Solar Panel Installation in Delhi — Area-Wise DISCOMs, Permissions, Cost and Timeline
Solar panel installation in Delhi follows the same national process as everywhere in India, but the details depend on your area, your electricity provider and your type of building. A home in Rohini deals with Tata Power DDL, a home in Dwarka with BSES Rajdhani, and a home in Mayur Vihar with BSES Yamuna. Each has its own portal habits and inspection style.
This guide walks through the full process for Delhi, from the first site visit to the net meter. It also covers area-wise DISCOMs, the permissions you need, typical costs, and a realistic timeline.
Who Provides Electricity in Your Part of Delhi?
Delhi has three distribution companies (DISCOMs). Your solar application goes to the one that supplies your connection, so check the name on your electricity bill first.
| DISCOM | General area | Example localities |
|---|---|---|
| Tata Power DDL | North and North-West Delhi | Rohini, Pitampura, Model Town, Shalimar Bagh, Narela |
| BSES Rajdhani (BRPL) | South and West Delhi | Dwarka, Janakpuri, Vasant Kunj, Saket, Najafgarh |
| BSES Yamuna (BYPL) | Central and East Delhi | Mayur Vihar, Laxmi Nagar, Preet Vihar, Shahdara, Vivek Vihar |
Boundaries overlap in some colonies, so always confirm with your bill. Solar Squad’s office is in Begum Vihar, Delhi 110086, so we work regularly in North and North-West Delhi and across the rest of the city.
Step-by-Step Solar Panel Installation in Delhi
- Site survey and sizing: the installer measures shadow-free roof area, checks structure and studies your last 12 bills. Allow about 100 sq ft per kW. Our guide on how many solar panels a 3BHK home needs helps you size.
- Portal registration: register on the PM Surya Ghar portal using your DISCOM and consumer number.
- Feasibility approval: the DISCOM checks your sanctioned load and the loading on your local transformer. Do not order equipment before you receive this.
- Quotation and agreement: sign a component-wise quote that names the panel model, inverter brand, structure and warranty.
- Material delivery and civil work: structure foundations or base plates are fixed on the terrace.
- Panel, inverter and wiring installation: usually completed in a few days for a home system.
- Testing and documentation: the installer tests the system and uploads photographs and reports.
- Net meter application and DISCOM inspection: an engineer checks earthing, protection, inverter specifications and isolation arrangements.
- Net meter installation and commissioning certificate: the system goes live.
- Subsidy claim: the central subsidy comes by DBT, while the Delhi subsidy and GBI flow through your electricity account.
For the detailed meter process, see our guide to net metering in Delhi.
How Long Does Solar Panel Installation in Delhi Take?
The physical installation of a home system takes only a few days. The paperwork takes longer. A straightforward residential application usually takes about four to seven weeks from feasibility approval to commissioning, as long as your documents are clean and the installation passes inspection the first time.
- Week 1: survey, registration and quotation.
- Weeks 1–3: DISCOM feasibility approval.
- Weeks 3–4: material delivery and installation.
- Weeks 4–7: inspection, net meter and commissioning.
Subsidy credit often arrives several weeks after commissioning. See our solar subsidy in Delhi guide for the timeline and common delays.
Permissions and Documents for Solar Panel Installation in Delhi
- Latest electricity bill with consumer number, sanctioned load and connection type.
- Aadhaar and PAN of the connection holder.
- Proof of ownership, or an NOC from the owner.
- Cancelled cheque in the same name as the electricity connection.
- NOC from the RWA or other floor owners if the roof is shared.
- Roof photographs and layout, prepared by the installer.

Solar Panel Installation in Delhi for Different Home Types
Independent house with a flat RCC terrace
This is the easiest case. The structure can be fixed on the slab with proper waterproofing, and shadow-free space is usually plentiful.
Builder floor or top-floor flat
Roof rights and consent from other owners matter. Agree on the cable route and structure placement in writing. For shared roofs and societies, read our guide to solar for apartments in Delhi.
Homes with water tanks, barsati and parapets
Shadows from tanks, parapets and neighbouring buildings can cut output. An elevated structure can recover usable space but costs more.
Sheet roofs on shops and workshops
These need a structural check and different clamps. Heavy sheet corrosion or old asbestos roofing needs strengthening before installation.
What Does Solar Panel Installation in Delhi Cost?
In 2026, on-grid home systems cost roughly ₹60,000 to ₹75,000 per kW before subsidy. A 3kW system is about ₹1.85 lakh to ₹2.20 lakh, and a 5kW system is about ₹3.10 lakh to ₹3.60 lakh. After the central and Delhi subsidy of ₹1,08,000 at 3kW and above, many households pay well below those figures. See our detailed solar panel price in Delhi guide for a full breakdown.
Checklist for the Day of Solar Panel Installation in Delhi
- The panel model number on the carton matches the model in your quotation and the ALMM list.
- The inverter brand and model match the quote.
- The structure is hot-dip galvanised or equivalent, with no loose bolts.
- DC and AC cables are properly labelled, clipped and protected from the sun.
- Earthing pits and lightning protection are installed, not just promised.
- Roof penetrations are sealed against monsoon leaks.
- You receive photographs, serial numbers and warranty cards before final payment.
Best Time for Solar Panel Installation in Delhi
You can install any time of year. Many people wait for summer, but the approval process takes weeks anyway, so starting early helps you generate sooner. October to March is also a comfortable time for roof work, with milder weather than the peak summer and heavy monsoon months.
After Installation: Keep Your System Healthy
Dust and smog in Delhi can reduce output by 10–18% if panels are not cleaned. Plan regular cleaning and a yearly inspection. Our guide to solar panel maintenance in Delhi NCR and our solar AMC in Delhi explainer cover this in detail.
Conclusion
Solar panel installation in Delhi is straightforward when you follow the process in order: survey, registration, feasibility approval, installation, inspection and net metering. Identify your DISCOM first, check your sanctioned load, confirm roof rights, and insist on a component-wise quote. Most homes are live within four to seven weeks.
