Why 4-5 kW is the sweet spot for a Jaipur villa
PM Surya Ghar Yojana caps the central subsidy at ₹78,000 for any system 3 kW and above. So a 3 kW gets you the same subsidy as a 5 kW — but the 5 kW generates 65% more units. For a Jaipur villa consuming 700+ units/month, the 5 kW is the most economically efficient choice. A 4 kW is the right compromise for villas in the 500-700 units/month range.
Going above 5 kW makes sense ONLY if your monthly consumption is over 900 units — otherwise you generate surplus units that get credited at JVVNL APPC (₹3.5-4/unit) rather than at your residential tariff (₹7-9/unit).
