The subject of part 1 is the construction of a photovoltaic installation at the Company's Headquarters. The minimum power of the installation is 38.25kWp, while the maximum should not exceed 38.95kWp.

The panels were placed on the CCARPORT CPE structure with a slope of about 10o above parking spaces, on one structural slope not related to the ground from the south. The power of the installation is 38 880 Wp, the installation consists of 72 panels with a capacity of 540 Wp each bifacial. They are connected in 4 Strings (two Thongs of 18 panels connected to the MPPT-1; and two Thongs with 18 panels connected to the MPPT-2 inverter. The energy from the installation will be used for the needs of the Investor. The surplus energy will be blocked by ARPC CONTROL and will not be transmitted to the network of the operator PGE DYSTRYBUCJA branch in Łódź.

DC cabling was carried out in UV conduits under the panels and fixed on the CARPORT CPE structure, the SOFAR 36KTL-X3 inverter will be mounted under the CARPORT CPE structure from the RG-NN switchgear room side and the NEO IP-54 2 x 12 surface mode with DC, AC and inverter protection will be installed. Then the wiring will be brought on top of the structure in the UV-resistant casing pipe to the ground and routed in the casing pipe in the ground to the RG-NN switchgear room where the main connection of the network operator is located. The AC cable route is routed in the ground in the DVK-50 casing pipe at a depth of about 0.7 m and introduced into the building through the existing cable channel located in the RG-LN room in the floor. In the cable route, the OPTO 40 pipe should be laid to route the Cat gel-filled twisted pair. 6e. The LGY 1x16mm grounding wire for grounding the panel structure, inverter, DC and AC protectors on the CARPORT CPE structure was connected to the earthing in RG-NN. The CARPORT CPE parking space structure is located away from the main building of PGKiM sp. z o.o. at a distance of 9.3 m, which allows the installation of DC modules without optimizers reducing the operating voltage in the event of AC voltage failure to a safe value of 24V DC.

DC voltage of up to 800V will occur only on the roof of the CCARPORT CPE parking structure to the inverter, which in no way poses a threat when extinguishing the office and social building of PGKiM sp. z o.o. The return to the previous state of PV energy production will take place by applying AC voltage 230V to the inverter.

The CARPORT CPE structure should be made in accordance with the manufacturer's guidelines, and in accordance with the assembly instructions provided with the CAPORT CPE construction and the instructions for mounting photovoltaic panels to the assembled CAPORT CPE structure. Failure to follow the manufacturer's guidelines may result in damage to the structure or panels during the use of the photovoltaic installation.

The CAPORT CPE structure not permanently connected with the ground should be placed on the ground in accordance with the specification provided by the manufacturer of the structure.

Regarding the carport construction, the structure should be designed in such a way that with a length of 26 m, 10 parking spaces are created, each with a width of about 360-267 cm. Specifically, this applies to the spacing or increase in the number of supports of the structure for the panels.
