Rooftop solar subsidy in Rajasthan and the 150 free units scheme

The central subsidy, the state’s ₹17,000 top-up for households on the free electricity scheme, what the two add up to, how the 150 free units work, the community-solar route for homes without a roof, and how to apply.

Last updated: 18 October 2026 · Luminity

Rajasthan has tied its rooftop solar push to free electricity. Households registered under the state’s Mukhyamantri Nishulk Bijli Yojana, which already gave them 100 free units a month, can get up to 150 free units a month by putting a 1.1 kW solar system on their roof. To pay for the plant, the state adds ₹17,000 to the central PM Surya Ghar: Muft Bijli Yojana subsidy and gives a smart meter free. The state calls it the “150 यूनिट प्रतिमाह निःशुल्क बिजली योजना” (150 units a month free electricity scheme); its consent portal opened on 13 October 2025.

As on 18 October 2026: central subsidy ₹30,000 per kW for the first 2 kW plus ₹18,000 for the third kW (maximum ₹78,000). Rajasthan adds ₹17,000 and a free smart meter for consumers registered under the Mukhyamantri Nishulk Bijli Yojana. Combined for a registered household: ₹50,000 for 1.1 kW, ₹77,000 for 2 kW, ₹95,000 for 3 kW and above. Figures can change; the amount on your national-portal application and your discom’s records is the one that counts.

What you get, by system size

Rajasthan is a general-category state for PM Surya Ghar, so it gets the standard central rates notified with effect from 13 February 2024. The state amount is a flat ₹17,000 for eligible consumers, according to the scheme’s FAQ and a district press note from the state’s information department (DIPR) in April 2026.

System size	Central (₹)	Rajasthan, registered households (₹)	Total subsidy (₹)
1.1 kW (the scheme size)	33,000	17,000	50,000
2 kW	60,000	17,000	77,000
3 kW	78,000	17,000	95,000
Above 3 kW	78,000	17,000	95,000

A household that is not registered under the free electricity scheme gets only the central column. The central amount stops growing at 3 kW, so a 5 kW system gets the same subsidy as a 3 kW one. Housing societies and residents’ welfare associations get central assistance of ₹18,000 per kW for common facilities within the scheme’s 500 kW cap; check with your discom whether any state amount applies to a society plant.

How the 150 free units work

Who: domestic consumers registered under the Mukhyamantri Nishulk Bijli Yojana. Check with your 12-digit K number on your discom’s scheme portal.
What you must do: install a rooftop solar plant (1.1 kW for the scheme) through a vendor registered on the PM Surya Ghar portal, on net metering.
What you get: up to 150 units a month free. If your use in a month goes above 150 units, the extra units are billed at the normal tariff. If solar generation is more than your consumption, the scheme FAQ says you get a zero bill.
Ownership: the plant belongs to the household, not the discom.
Roll-out: the FAQ says the scheme is being implemented in phases, in line with the 2025-26 budget announcement.

When the cabinet approved the design in 2025, ministers said about 1.04 crore registered domestic consumers stood to benefit. They described three routes. About 27 lakh families using more than 150 units a month would get 1.1 kW rooftop plants paid for by the ₹33,000 central and ₹17,000 state amounts. About 11 lakh families using less than 150 units a month, and with a usable roof, would get 1.1 kW plants installed free by the discoms through vendors the discoms select. Registered consumers with no roof would be covered by community solar plants built at the discoms’ cost, with 150 units a month credited through virtual net metering. Ministers also announced ₹1,100 for the first five lakh consumers in each category.

Net metering in Rajasthan

Grid-connected rooftop plants are governed by the RERC (Grid Interactive Distributed Renewable Energy Generating Systems) Regulations, 2021, amended in 2023, 2024 and 2025. The points that matter for a household:

Size: up to 100% of your sanctioned load or contract demand. Raise the sanctioned load first if you want a bigger plant.
Transformer limit: total distributed renewable capacity on a distribution transformer is capped at 50% of its rating, up from 30% before 2021, so approval can depend on what your neighbours have already installed.
Agreement: the net metering connection agreement runs for 25 years.
Meter: you may buy the meter yourself, for testing and installation by the discom. Households on the 150-unit scheme get a smart meter free from the state.
Surplus: the settlement period is the April-March financial year. Surplus exported by a domestic consumer that is unadjusted at year-end is bought by the discom at the weighted average tariff discovered through competitive bidding in the previous financial year, a utility-scale solar rate far below retail tariffs. For consumers other than domestic, leftover surplus lapses.
Charges: power from a self-owned net-metered system on your own premises is exempt from banking and wheeling charges and from cross-subsidy and additional surcharges.
Faster approvals: under the 2025 amendment, domestic systems up to 10 kW need no technical feasibility study, and connectivity is due within 30 days of technical clearance. The amendment also waives the application fee, security deposit and meter testing fee for PM Surya Ghar households until the target of five lakh homes is met.
Shared systems: the 2025 amendment allows virtual net metering, where several consumers share one plant, and group net metering, where one consumer offsets several connections. Plants can sit on a roof, a balcony, the ground, above water or on another raised structure, which opens solar to tenants and flat owners.

