Special programs for households with small photovoltaic systems up to 10,8 kW offer significant benefits through energy net metering (net metering) and virtual simultaneous net metering. Let’s take a closer look at how they work and what benefits they offer:
1. How the simultaneous net metering program works:
- Households install a photovoltaic system at their home.
- The energy produced by the photovoltaic system meets their energy needs in real time.
- If the photovoltaic system produces more energy than is being consumed at that moment, the surplus energy is fed into the grid.
- Net metering is carried out in 15-minute intervals, and surplus energy is recorded and deducted from the household’s next bill.
2. Virtual simultaneous net metering:
- Under this model, the generating station can be located somewhere other than the consumption site. For example, the photovoltaic system may be located on a rural property or at another site that is not connected to the home.
- The energy produced is netted against the energy consumed by the household, even if the generating station and the home are not in the same location.
3. Special “Residential Photovoltaics” Program up to 10,8 kW:
- System Capacity: The installation of photovoltaic systems for residential use is limited to 10,8 kW per electricity supply.
- Energy Netting: This program allows for simultaneous net metering, where surplus energy produced can be credited to the electricity bill.
-
Surplus Energy: If there is surplus energy that is not used, its value is credited to the self-consumer’s ΔΕΗ bill, reducing the total cost.
4. Examples of how it works and the benefits:
-
Example 1: Residential system without virtual net metering
- Installation: A household installs a photovoltaic system with a capacity of 8 kW.
- Energy Consumption: The household consumes 7.000 kWh per year.
- Energy Production: The photovoltaic system produces 8.500 kWh per year.
- Netting: The 7.000 kWh fully cover the household’s consumption. The additional 1.500 kWh are credited to the bill, reducing the bill for the next period.
-
Example 2: Residential system with virtual net metering
- Installation: A homeowner installs a 5 kW photovoltaic system at a holiday home that they visit only in summer. The system produces energy all year round.
- Consumption: The homeowner’s primary residence, which has no photovoltaic system, consumes 4.000 kWh per year.
- Netting: Although the photovoltaic system is located at the holiday home, the energy it produces is netted against the consumption of the primary residence. The bill for the primary residence is reduced by the energy produced by the photovoltaic system at the holiday home.
5. Benefits for households:
- Lower Bills: Installing this type of system significantly reduces electricity costs, as the household produces its own energy.
- Energy Independence: Dependence on the public grid is reduced, especially during the sunnier months.
- Environmental Benefits: Households help reduce CO2 emissions and promote the use of renewable energy sources.
