Net-metering or "Self-Production with Energy Offsetting" is the ability to produce yourself, using RES, the electricity you consume, while at the same time remaining connected to the grid, which you use as an energy storage.
Thus, when production is greater than consumption, the surplus is "stored" in the network and used when production is insufficient. The final set-off takes place every three years and therefore the PV system should practically be designed based on your annual consumption.
How It Works
The system connects internally with your home or business with a separate meter that records the energy generated. It may include photovoltaic and / or small wind turbines. At this stage and until the installation conditions for small wind turbines are adopted, only the installation of photovoltaics is envisaged. Production is offset by consumption in each of your clearing accounts. At the end of every three years, if production is greater than consumption, excess is provided free of charge on the grid. If production is lower than consumption, you pay only the difference.
