Net-metering is called the pricing mechanism that offsets the energy produced.
Net-metering after the installation of photovoltaic roofs and related specialized electrical work is the most revolutionary step in eliminating electricity costs for households and businesses and securing extra income.
If the green energy produced, thanks to the use of photovoltaics, exceeds the needs of the household, it may be as a surplus to be stored and sold to the electricity company. Net metering credits photovoltaic owners for the electricity they add to the grid.
Thus, a home customer with a photovoltaic system on the roof of his home can produce more energy than he uses during the day, to meet his needs and to resell his surplus electricity to the electricity grid, only free electricity, but also an annual income that is not insignificant, while keeping the environment clean.
Net metering also generates cumulative economic benefits in terms of employment, income and investment, as it increases the demand for solar energy systems, creates jobs and brings benefits to the environment and society.
Today, Net-metering is one of the tools to promote self-production and self-consumption with RES and is applied in many countries in Europe and around the world.
