If you live in Delhi and are looking at rooftop solar, the number you have probably seen quoted is Rs 78,000. That is only the central subsidy. Delhi adds its own state subsidy on top, which for a 3 kW system takes the total to roughly Rs 1.08 lakh.
On a system costing around Rs 2 lakh, that is more than half the cost covered. It changes the arithmetic substantially, and a surprising number of Delhi homeowners plan their budget without knowing it exists.
How the two stack. The central PM Surya Ghar subsidy pays Rs 30,000 per kW for the first 2 kW, plus Rs 18,000 for the third kilowatt, capping at Rs 78,000 for any system of 3 kW or above. The Delhi state subsidy adds approximately Rs 30,000 for 3 kW systems. Both are aimed at the same residential rooftop installations, and you apply through the same route.
There is also mention in some sources of a generation-based incentive in Delhi, paid per unit generated for smaller systems, which over several years can add a further meaningful amount. Incentive structures of this kind are periodically revised, so confirm the current position with your DISCOM rather than relying on any figure quoted online, including this one.
What this does to your payback. A 3 kW system in Delhi costing Rs 2 lakh, less Rs 1.08 lakh in combined subsidy, leaves roughly Rs 92,000 net. Against monthly savings of around Rs 2,800 to Rs 3,200, payback lands closer to two and a half to three years rather than the three to five typical elsewhere. For a twenty-five year asset, that is an unusually good return.
The conditions still apply. The state top-up does not relax any of the central requirements. Your installer must be registered on the PM Surya Ghar national portal, your panels must be DCR-compliant, you need feasibility approval before installing, the system must be grid-connected with net metering, and it is one subsidy per connection. Fail any of those and you lose both the central and the state amount.
How to make sure you actually get it. Raise the state subsidy explicitly with your installer at quotation stage and ask how they handle the application for it. Some quotes are prepared assuming only the central amount, which understates your position. Confirm with your DISCOM what the current Delhi state subsidy is and what documentation it requires, because this is the piece most likely to be handled sloppily.
Where the money lands. As with the central subsidy, payment is by direct benefit transfer to your Aadhaar-linked bank account, following DISCOM inspection and commissioning. Expect roughly thirty to forty-five days after commissioning for the central portion.
One honest caution. State subsidy schemes are more changeable than the central one. Budgets get revised, caps get adjusted, and schemes occasionally pause. Everything here reflects the position in mid-2026. Verify before you commit money, and be wary of any installer whose quotation depends heavily on a state incentive they cannot document.
