What kind of adjustment is needed for a PV system installed on the current electric system?

The transit from the traditional system to the photovoltaic one does not imply big changes. The new system will be connected to an inverter, which allows the transformation from DC, generated by PV modules, into AC, normally used for house networks. The user will be using the energy produced by his/her own system during the day and the energy provided by the previous traditional system during the night or during the days in which the system’s performance could be lower.

The system will have two meters installed by the network operator: one will be incoming, in order to read the user’s energy consumptions coming from the national network; and one out-coming, to read the electric energy fed by the private PV system.
