The PV panels will be of the Chinese company Longi and will be installed a total of 1136 pcs, all of the same nominal power of 440W and must all have exactly the same geometric dimensions. Upon delivery, or prior to this, the PV panels will be accompanied by Flash Reports indicating their "Flashed Power" as measured for each one individually (together with the unique manufacturer's number - barcode) before leaving the manufacturing plant.

The inverters will be of the Chinese manufacturer Huawei and will be three-phase, "string inverter" type, i.e. they will connect parts of the PV system directly to the grid and will have IP65 protection (waterproofing class) for outdoor installation. A total of 18 inverters will be installed. They are CE certified and comply with the following safety standards: - IEC/EN 62109-1, IEC/EN 62109-2, EN 61000-6-2, EN 61000-6-3, EN 61000-3-11, EN 61000-3-12 They also follow the following network standards: - CEI 0-21, CEI 0-16, DIN V VDE V 0126-1-1, VDE-AR-N 4105, G59/3, EN 50438 (not for all national appendices), RD 1699, RD 413, RD 661, P.O. 12.3, AS 4777, BDEW, NRS-097-2-1, MEA, PEA, IEC 61727, IEC 60068, IEC 61683, VFR-2014, IEC 62116

The installation of the PV panels will be carried out on variable inclination metallic supports of the company Profilodomi made of galvanized-hot-galvanized steel or aluminium alloy profiles, provided that they fully comply with the existing specifications and certifications.

The PV system installation site will be properly prepared to facilitate the installation of the support systems for the PV panels and other equipment according to the layout plan, which will ensure the structural adequacy of the installation and the smooth operation of the PV plant. Before any other intervention (trenching, etc.), it will be necessary to remove vegetation and level the ground over the entire area of the site (10-20 cm deep) using appropriate earthmoving equipment. In special cases of pitches that will be deemed necessary due to local conditions, additional earthworks may be carried out after a relevant study and consultation with the project supervision, such as the spreading of crushed material, internal road construction, drainage works, etc.

The fence will be made of wire mesh and will have 1 door, sliding or opening, double opening, with a total length of 5 meters. The metal posts (uprights) will be placed 2,5 m apart in slots in the ground filled with concrete.They are CE certified and comply with the following safety standards: - IEC/EN 62109-1, IEC/EN 62109-2, EN 61000-6-2, EN 61000-6-3, EN 61000-3-11, EN 61000-3-12 They also follow the following network standards: - CEI 0-21, CEI 0-16, DIN V VDE V 0126-1-1, VDE-AR-N 4105, G59/3, EN 50438 (not for all national appendices), RD 1699, RD 413, RD 661, P.O. 12.3, AS 4777, BDEW, NRS-097-2-1, MEA, PEA, IEC 61727, IEC 60068, IEC 61683, VFR-2014, IEC 62116
