Net-Metering or otherwise the self-generation of electricity now allows the Greek consumer to generate the electricity he needs at home or in his professional activity. Simply put, each of us can now install a photovoltaic system in our home in order to produce our own clean and free electricity from the sun for our own use. Consequently, the consumer also becomes a producer of electricity so that he can meet his own needs.
The innovation that self-production brings to the building sector could only be compared to the proliferation of solar water heaters for free hot water. Only this is an even more important development, since it is now possible to cover all the energy needs of a building (electricity, heating) from the sun, not only hot water
How it works:
The principle of operation of a Net-Metering PV system does not differ from the PV systems that have been installed in buildings in recent years. Photovoltaic panels absorb solar energy and convert it into electricity. The electricity generated by an inverter is then converted into an usable form. In other words, it becomes 220V AC, as is the current offered by the PPC network. This current through a meter exits the low voltage network of PPC. The reading of this meter is offset by the reading of the consumption meter and the resulting difference is either charged or transferred to the next bill.
