5KVA Grid-Tie Home Solar Runs 3 ACs, 2 Fridges, 2 TVs — Bill Down by 90%

Narrated by Mr. Raju, Su-Kam's authorised distributor in Maharashtra, this was a heavy household — three air-conditioners, two refrigerators, two televisions and more — with a monthly electricity bill north of ₹5,000. A 5KVA Su-Kam grid-tie solar system brought it down by roughly 90%.

The key was grid-tie with net metering: solar runs the home through the day, and any surplus is exported to the grid for credit, so the meter effectively runs backward when the sun is strong. The family kept every appliance running while the bill shrank to a fraction.

Grid-tie made sense here precisely because the home still had grid access — no batteries required, just panels, a grid-tie inverter and a net meter. It is the lowest-cost route to big savings for urban homes, and Su-Kam was among the early Indian brands pushing it to residential customers.

For Kunwer Sachdev, stories like Mr. Raju's were the point: solar that pays for itself for an ordinary family, not a science project.
