A photovoltaic system usually consists of 3 PV components (without storage/batteries):
The photovoltaic packages always include the solar modules and the appropriate inverter(s). In the case of entire solar parks, the entire installation material with cables, plugs and fences is usually also offered.
PV components of the highest quality are combined, which are technically optimally matched to each other.
The great advantage of PV packages is that they are always offered at a lower price than the sum of the prices for the individual components.
