Solar Subsidy for Housing Societies and Apartments in India 2026: Complete Guide

Why apartments are different from standalone homes
If you live in a flat, you cannot simply apply for PM Surya Ghar subsidy the same way a standalone homeowner does. The rooftop of your apartment building is common property. It belongs to all flat owners collectively, not to any individual. This means an individual flat owner cannot install solar panels on the rooftop independently and claim subsidy.
The solution is a collective housing society application, where the Residents Welfare Association (RWA) or Apartment Owners Association applies as a unit. Individual flat owners then benefit from reduced common area electricity costs and, depending on how the system is structured, reduced individual electricity bills as well.
Two models: common area solar vs individual flat solar
Subsidy amounts for housing society solar
The PM Surya Ghar subsidy structure applies to housing societies the same way it applies to individual homes, but calculated per residential connection included in the system. Here is how it works:
A housing society with 20 flats, each with a 2 kW allocation, could receive up to Rs 12,00,000 in total central subsidy. The exact eligibility depends on how the system is structured, how connections are allocated, and your state DISCOM’s specific rules for group net metering.
Step-by-step process for housing society solar application
Hold a general body meeting. Pass a formal resolution authorising the RWA or AOA to apply for rooftop solar on behalf of all residents. This resolution is a mandatory document for the DISCOM application.
Contact 2 to 3 DISCOM-empanelled installers for a rooftop survey. They will assess available shadow-free area, structural load capacity, and ideal system size for your building.
Common area only, individual flat allocation, or hybrid. System size depends on available rooftop area and how many connections will be included. Get quotes for each option.
The RWA secretary or authorised member applies using the society’s registered electricity connection number. Individual flat connections are linked in the system if going for the individual allocation model.
DISCOM reviews the technical proposal. For multi-connection systems the approval process takes longer than individual applications. Plan for 30 to 60 working days.
Same as individual process but DISCOM inspection is more detailed for larger systems. Net metering application follows within 30 days of installation completion.
Subsidy is credited to the bank account linked to each individual Aadhaar-verified connection. The society account receives it for the common area component, individual flat owners receive it for their allocated kW.
Common area solar: what it covers and what it saves
For societies that want the simplest route, common area solar is the most practical starting point. The solar system powers electricity used in shared spaces and saves money from the society’s maintenance collection.
Lifts and elevators
Typically the largest single common area electricity consumer in a mid-rise building.
Water pumps
Overhead tank pumping runs during peak solar hours, ideal solar load match.
Corridor and lobby lights
LED lighting on solar further reduces the common area bill.
CCTV and security
Security systems run 24 hours, and daytime solar powers them directly.
Garden and landscape
Irrigation systems and garden lighting during day hours.
Lower maintenance levy
Reduced common area electricity bill directly lowers society maintenance charges.
