Types of Solar Power Plant:
1. On Grid: On-Grid system is solar PV system that only generate power when the utility power grid is available to function. If it is producing more power than is being consumed, the surplus is fed into the mains power grid to Govt. which will be credited in your next electricity bill or pay you for the same through Net Metering System by Indian Govt.
2. Off Grid: An Off-Grid system is completely disconnected from the traditional electric power grid. Without a connection to the utility grid, batteries are essential to balance periods of excess production and excess demand. To protect against shortfalls of power when the solar system is under-producing and the batteries are discharged.
3. Hybrid: A Hybrid system is also connected to the traditional utility power grid and adds battery-backup to the system. Solar electric system production depends on the available sunlight. When production exceeds demand, the excess power can charge the batteries, which store the electricity. When the system is producing less electricity than demanded by the home, the batteries can make up the shortfall.
