Cell Technology 108 Half-cell MONO PERC

Nominal Power 405~415Wp

Wind/Snow Load 3600/ 5400 Pa


Module Efficiency Up to 21.3%

Temperature Coefficient -0.34

Temperature Coefficient

The “temperature coefficient” describes the percentage of power output that is lost by a specific solar panel as the temperature rises above 77°F. It specifies just how heating affects the module power, and provides a number showing how much the module power is reduced if the ambient temperature is increased by one degree Celsius. The lower the temperature coefficient, the better.

Temperature Tolerance -40°C up to 85°C

Temperature Tolerance

The ranges in “temperature tolerance” indicates expected operating temperature of the PV module. In order words, modules are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature.
