The Longi Solar photovoltaic module with a power of 365 W is made of 120 cells. The manufacturer allows installation both vertically and horizontally. The parameters of the module are confirmed by appropriate certificates and have European trademarks. The 9 BB technology used allowed the manufacturer to fit a larger area of photovoltaic cells on a panel of a size currently considered standard. A larger number of Bus Bars reduces energy losses in the module itself. Longi Solar, thanks to the improvements used, has reduced the possibility of hot-spots. The high efficiency of power generation and the high quality of the modules ensure long-term reliability.
