Key takeaways
Delhi solar scheme is the city’s plan to help homes and buildings install rooftop solar panels. The programme cuts power bills by letting owners make electricity on their roofs. It also supports net metering, which credits extra power sent to the grid. The main steps are choosing a vendor, applying to the DISCOM, and getting approval.
- Who can apply: Homeowners, tenants with roof permission, housing groups, and many commercial or public buildings.
- What you need: A Delhi electricity connection, a suitable roof, and approval from your power distributor.
- How much support: Central aid can reach ₹78,000 for a 3-kilowatt home system.
- How long it takes: Metering often takes several weeks, depending on documents, inspection, and the local DISCOM.
What is the Delhi solar scheme?
The Delhi solar scheme builds on the Delhi Solar Energy Policy 2023, notified in 2024. The policy aims to add 750 megawatts of rooftop solar capacity by 2027. Rooftop solar means panels placed on a building rather than in a large solar farm.
Delhi wants more people to produce power close to where they use it. That can reduce demand on the grid during sunny hours. It can also help families lower monthly bills, but the savings depend on system size, sunlight, and daily power use.
The policy covers more than private houses. Apartment groups, institutions, commercial sites, and government buildings may also install systems if they meet local rules. In simple terms, the building needs a legal electricity connection and a roof that the applicant can use.
Who can buy solar panels in Delhi?
Most Delhi electricity consumers can buy a rooftop system through an approved installer. Homeowners can apply directly. Tenants may apply too, but they usually need written permission from the owner or housing group.
Residents should first check their electricity bill and identify the DISCOM serving their address. Delhi has three major private distributors: BSES Rajdhani, BSES Yamuna, and Tata Power Delhi Distribution. The application route and document list can vary slightly between them.
Applicants normally need an electricity account number, identity proof, address details, and roof-use permission. The installer should also check whether the roof gets enough sunlight. Shade from taller buildings, trees, or water tanks can reduce output.
Buyers should compare at least two quotes before signing. Ask about panel quality, inverter warranty, installation work, maintenance, and the final price after support. The cheapest quote may not offer the best long-term value.
How does the Delhi solar scheme subsidy work?
The biggest help for many households comes from the central PM Surya Ghar scheme. It offers ₹30,000 per kilowatt for the first 2 kilowatts and ₹18,000 for the next kilowatt. That makes the maximum support ₹78,000 for a 3-kilowatt system.
A kilowatt is a measure of a system’s power size. A 3-kilowatt system can suit a family with moderate electricity use, but every roof and bill is different.
The subsidy usually goes through the official application system after installation and checks. Buyers should use an approved vendor and keep invoices, bank details, and approval records. The national rooftop solar portal lists the official process and scheme details.
Delhi’s own policy also aims to make rooftop solar more attractive. Some benefits may depend on the consumer type and the policy rules in force. Applicants should confirm the latest amount with their DISCOM before paying a vendor.
How does net metering work?
Net metering is a billing system that counts both the electricity you take from the grid and the extra power your panels send back. A special meter records the two flows. So you pay for the net amount, rather than every unit drawn during the month.
For example, a home may use 300 units from the grid in one month. If its panels export 120 units, the bill may charge for the difference, subject to the current rules and tariff.
After installation, the DISCOM checks the system and replaces or upgrades the meter. The full process can take about 30 days in a smooth case, while delays may happen if documents are missing or an inspection finds a problem.
Consumers should not assume that every exported unit equals one full unit of bill savings. Tariffs, fixed charges, taxes, and settlement rules can affect the final bill. The Delhi government website is the best place to check policy notices and official updates.

How much can a Delhi home save?
The answer depends on the system and the home’s bill. A 1-kilowatt system may produce roughly 4 to 5 units a day in strong sunlight, though clouds, dust, and shade can lower that figure.
That means a 3-kilowatt system could produce around 360 to 450 units in a 30-day month under good conditions. Actual output changes across seasons. Solar panels also produce power in the daytime, so families using more power at night may still draw electricity from the grid.
| System size | Maximum central support | Simple use case |
|---|---|---|
| 1 kW | ₹30,000 | Small home or low use |
| 2 kW | ₹60,000 | Typical small family |
| 3 kW | ₹78,000 | Higher home use |
These figures show possible support, not guaranteed savings. A household should ask for an estimate based on its last 12 electricity bills. It should also check the roof’s age, because repairs after installation can add cost.
What should applicants do first?
Start with the electricity bill and roof check. Then select an approved vendor, submit the online application, and wait for the DISCOM’s approval before major work begins.
- Check roof space, shade, and ownership permission.
- Review the last 12 months of electricity use.
- Compare vendor quotes and warranties.
- Apply through the official portal linked to your DISCOM.
- Keep inspection and meter records after installation.
The clearest takeaway is simple: the Delhi solar scheme can lower power costs, but the benefit depends on a safe installation and correct meter approval. Keep every document, and ask the DISCOM about delays instead of relying only on a vendor.

What the verified record says
The latest Delhi solar scheme announcement concerns a proposed revision offering free 3 kW rooftop systems to eligible households consuming up to 400 units a month. The chief minister said the target was about 2.3 lakh consumers by March 2027, according to The Economic Times. It builds on the Delhi Solar Energy Policy 2023, notified in 2024. The official portal and gazetted policy remain the primary references for published rules.
What the headline does not prove
Cabinet approval and a public target do not automatically make every installation route operational. Eligibility documents, vendor empanelment, roof rights, technical feasibility, subsidy flow, metering and grievance rules must be published and implemented. Applicants should not pay an unverified seller who guarantees a free system. They should confirm the application on the official portal or with their distribution company. The final order must explain how Delhi and central support interact and who owns the equipment.
This distinction prevents a common error: treating an agenda, target, claim or early trend as a completed result. Dates and attribution matter. Where a company or public office supplies a number, that source is named. Independent coverage confirms the event but does not turn every assertion into an established fact.
Why this development matters
A no-upfront-cost 3 kW system could widen access for households unable to finance equipment even when lifetime savings look attractive. It could also create a large pipeline for approved vendors and distribution companies. The challenge is neighbourhood-scale execution: roofs need structural and shade checks, meters need approval, panels need safe wiring and consumers need service after installation. A 2.3 lakh-home target is also a workforce, procurement and quality-control programme.
Decision-makers should separate facts that change an action today from signals that deserve monitoring. Consumers should verify eligibility. Businesses should preserve records and model outcomes. Investors should read filings rather than infer completed transactions from agendas. A disciplined reading lowers the risk of acting on a claim that later changes.
What to watch next
Verify the consumer-number window, monthly-unit calculation, roof consent, warranty, maintenance responsibility and net-metering treatment. BSES explains net metering, while NDMC has a solar subsidy page. The final operational notice should override media shorthand. Keep approvals and invoices, and never share an OTP with a door-to-door seller. For context, see investment pipeline reporting.
