Societies get Rs 18,000 per kW. Most quotes get it wrong

A housing society is the largest single residential opportunity most EPCs will ever walk into, and the one they are most likely to quote wrong.

The reason is that people apply the household subsidy they know to a building that does not qualify for it. The society route is a different rate, a different cap, a different applicant and an extra equipment condition.

The four numbers that define the job

The rate is Rs 18,000 per kW, for common facilities including EV charging. Not Rs 78,000, which is the household cap for an individual home of 3 kW or more.

The ceiling is 500 kW for the society as a whole, calculated at 3 kW per house.

That 500 kW includes systems residents have already installed on their own. A society where forty flats have put up individual plants has already consumed part of its headroom, and nobody tells you this at the site visit.

The modules must be DCR, domestic content, to qualify for the incentive. That is a price input, not a footnote, and it constrains which stock you can use. The distinction between DCR and the ALMM lists is in DCR and ALMM List-II are not the same rule.

Put those together and a 100 kW common area system carries Rs 18 lakh of central assistance, which is a serious number to be vague about in a proposal.

The application mistake that kills deals quietly

The application must come from the RWA or the apartment owners association, as the society.

Individual flat owners who apply on their own using the society's rooftop address get rejected at the DISCOM feasibility stage. Not at the end, not with an explanation that reaches you, just rejected. If you have residents in a building applying individually, you are collecting future disappointment.

The fix is to reach the managing committee first and treat the residents as beneficiaries of one project rather than as forty separate sales.

What actually gets solarised

Be precise with the committee about what the system powers, because this is where expectations break.

The society subsidy is for common facilities: lifts, water pumps, corridor and basement lighting, STP, club house, security systems and EV charging points. That is common area load, billed to a common meter, paid from maintenance charges.

It does not put solar on a resident's individual electricity bill. A resident who wants that needs their own system on their own connection under the household route, within whatever roof space the society allocates.

If you do not say this in the first meeting, somebody in the AGM will assume otherwise, and you will be blamed for it later.

Sizing against maintenance, not against the roof

The right size for a society system is set by common area consumption, not by how much roof is available.

Get twelve months of common meter bills. Look at the load pattern: lifts and pumps run through the day, corridor lighting runs at night, and the balance between them decides how much of your generation is self consumed rather than exported. With net metering narrowing for larger consumers, that self consumption ratio matters more each year.

Then look at the roof honestly. Societies have water tanks, lift machine rooms, terrace gardens, mobile towers with their own lease income, and residents who use the terrace. The usable area is always smaller than the plan suggests.

The sale is a committee sale

Three things make the difference between a society proposal that closes and one that circulates for a year.

1. Write for the AGM, not for the engineer. The document has to survive being read aloud to a hundred owners, most of whom will focus on the maintenance charge. Lead with the monthly saving per flat, then the payback, then the technical detail in an annexure.
2. Name the money and the paperwork owner. Who funds it, whether from the sinking fund, a reserve or a loan, and who signs. Committees have terms; a proposal that outlives the committee that received it dies.
3. Put the subsidy timing in writing. Central assistance arrives after commissioning. A committee that has budgeted for it as a discount will have a problem at payment time, exactly as households do. The disbursement sequence is in the subsidy maths every EPC should know.

The short version

• Group housing societies and RWAs get Rs 18,000 per kW for common facilities including EV charging, up to 500 kW at 3 kW per house.
• That cap includes systems individual residents have already installed.
• Modules must be DCR to qualify.
• The application must come from the RWA or association. Individual applications at a society address get rejected at DISCOM feasibility.
• The system covers common area load, not residents' own bills. Say so in the first meeting.
• Size against twelve months of common meter bills, and against the terrace that is actually usable.
