Delhi rooftop solar subsidy 2026: up to ₹26,000 per kW from the state

"Delhi mein ₹78,000 extra milega?" Up to that, yes, and "up to" is the part to stress. Delhi's state subsidy is not a fixed amount per kW. It is the lower of two figures, and one of them depends on a cost arrived at through bidding under the DISCOM Trusteeship Model. This post reads the Delhi Solar Portal's own page, sets out the most each size can get, and lists what the page leaves open.

The short answer

A Delhi household on PM Surya Ghar can get two subsidies:

• Central: ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000 (MNRE scheme guidelines, effective 13 February 2024, verified).
• State: up to ₹26,000 per kW for the first 3 kW, never more than ₹78,000 (Delhi Solar Portal, state subsidy page, read on 30 September 2026).

The state figures are ceilings, so the totals are too:

• 1 kW: ₹30,000 + up to ₹26,000 = up to ₹56,000
• 2 kW: ₹60,000 + up to ₹52,000 = up to ₹1,12,000
• 3 kW: ₹78,000 + up to ₹78,000 = up to ₹1,56,000
• 5 kW: still ₹78,000 + up to ₹78,000 = up to ₹1,56,000

The central figures are fixed. The state figures are the most the rule allows, not what a given job will get.

What the page says

The page opens: "GNCTD will provide a subsidy for all solar projects as given below". For residential consumers, its table gives the "Total Delhi Capital Subsidy maximum upto (₹/kW)":

• "≤ 2 kW": ₹26,000
• "> 2 kW but ≤ 3 kW": ₹26,000
• "> 3 kW up to 10 kW": "No additional subsidy"

Under the table sits the rule that decides the amount: "State Subsidy shall be equal to (the cost arrived at through bidding under the Discom Trusteeship Model minus the PM Surya Ghar subsidy) or ₹26,000 × Plant Capacity (in kW), whichever is lower, subject to a maximum limit of ₹78,000." A footnote adds: "Solar installations will also be undertaken under Discom trusteeship model through bidding."

The scheme overview the portal links, a one-page PDF created on 11 September 2026, explains where the number came from. The Second Amendment to the Delhi Solar Energy Policy raised the state subsidy to ₹78,000, and it is "in addition to the subsidy of up to ₹78,000/- being provided under the PM Surya Ghar Yojana".

Why ₹26,000 per kW is a ceiling

The rule takes the lower of two figures:

• ₹26,000 × the system's kW. This one you can work out.
• The trusteeship bid cost minus the central subsidy. This one you cannot. It is the cost arrived at through bidding under the DISCOM Trusteeship Model, and the page does not print it.

So the state part is never more than ₹26,000 per kW, never more than ₹78,000, and never more than the part of the bid cost that the central subsidy leaves unpaid. Whether a job gets the full ₹26,000 per kW depends on that bid cost.

Don't fill the gap with a cost of your own. MNRE's benchmark, your quote or a market price is not "the cost arrived at through bidding". A number worked out that way looks precise and has no source.

What the page does not say

Three things a quote needs are not on the page, so we mark each one not confirmed:

• Which cost applies outside the trusteeship route. The formula names only the trusteeship bid cost. For a system a private installer sells and installs on its own, which cost the state uses is not confirmed.
• Who applies. The page does not say whether the consumer, the vendor or the DISCOM applies for the state part. Not confirmed.
• When it is paid. The page gives no timeline. Not confirmed.

The page grants the subsidy "for all solar projects" and says trusteeship installations will "also" happen, so it does not read as trusteeship-only. But it does not say how a private job's amount is worked out. Until the portal does, check on solar.delhi.gov.in that the job qualifies before you quote the state part.

What the customer pays at MNRE's benchmark

MNRE's benchmark cost is ₹50,000 per kW up to 2 kW and ₹45,000 per kW above that. It is the reference the central subsidy is set against, not a market price, and the guidelines do not say whether it includes GST. We add GST on top at the blended 8.9% from the 70:30 goods and services split (Notification 9/2025-Integrated Tax (Rate), effective 22 September 2025, verified).

After the central subsidy alone:

• 1 kW: ₹50,000 + ₹4,450 GST = ₹54,450. Less ₹30,000: ₹24,450.
• 2 kW: ₹1,00,000 + ₹8,900 GST = ₹1,08,900. Less ₹60,000: ₹48,900.
• 3 kW: ₹1,45,000 + ₹12,905 GST = ₹1,57,905. Less ₹78,000: ₹79,905.

We stop there on purpose. Taking the Delhi part off these figures would mean using the benchmark as the bid cost, and the benchmark is not the cost the page names. Show the state part on its own line, below the net price, as "up to ₹26,000 per kW, subject to the Delhi Solar Portal".

The free-plant route

The same overview says consumers whose average use is below 400 units a month "can now avail the facility of having a solar plant installed completely free of cost by the Government of Delhi". It adds that the government "is going to empanel solar vendors" for plants up to 3 kW under "Utility-Led Aggregation (ULA)/ Discom Trusteeship Model", and that the selected vendor will visit "depending upon your consent".

Ask the units first. A home under 400 units a month may be better served by that route, or may wait for it. Say so plainly. A customer who hears about the free plant after paying you will remember that you didn't mention it.

The bill it saves

Delhi has three DISCOMs in our rates file: BSES Rajdhani, BSES Yamuna and Tata Power-DDL. We don't have a verified domestic tariff for any of them yet, so there is no bill-saving example in this post. Our subsidy calculator uses a general estimate for a DISCOM without a verified tariff and says so on screen. Don't quote that as the customer's tariff.

What goes wrong on Delhi quotes

• ₹26,000 per kW written as a fixed amount. It is a ceiling. The rule takes the lower of two figures.
• Your own price in the formula. The page names the trusteeship bid cost, not yours.
• More promised above 3 kW. The table says "No additional subsidy" above 3 kW, up to 10 kW. The state part stops at ₹78,000, and so does the central one.
• The old figure. The portal's FAQ still gives the 2023 policy's capital subsidy, ₹2,000 per kW up to ₹10,000 per consumer. The state subsidy page and the scheme overview carry the amended figures. A customer who quotes the FAQ back to you is reading the older text.
• A date promised. The page gives none.

Frequently asked questions

Is the Delhi subsidy in addition to PM Surya Ghar?

Yes. The scheme overview says the state's ₹78,000 is "in addition to" the central subsidy of up to ₹78,000.

How much does a 3 kW home get from Delhi?

Up to ₹78,000. The exact amount depends on the trusteeship bid cost, which the page does not print. For a job outside that route it is not confirmed.

Does a 5 kW system get more?

No. Above 3 kW the page says "No additional subsidy".

Who applies for the state part, and when is it paid?

Not confirmed. The portal's disbursal SOP, dated 11 October 2024, covers the 2023 policy's older subsidy, which the DISCOM passes on in the first electricity bill after commissioning. Whether that process carries over to the amended subsidy is not confirmed.

What about housing societies?

The page lists ₹11,000 per kWp for group housing societies and RWAs, for common facilities including EV charging, up to 500 kWp at 3 kWp per house. It calls the figure "proposed", and a footnote caps it at the difference between the plant cost and the PM Surya Ghar subsidy per kW, as discovered through bidding.

The subsidy calculator works out the central subsidy and GST for any size. For the Delhi part, go by the rule above: at most ₹26,000 per kW and ₹78,000, subject to the portal. The solar cost calculator turns a price into a net figure. Other states are in our state-by-state subsidy guide.
