The parts of a solar park
- Solar panels generate direct current (DC).
- In order to achieve higher voltages and to reduce losses, panels are wired via so-called strings in series connection.
- In larger systems, there could also be a parallel connection for which special combiner boxes are used, sometimes with monitoring equipment.
- The inverter will transform the DC into grid-compatible alternating current (AC). For larger systems a transformer may be necessary between the inverter and the public grid.
