In most residential solar designs, the electricity produced by solar PV systems can be used to feed into the electricity network (the grid) or get used within the home or building. When the solar system is able to feed back into the grid the design is called on-grid.
1. Solar panels convert sunlight into DC power
2. The inverter converts DC power to 240volt AC power for households
3. When solar production exceeds home consumption the meter measures your export and your account will receive a credit*
4. Any surplus electricity simply flows back into the mains grid for use elsewhere
