1. 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 applied in various countries, mainly for photovoltaic installations. Net-metering allows the consumer to cover a significant part of his own consumption, while at the same time it enables him to use the network for indirect storage green energy.
The term "net" results from the fact that the consumer's debit/credit refers to difference between consumed and produced energy in a certain period of time. This period is usually its respective counting and billing cycle of consumed energy. If there is an excess of energy, it is usually not wasted but credited for a certain period of time (usually one year), at the point that the final liquidation takes place.
The net metering program really has many benefits. Below are the highlights:
- Ensuring a fixed price of the electricity produced for 25 years, regardless of the current or future consumption price.
- Annual return on capital equal to at least 16% and usually around 20%, with prices quite attractive compared to current bank interest rates.
- Short investment payback time (around 5-6 years).
- Reduction of the total value of electricity from 65% to 100%.
- Increase in Property Value with a parallel increase in the energy category, due to energy production from Renewable Energy Sources.
- Exemption of the self-producer from any taxation of his income from the electricity he produces.
- Zero dependence on the state to subsidize and pay for the investment, since the settlement takes place every 4 months by the electricity provider.
Domestic energy production is done using photovoltaics placed on the roof of the building. The energy produced by the PV panels is used for the energy needs of the house and the energy that is not used is attributed to the DEDDIE network.

2. Off-Grid PV systems

Autonomous photovoltaics (off-grid) are electricity supply systems with the help of solar energy. They differ from On-Grid photovoltaic (or grid-tied) systems in that no interconnection with the public grid (e.g. PPC) is required to operate. Autonomous systems, in addition to solar energy, can also exploit wind energy, in which case they are called autonomous hybrid systems.

Αutonomous systems include batteries (accumulators). In these systems during the absence of energy from the sun or any other form of energy, the load is supplied through the accumulators. Usually, autonomous power supply systems are used in buildings that are remote and therefore costly or impossible to connect to the public network, in floating boats, holiday homes, caravans, etc.

3. Smart Solutions

More and more people are upgrading their lifestyle and quality of life by implementing "smart solutions" in their daily life, which offer significant energy savings and, by extension, money savings, while at the same time being environmentally friendly. Indicative examples: installation of energy saving products (Led lamps etc.), heat pumps, use of electric propulsion and of course the combined approach of renewable energy sources with the purchase of high energy class devices.
