How Do Solar Panels Work?
1: The solar panels convert sunlight into DC electricity.
2: The DC electricity from the solar panels are wired through a DC-switch. The DC-switch is there for safety reasons and it can be used to turn off the flow of electricity if needed.
3: The DC electricity then goes through a solar inverter that inverts the electricity from DC electricity to AC electricity.
4: Using solar battery storage is optional. Note! Solar batteries always store DC electricity. You can decide if you want to connect the battery before the inverter so you store DC electricity directly, or if you want to connect it after the inverter, which means the battery will re-convert it from AC back to DC.
5: From the solar inverter, the AC electricity flows through an electricity meter. The electricity meter measures solar electricity production, solar electricity consumption, amount of electricity bought from the grid, and amount of electricity sold to the grid.
6: From the electricity meter, the AC electricity goes to the fuse box where it is fed into the household's electricity system.
7: Solar electricity can then be used within the household, for example to power lights and appliances.
