Mr. Rajan's family of six was consuming around 800+ units bi-monthly, landing firmly in TANGEDCO's highest slab. With a 5 kWp system generating 825 units/month, their grid draw dropped to under 50 units — saving them over ₹46,000 annually.

A family of three with an AC and refrigerator running most of the day. At 580 units bi-monthly, they were in the high-usage TANGEDCO slab. After installing a 3 kWp system, their grid import dropped below 90 units bi-monthly — crossing back into the free slab.

Mr. Selvam's tile-roofed house had limited area but consistent usage around 300 units bi-monthly. A 2 kWp system at 75% efficiency (sheet roof) generates around 330 units/month — enough to nearly zero out the grid bill most months.

Mr. Anand's Chennai home runs two ACs through the night. At 700 units bi-monthly he was deep in the high-usage TANGEDCO table. A 4 kWp system exports surplus units during the day and earns ₹3.61/unit credit, effectively covering his night consumption.
