PNI Green House 445 W monocrystalline photovoltaic panel, silver frame, 1903 × 1134 mm
Code: PNI-SRP-445WProduct detailed description
The PNI Green House 445 W is a monocrystalline photovoltaic panel in a silver frame that converts sunlight into direct current for a home or business photovoltaic power plant. With an efficiency of 22.02 % it delivers 445 W from a single module, so you do not need as many panels to build a larger array.
The panel is designed for long-term outdoor operation. It works in a temperature range from −40 to +85 °C and has IP68 protection, so neither dust nor water is a problem. It suits the roof of a family house, flat business roofs and off-grid installations that are not connected to the distribution grid.
With dimensions of 1903 × 1134 mm and a thickness of 30 mm it is a large-format module and weighs 24.2 kg. When positioning it, therefore, allow for a sufficiently sturdy structure and two people for handling.
Connection and installation
The panel's electrical values at the maximum power point are 31.88 V and 13.49 A, the open-circuit voltage is 38.49 V and the short-circuit current is 14.23 A. The maximum system voltage is 1000 V, so panels can be connected in strings according to the input range of the inverter. When sizing a string, always allow for the open-circuit voltage, which is higher at low temperatures. Installation and wiring of the photovoltaic array should be carried out by a person with electrotechnical qualifications. The panel itself is supplied without an inverter, cables and mounting structure.
Shipping
We ship the large and heavy panel as an oversized consignment. On receipt, check that neither the glass nor the frame is damaged.
Frequently asked questions
Is the panel suitable for an off-grid system?
Yes, but you need a suitable charge controller or inverter and batteries matching the system voltage. The panel itself supplies only direct current.
Can the panel be used on a roof as well as on the ground?
The manufacturer lists it for households, offices and larger solar projects. A structure that can bear its dimensions and weight is required.
What is the panel's protection rating?
IP68, that is, protection against dust and water. The operating temperature is from −40 to +85 °C.
