Solar Panels for Apartments in Hyderabad — Yes, It's Possible
The most common myth in apartment solar: "I live in a flat, I can't go solar." Wrong. Two distinct paths exist — and one of them can be started this week without any society approval.
The Misconception — and the Reality
Most Hyderabad apartment residents assume solar is only for independent houses with their own rooftop. This is understandable — most solar marketing targets homeowners. But it leaves out a significant portion of Hyderabad's population living in apartments, gated communities, and multi-storey buildings across Gachibowli, Kondapur, Kukatpally, Madhapur, and Miyapur.
The reality is that there are two workable paths to solar for apartment residents. The right one for you depends on whether you can get your housing society on board.
Your Two Solar Options as an Apartment Resident
- Panels installed on the shared apartment rooftop
- Powers common areas (lifts, lights, pumps) and individual flats
- Requires RWA / society approval and participation
- Connected to DISCOM grid (TSSPDCL / TSNPDCL) via net metering
- System sizes: 5 kW to 50 kW+ depending on units and roof area
- Eligible for PM Surya Ghar subsidy
- Strongest ROI — typically 4–6 year payback
- Smaller panels (100W–300W) mounted on your balcony railing or window
- Off-grid: powers fans, lights, phone charging, small appliances
- No DISCOM approval needed
- No roof access needed — entirely within your flat
- No subsidy available (off-grid systems are not eligible)
- Limited output — not a full electricity substitute
- Best for reducing bills partially without society involvement

Option 1: Society Rooftop Solar — How It Works
Society rooftop solar is a collective system installed on the apartment building's shared rooftop. The solar panels generate electricity that is first used to power common areas (lifts, corridor lights, water pumps, security cameras) — reducing the society's common electricity bill significantly. Depending on the system size and society's arrangement with DISCOM, excess generation can be credited proportionally to individual flat owners.
How Savings are Shared
There are two common models:
Common area offset model: Solar generation covers common area consumption first. Any surplus reduces the monthly maintenance charge for all flat owners proportionally. This is the simplest model and the most commonly adopted in Hyderabad apartments.
Individual net metering model: Each flat's proportional share of the solar output is credited to their individual DISCOM electricity meter. This requires a more complex DISCOM arrangement but gives each flat a direct bill reduction. This is more prevalent in smaller societies (under 20 units).
Eligibility and Subsidy
Society rooftop solar qualifies for the PM Surya Ghar Muft Bijli Yojana subsidy at ₹18,000 per kW for group housing. Individual flat owners can additionally register on the PMSG portal for their proportional share of the installation. We guide societies through the PMSG registration process — the paperwork is manageable and the subsidy is worth claiming.
A 24-unit society in Gachibowli installed 20 kW of rooftop solar on their building. Common area bill (lifts, lights, pump) dropped from ₹28,000/month to under ₹10,000/month. The ₹18,000/month saved is distributed across 24 flats, reducing each flat's monthly maintenance by ₹750. With PMSG subsidy of ₹3.6 lakh applied, the net society cost of ₹10.4 lakh pays back in approximately 4.8 years. System will generate savings for 22+ more years after that.

How to Convince Your Housing Society
Points to Raise at Your Next RWA Meeting
- Show the numbers: Present a specific proposal — system size, estimated cost, subsidy amount, payback period, and monthly savings per flat. Vague proposals rarely get approval; specific numbers always get attention.
- Start with common area savings: Frame it as a maintenance cost reduction, not a technology adoption. Every flat owner benefits from lower maintenance charges — nobody opposes that.
- Address the roof concern proactively: Show that proper mounting structures with waterproofing do not damage the roof. Offer a site assessment before any commitment.
- Present the subsidy clearly: Many RWA members don't know about PM Surya Ghar subsidy. A ₹3.6 lakh subsidy on a ₹14 lakh system (20 kW) is a strong incentive that changes the financial conversation.
- Propose a small pilot: If there's resistance, suggest a 5 kW pilot for common area only at low cost. A successful pilot always unlocks full society buy-in.
