Solar PV Systems

Solar PV systems are power supplies with PV modules as source. They can be “grid connected” as an additional source of electricity for feeding the electrical grid. On the other hand, they can be autonomous off-grid systems: Acting e.g. as uninterruptable power supplies (UPS) often with a battery as storage. Or, they can supply electricity to isolated houses. The power of a Solar PV system can extend over a large range from a few Watts (for small autonomous off-grid systems) up to several Gigawatts (GWp) for large grid-connected systems.
