A grid interactive solar system feeds the energy directly into the public grid and the surplus energy is consumed by local loads. A solar grid inverter adapts its voltage and frequency to the grid voltage and frequency. A solar grid inverter can be best understood as a supplier of electrical current to the grid and to grid-connected loads.
Compensation for the exported electrical energy may be given by the utility in the form of net-metering or a feed-in tariff mechanism.
In comparison with stand-alone systems:
- All available solar energy is consumed or exported
- No battery bank required
- Solar grid inverter capacity need not match the connected load
- Higher system efficiency
- Fewer system components
- The system doesn’t work during grid outage
- No energy storage