- Invite us to present: We regularly present to RWA meetings in Hyderabad — free of charge. A credentialed installer (TGREDCO Reg. TSRE260936) explaining the process in person is far more persuasive than a brochure.
Option 2: Balcony / Window Solar — What to Expect
Balcony solar (also called plug-in solar or portable solar) involves mounting small solar panels on your balcony railing, window sill, or terrace parapet — entirely within your flat's boundaries. The panels connect to a small battery (typically 1–3 kWh) that powers specific appliances like fans, lights, and device chargers.
What it Can and Cannot Power
A 200W balcony panel with a 1.5 kWh battery typically powers: 2 ceiling fans for 6–8 hours, LED lighting for a 2BHK for 8–10 hours, phone and laptop charging. It cannot replace air conditioners, water heaters, or washing machines — these draw far more power than a balcony system can deliver.
No DISCOM approval, no society approval, no roof access needed. A balcony solar setup can be installed in a single day. It reduces your electricity bill partially, gives you backup during short power cuts, and serves as a first step toward energy independence. If your society later adopts rooftop solar, the balcony system can be repurposed for backup storage.
Eligibility for PM Surya Ghar Subsidy — Apartments
The PM Surya Ghar Muft Bijli Yojana (PMSG) subsidy structure for apartments:
- Individual flat with independent electricity connection and exclusive roof access: standard residential subsidy applies (₹30,000 for 1 kW, ₹60,000 for 2 kW, ₹78,000 for 3 kW+)
- Society rooftop system for group housing: ₹18,000 per kW (up to 500 kW)
- Balcony / off-grid systems: not eligible for any subsidy
- Individual flat registration under PMSG for a shared society system: possible with proper DISCOM net metering configuration — we guide societies through this
Ground reality check: Subsidy eligibility, exact amounts, and DISCOM configuration requirements vary case to case. We strongly recommend a free consultation before making any decisions. We assess your specific building, electricity accounts, roof area, and DISCOM feeder capacity before recommending a path.
Frequently Asked Questions
Can one flat install solar on the shared apartment roof?
A single flat cannot independently install solar on the shared roof without written consent from the RWA and all other flat owners who have access rights to the roof. The roof is common property. If you want individual solar as a flat owner, balcony panels (off-grid) are the practical alternative. For on-grid solar with DISCOM net metering, the whole society needs to participate.
Does apartment solar affect my individual electricity bill?
Yes, but differently depending on the system type. Society rooftop solar reduces the common area electricity bill (lifts, lights, pumps) and the savings are distributed to flat owners, reducing maintenance charges. If the society opts for individual net metering per flat, each flat's bill is reduced proportionally. Balcony / off-grid solar directly offsets consumption for appliances connected to that system.
How much does society rooftop solar cost in Hyderabad?
For a typical 24-unit apartment with 20 kW of rooftop solar, the total installed cost is approximately ₹12–15 lakh before subsidy. PM Surya Ghar subsidy for housing societies is ₹18,000 per kW (up to 500 kW). After subsidy on a 20 kW system, the net cost is approximately ₹8.4–11.4 lakh, shared across 24 flats — roughly ₹35,000–47,000 per flat with a 4–6 year payback.
Does an apartment society qualify for PM Surya Ghar subsidy?
Yes. Apartment housing societies qualify for PM Surya Ghar Muft Bijli Yojana subsidy at ₹18,000 per kW (up to 500 kW) under the group housing category. Individual flat owners can also register separately on the PMSG portal for their proportional share. The exact subsidy structure depends on how the DISCOM net metering is configured — we guide societies through the optimal registration approach.
How long does society rooftop solar installation take?
From society approval to commissioning, society rooftop solar typically takes 45–75 days. This includes DISCOM application (15–30 days), physical installation (2–5 days depending on system size), and DISCOM net meter commissioning (20–40 days). The longest part is often getting society approval and collecting documents from all flat owners — once that is done, the installation itself is fast.
