(The above data is based on the laboratory standard test environment)

For field connections,use minimun No.12AWG copper wires insulated for a minimum 90℃

Standard Test Conditions:

AM=1.5 IRRADIANCE=1000W/m2 Temp.=25℃
(The size is manually measured and there is a certain error.）

Difference

16V 100W VS 18V 100W

18v100W, 4*9，36Cells.
16v100W, 4*8, 32Cells.

（When the 16v solar panel is electrically conductive, the requirements for sunlight intensity are higher than 18v.）

The main feature is light, easy to carry, and small space occupation.

Due to the particularity of the material. Flexible solar panels are not recommended to be placed on the roof or outdoors for a long time.

If placed on a caravan. Need to use high temperature resistant glass glue to isolate the high temperature of the surface.

Product display（18V）

Flexible solar panels cannot directly contact the surface of the roof.
The high temperature resistant cotton glue needs to be pasted under the solar panel to isolate the high temperature of the roof.
