Approximate output benchmark: 1 kW rooftop solar generates about 120 units per month in typical Indian conditions.
Only 75% of shadow-free roof is considered usable to account for spacing, setbacks and maintenance access.
Indicative residential subsidy is applied using common PM Surya Ghar slabs up to 3 kW, with a practical cap beyond that.
Annual generation includes a derating factor for real-world system losses.
