Rooftop solar price in Delhi, 1 to 10 kW

For many Delhi homes, 3 kW is the sensible starting point. It generates about about 326 units a month a month on the planning assumptions used here.

The published price is ₹1,99,000 to ₹2,10,000. After the central and Delhi subsidy, the estimated amount is ₹43,000 to ₹54,000. Delhi also pays ₹3 per unit on the electricity your system generates, worth about ₹11,745 a year for five years at this output.

Use the table below to compare other system sizes, then choose the electricity-board guidance that matches the name on your bill.

The price table for Delhi

The published price covers panels, inverter, mounting structure, net metering, installation and warranty. The central subsidy is ₹30,000 per kW for the first 2 kW plus ₹18,000 for the third, capped at ₹78,000 for 3 kW and above. Delhi adds ₹26,000 per kW, capped at ₹78,000 (3 kW). The two are paid on top of each other. The earlier ₹2,000 per kW, maximum ₹10,000 (replaced in July 2025) figure is no longer current.

A 10 kW system is priced per site because structure, cable run and inverter choice vary far more between roofs. The subsidy on it is the same ₹78,000 plus ₹78,000 (3 kW), and the GBI steps down to ₹2 per unit.

The incentive Delhi pays that Uttar Pradesh does not

Delhi pays for generation as well as for installation. The GBI is ₹3 per unit for home systems up to 3 kW and ₹2 per unit for systems above 3 kW up to 10 kW, for 5 years from commissioning, paid monthly against the bill; any excess to the bank account. On the planning yield used across this site, a 3 kW system earns ₹11,745 a year, or ₹58,725 over the five years. A 5 kW system earns ₹13,050 a year, because the rate steps down but the units go up.

The incentive is claimed separately from the central subsidy: subsidised systems: apply on the PM Surya Ghar portal and claim the Delhi subsidy and GBI on solar.delhi.gov.in; unsubsidised systems: the DISCOM portal. Verde Solaire files both applications. The higher rate applies to any home system of 3 kW or less; larger home systems use the lower rate.

Why 3 kW, and when 5 kW makes sense

The subsidy formula is 60% of the benchmark cost for the first 2 kW and 40% for the part between 2 and 3 kW, capped at 3 kW. The combined ₹1,56,000 therefore covers roughly half of the published 3 kW price, and nothing more is added above 3 kW. At 5 kW the same subsidy sits against a higher price, so the net cost per kW rises; the extra 2 kW still generates at the same rate, and a home using more than about 400 units a month usually needs it. The official sizing guide is 0–150 units a month: 1–2 kW · 150–300 units: 2–3 kW · above 300 units: above 3 kW. Average twelve months of bills, not the June one.

The Delhi 3 kW page and the Delhi 5 kW page work each size through in full; the sizing guide covers the roof-area and sanctioned-load checks.

Which electricity board you are on, and what it requires

Delhi has three distribution licensees and one municipal area. BSES Rajdhani serves south and west Delhi, BSES Yamuna serves east and central Delhi, and Tata Power-DDL serves north and north-west Delhi; the NDMC area is served by the New Delhi Municipal Council and is handled separately. The name at the top of your bill decides the portal. BSES Rajdhani uses rts.bsesdelhi.com (helpline 19123, extension 3), Tata Power-DDL has the net-metering application and manual on tatapower-ddl.com, and for subsidised systems in every area PM Surya Ghar applicants apply through the national portal; everyone else through the DISCOM or state portal.

Under the DERC net-metering guidelines amended on 16 July 2026, a domestic connection up to 10 kW is to be connected within 10 days and there is no application fee; above 10 kW the timeline is 25 days. Since the 2024 amendment, no feasibility study is needed up to 10 kW on the same supply type, and the DISCOM handles any load increase or transformer upgrade. Surplus generation is not lost: credits roll over month to month, and any surplus left at the end of the financial year is paid at the DISCOM's average power purchase cost.

Those are the rules; practice has been slower. Arun Sibal, whose New Delhi house was fitted within days of payment, wrote that the only issue was "the time taken in installing the net meter from BSES, which was actually not in control of Verde", and that the team kept him informed throughout. Verde Solaire is a registered PM Surya Ghar vendor in both Delhi and Uttar Pradesh and is registered with IOCL, UHBVN, DHBVN, CEL, IPGCL, BRPL and CREST for solar power plant installations. The process for each board is on the Delhi net-metering page, with guides for BSES Rajdhani, BSES Yamuna and Tata Power-DDL.

