PM Surya Ghar for RWA & Housing Societies: ₹18,000/kW Subsidy Explained

Does your society’s maintenance bill keep climbing because of the common-area electricity charge?

If you sit on the managing committee of an apartment complex anywhere in India — Bengaluru, Pune, Delhi NCR, Kolkata, Siliguri, or a smaller city — you already know the pain: the lift, the corridor lights, the water pumps, the basement ventilation, the gate — none of it stops running, and none of it is billed to any one flat owner. It shows up every month as a shared line item, and residents grumble about it at every AGM.

Most RWAs and Group Housing Societies (GHS) assume rooftop solar is a residential, single-home product — something for the neighbour with an independent house, not for a 40-flat complex with a shared terrace and a dozen stakeholders to convince. That assumption is costing societies real money. Under the PM Surya Ghar: Muft Bijli Yojana, the Government of India has a dedicated, separate subsidy track specifically for common-area solar on Group Housing Societies and Resident Welfare Associations — ₹18,000 per kW, available on top of (and separate from) whatever individual flat owners claim for their own connections. This is a central scheme, uniform across every state, so it applies whether your society sits under BESCOM, MSEDCL, BSES, TANGEDCO, WBSEDCL, or any other DISCOM in the country.

You are not alone in not knowing this. Most societies we talk to across India have never had this route explained to them by a vendor, because most residential solar installers are set up to sell one rooftop, one homeowner, one subsidy application at a time — not a multi-stakeholder society project. This guide explains exactly how the RWA subsidy works, what it’s worth to your specific society, and how the application actually gets done.

Why RWAs Should Be Looking At This Now

1. The scheme is uncapped by state and actively disbursing. PM Surya Ghar’s 2026-27 budget allocation keeps the central subsidy pipeline open, with the scheme targeting 1 crore households by March 2027. There is no indication the ₹18,000/kW RWA slab is being phased down.

2. Common-area bills are pure waste from a solar perspective. Lift motors, corridor and staircase lighting, water pumps, and CCTV/security systems draw power through the day and evening — a load profile that a rooftop solar system, even without battery backup, offsets well because a meaningful share of it runs during daylight hours (pumps, standby loads) and net metering banks the rest.

3. DISCOM tariffs for societies are rising across the country. Commercial and higher-slab domestic tariffs applied to society common-area connections have moved upward in recent tariff orders in most states, and a fixed monthly common-area bill with no solar offset only gets more expensive with each revision, regardless of which DISCOM your society falls under.

4. EV charging is now an explicitly eligible common-area load. With more residents buying electric two-wheelers and cars, societies that add EV charging points can fold that load into the same RWA-subsidized system rather than treating it as a separate unbudgeted expense.

5. Net metering plus RWA subsidy materially changes the maintenance math. A system sized correctly against common-area consumption can turn what is currently a fixed monthly cost into a near-zero one, with the subsidy covering a substantial share of the upfront capital.

6. Financing removes the “who pays the upfront cost” objection. Collateral-free solar loans through public sector banks mean a society doesn’t need to collect a lump-sum special contribution from every flat owner before installing.

Understanding the RWA/GHS Subsidy: How ₹18,000/kW Actually Works

The Core Structure

Under PM Surya Ghar, a Group Housing Society or Resident Welfare Association applying as a society, for a system that powers shared common-area loads, is eligible for a Central Financial Assistance of:

The “3 kW per dwelling unit” figure is a notional ceiling used to calculate your society’s maximum eligible capacity — it caps how large a system the RWA subsidy will support, not a mandate that you must install that much. A society decides its actual system size based on real common-area consumption, then claims the subsidy on whatever capacity it installs, up to that ceiling.

This Is Separate From (And Stacks With) the Individual Homeowner Subsidy

This is the part most managing committees get confused about, so it’s worth stating plainly: the RWA subsidy and the individual flat-owner subsidy are two different applications, filed by two different applicants, for two different rooftops or roof-sections.

A resident who has an individually-metered rooftop portion (with a valid NOC) can claim their own ₹78,000 subsidy for their flat’s connection, while the society separately claims ₹18,000/kW for the common-area system on the same building. Both routes are documented on the National Portal, and neither displaces the other. If your society has residents interested in individual rooftop systems as well, that’s worth planning at the same site-survey stage so roof space is allocated sensibly between the two applications rather than creating a conflict later.

Real Numbers: What Your Society Could Claim

Disclaimer: The figures below are illustrative estimates based on typical common-area load patterns and indicative 2026 system pricing in India. Actual system costs vary by state, component brand, and local installation conditions. Your society’s actual eligible capacity depends on your sanctioned common-area load, available shared roof area, and DISCOM feasibility approval. Get a site-specific assessment before budgeting.

