As long as your 2 kW solar system is connected to the grid, or say that you have a grid-coonected rooftop solar system, you will continue to receive monthly electricity bills from your state’s DISCOM. However, the amount to be paid against your bill will drastically be reduced, even to Rs 0. During those months, when you don’t draw any electricity from this grid and contribute solar electricity to it instead, your bill will reflect a positive solar credit balance which can be adjusted in monthly billing cycle.
