The individual solar systems are of 2 types. On-grid and Off-grid. On-grid means that the solar system that you install at your home, will be connected to the grid. There you will get the facility of net metering. Meaning, during the day, the electricity produced by your solar panels, will first power you house, and if there is any surplus, it will be transmitted to the grid. So that it could be used by others. And at night, when the solar panels do not produce electricity, You use the electricity from the grid.
You will have to pay for the electricity that you use from the grid, and you will get paid for the electricity that you transmitted to the grid. The net of the two will be your electricity bill. This is known as net metering.
