Solar Installation for Apartments
Apartments can benefit from solar energy just as much as independent homes. With the right solar installation, apartment societies can reduce electricity bills for common areas, including lifts, corridor lights, water pumps and security systems. Whether you live in a high-rise building or manage a residential society, installing solar panels can help lower long-term electricity costs and make better use of available rooftop space.
- Why Apartment Societies Are Switching to Solar
Common-area power is one of the biggest line items in a society’s budget. And unlike a flat’s bill, it runs mostly during the day, right when solar produces the most.
Lower maintenance charges
Societies commonly cut common-area electricity costs by 60% to 80%. That saving goes straight back to residents.
Government subsidy of ₹18,000 per kW
Registered RWAs and group housing societies get central financial assistance for common-facility solar, up to 500 kW.
Fewer DG hours
With a hybrid setup, lifts and pumps keep running through short power cuts without firing up the diesel generator.
Higher property appeal
Buyers and tenants now ask about solar and EV charging. A solar-powered society simply looks better on a listing.
Zero effort for residents
Once it’s live, nobody has to do anything. It just runs for 25+ years.
Apartment Solar Power Installation: Society vs Individual Flat
Here’s how the two routes compare side by side.
| Society-Level Solar | Individual Flat Solar | |
|---|---|---|
| Who Applies | RWA / AOA | Flat owner |
| What It Powers | Lifts, pumps, lighting, STP, EV charging | That flat's own usage |
| Subsidy | ₹18,000 per kW | Up to ₹78,000 central + up to ₹30,000 UP state |
| Capacity Limit | 3 kW per flat, max 500 kW | Usually up to 3 kW |
| Approval Needed | AGM / committee resolution | RWA NOC + terrace allotment |
| Best For | Every society with open terrace space | Top-floor or penthouse owners |
For individual homeowners, our residential solar installation page covers the flat and villa route in detail.
Cost of Solar Installation for Apartments
Society systems are priced per kW, and larger systems cost less per kW. The subsidy requires DCR (Made-in-India) panels, which is what we use for every RWA project. Here’s a realistic picture with the ₹18,000/kW subsidy already deducted:
| Society Size | System Size | Approx. Cost | Subsidy | Net Cost | Approx. Monthly Savings |
|---|---|---|---|---|---|
| 50 to 100 flats | 20 kW | ₹11 to 12.5 lakh | ₹3.6 lakh | ₹7.4 to 8.9 lakh | ~₹17,000 |
| 100 to 200 flats | 50 kW | ₹26 to 30 lakh | ₹9 lakh | ₹17 to 21 lakh | ~₹42,000 |
| 200+ flats | 100 kW | ₹50 to 58 lakh | ₹18 lakh | ₹32 to 40 lakh | ~₹85,000 |
Indicative figures. Final cost depends on terrace layout, structure height and whether you add batteries.
Most societies recover their investment in 3 to 4 years. After that, the common-area power is close to free for another two decades. You can read more about subsidies and panel types on our solar blog.
For individual flats: a 3 kW system costs roughly ₹1.9 to 2.1 lakh. After central and UP state subsidy, many owners pay well under ₹1 lakh.
- How Solar Oorja Installs Solar in Apartments
Getting 200 residents to agree on anything is hard. We make the solar part easy.
Free terrace survey
We check shadow-free area, water tanks, parapet height and roof condition.
Load study
We go through 12 months of common-area bills to size the system correctly.
Proposal for your committee
You get a clear, one-page summary of cost, subsidy, savings and payback that’s easy to present at the AGM.
Paperwork and approvals
We help with the RWA resolution, the PM Surya Ghar application and DISCOM filings.
Installation
Our own crew installs using zero-drill, elevated mounting, so the terrace stays usable and water tanks stay accessible. Most society projects take 5 to 10 days.
Net metering and subsidy
We coordinate the meter installation and track the subsidy until it lands in the society’s account.
Monitoring and AMC
The committee tracks generation on a mobile app, and our 5-year AMC covers cleaning checks and maintenance.
On-Grid vs Hybrid Solar for Apartments
Most societies in our area do best with an on-grid solar system. It’s the cheapest option, qualifies fully for the subsidy and pays back fastest.
If your society deals with frequent outages, or you want lifts and pumps to keep running without the DG set, a hybrid solar setup adds battery backup for critical loads. We usually suggest backing up only essentials (one lift, water pumps, emergency lights) to keep cost in check.
Solar for Apartments Across Our Service Areas
Solar Installation for Apartments in Noida
From high-rise societies in Sectors 75, 76, 78 and 137 to the newer towers along the Noida Expressway and Sector 150, Noida has some of the best terraces in NCR for solar. Most connections fall under PVVNL, and we handle the full net metering process. Our office is in Sector 4, so a site visit is never far away.
Solar Installation for Apartments in Greater Noida
Greater Noida West (Noida Extension), Techzone 4, Gaur City and the Alpha and Beta sectors are packed with large societies that have big, open roofs. Most of Greater Noida is served by NPCL, and we know their approval process well. We also have a site office in Vaidpura for faster service.
Societies in Indirapuram, Vaishali, Raj Nagar Extension, Crossings Republik and Kaushambi often face higher common-area bills and more power cuts. That makes solar, especially hybrid, a strong fit. We manage PVVNL filings and design systems around your towers’ real load.

Frequently Asked Question
Can you install solar panels in an apartment?
Yes. The RWA can install a shared system for common areas, or an individual flat owner can install a small system on an allotted part of the terrace with the RWA’s NOC.
Can we install solar panels in apartments in India with a subsidy?
Yes. Under PM Surya Ghar, registered RWAs and group housing societies get ₹18,000 per kW for common facilities, up to 500 kW. Individual flat owners can separately claim up to ₹78,000 for their own system, plus up to ₹30,000 in UP state subsidy.
How much solar capacity can our society install under the subsidy?
The limit is 3 kW per flat, with a maximum of 500 kW for the whole society. So a 60-flat society can claim subsidy on up to 180 kW. This cap includes any systems individual residents have already installed.
Do we need approval from all residents?
You don’t need every single resident to sign. Most societies pass a resolution through the managing committee or at the AGM, as per their bylaws. We give you a simple proposal to share with members.
Will solar panels block the terrace or damage the roof?
No. We use elevated, zero-drill mounting, so there are no holes in the slab and the space underneath stays usable. Water tanks and service areas remain fully accessible.
How much can a society save with solar?
Most societies cut their common-area electricity bill by 60% to 80%. A 100 kW system, for example, can save around ₹85,000 a month depending on your tariff.
How long does apartment solar power installation take?
Installation usually takes 5 to 10 days for a society system. The full timeline, including approvals and net metering, is typically 4 to 8 weeks.
Is net metering available for apartments in Noida, Greater Noida and Ghaziabad?
Yes, grid-connected rooftop solar is allowed for residential societies in UP. We file the application with NPCL or PVVNL and coordinate the meter installation for you.
