PM Surya Ghar
The society rule
What PM Surya Ghar pays a housing society or resident welfare association for a system on its common facilities, as the ministry publishes it.
PM Surya Ghar, housing societies and RWAs
Rs 18,000 per kW
- Applies to
- The common facilities of a housing society or resident welfare association: lifts, pumps, corridor lighting and the clubhouse.

The assistance is paid against the size the DISCOM approves, into the society's account, after the net meter is in and the commissioning report is on the portal. Your estimate above already applies this rule to the bill you set.
The committee
How a society decides
Four things the committee settles before anyone climbs to the roof, in plain terms.
The resolution
The managing committee resolves to put solar on the common roof and names who signs. The application goes in the society's name, on the common-services connection; no flat owner's account is touched.
The common meter
The system feeds the meter that bills the lifts, pumps, corridor lights and the clubhouse. The DISCOM swaps that meter for a net meter, and the generation is set against that one bill.
How the saving is shared
The saving lands on the common-services bill, which every member already pays through the maintenance charge. The committee decides whether the charge comes down or the difference goes to the corpus; the system needs no rule per flat.
One roof, one application
We survey the roof once, with the tanks, lift rooms and existing plant drawn in, and file one application for the whole roof. The committee signs; the DISCOM deals with one account.
Net metering
Who files what with the DISCOM
Six steps from the application to the assistance, each marked with who does it. The same steps as a home, with the society as the applicant.
- Leo files
Application on the national portal and to the DISCOM
Your electricity account, identity and ownership documents, and the bank account the assistance is paid into. Prepared by us, signed by you.
- The DISCOM
Feasibility approval
The utility checks the connection and the load and approves the size. We follow it up until it lands.
- Leo files
Installation by a registered vendor
Structure, panels, inverter, cabling, earthing and lightning protection, to the written proposal.
- Leo files
Net-metering application and inspection request
Filed with the utility once the system is installed, with the test reports.
- The DISCOM
Inspection and the net meter
The utility inspects the installation and installs the net meter. You are present; nothing to file.
- Leo files
Commissioning report and the assistance
The commissioning report goes on the portal; the assistance is released to the bank account you gave in step one.
Put a survey in front of the committee.
One engineering visit to the common roof and the supply, then a written proposal the committee can vote on.
