Advantage

The 310-watt polycrystalline photovoltaic panel contains 72 cells with professional product qualification certification.
The multiple crystals are what cause the panels to have that ‘marbled’ blue appearance. Just like monocrystalline panels, polycrystalline panels will contain either 60 or 72 cells.
With the development of technology, quality improvement, the power output of polycrystalline solar panels reached 310 watts

Details

Our solar panels have diodes in order to prevent current recoil and stabilize the current;
The most suitable angle for solar panel mounting is the horizontal 45 °;
Solar panels should be kept clean during normal use to ensure the surface is not blocked and extend their life.
Most important thing about cleaning the solar panels:
1-Cannot walk on top of it
2-No high water pressure is used
3-No rough cleaning tools
4-Power cleaning products are not used
Wash with a light water spray and use a light mop in case a thin soap is needed.
