Net metering in rooftop PV is the new energy step to eliminate electricity costs for households and businesses.

Energy offsetting (net metering) in rooftop PV is the new energy step to eliminate electricity costs for households and businesses.

Net metering is a billing mechanism that credits PV owners for the electricity they add to the grid. For example, if a residential customer has a PV system on the roof of their home, it may produce more energy than they use during the day. Net metering, in other words, allows residential and commercial customers who generate their own electricity to resell the electricity they do not use to the grid. In each metering cycle, the energy generated by photovoltaics is offset against the energy consumed, resulting in an economic benefit to the producer from the energy savings, as well as the resulting benefits to the environment and society. The higher the price of electricity, the greater the benefit for the producer.

In practice, the consumer ends up paying for the energy consumed minus the energy produced. For example, if a house consumed 900Kw of electricity and its PV installation produced 700Kw then on a net basis it will only be charged 200Kw (900Kw - 700KW = 200KW).

If, on an annual basis, we produce more energy than we consume, then the difference is credited to our account. Otherwise, the consumer is only charged for the energy consumed, after the energy produced by the RES system has been deducted. Net metering creates cumulative economic benefits in terms of employment, income and investment as it increases demand for solar energy systems, which in turn creates jobs for installers, electricians and manufacturers working in the solar supply chain sector. The renewable energy sector is strengthened without any financial burden on the Electricity Market Operator LAGIE... As is well known, the price of electricity is volatile, which is detrimental to the final consumer. The implementation of net metering makes this market fairer, since the consumer, by producing the energy he needs himself, dramatically reduces his exposure to electricity price increases.

The increase in the selling price of electricity is no longer an enemy, but an ally. The higher the price per kWh, the faster the year of payback of the capital invested in an energy system comes.

For example, a house (100sqm) with a consumption of 5,000kWh and a heat pump with a consumption of 3,000kWh (per year) would pay 1,900€ to the PPC. In contrast, with a 5kWp photovoltaic net metering would annihilate the electricity costs. Payback 4 years! Return of 25%!

Some advantages offered by renewable energy sources (photovoltaic, biomass, etc.)....... They enable everyone to produce environmentally friendly energy and at the same time earn an extra monthly income from its sale. With the income from the sale of the energy, they make payback on the investment in a short period of time while not needing complex procedures.
