Solar PV panels receive solar radiation and turn the sunlight into DC power, Solar inverters convert the DC Power into AC power. AC power can be used by the end user and the remaining energy will distributed to the grid.
When the solar systems are not producing power, for example at night, your power is supplied by the Grid as usual.
Though the solar power system is connected to the grid, the consumer has to pay only for the surplus electricity he consumes. The bill generated on a monthly basis determines whether the consumer has any payments to be made. However, at the same time if the consumer utilizes less electricity, the excess is fed back in the grid.
