3kW vs 5kW Solar for a Home in Zahirabad: Which Should You Choose?
Most homes in Zahirabad (also spelled Zaheerabad) choose between 3 kW and 5 kW. Both earn the full ₹78,000 PM Surya Ghar subsidy, so the choice comes down to your monthly bill and roof. As a rule: around ₹3,000–3,600 a month suits 3 kW; around ₹5,000–6,000 suits 5 kW.
The Short Answer: Choose by Your Bill
3 kW: ₹2,10,000 project cost, ₹1,32,000 after subsidy, 360–450 units a month, about ₹3,000–3,600 saved each month (₹36,000–43,000 a year), 180–195 sq ft of roof, payback about 3–4 years.
5 kW: ₹3,25,000 project cost, ₹2,47,000 after subsidy, 600–750 units a month, about ₹5,000–6,000 saved each month (₹60,000–72,000 a year), 300–325 sq ft of roof, payback about 3.5–4 years.
The subsidy is the same ₹78,000 for both, so it covers about 37% of a 3 kW project and 24% of a 5 kW project. If your bill is closer to 3 kW territory, 3 kW gives the most subsidy per rupee spent; if your bill is higher, the extra 2 kW saves roughly double the money for about ₹1.15 lakh more net outlay. Roof space can also decide it: 3 kW needs around 120 sq ft less than 5 kW.
- Under ₹4,000 a month: 3 kW
- ₹5,000–6,000 a month: 5 kW
- Plan to buy an EV: lean to 5 kW
