The netting of generated-consumed power (known by the term net-metering) is one of the promotional tools for self-production and self-consumption with renewable energy and applied in different countries, particularly for photovoltaic installations. The net-metering allows the consumer to cover a significant part of own consumption, while giving the opportunity to use the power grid for indirect storage of green energy.
The term “net” is apparent from the fact that consumer debit / credit refers to the difference between the energy produced and consumed in a given period. This period is usually the current cycle of counting and invoicing of the consumed energy. If there is excess energy, this usually is not lost for the consumer but is credited accounting for a certain period of time (usually a year) and so the final settlement is done.
The development of photovoltaic systems by autoproducers concerns the installation of fixed photovoltaic systems to cover own needs of electricity, by applying energy netting. As energy netting is meant the netting of produced power by the photovoltaic system with the consumed energy at the autoproducer facilities, that carried out on an annual basis. In the energy netting the produced energy is not essential to synchronized with the consumed energy.
These photovoltaic systems can be installed on buildings or on ground, or in other structures, including those in the primary sector (barns, farms, etc.) according to the current planning legislation. The systems are installed in the same room with the consumption facilities that supply or in a neighboring area.
The ARS Construction SA with five years experience in small and large scale energy projects, takes full licensing, design, supply and installation of your PV system, always according to your needs. Contact us to inform you about the licensing process and to receive our offer.
Basic terms and conditions for self-production photovoltaic systems installation with energy netting
- The existence of active permanent power in the name of autoproducer through which powered the installation of its consumption.
- The photovoltaic system is assigned exclusively to a consumption counter, the installation consumption counter which feeds.
- The photovoltaic system is installed on the same or adjacent area to the consumption installation to which is assigned (The netting is not permissible with consumption of the same natural or legal persons in other locations).
- The interested party has the legitimate use of the system installation space.
- The interested party has fully repay their electricity accounts of his Supplier (or is included in debt adjustment scheme).

Basic parameters for dimensioning a photovoltaic system with self-production energy netting
Is there a limit to the number of self-production systems that can be installed?
Where to submit the connection request and what should be attached?
For this stage With the application documents you submit together the data mentioned in the application form (templates are available on the website of HENDO, www.deddie.gr).
The connection request is received and protocols only if the data of the application and the documents submitted with the declaration are fully and correctly completed. Precondition is that a relevant technical study should be undertaken from an appropriate specialist engineer and the type of equipment to be installed should have been selected.[/mk_custom_list]
When the connection of photovoltaic self-production system is activated?
- The request by the person concerned in which the readiness of the installation, will be indicated attached with the No. 11-14 documents form the connection request (relevant template is available on the website DEDDHE)
- The completion of the work required on the part of HENDO, is to replace the existing counter, the construction of any connection project and the carrying out of necessary checks to the production site for the secure connection to the network.
