Sizing + payback estimate appears here.
Note on accuracy: This calculator returns an order-of-magnitude estimate using a 20% design margin and climate-based derating (15-30%). Real sizing for a tender or engineering proposal accounts for load profile, generation profile, ToD tariff structure, transformer ratings, and grid code requirements.
Cost figure (~₹30,000/kWh installed) is indicative for India 2026; actual price depends on chemistry, integration scope, and quantity. Payback is computed assuming ToD arbitrage spread of ₹6/kWh and 250 charge-discharge cycles per year — real cases vary widely.