Example 1: 20-Flat Mid-Rise Society, Tier-2 City

• Dwelling units: 20 → notional cap: 60 kW
• Actual common-area load (2 lifts, corridor lighting, 2 water pumps): recommended system size ~8 kW
• Subsidy: 8 kW × ₹18,000 = ₹1,44,000
• Approximate system cost before subsidy: ₹5.6 lakh
• Net cost after subsidy: ~₹4.16 lakh, shared across 20 flats as a one-time contribution or financed via society loan

Example 2: 50-Flat Complex With EV Charging, Metro City

• Dwelling units: 50 → notional cap: 150 kW
• Common-area load plus 6 EV charging points for residents: recommended system size ~20 kW
• Subsidy: 20 kW × ₹18,000 = ₹3,60,000
• Approximate system cost before subsidy: ₹13.5 lakh
• Net cost after subsidy: ~₹9.9 lakh

Example 3: 100-Flat Large Township Cluster, Suburban Region

• Dwelling units: 100 → notional cap: 300 kW
• Common-area load across multiple towers, shared lift banks, and STP/pump loads: recommended system size ~45 kW
• Subsidy: 45 kW × ₹18,000 = ₹8,10,000
• Approximate system cost before subsidy: ₹28-30 lakh
• Net cost after subsidy: ~₹20-22 lakh, typically financed through a collateral-free society solar loan and repaid from the savings on the common-area bill

These are planning-stage estimates, not quotes. The final subsidy amount is fixed by the capacity your DISCOM approves and your society actually commissions, and system pricing varies by component brand, structure type, and site conditions.

What Common-Area Loads Actually Qualify

Not every society expense is an eligible “common area” load under this scheme. Loads that are typically covered include:

• Passenger and service lifts
• Corridor, staircase, and compound lighting
• Water pumps (overhead tank, borewell, STP)
• Basement and parking ventilation systems
• Security systems, CCTV, and intercom/gate infrastructure
• EV charging infrastructure for resident vehicles

Loads billed individually to specific flats or shops (retail units within a mixed-use complex, for instance) are not part of the common-area application — they fall under separate individual or commercial connections, which is why accurate metering and load segregation matter at the application stage.

System Sizing: How Much Solar Does Your Society Actually Need?

There’s no single “right” system size — it depends on your society’s sanctioned common-area load and daytime consumption pattern. As a working reference:

A proper site assessment measures your actual sanctioned load (from your DISCOM bill), roof area available for the RWA installation after accounting for any individual flat-owner systems, shading from adjacent structures, and structural load-bearing capacity — particularly relevant for older buildings before adding rooftop weight.

Roof Rights, NOCs & the Application Process for Societies

A society application moves through the same National Portal (pmsuryaghar.gov.in) as an individual one, but with committee-level documentation:

1. Society resolution: A formal managing committee resolution authorizing the solar installation and naming an authorized signatory to file the application.
2. Registration proof: Society registration certificate under the applicable state societies/cooperative act.
3. Common-area electricity connection details: Consumer number and latest bill for the connection(s) that power shared loads.
4. Roof access confirmation: Documentation that the terrace/roof being used is common property under society control (not leased or under individual exclusive rights, unless separately carved out for this purpose).
5. DISCOM feasibility approval: Filed on the National Portal against the society’s common-area consumer number.
6. Vendor selection: Choose an MNRE-empanelled installer experienced with multi-stakeholder, RWA-scale projects — society installations involve coordination that a single-home system doesn’t (committee sign-offs, resident communication, shared-roof logistics).
7. Installation and net meter: DISCOM installs a bidirectional net meter on the common-area connection after commissioning.
8. Subsidy disbursement: Paid via DBT to the society’s registered bank account after commissioning certificate upload and DISCOM inspection, typically within 30-60 working days, though timelines can extend depending on your DISCOM’s processing pace.

Financing: Societies Don’t Need to Collect a Lump Sum Upfront

Many managing committees stall at this stage assuming every flat owner needs to contribute cash before work can begin. That’s not the only route. PM Surya Ghar is integrated with collateral-free solar loans through public sector banks (SBI, PNB, Bank of Baroda, Canara Bank, Union Bank, and others), and societies can:

• Take a society-level loan against the projected common-area bill savings
• Collect a smaller one-time special contribution per flat, with the loan covering the balance after subsidy
• Structure repayment so the EMI is offset by (or lower than) the current common-area electricity bill, making the transition cash-flow neutral or positive from month one

This is worth raising early in committee discussions, since financing structure is often the actual blocker to getting a resolution passed — not resident opposition to solar itself.

Frequently Asked Questions

1. Can our society claim the RWA subsidy if some flat owners have already installed individual rooftop systems? Yes. The RWA subsidy applies to the society’s common-area system specifically. Individual flat-owner systems are separate applications and don’t reduce the society’s eligibility, provided roof space is properly allocated between the two.

2. What is the maximum subsidy our society can receive? ₹18,000 per kW, up to a system size that is the lower of (a) 500 kW absolute cap, or (b) 3 kW notional per dwelling unit in your society.

3. Who actually applies — the managing committee or individual residents? The society/RWA, as a registered body, applies through its authorized signatory. Individual residents are not part of this specific application.

