The name of the system itself comes from the way it operates, namely – in parallel with the grid. It consists of solar PV panels, an inverter (one or several) and a switchboard. It contains no batteries. The power capacity of these systems can range from 250Wp to infinity, depending on customer needs.
The size of an on-grid system is determined mainly by two factors: the area which the customer has available for construction and the investment they are willing to make.
It is important that the location of the plot or building has southern exposure to the sun and does not to have any overshadowing from trees, buildings etc. at any given time during the day.
On-grid systems can operate under two main scenarios: entirely for the sale of the electricity produced or for own consumption.
