Solar for Apartments in Hyderabad — RWA Complete Guide
Updated March 2026 | Sri Ishaan Solar
Living in an apartment? You can still go solar — but the path looks different from an independent house, and being honest about that upfront saves a lot of wasted effort. The two real questions are: who owns the roof you'd put panels on, and whose electricity bill actually goes down. Answer those and the right approach becomes obvious. Here's how housing societies and individual flat owners in Hyderabad are doing it.
Two Options for Apartments
Option 1: Common Area Solar (RWA Decision)
- Solar powers common area (lifts, lights, water pumps, CCTV)
- RWA passes resolution → all members benefit
- Typical size: 10-50 kW depending on common area load
- Cost split equally among all flat owners
- Monthly maintenance fund savings: Rs 500-2,000 per flat
Option 2: Individual Flat Rooftop
- If you have exclusive roof access (top floor, penthouse)
- 1-3 kW system for your own consumption
- PM Surya Ghar subsidy applicable
- Need RWA NOC
Costs for Housing Societies
| System Size | Total Cost | Per Flat (50 flats) | Monthly Saving/Flat |
|---|---|---|---|
| 10 kW | Rs 5-6 lakh | Rs 10,000-12,000 | Rs 300-500 |
| 25 kW | Rs 12-15 lakh | Rs 24,000-30,000 | Rs 800-1,200 |
| 50 kW | Rs 22-28 lakh | Rs 44,000-56,000 | Rs 1,500-2,000 |
The Real Hurdle: Getting Your RWA to Say Yes
The technical side of apartment solar is the easy part. The genuine bottleneck, in almost every society we've worked with, is the committee decision — because a common-area system is a shared capital expense, and shared expenses invite debate. What actually gets a resolution passed isn't a sales pitch; it's turning an abstract "green idea" into a line item on the maintenance bill that everyone can see shrinking.
The argument that lands is the maintenance-fund one. Lifts, corridor lights, water pumps, and CCTV run on the society's common meter, and that bill is paid out of everyone's monthly maintenance. When solar cuts that bill, the saving flows straight back into the maintenance fund — which means either lower levies or more money for other repairs, without anyone paying extra. Framed that way, solar stops being a debate about the environment and becomes a debate about money the society is currently leaving on the table. Present the current common-area bill, the expected saving, and the roughly 4-5 year payback, and most committees move from "why would we?" to "why haven't we?".
