1) Where can PV systems with self-generating energy compensation be installed?

These photovoltaic systems can be installed on buildings or on land or other structures, including those in the primary sector (barns, farms, etc.) according to the current urban planning legislation. The systems are installed in the same room with the consumption facilities that supply or in a neighboring area.

2) Who can install a PV system with self-generating energy compensation?

The right of establishment is granted to individuals (traders or not), and legal entities of public law and private law, which they either own the site in which the PV system will be installed, or have the legal use (e.g. hire, free concessions, etc.) and have ensured the written consent of the owner of the site. In case of a photovoltaic system in shared or jointly-owned building space, one or more PV systems may be installed, of which each one will be mapped to a single consumption meter. The right of establishment, in this case, is granted to the owners of the condo or those with the legal use of these after the granting of use of a shared or jointly space or part of the remaining co-owners. To connect to the provision of communal, the owners of horizontal properties are represented by the administrator. The necessary prerequisite is to have the consent of all co-landlords of the building, which should be demonstrated in a practical or a unanimous decision of the general meeting or by the written agreement of all the building's co-lanlords.

3) What are the basic terms and conditions for the installation of PV systems with self-generating energy compensation?

The main terms and conditions for the installation of PV systems with self-generating energy offsetting are as follows:

- The existence of active permanent power supply in the name of the self-producer through which its facility consumption is powered. The PV system is assigned exclusively to a consumption meter, i.e. with the installation consumption meter u954 which it feeds.
- The PV system is installed in the same or an adjacent room to the consumption installation to which it is assigned (netting is not permissible with consumptions of the same natural or legal person in other locations)
- The interested party has the legitimate use of the system installation space. The interested party has fully paid their electricity bills of their supplier (or is included in a debt restructuring scheme).

4) What are the key parameters for dimensioning a PV system with self-generating energy compensation?

For the dimensioning of the PV system it is appropriate to take account of the annual consumption of the installation where it will connect. Given that the energy compensation is carried out on an annual basis and any surplus energy after the annual offset is not compensated, the annual producible energy by the photovoltaic system will not exceed the total annual consumption. For information purposes, it is noted that the production of PV systems takes values ​​in the interval of 1200-1600 kWh / kWp / year, depending on the coordinates and orientation of the installation, with a weighted average price of approximately 1400 kWh / kWp / year. Therefore, the system power should be chosen in light of the annual energy needs, within the constraints set by the Ministerial Decision.

5) Where to submit the logon request and what is attached to it?

For consumption installations connected in the LV network, the logon request is submitted to the local unit of the HEDNO (Area) 4. Along with the application, the following is submitted: the documents with numbers 1-9 and information mentioned in the application form (form available on the website of the HEDNO). The connection request is received only if the application data, and the attached documents and records are complete and properly completed. A precondition is to have worked out the relevant technical study by the appropriate specificity engineer and to have chosen the type of equipment to be installed.

6) What procedure is followed afterwards?

The Area goes forward with the written version Connection Offer to the applicant within one (1) month of receipt of the application. The offer includes the description of projects and activities to be undertaken by the HEDNO for the connection and the total related expenditure, as well as the works and actions the person interested has to  do to make the connection. The offer is valid for a period of three (3) months from the date of its adoption. Especially for the non-interconnected islands, the Connection Offer will be issued if there is any PV power available margin in the specific electrical system.

7) When is a Connection Agreement for the PV system with self-generating energy compensation signed?

The person interested, within the three months of the offer, applies for the signing of the Association Agreement (form available on the website of the HEDNO) to the region, and provides the additional documentation required (item 10 of the application form). The District shall notify the complainant of the procedure for payment of the connection costs and the signing of the Association Agreement. Any idle lapse of the three month period (without contract signature and payment of the costs incurred) implies the compulsory termination of the connection offer.

8) How much does the connection of the PV system with the LV Network cost?

For a PV power system up to 55 kWp, the connection will cost 300 €, where the replacement of existing consumption meter is required, otherwise the connection will cost 370 €, in the case of single-phase supplies or 390 € in the case of three-phase supplies. For a PV system power exceeding 55 kWp and up to 100 kWp, the connection will cost 450 €. The above costs include the cost of control of the production meter and the tension transformers, where required. These costs apply provided that no network works are required to connect.

