Scenario 1 — No Battery (Export Model)
Daytime:
15 kWh exported
Credit = 15 × 10 = Rs 150
Night:
15 kWh imported
Cost = 15 × 45 = Rs 675
Daily net gap = Rs 525
Annual leakage:
Rs 525 × 365 ≈ Rs 191,625
Under net metering, this leakage did not exist.
Under net billing, it is structural.
Scenario 2 — With SES 16.07kWh Battery
Daytime:
15 kWh stored
Night:
12.8–14 kWh supplied by battery
Grid import minimal.
Daily retail cost avoided:
~Rs 600–650
Annual savings:
Rs 220,000–240,000 (depending on load profile)
