Something about solar LED street light

 LED module is a hot-sale product in our company.Because it can be used in different places and with little volume for transportation.And it’s cheap and high quality.So let’s focus on the solar LED street light and I will talk about it from three aspects--main structure,battery type and advantage.

 Structure:solar panel lamp body ,MPPT, battery.

 Fission LED solar street light.

 All in one LED solar street light.

 Let's look at the solar panel raw material:

Single crystal silicon color: jet- black,stripe,sinned wire ,the efficiency of converting solar energy into electricity is 19 percent.

Poly silicon color: blue black stripe wire ,the efficiency of converting solar energy into electricity is 17 percent.

Sanpao panel color: no jet- black,no stripe,no sinned wire ,the efficiency of converting solar energy into electricity is 21 percent.

 There are two Silicon Wafer Size:   156mm×156mm   4w/pieces

                              156mm  4.2/pcs (hexagon)

  Next is battery type.There are two type of solar battery.The first is acid battery,acid battery includes lead-acid battery and gel battery.Lead-acid battery can work in 0~55℃. The gel battery can work in -20~55℃.The second is lithium battery,it can work in 0~55℃and LiFePo4 battery is -20～55℃.

The acid battery’s efficacy is 0.7 and Lithium battery is 0.9.

Advantage: waterproof, can be single crystal ,easy to dissipate heat,use the solar power to save electricity and protect the earth’s resources, no need to pull wire,installation is extremely convenient.
