Solar for societies and RWAs

Cut common-area bills for every flat.

Lifts, pumps, corridor lights and the clubhouse run all day, which is exactly when the sun is up. A rooftop plant on your towers can bring down the maintenance charge for every resident, with ₹18,000 per kW in central subsidy.

Why societies are a strong fit for solar

Common-area power in a group housing society is billed at a commercial or bulk rate in many DISCOMs, and most of it is used in daylight. That combination means solar units replace expensive grid units almost one for one. Tower roofs are also large, flat and shade-free compared to individual homes.

Item	What applies
Central subsidy	₹18,000 per kW for common facilities, including EV charging
Size limit	Up to 500 kW, at 3 kW per house, including residents' own plants
Output	About 1,400 to 1,450 units per kW a year in NCR
Metering	Net metering; group and virtual net metering in Delhi and Punjab
Delhi extra	State support for GHS and RWA common facilities under the Delhi Solar Policy

A worked example

Take a 300 flat society in Noida or Gurugram with a 100 kW plant on its tower roofs. It makes roughly 1.4 lakh units a year. At a common-area rate of about ₹7 to ₹8 a unit, that is ₹10 to 11 lakh a year off the society's bill, or about ₹3,000 to ₹3,700 per flat per year. The central subsidy alone is ₹18 lakh on 100 kW.

Your numbers will differ. We work from your last twelve months of common-area bills, your roof drawings and your sanctioned load, and give the committee a written estimate.

How we work with a managing committee

Bill and roof review. Send us twelve months of common-area bills and tower drawings. We do a site walk with the facility manager.
Committee proposal. A short document with plant size, layout per tower, expected units, subsidy, payback and options (capex, EMI or RESCO).
AGM support. We attend the general body meeting if you want, and answer residents' questions plainly.
Approvals and portal. PM Surya Ghar registration as GHS or RWA, DISCOM feasibility and net metering.
Installation in phases. Tower by tower, with safety barricading, lift and terrace access schedules agreed with the FM team.
Monitoring dashboard. One view of every inverter for the committee and the FM, with monthly reports.

Roofs, waterproofing and fire safety

Societies worry about three things: leaks, fire and access. We use ballast or chemical anchors that do not break the waterproofing layer where possible, keep walkways clear for maintenance and fire access, run DC cables in metal trays, and fit DC isolators and surge protection at every inverter. All of this is in the drawings the committee approves.

Capex, EMI or zero investment

Societies with a healthy sinking fund usually buy the plant outright and get the subsidy. Others take a term loan and pay it from the savings. A third route is RESCO, where a developer owns the plant and sells units to the society below the grid rate for a fixed term. We set out all three for the committee. See solar loans and EMI.

We have done 300+ installations across NCR and the tricity. Ask for a society proposal, and see the local rules for Noida, Greater Noida, Gurugram and Delhi.

Common questions

How much subsidy does a housing society get for solar?

Under PM Surya Ghar, a group housing society or RWA gets ₹18,000 per kW for solar that powers common facilities, including EV charging. The limit is 500 kW, counted at 3 kW per house, and it includes any systems residents have already put up on their own.

Does a society need an AGM resolution for solar?

Usually yes. Most societies need a managing committee approval and a general body resolution to use common roof space and society funds. We prepare a proposal with expected savings, payback and roof drawings that the committee can present.

Can individual flat owners in a society get solar?

Sometimes. Virtual net metering, available in Delhi and Punjab, lets residents share the output of one common system across their own meters. Elsewhere the simpler route is a common-area system that cuts the maintenance charge.

What can a society's solar power run?

Lifts, water pumps, common lighting, the clubhouse, STP and EV chargers. These loads run during the day, which makes them a good match for solar.

Is there a zero-investment option for societies?

Yes, under a RESCO or power purchase model a developer installs and owns the plant and the society buys the units at a fixed tariff below the grid rate. It suits societies that do not want to spend from the sinking fund.
