reduces the net cost further.
