Solar for a 2 BHK home
The short answer
A 2 BHK home running a fridge, TV, washing machine, fans and lights typically needs a 2 kW solar system — about ₹1,16,000 installed, ₹58,000 after subsidy, generating 230–250 units a month.

Why 2 kW: because 2 BHK consumption typically runs 180–250 units a month, and a 2 kW system generates 230–250 — right-sized without paying for capacity you can't consume.
What it runs: fridge, TV, fans, lights and washing machine, with an AC only occasionally in peak summer.
Roof needed: roughly 180–200 sq ft of shadow-free space.
Worth knowing: In an independent 2 BHK house this is straightforward. In a flat, you need exclusive terrace rights or society approval — flats go through the RWA track with different subsidy rules.
Subsidy: ₹60,000 under PM Surya Ghar (₹30,000/kW up to 2 kW, capped at ₹78,000 for 3 kW+, residential connections only) — credited after your DISCOM commissions the system.

My 2 BHK is a flat in a society — can I still install?
Only if you have exclusive rights to a terrace portion, or the society installs a shared system under the RWA track. Individual flats on a shared roof without terrace rights can't claim the individual subsidy.
2 kW vs 3 kW for a 2 BHK — which is right?
Check your bill, not the bedroom count. Under ₹2,000/month → 2 kW. ₹2,500–3,500 with an AC habit → 3 kW. The calculator gives the honest answer in 30 seconds.
