Bill = (import − export) × tariff + fixed charges

On-grid: the simplest and cheapest

Panels make DC power; the inverter turns it into AC for your home. Whatever the home does not use goes to MSEDCL through the net meter; at night the home takes power from the grid. In a power cut the on-grid inverter switches off on purpose, so that no power goes into the line while the lineman repairs it; there is no backup. Best for: most homes on PM Surya Ghar, with the full subsidy.

Hybrid: solar plus a battery

Same as on-grid, plus a battery. By day solar runs the home and charges the battery; extra still goes to the grid. In the evening and in a power cut the battery runs the home (lights, fans, TV, fridge, within the inverter’s backup load). Costs more than on-grid because of the battery. Best for: areas with frequent power cuts, shops, clinics, work from home.

Net meter: how your bill is worked out

MSEDCL replaces your old meter with a two-way (net) meter. It counts units you take from the grid (import) and units your solar sends to the grid (export) separately. Your bill is import minus export, times the tariff, plus fixed charges. If you send more than you take, the extra units are carried forward to the next bills and the balance is settled once a year as per MSEDCL / MERC rules. We apply for the net meter for you.
