18 The grid is the network of cables by which electricity is transported from power stations to houses, buildings & other places. A grid connected PV system is linked to this grid or electrical network. This means that it can deliver the electricity it produces into the electricity network and therefore no battery or other storage is needed. On-grid PV Systems
