Direct answer: Apartment and RWA rooftop solar in Bangalore is usually a common-area conversation first: lifts, pumps, lighting, clubhouse and other shared loads on the society’s BESCOM connections. A published scheme figure cited for common facilities is ₹18,000 per kW, and that figure must be checked as a scheme rule at application. BESCOM is actively seeking RWA support to boost rooftop solar adoption in Bengaluru. Society committees can start with a common-area bill review and roof survey on Call / WhatsApp +91 7975009078.
Why apartments should start with common-area load
An apartment roof is shared, and so are many of the loads beneath it. The clearest first case is usually the meter or meters that serve common services, because the committee can read those bills, approve a project for shared benefit and plan access for installation and maintenance. Individual flats, common areas and any separate commercial connections inside a complex may sit on different meters, so Eltron maps the connections before sizing anything.
The ₹18,000 per kW common-facilities figure
A BAF primer cited in Eltron’s research notes ₹18,000 per kW for common facilities, up to 500 kW at 3 kW per house. Treat that as a scheme rule to check at application, not as a confirmed price or entitlement for your society. Eltron will verify the current rule, cap and eligibility route for your apartment’s connection type before the committee relies on the figure in a budget or member approval.
What a society committee should bring to the first meeting
- Common-area BESCOM bills in units and rupees for the past year, where available
- A list of common loads: lifts, water pumps, sewage treatment, lighting, clubhouse, gym and EV-charging plans
- Terrace plan, roof age and waterproofing status, and any areas already reserved for tanks, ducts or amenities
- Sanctioned load and meter details for each common connection
- Committee approval route, member communication plan and who will sign for the society
- Access rules for installation, cleaning and future maintenance
A practical RWA process
- Review common-area bills and separate must-run daytime loads from night-heavy loads.
- Survey every usable roof block, including shadow, structure, waterproofing and safe access.
- Agree the design boundary: which meters the solar system will serve and what happens to surplus generation under the applicable DISCOM route.
- Confirm subsidy and net-metering eligibility for the society’s connection type, then prepare committee and member approvals.
- Apply through the relevant portal and BESCOM process, install, complete inspection and synchronisation, and set a cleaning and maintenance access schedule.
Questions committees usually ask before approval
Committees usually need to know who owns and insures the system, how roof waterproofing is protected, what happens when a terrace needs repair, how generation will be reported to members, and who coordinates cleaning and service visits. Put those points in the proposal and minutes before work begins. Eltron includes 5 years of free maintenance in its residential offer, and the committee should confirm in writing how that maintenance access and scope will work for a shared apartment roof.

Members who also want a system for an independent home can read the rooftop solar cost in Bangalore hub and the guide to rooftop solar in Bengaluru. For the society project itself, use the common-area bills rather than individual flat bills to start the sizing conversation.

FAQ: Apartment and RWA solar in Bangalore
Can an apartment society install rooftop solar for common areas?
That is usually the first route to assess, starting with the BESCOM meters that serve lifts, pumps, lighting and other shared loads. Eltron maps the meters and roof blocks before sizing a system.
What subsidy figure should an RWA use in its first budget?
A published primer cites ₹18,000 per kW for common facilities, up to 500 kW at 3 kW per house. The committee should treat that as a scheme rule to check at application and confirm eligibility before approving a budget.
Who should attend the first Eltron meeting?
Bring the committee members who can approve a survey, the facility manager, and the person who holds common-area BESCOM bills, meter details and terrace access information.
Prices and scheme figures on this page are indicative only. The ₹18,000 per kW common-facilities figure is a scheme rule to check at application, and your society’s final quote, subsidy eligibility, cap and BESCOM process are confirmed after a common-area bill review, roof survey and application check.
