Sri Ishaan Solar — TGREDCO Reg. TSRE260936 · GSTIN 36AFXFS2132K1ZG · 100+ installations across Telangana since 2017
Hyderabad's west corridor — Kondapur, Manikonda, Gachibowli, Kukatpally, Miyapur and the belt around them — is dense with gated communities and high-rise apartment societies. Almost every solar company in the city pitches individual rooftops (3–10 kW homes). Very few walk an RWA's managing committee through what a society-level, common-area system actually looks like — the subsidy track is different, the net metering arrangement is different, and the ticket size (25–100 kW per deal) is an order of magnitude bigger than a single home. This page is written for that decision: the treasurer or managing committee member trying to figure out whether solar is worth putting on the AGM agenda.
- Subsidy track: GHS/RWA common-facility CFA — ₹18,000 per kW, up to 500 kW capacity per society (verified against MNRE/pmsuryaghar.gov.in guidelines, July 2026)
- Net metering: TGSPDCL Group Net Metering Arrangement, available for systems under 100 kWp on a society's common-area connection
- Typical deal size: 25–100 kW depending on society size and common-area load
- Areas we cover directly: Kondapur, Manikonda, Gachibowli, Kukatpally, Miyapur and the rest of Hyderabad's west corridor
What Group Net Metering Means for a Housing Society
A gated community's common-area load — lift motors, corridor and compound lighting, borewell/OHT water pumps, clubhouse and gym, security-cabin power — normally sits on its own DISCOM connection, billed separately from individual flats. Under TGSPDCL's Group Net Metering Arrangement, the society (registered as a Group Housing Society or RWA) can install rooftop solar against that common-area connection and net the generation against consumption on a single bidirectional meter.
Key points that matter to a managing committee, based on TGSPDCL's published rooftop solar net-metering guidelines:
- Category: Apartments/residential colonies fall under the LT-I (Domestic) or HT-VI (Townships & Residential Colonies) categories depending on the society's sanctioned load, and can use the Group Net Metering Arrangement for systems under 100 kWp.
- Single supply requirement: the society needs a common meter/single supply point for the common-area load that the solar system will be netted against — this is standard for most gated communities already.
- Billing: net export in a given month is credited to the society's account and carried forward against future bills. Any credit not adjusted during the year is settled twice annually (June and December) at the average power-purchase cost decided by TSERC for that year — it is not a instant cash payout.
- Minimum size: 10 kWp is generally the minimum for a net-metered rooftop system under these arrangements.
What this does NOT cover: group net metering nets the common-area connection only. Individual flat-owner meters are billed separately and are not automatically netted by a society-level system unless residents separately opt into virtual net metering arrangements on their own connections — a different, flat-by-flat process outside the scope of this page.
Common-Area Load Math — a Worked Example (Illustrative)
Every society's actual common-area consumption is different — the numbers below are industry-typical illustrative estimates for a mid-size complex, not a substitute for your society's actual last-12-months electricity bills, which is what we size against during the free site survey.
| Load | Typical count | Est. monthly units (kWh) |
|---|---|---|
| Passenger lifts | 4–5 lifts | ~1,800–2,500 |
| Borewell / OHT water pumps | 2–4 pump sets | ~1,200–2,000 |
| Common lighting (corridors, compound, basement) | — | ~1,000–1,500 |
| Clubhouse, gym, security cabin | — | ~500–1,000 |
| Estimated total common-area load | ~4,500–7,000 kWh/month |
At Hyderabad's ~4.5–5 peak sun hours/day, a 25 kW rooftop system generates roughly 3,300–3,700 kWh/month — enough to offset a meaningful share of a common-area load in this range, with the exact offset depending on how much of that generation lines up with daytime pump/lift usage vs evening lighting. This is why we size every society system against your actual TGSPDCL common-area bills, not a generic assumption.