What a Delhi electricity bill does after solar

DERC's last published domestic tariff schedule, for FY 2021-22, charges ₹3.00 (0–200 units), ₹4.50 (201–400), ₹6.50 (401–800), ₹7.00 (801–1,200) and ₹8.00 (above 1,200) per unit, plus a fixed charge of ₹20 (up to 2 kW), ₹50 (2–5 kW), ₹100 (5–15 kW), ₹200 (15–25 kW) and ₹250 (above 25 kW) per kW per month, a regulatory surcharge of 8% and a fuel surcharge that changes monthly and stood at 17.94% for BSES Rajdhani in June 2026.

A home on 400 units a month sits at the top of the second slab. A 3 kW system generating about 326 units a month removes most of that consumption, and the two surcharges, which the calculator applies to the energy and fixed charges together, fall with it. The fixed charge stays, which is why the bill does not become zero. On the calculator's default assumptions the net cost of a 3 kW system in Delhi is recovered in under two years once the GBI is counted. The bill calculator does the arithmetic for your own units and sanctioned load, and the Delhi tariff explainer walks through each line of the bill.

Delhi's free-power subsidy is separate. It is 0–200 units a month free; 201–400 units at 50% off, capped at ₹800 a month; you must opt in, and with solar it is worked out on net units, that is import minus export. A home that imports fewer than 200 net units pays a near-zero energy charge either way, so the saving from solar is smaller for a subsidised household than the tariff alone suggests. The calculator does not model the free-power subsidy; treat its savings figure as an upper bound if you receive it.

The zero-upfront scheme: approved, not yet notified

On 1 September 2026 the Delhi Cabinet approved a second amendment offering up to 3 kW at zero upfront cost, "subject to technical feasibility" to households that averaged 400 units a month or less in FY 2025-26. The notification and operating rules are not yet published. If you use more than 400 units a month, or want more than 3 kW, the scheme as announced does not cover you and the paid route on this page is the one that applies. The zero-upfront explainer tracks what is approved, what is notified and the questions still open.

Paying for it: cash, loan or EMI

The PM Surya Ghar concessional loan is collateral-free, from nationalised banks, priced at repo rate plus 0.5 percentage points, which was 5.75% on 28 July 2026, over 10 years. Answers that quote around 7% (February 2024 figure, superseded) are repeating an old number. On the mid-point of the 3 kW net price the EMI comes out below the monthly saving on the calculator's defaults.

Verde Solaire has tie-ups with SIDBI, SBI and other NBFCs for collateral-free solar loans and prepares the paperwork with you. In July 2025 it published a Delhi offer under which the customer paid ₹10,000 upfront and financed the balance by EMI; the loan rate has changed since, so ask for the current terms in writing before you rely on them. The EMI calculator takes any principal, rate and tenure, and the solar loan page lists the lenders and documents.

Equipment and compliance

A subsidised system must use both the modules and the cells must be made in India, and from 1 June 2026 the cells must appear on the ALMM List-II as well as the modules. GST on a rooftop solar plant is about 8.9%: 5% on the panels and inverter (70% of the contract value) and 18% on the rest of the material and installation (30%).

Verde Solaire's published Delhi installations include a 10 kW system in Greater Kailash on Adani bifacial modules, where the customer wrote that the company fitted a better bifacial panel than the one agreed "without charging anything extra from us", and a 10 kW system in Janakpuri on Vikram modules with KSolare inverters. The company publishes 25-year performance warranties on all three panel types. Every quote names the make, model and wattage of each component so that you can check them against the approved lists; panels, inverters and batteries explains what the names mean, and the Greater Kailash and Janakpuri project pages show the two systems.

Where in Delhi we install

Verde Solaire's registered office is in Sarvodaya Enclave, New Delhi, and its July 2025 price post lists the areas it serves as Saket, CR Park, Greater Kailash and Defence Colony in the south; Preet Vihar, Laxmi Nagar and Mayur Vihar in the east; Janakpuri, Dwarka and Rajouri Garden in the west; Model Town, Rohini and Ashok Vihar in the north; and Karol Bagh, Patel Nagar and Daryaganj in central Delhi, along with NDMC colonies. Independent houses and builder floors both work; on a builder floor the roof right and the sanctioned load on your connection decide the size, which the builder floors guide explains. The Delhi installation page covers the survey, the shadow analysis and the structure; the company offers a free site evaluation and no-obligation proposal.

Customers in Delhi have described the work in their own words. S. C. Garg's Greater Kailash system, installed when the company still traded as Sirius Electric, has "been working continuously without a single day breakdown since 2017". K. K. Sharma in Chhatarpur was "highly impressed with their shadow analysis process". The reviews below are reproduced as written.
