Your Home Becomes a Mini Power Plant
An On-Grid (also called Grid-Tied) solar system is connected to your electricity utility's power grid. During the day, your solar panels generate DC electricity, which the inverter converts to AC and powers your home appliances first.
Any excess electricity is automatically exported to the grid. Your electricity meter records this export, and the DISCOM credits you for every unit sent back — this is called Net Metering. At the end of the month, you only pay for the net units consumed (imports minus exports).
When the grid is down, the system automatically shuts off (grid safety requirement). For backup power, consider a Hybrid System instead.

How Net Metering Works
6 AM – 10 AM
Sunrise — Panels Begin Generating
Solar panels start generating electricity as the sun rises. Your home appliances run on free solar power.
10 AM – 4 PM
Peak Generation — Export to Grid
At peak sun hours, your panels produce more than you consume. Excess power flows to the grid — your meter runs backwards!
6 PM – 10 PM
Evening — Draw from Grid Using Credits
After sunset, you draw power from the grid as usual. But your exported units offset this — reducing or eliminating your bill.
Month End
Billing — Net Units × Tariff = Your Bill
DISCOM calculates: Units Imported − Units Exported = Net Units. You pay only for net units consumed. Excess credits carry forward!
