Sizing, Net Billing & Installation
Size the system to your bill, not to your roof. Under net billing your exported units earn roughly Rs 11/kWh against the Rs 23.57–48 you pay to buy, so self-consumption and storage now beat export. These guides cover the DISCO application, kW-by-kW system costs, the 40-point install checklist, solar appliances, and agricultural pumping.
