Is society NOC mandatory for rooftop solar in flats?

When the roof is common property or society bylaws require committee approval, yes — practical installs almost always need written NOC before DISCOM feasibility and PM Surya Ghar commissioning. Requirements vary by state RERA, society bye-laws, and DISCOM forms.

What documents does an RWA usually ask for before solar NOC?

Common requests: structural load certificate, vendor empanelment proof, panel layout drawing, waterproofing warranty, insurance/indemnity clause, cable routing plan, and draft NOC on society letterhead signed by secretary and president.

How long does society approval for solar take?

Informal committee review can take 2–6 weeks; AGM-backed resolutions may wait until the next quarterly meeting. Budget 1–3 months for society steps in contentious buildings, before DISCOM and install timelines.

Why societies care — beyond “solar is good”

Managing committees are liable for common property. Their questions are predictable:

Will panel mounts overload the slab designed for water tanks only?
Who fixes a leak if a J-bolt pierces the waterproofing membrane?
Will cables run through common shafts — fire safety and aesthetics?
If one flat sells, does the plant stay or get dismantled?
For RWA-wide plants: how is CFA credited and savings split fairly?

Address these upfront and NOC meetings go faster than leading with “government subsidy.”

Two approval tracks

Track	Who applies	Typical committee ask
Individual flat (private terrace rights)	Flat owner on own domestic meter	Written NOC, structural OK, indemnity for waterproofing
RWA common-area plant	Society / association entity	AGM resolution, vendor contract, benefit-sharing policy, larger load certificate

Step-by-step — individual flat NOC

Read your allotment / sale deed. Note whether terrace is exclusive, common, or “exclusive use of common area.” That phrase changes everything.
Check society bye-laws. Some ban external fixtures; others allow with committee consent. Maharashtra, Karnataka, Delhi, and Gujarat RWAs often have ad-hoc policies — few had solar clauses before 2020.
Submit a written request to secretary with: proposed kW, panel layout (north/south, setback from tank), vendor name, empanelment proof, and structural certificate from a licensed engineer.
Offer indemnity language — owner (or vendor) bears waterproofing repair cost for penetration zones; society not liable for generation shortfall.
Committee meeting. Present 10 minutes; leave a one-page FAQ. Avoid debating brand wars in the lobby WhatsApp group first.
Written NOC on letterhead — signed president + secretary, society stamp, flat number, plant kW, validity date. Scan for DISCOM and pmsuryaghar.gov.in upload if required.
Only then sign vendor contract and apply for DISCOM feasibility — installing before NOC risks removal and subsidy loss.

Step-by-step — RWA / AGM resolution (common-area plant)

Form a small owner sub-committee (3–5 flats) to compare quotes — not one vendor’s friend on the MC.
Feasibility memo: shadow-free kW cap, common load profile (lifts, pumps, lighting), CFA at ₹18k/kW GHS rate vs individual paths.
Circulate agenda 14–21 days before AGM as bye-laws require; attach vendor comparison and draft resolution text.
AGM resolution items typically include: appoint vendor, approve roof use, authorize office-bearers to sign DISCOM / portal forms, and approve savings credit method (per flat fixed ₹, per sq ft, or against maintenance).
Post-AGM: registered minutes, bank resolution if CFA account needed, single point contact for DISCOM.

Subsidy framing: PM Surya Ghar guide. Equipment compliance: ALMM & DCR panels.

Documents RWAs commonly request

Structural stability certificate (stamped) for added dead load + wind load
Panel layout CAD or marked terrace photo with dimensions
Vendor MNRE / state empanelment letter
ALMM-listed module and inverter datasheets
Waterproofing method statement and warranty (typically 5–10 years on penetration work)
Third-party insurance or indemnity bond where committees insist
Decommissioning plan if owner sells or tenant vacates

When committees say no — and what helps

“Roof is common — you can’t touch it.” Propose a pilot section, third-party structural audit paid by owner, or shift to RWA-wide tender instead of one flat.
“Wait for uniform policy.” Offer to draft a society solar policy template other cities use — MC often lacks time to write one.
“Vendor X is our friend.” Insist on empanelment verification and ALMM modules regardless of relationship.
“AGM not until December.” For individual NOC, ask if MC can grant interim consent pending AGM ratification where bye-laws allow.

DISCOM and portal — where NOC fits

Many DISCOMs (including several in Maharashtra, Karnataka, Telangana, and NCR) ask for society NOC upload during net-meter application or commissioning inspection. PM Surya Ghar may reject CFA if roof-rights documents do not match the applicant name. Sequence matters: NOC → feasibility → install → inspection → CFA DBT, not the reverse.

Society NOC questions

Can the managing committee legally block solar entirely?

Depends on bye-laws, ownership rights, and state housing rules. Some top-floor owners with exclusive terrace rights have challenged blanket bans — but litigation is slow and expensive. Negotiation with structural proof is usually faster. This is not legal advice; consult local counsel if blocked unfairly.

Does NOC mean the society owns my panels?

Not unless the resolution says so. Standard individual NOC grants permission to install on common roof area allocated to your flat — ownership stays with you. Read the NOC text before signing.

Is a WhatsApp “ok” from the secretary enough?

Treat informal chat as progress, not proof. DISCOM and subsidy audits want signed letterhead NOC or registered AGM minutes. Follow up in writing.
