The project envisages the construction of new photovoltaic installations on 13 technical buildings owned by the Company located in M. Lublin. The power of individual installations will not exceed 50 kWp. System voltage — 1000 V DC. Details of the panels: not less than 380Wp, polycrystalline, IP67. Photovoltaic panels will be placed on the roofs of 12 buildings on a special non-invasive structure, enabling the entire chains to be positioned in the most optimal directions, at an angle of 10 to 15 degrees and loaded with ballasts. On one building, the panels will be mounted on a special structure directly to the roof at an angle of 20 degrees. The inverter will be connected to an internal LAN with Internet access, which will allow for generating reports and live previews. In the case of long chains of PV panels, one traker tracking the maximum power point, allowing to increase yields even when some modules are partially darkened or soiled will be connected to two panels, and in the case of short chains, one tracker will be connected to one panel. All PV installations will be equipped with three-phase, transformer-free inverters, with properly selected power. In order to ensure safety, a fire switch will be installed to cut off the power supply throughout the building. In addition, the system provides in the event of an emergency power off in the facility to automatically reduce the voltage on the DC side to the level of so-called safe for DC voltage. Protection against the weather conditions of the panels will be provided by laminated glass plate coated with anti-reflective layer, lightning protection installation and equalisation connections. Cooling will be carried out in a natural way, through the circulation of atmospheric air. The absence of a cooling system is the lack of noise during the operation of the photovoltaic system. The photovoltaic modules planned for use will be made of materials that are fully disposed of. (English) | |||||||||||||||

Projekt przewiduje wykonanie nowych instalacji fotowoltaicznych na 13 budynkach technicznych, będących własnością Spółki rozlokowanych na terenie M. Lublin. Moc poszczególnych instalacji nie przekroczy 50 kWp. Napięcie systemowe - 1000 V DC. Dane paneli: nie mniejsza niż 380Wp, polikrystaliczne, IP67. Panele fotowoltaiczne będą umieszczone na dachach 12 budynków na specjalnej bezinwazyjnej konstrukcji, umożliwiającej ustawienie całych łańcuchów w kierunkach najbardziej optymalnych, pod kątem od 10 do 15 st. i obciążonej balastami. Na jednym budynku panele zostaną zamontowane na specjalnej konstrukcji bezpośrednio do dachu pod kątem 20 st. Falownik zostanie podłączony do wewnętrznej sieci LAN z dostępem do Internetu, co pozwoli generowanie raportów i podglądu na żywo. W przypadku długich łańcuchów paneli PV jeden traker śledzący punkt mocy maksymalnej, pozwalający na zwiększenie uzysków nawet podczas , gdy część modułów ulegnie częściowemu zaciemnieniu lub zabrudzeniu będzie podłączony do dwóch paneli, zaś w przypadku łańcuchów krótkich jeden traker śledzący będzie podłączony do jednego panelu. Wszystkie instalacje PV będą wyposażone w falowniki trójfazowe, beztransformatorowe, o odpowiednio dobranej mocy. W celu zapewnienia bezpieczeństwa zostanie zainstalowany wyłącznik ppoż., umożliwiający odcięcie zasilania w całym budynku. Ponadto system zapewnia w przypadku awaryjnego wyłączenia zasilania w obiekcie na automatyczne obniżenie napięcia po stronie DC do poziomu tzw. bezpiecznego dla napięcia stałego. Ochronę przed warunkami atmosferycznymi paneli zapewniać będzie laminowana szklana płyta pokryta warstwą antyrefleksyjną, instalacja odgromowa i połączenia wyrównawcze. Chłodzenie odbywać się będzie w sposób naturalny, przez obieg powietrza atmosferycznego. Brak systemu chłodzenia to brak wytwarzania hałasu w czasie eksploatacji instalacji fotowoltaicznej. Planowane do zastosowania moduły fotowoltaiczne zbudowane będą z materiałów w całości podlegających utylizacji. (Polish)
