Drop your electricity bill to zero.
With the PM Surya Ghar subsidy and grid net-metering, solar is no longer an expense — it is an investment that pays for itself in under 3 years.
Net Metering
Sell excess power back to the grid.
During the daytime, your solar panels generate more electricity than your home consumes. This excess power is exported to the government grid through a bidirectional net meter.
At night, you import power from the grid. At the end of the month, your DISCOM billing software subtracts the exported units from your imports, cutting your bill down to zero or giving you a credit balance!
The Subsidy Benefit
*Subsidy is credited directly to the beneficiary's bank account within 30 days of installation via the National Portal for Rooftop Solar.
