Net Metering

Netting of produced-consumed energy (known as net-metering) is one of the tools for promoting self-production and self-consumption with RES and is applied in various countries, mainly for photovoltaic installations.

What is Net Metering?

With the term Net Metering or otherwise “Energy Offsetting” we refer to the self-production of energy through the use of interconnected Photovoltaics, with the public grid.

The energy produced by the Photovoltaics is subjected to an energy offset which is subtracted from the energy consumed thus covering the energy needs of the consumer.

How does Net Metering work?

The solar radiation that falls on the mirrors is converted into alternating voltage using an (inverter) converter, which channels it into the network and at the same time, if there are energy needs, they are met directly by the Photovoltaic Net Metering.

In the installed Photovoltaic system, two meters are placed (or a dual flow meter) in order to measure the energy produced by the Photovoltaic and that which enters from the PPC network.

Finally, the meter calculates the difference between produced and consumed energy and if there is excess production energy, it is credited to the next settlement account.

Energy Offset Benefits

The numerous benefits of Energy Offsetting are well known as the rate of growth of Photovoltaic installations and the preference of private individuals for the application of Net Metering is now exponential.


More specifically:

  • The surplus energy produced by the Photovoltaic is not lost with the energy offset, but is credited for future use
  • A low and stable electricity price is ensured for a period of 25 years regardless of PPC increases
  • It is a profitable investment in just 5 years
  • The installation of Photovoltaics is done easily on a roof, roof, ground or other constructions without the visual effect being unsightly
  • Net Metering offers independence from conventional forms of energy
  • Ecological awareness is cultivated as a “clean” and renewable source of energy is used to meet the needs of a facility, reducing the energy footprint on the planet
  • Finally, you become your own producer as you consume the energy you produce on the roof of your house
