The easiest way is to check your monthly electricity bill. A typical Indian household consuming 300-400 units/month needs a 3 kW system. Our calculator helps you find the exact size based on your consumption, roof area, or specific appliances.
Approximately 80 sq ft of shadow-free roof area is needed per 1 kW with standard 540W Mono PERC panels. A 3 kW system needs about 240 sq ft, and a 5 kW system needs about 400 sq ft.
Yes, but for residential systems with net metering in UP, it's recommended to size the system at 80-100% of your consumption. Excess generation is credited at APPC rate (₹3-4/unit), which is much lower than the retail tariff (₹5-7/unit).
Key factors include monthly electricity consumption, available shadow-free roof area, roof orientation (south-facing is ideal), local solar irradiance (5.2 kWh/m²/day in UP), and whether you have net metering.