Because year-end surplus earns only the bid-discovered utility-scale rate, a plant sized to your own annual use usually pays back better than an oversized one that exports a lot.

How many homes have signed up

A state energy department official told Business Standard in January 2026 that more than 13,000 rooftop plants a month were being installed in Rajasthan, that over 2,77,000 consumers had registered for the 150-unit scheme in less than three months, and that the Jaipur, Jodhpur and Ajmer discoms had transferred the ₹17,000 state subsidy to more than 2,000 consumers. The April 2026 DIPR note said more than 1.32 lakh families had taken collateral-free loans for up to 90% of the cost of a solar plant, and that Rajasthan was among the top five states for the scheme.

How to apply

Check that you are registered under the Mukhyamantri Nishulk Bijli Yojana and that your sanctioned load is at least as large as the plant you want.
Register your consent on your discom’s 150-unit scheme portal, 150unitmuftbijli.bijlimitra.com, using your K number and an OTP, or submit the consent form at your nearest sub-division office.
Apply on pmsuryaghar.gov.in with your discom and consumer number. Our PM Surya Ghar guide covers the documents and steps.
Choose a vendor registered on the national portal. Agree the design, full price and what is included (structure, wiring, net meter, maintenance) in writing.
After installation the discom inspects the plant and installs the net meter. The central subsidy is released through the national portal; the state ₹17,000 is transferred by the discom.

Complaints and questions about the scheme go to your discom’s sub-division, division or circle office on working days, according to the scheme FAQ.

Common pitfalls

Assuming you are registered. The ₹17,000 and the 150 free units are only for consumers registered under the free electricity scheme. Check your K number first.
Counting the state amount per kilowatt. It is a flat ₹17,000, not a per-kW rate.
Using more than 150 units. The free units stop at 150 a month; the rest is billed at the normal tariff.
Oversizing for export. Year-end surplus earns a low utility-scale rate.
A full transformer. If the 50% limit on your transformer is used up, approval can wait. Ask early.
Unregistered vendors and agents. Use a vendor registered on the national portal, and do not pay a middleman for “registration”. The PM Surya Ghar guidelines describe no fee for the national-portal application, and RERC’s 2025 amendment waives the application fee for PM Surya Ghar households.

Questions people ask

How much subsidy does a Rajasthan household get for rooftop solar?

Every eligible household can claim the central PM Surya Ghar subsidy: ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, up to ₹78,000. Households registered under the Mukhyamantri Nishulk Bijli Yojana (the chief minister’s free electricity scheme) also get ₹17,000 from the state and a free smart meter. For a registered household that is ₹50,000 for a 1.1 kW system, ₹77,000 for 2 kW and ₹95,000 for 3 kW or more.

What is the 150 units free electricity scheme?

It links the state’s free electricity scheme with PM Surya Ghar. Consumers registered under the Mukhyamantri Nishulk Bijli Yojana, who earlier got 100 free units a month, get up to 150 units a month free once a rooftop solar system (1.1 kW for the scheme) is installed. Units used above 150 in a month are billed at the normal tariff.

Who is eligible for the ₹17,000 state subsidy?

Domestic consumers registered under the Mukhyamantri Nishulk Bijli Yojana. You can check eligibility with your 12-digit K number on your discom’s 150-unit scheme portal. A household that is not registered can still claim the central subsidy, but not the state ₹17,000.

Is the 1.1 kW system really free?

For a registered household the state’s arithmetic is ₹33,000 central plus ₹17,000 state, or ₹50,000, which the government says covers a 1.1 kW plant. Whether you pay anything depends on your vendor’s quote and on which route you take: for low-use homes (under 150 units a month) with a usable roof, the discoms install 1.1 kW plants through their own selected vendors. Get the full price in writing before you sign.

What if I do not have a roof of my own?

For registered consumers using less than 150 units a month who have no roof, the state cabinet decided that the discoms would set up community solar plants, at the discoms’ cost, and credit 150 units a month to each consumer’s account through virtual net metering. The regulator RERC approved the community-solar model in October 2025. Separately, RERC’s 2025 amendment allows virtual and group net metering, which lets tenants and flat owners share a plant on a terrace, ground or other structure.

How do I apply?

First register your consent on your discom’s 150-unit scheme portal (150unitmuftbijli.bijlimitra.com) or at your nearest sub-division office. Then apply on the PM Surya Ghar national portal, choose a vendor registered on that portal, and get the plant installed and net-metered. The central subsidy comes through the national portal; the state amount is released by the discoms.

Who owns the solar plant?

The household does. The scheme FAQ says the installed plant is fully owned by the consumer.

What happens to surplus units?

Rooftop plants are on net metering. Under RERC’s 2021 rules, surplus exported by a domestic consumer that is still unadjusted at the end of the April-March financial year is bought by the discom at the weighted average tariff discovered in the previous year’s competitive solar bidding, which is far below the retail tariff. Size the plant to your own use rather than for export.
