Cooling Module

The Solkraft Cool Module is a high efficiency solar panel with integrated passive cooling system that can perform optimally at high temperatures. 

Heat Losses
As the sun heats up an ordinary silicon cell module during the day, the cell voltage drops and the power output is dramatically reduced. Research shows an average “temperature coefficient loss” in the power output of-0.5%/°C for all modules with silicon cells. To solve this heat-loss problem, Solkraft Innovation has developed a passive cooling system which significantly reduces the cell operating temperature.

Cooling Fins
The unique design of the patented Solkraft Cool Module transports heat from the cells to the module backside where an aluminum fin heat sink disperses the heat through radiation and convective air flow. Local air movements will further enhance the heat dissipation from the module. This passive cooling counteracts the voltage reduction caused by rising temperature and increases the power output with 10% to 15% in warm climates.

The Solkraft Cool Module is a frameless module with integrated aluminum fins. The Solkraft Cool Module has a low Nominal Operating Cell Temperature 34°C as compared to 45°C in standard modules. This implies we will achieve a longer module life time due to the lower operating temperature of the module. The Solkraft Cool Module has a higher rigidity due to the integrated passive cooling system. The fin geometry has been optimized for effective heat transfer during natural convective and forced air flow (such as wind).
