Identify the electricity licensee
JBVNL, TSUISL, Tata Steel or another licensed supply area can have different application and metering workflows. Use the actual bill—not only the city name—to select the route.
Size from consumption and roof
Review monthly units, daytime use, shading, orientation, cleaning access and structure condition. Ask for realistic annual generation and a residual-bill estimate.
Show assistance separately
Use the applicable central CFA and do not add an unverified state top-up. Model gross payment, expected release and any loan prepayment as separate events.
Protect the long-term result
Include monitoring, cleaning, preventive inspection, inverter warranty, component serviceability and roof access. Savings depend on keeping the plant available for years.