4. Does the subsidy cover EV charging points for residents? Yes, EV charging infrastructure for common/shared use is an explicitly eligible common-area load under the RWA/GHS subsidy category.

5. Can a rented flat’s owner or occupant apply for the individual subsidy separately? No — the PM Surya Ghar individual household subsidy requires proof of ownership or the equivalent occupancy right specified by the scheme; tenants alone are not eligible to apply in their own name.

6. What if our society doesn’t have a large open terrace? Solar can be distributed across multiple smaller roof sections, stilted/podium structures, or covered parking canopies, subject to a site survey confirming structural feasibility and DISCOM approval.

7. How long does DISCOM feasibility approval typically take for a society application? This varies significantly by DISCOM workload and documentation completeness; societies should expect it to take longer than a single-home application given the additional verification of common-area load and registration documents.

8. Is there a minimum number of flats required to apply? There’s no fixed minimum flat count in the scheme structure itself, but very small societies may find the notional capacity cap (3 kW × flat count) makes the system size — and therefore the subsidy — modest relative to project overheads. A feasibility assessment will clarify whether it’s worthwhile for your specific society.

9. Does our society need to be a registered cooperative housing society, or does an informal RWA also qualify? Applications require a registered society/association under the applicable state act; check your specific registration status before applying, as informal or unregistered resident groups may face documentation hurdles.

10. What happens to the subsidy if our sanctioned common-area load changes after installation (e.g., we add more lifts later)? The subsidy is disbursed against the capacity commissioned and approved at the time of your application; expanding the system later would typically require its own separate feasibility and application process for the additional capacity.

11. Can the society subsidy be used for a diesel-generator-backup hybrid system instead of pure grid-tied solar? The central subsidy structure is built around grid-connected rooftop solar with net metering; battery storage or hybrid backup components are typically additional costs outside the subsidy calculation, though they can still be added to the system design.

12. Who owns the system — the society or individual flat owners? The system installed under the RWA/GHS application is an asset of the society, since it’s applied for, funded (net of subsidy), and maintained by the society as a body.

13. Does every flat owner need to individually consent, or is a committee resolution sufficient? This depends on your society’s own bye-laws and applicable state cooperative/society act requirements for capital expenditure decisions — consult your society’s legal framework, as requirements vary.

14. What warranty applies to a society-scale installation? Reputable installers provide manufacturer warranties on panels (typically long-term performance warranties) and inverters, plus a separate installation/workmanship warranty from the EPC contractor — confirm both in writing before signing.

15. How is the system maintained, and who bears that cost? Ongoing operations and maintenance (cleaning, inverter servicing, monitoring) is typically the society’s responsibility post-installation, either self-managed or through an AMC (Annual Maintenance Contract) with the installer — factor this into your society’s long-term maintenance budget alongside the electricity savings.

16. Do societies in different states or under different DISCOMs apply the same way? The central PM Surya Ghar subsidy structure is uniform nationally; the DISCOM-side feasibility and net-metering process may have minor procedural differences between, say, BESCOM, MSEDCL, BSES, TANGEDCO, or WBSEDCL, so confirm current local procedure with your chosen installer.

17. Is there a deadline to apply for the RWA subsidy? The scheme runs toward a 2027 national target and remains open at time of writing, but scheme terms, caps, and timelines are set by MNRE and subject to revision — always verify current status on pmsuryaghar.gov.in.

18. What if part of our society’s roof is under a mobile tower lease or similar third-party arrangement? That portion would typically need to be excluded from the solar layout unless the lease terms and structural assessment confirm it can be shared, which needs to be resolved before finalizing system design.

Why Housing Societies Choose SolarLogix

• Presence across multiple Indian states — teams that understand state and DISCOM-specific processes, not a one-size-fits-all national call centre.
• End-to-end subsidy handling — we help your society prepare the registration documentation, file the DISCOM feasibility application, and follow through to DBT disbursement, rather than leaving your committee to navigate the National Portal alone.
• Transparent, written quotes — no verbal promises on subsidy timelines or savings; every number is documented before you sign.

Solar for Societies Across India

Metro high-rises: Dense societies with multiple lift banks, larger pump systems, and higher common-area consumption are strong candidates for the higher end of the subsidy scale, and often have the roof or podium area to support it.

Tier-2 and tier-3 city societies: Mid-rise complexes where common-area lift and pump loads are a growing share of maintenance costs — a segment where the RWA subsidy has an outsized impact on relatively smaller society budgets.

Large township clusters: Multi-tower developments benefit from the 500 kW cap headroom, allowing significantly bigger common-area systems than a typical standalone apartment block.

Hill and terrain-variable regions: Societies in hilly or high-wind areas need extra attention to structural assessment and panel orientation given terrain and weather conditions, which a proper site survey accounts for.

Emerging residential developments: Newer housing society projects are increasingly building solar into common-area planning from the outset rather than retrofitting later, wherever in India they’re located.

Wherever your society is located, the central subsidy structure, eligibility rules, and application process on the National Portal remain the same — only the local DISCOM’s feasibility and net-metering procedures vary slightly from state to state.
