Photovoltaic

 

Envisol is active in the field of Renewable Energy, in particular in the photovoltaic sector. With credibility, method and with the help of our experience in the production of public works, we undertake to support you and ensure the best result in all stages of the project from the initial idea to its completion and proper operation.

For the installation of systems up to 500 kWp the steps required are

1. the Environmental Compliance exemption certificate granted by the Region,
2.  approval by Urban Planning,
3. the offer of terms of connection by the Public Power Distribution Network Administrator and
4. Signing of the contract for the purchase and sale with the Renewable Energy Sources Operator and Guarantees of Origin, formerly of LAGIE.

For systems ranging from 500 to 1000 kWp (1 MWp), the steps required are

1. Environmental Permit granted by the Region (excluded projects within certain industrial activity receptors),
2. approval by the Urban planning,
3. Offering of terms of connection by the Public Power Distribution Network Administrator and the
4. Signing of the contract for the purchase and sale with the Renewable Energy Sources Operator and Guarantees of Origin, formerly of LAGIE.

For systems with a power of more than 1000 kWp (1 MWp), the steps required are

1. the issue of a production license by RAE and then
2. an installation permit by the Region (which also requires the approval of Environmental Protection Terms where this is required),
3. approval by Urban Planning,
4. terms of connection from the Public Power Distribution Network Administrator and the
5. Signing of the contract for the purchase and sale with the Renewable Energy Sources Operator and Guarantees of Origin, formerly of LAGIE.
6. Finally is required the issuance of a license of operation by the Region.

The new institutional framework (L.4414/2016, GG 149A / 9.8.2016) incorporates the "Environmental and Energy State Aid Guidelines (2014-2020)" (2014 / C 200/01) of the European Commission. The following cumulative conditions shall apply from 1 January 2016 to all new aid schemes and schemes:

• The aid is granted as a surcharge, in addition to the market price at which producers sell electricity directly to the market.
• Beneficiaries participate in market mechanisms, i.e. they are subject to standard balancing powers, unless there are no competitive intraday markets.

Under the new aid scheme, in the case of photovoltaic, the following are now applicable:

• For projects with up to 500 kWp, the feed-in-tariffs support mechanism can be applied.
• For projects with a power of more than 500 kWp, the aid is granted as a differential increment, in addition to the market price at which producers sell electricity directly to the market, namely the feed-in-premium mechanism. In addition, aid for projects of this scale will be granted in the context of a competitive process.

Self-production with net metering

Energy net metering is applied across the country as follows:

1. 
   In the interconnected system (mainland and interconnected with it, islands)
2. 
   a) The power of each photovoltaic system may be up to 20 kWp or up to 50% of the agreed power consumption of the installation (in kVA), if the latter exceeds 20 kWp.
3. b) Especially, for legal entities governed by public or private law, pursuing public service purposes, general or local, the capacity of each photovoltaic system may be up to 100% of the agreed power consumption.
4. c) In any case, the maximum power of a photovoltaic system to be installed may not exceed 1 MWp.
5. 
   Non-Interconnected Islands (NII)
6. 
   a) In non-interconnected islands, the capacity of photovoltaic systems may be up to 10 kWp and especially in Crete 20 kWp or up to 50% of the agreed power consumption of the installation (in kVA), if the latter exceeds 10 kWp or Crete the 20 kWp.

(b) Especially for legal entities governed by public or private law, pursuing public or other general interest purposes, general or local, the capacity of each photovoltaic system may be up to 100% of the agreed power consumption.

(c) The maximum power of a photovoltaic system to be installed in non-interconnected islands may not exceed 50 kWp for Crete and 20 kWp for other non-interconnected islands.

The exception is the installation of photovoltaic stations by public or private legal entities pursuing public or other public interest purposes, whether general or local, in non-interconnected islands except Crete, where the power cannot exceed the maximum of 100 KWp, and especially for Crete, cannot exceed the maximum of 300 kWp.
In general, permissible installations refer to fixed landing systems installed on land, on buildings or other structures (including those in the primary sector), and in the case of photovoltaic plants installed on land, the use of tracking systems is permitted.

The right of establishment includes persons (tradesmen or not) and legal entities governed by public and private law which either own the site in which the photovoltaic system is installed or lawfully use it (for example, by leasing, free of charge concessions, etc.) and have secured the written consent of the site owner. The systems are installed in the same place as the installations that feed or adjacent to it.

The basic terms and conditions for the installation of self-producing photovoltaic systems with energy net metering are as follows:

• The existence of an active permanent power supply in the name of the auto producer through which it is supplied his plant.

• The photovoltaic system is solely associated with a consumption meter, that is, the meter of the power plant it feeds (not applicable to virtual energy net metering).

• The photovoltaic system is installed in the same or adjacent space as the installation of consumption to which it is assigned (it is not allowed to offset consumption of the same natural or legal person in other locations except for the categories of self-producers for which virtual energy net metering is applied).

• The person or legal entity concerned has the legitimate use of the site

• The person or legal entity concerned has fully paid out the electricity bills of the Supplier concerned (or has entered a debt settlement regime).

The Net metering Agreement signed between the Supplier and the Auto producer has a validity of 25 years, with effect from the date of activation of the connection of the photovoltaic system. If the auto producer changes a supplier to electrify its consumption, the Agreement is automatically terminated and a new Net Metering Agreement is concluded for the remaining twenty-five (25) years between the auto producer and the new supplier.

For the designing of the photovoltaic system it is advisable to take into account the annual consumption of the plant to which it will be connected. Since the energy offset is carried out on a three-year basis and any surplus energy after three-year netting is not compensated, the annual energy produced by the photovoltaic system should not exceed the total annual consumption.

 

Virtual net metering

Especially for self-producers who are legal entities governed by public or private law pursuing public interest or other public interest purposes of general or local scope, for agricultural facilities and for energy communities, photovoltaic stations may be installed to meet their own needs by applying virtual energy netting.

Virtual metering is to offset the electricity generated from an auto producer's RES station with the total electricity consumed in an auto producer's plant, of which at least one is either not in the same or adjacent space as the RES station or where it is located , is powered by a different supply.

Types of Support for Photovoltaic Panels

 There are two main types of support for photovoltaic panels:

• • The fixed bases, in which the panels remain in one direction and the ones
• • Trackers, in which the panels follow the path of the sun.

Where photovoltaic facilities exceed 2.5 m above ground level of the natural or artificial terrain, the support frames of the photovoltaic panels shall be certified for their resistance to extreme winding by an independent accredited organization in accordance with the Eurocode or DIN standard or other equivalent National Standard or, alternatively, a static proficiency statement by a qualified engineer, and the data shall be accompanied by the supporting documents for the small-scale construction work approval submitted to Urban Planning.

Installation of photovoltaic in high productivity land

For new applications for Connection Bidding after 21/9/2011 and until certain details regarding the mapping and delimitation of high productivity land are defined, the installation of photovoltaic plants on land designated as high productivity land is not allowed.

Urban planning terms for photovoltaic installation

In the design areas, photovoltaic are not allowed to be built into unstructured plots as they are constructions used for the direct or indirect servicing of buildings or their functionality and are also included in the framework of energy policy as active energy-saving systems according to Article 2 par.19 and 44 of Law 1577/1985 "On the General Building Regulation" (Government Gazette A'210), as amended and in force.
