durable polycrystalline solar panel supplier for street lamp

Half-cell 144cells

The area of the 144 CELLS solar panel is 2㎡ and the maximum working voltage of the module is 40V

Half-cell 120cells

The area of the 120CELLS solar panel is 1.6㎡, and the maximum working voltage of the module is 33V

The half-cell component can be obtained by connecting the standard cell in series after cutting, which can reduce the power loss. The component power is 5-10 watts higher than the conventional component of the same version. It is the most efficient component technology that is easy to realize large-scale mass production and has high-cost performance

MC4 connector with Waterproof and flame retardant, high corrosion resistance, excellent electrical conductivity, can last for 25 years

The junction box is made of ultra-long and durable industrial PVC material, which can provide good protection and reduce the chance of failure due to the connection of the line

The aluminum alloy frame is lightweight, high strength and corrosion resistance, which can reduce the overall weight of the components and strengthen the resistance of the components

High conversion efficiency of the cell

The 156.75mm high-efficiency battery sheet is prepared into half cell for assembly, the overall internal resistance of the component will be reduced, and the performance of the solar panel will be effectively improved