A Worked 25kW Society Example
The table below shows how the numbers work for an illustrative 25 kW common-area system, using the verified ₹18,000/kW GHS/RWA subsidy rate. This is a planning illustration for the AGM — your society's exact quote follows the free site survey.
| Item | Value |
|---|---|
| System size | 25 kW |
| Approx. gross cost (₹11–13/W for this size band) | ₹28,00,000 – ₹32,50,000 |
| GHS/RWA subsidy @ ₹18,000/kW | ₹4,50,000 |
| Approx. net cost after subsidy | ₹23,50,000 – ₹28,00,000 |
| Est. monthly generation (~135 units/kW/month) | ~3,375 kWh |
| Est. monthly saving on common-area bill | ~₹27,000 – ₹34,000 |
| Approx. simple payback | ~6–8 years on net cost, before considering the society's 25-year panel life |
RWA Decision Checklist — What Your Society Needs
Before a managing committee can move from "let's look into solar" to signing a contract, these are the approvals and documents that typically need to be in place:
- Managing committee resolution — a formal resolution recording the committee's decision to explore/approve the installation and the expenditure involved.
- AGM approval (if required by your bye-laws) — many societies' bye-laws require a General Body resolution for capital expenditure above a threshold; check yours before budgeting a timeline.
- Terrace/roof rights confirmation — confirmation that the terrace is common property under the society's registration, or an NOC from whoever holds those rights if it's ambiguous.
- Structural safety certificate — a structural engineer's sign-off that the terrace can bear the panel + mounting-structure load; we coordinate this as part of the site survey.
- GHS/RWA registration proof — society registration documents needed to apply for the PM Surya Ghar GHS/RWA subsidy track.
- TGSPDCL group net metering application — feasibility request, single-line diagram, and MNRE-format documents submitted against the society's common-area connection. We prepare and file this.
- Common-area electricity bills (last 12 months) — the single most useful document for sizing the system correctly; bring these to the site survey.
- Vendor selection — most societies collect 2–3 quotes; ask any vendor for their TGREDCO empanelment number (ours is TSRE260936) since it's required for the subsidy claim.

Request a Society Presentation
We don't have a generic downloadable proposal template — every society's roof, common-area load, and bye-laws are different, so a real proposal only makes sense after we've seen your actual TGSPDCL common-area bills and terrace. What we can do quickly: come present to your managing committee or AGM, walk through the subsidy and net-metering process, and leave your treasurer with a written cost/savings estimate specific to your society.

Frequently Asked Questions
What subsidy does a gated community or apartment society get for solar?
Under PM Surya Ghar Muft Bijli Yojana, Group Housing Societies (GHS) and RWAs get ₹18,000 per kW Central Financial Assistance for common-facility solar, up to 500 kW per society (calculated at up to 3 kW per flat, inclusive of any individual resident systems). This is a separate track from the individual residential subsidy (a flat ₹78,000 for a single home's 3kW+ system) — don't confuse the two. Verified against MNRE/pmsuryaghar.gov.in guidelines as of July 2026; always re-confirm the rate at application time since CFA norms are revised periodically.
What is group net metering under TGSPDCL?
It's an arrangement that lets a society net its rooftop solar generation against its common-area connection (lifts, pumps, lighting, clubhouse) on a single bidirectional meter, available for systems under 100 kWp. Surplus export is credited and carried forward, with unadjusted credits settled twice yearly (June and December) at the TSERC-decided rate.
How much can a 200-flat society save on common-area electricity with solar?
It depends entirely on your society's actual common-area load. As an illustrative estimate only, a 200-flat complex's common-area load (lifts, pumps, lighting, clubhouse) often falls in a range that a 20–30 kW system can meaningfully offset — but we size against your real last-12-months bills, not assumptions.
What approvals does an RWA need before installing solar?
Typically a managing-committee/AGM resolution, confirmation of terrace/roof rights, a structural safety certificate, GHS/RWA registration proof for the subsidy application, and the TGSPDCL group net metering application. See the full checklist above.
