Solar panel PNI Green House 445 W monocrystalline, silver frame, 1903 × 1134 mm
Code: PNI-SRP-445WProduct detailed description
PNI Green House 445 W is a monocrystalline photovoltaic panel in a silver frame that converts sunlight into direct current for a residential or commercial photovoltaic power plant. With an efficiency of 22.02%, it delivers a power output of 445 W per module, so you need fewer panels to build a larger array.
The panel is designed for long-term outdoor operation. It functions in a temperature range from −40 to +85 °C and has an IP68 rating, so it is not affected by dust or water. It is suitable for the roof of a family house, for flat roofs of companies, and for off-grid installations that are not connected to the distribution grid.
With dimensions of 1903 × 1134 mm and a thickness of 30 mm, it belongs to the large-format modules and weighs 24.2 kg. Therefore, ensure a sufficiently sturdy structure and two people for handling when installing it.
Connection and Installation
The electrical values of the panel 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 the panels can be connected in strings according to the input range of the inverter. When dimensioning the string, always consider the open-circuit voltage, which is higher at low temperatures. The installation and connection of the photovoltaic field must be carried out by a person with electrical qualifications. The panel itself is delivered without an inverter, cables, or mounting structure.
Transport
The large and heavy panel is transported as an atypical shipment. When receiving it, check whether the glass or frame are not 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 only delivers direct current.
Can the panel be used on a roof and on the ground?
The manufacturer recommends it for homes, offices, and larger solar projects. A structure that can support its dimensions and weight is required.
What is the panel's protection rating?
IP68, meaning protection against dust and water. The operating temperature is from −40 to +85 °C.
