Sunpal SP550M-72B All Black Solar Module, 550W

Описание на продукт

This model of the solar panel has 144 cells, coated with a layer of 3.2mm tempered glass that can withstand temperatures ranging from -40 to +85°C, wind pressure of 2400Pa, and snow load pressure of 5400Pa. The monocrystalline solar panel is made of crystalline silicon and is equipped with a short 30cm connecting cable, suitable for vertical panel installation. These panels are often considered the most efficient because the silicon crystal has a high efficiency in converting solar energy into electricity. They also feature high thermal resistance and long lifespan due to PERC technology, with degradation of less than 2% in the first year and 0.55% per year from year 2 to 25.

The panels are protected by PID (Potential Induced Degradation), meaning they are made from specially heat-stable materials that ensure long-term stability and efficiency of the photovoltaic panel. Additionally, panels with this protection are more heat-resistant and have better heat dissipation. The efficiency of this panel is 21.3%.