9) When is the offset agreement for the PV system with self-generating energy compensation signed?

After signing the Connection Agreement an application by the self-producer to the supplier of electricity is submitted, with whom he has a supply contract as a consumer to sign a netting agreement. The process is completed within 15 days from the date of receipt of the request. The Netting Agreement goes into force on the date of activation of the connection of the PV system.

10) What is the duration of the offset agreement of the  self-production PV system?

The Offset Agreement signed between the Supplier and the self- producer is valid for 25 years with effect from the date of activation of the connection of the PV system. In the case of change of the supplier after the activation of the PV system, the offset contract with the previous supplier shall automatically lapse and new Offset Agreement will be concluded between the self-producer and the new Supplier for the remainder of the 25-year period. Also, a new contract for the remaining period is concluded in case of change of the account user consumption facility. The same applies in the case of transition of a functioning PV system that was installed as part of the Special Program for the Development of Photovoltaic Systems in buildings (Official Government Gazette B’ 1079/2009) to the scheme for self-production with

energy offsetting.

11) When is the connection of  the PV self-generating system activated?

To enable the connection of the PV system, the following is required:

The request from the party concerned, stating the readiness of the installation with the attached documents with numbers 11 to 14 of the connection application form (model available on the website of the HEDNO).

The completion of the works required in terms of the HEDNO as replacing of the existing meter, any connection construction project and the performing of the required checks of the production facility for secure connection to the network.  

12) Are changes in the equipment of the self-generating PV system accepted?

What is accepted is the change of the type or manufacturer of the modules and inverters, by written notification to the competent District with the attachment of the corresponding technical manuals and certificates, not later than the submission of the application of the connection activation, without requiring the modification of the Connection and Offset Agreement, provided that the new design of the equipment does not vary the total installed capacity (kWp) of the system beyond 3% of the initially declared and the power limits regarding the size allowed referred to in Question 2 are respected.

13) Are Applications of self-generating PV systems power augmentation accepted?

Applications of power augmentation on non operating systems with a Connection Offer, entail cancellation of the Offer and a new Offer according to what is in force. Exceptions are valid for the areas for which there is a limited margin of power for which the power increase will be considered a new claim. The power augmentation of the P / V self-generating system following the connection activation will be possible at the same voltage level after the new request, the new Connection Offer and the payment of the relevant expenditure. In these cases an amendment of the Connection and Offset Agreement will follow regarding the power of the self-generating system.

14) Is the transition from the "Special Program of development of photovoltaic systems in buildings" in the status of self-generating with energy compensation allowed?

The transition of operating systems installed under the "Special Roof Program 'in the scheme for self-production of energy offsetting is permissible for the remaining period of 25 years against the originally concluded netting agreement. For the transition, the submission of such a request, the conclusion of a new Connection Agreement and the conclusion of a new Offset Contract with the Supplier are required. The applicant is charged with the transition costs.

15) Are systems of the “Special Roof Program” allowed to coexist in the same space with u945 auto production systems with energy clearing, with reference to the same consumption meter?

No, the coexistence of systems with reference to the same consumption meter, i.e. with reference to the same number of providers is not allowed.

16) Is the installation of a PV system with reference / assignment to more consumption meters allowed?

No, each PV system is assigned exclusively to a consumption meter, i.e. with a supply number.

17) Is there a limit to the number of self-generating systems that can be installed by the same natural or legal person?

There is no limit, provided that the PV systems can be assigned to different consumer installations, i.e. different numbers of supply and consumption meters.

18) In case of usufruct, bare ownership or joint ownership in a property, who can install a photovoltaic self-generating system?

If the supply is the name of the person entitled to usufruct, the latter without the consent of person entitled to bare ownership. If it is in the name person entitled to bare ownership, the latter with the consent of the person entitled to usufruct. In the cases of joint ownership, the person in whose name the supply is granted, with the written agreement of the joint owners.
