What is the minimum operating temperature of the SPRING panel?

The minimum operating temperature of the SPRING panels is -40 ° C. 

DualSun has passed the IEC 61215 standard which includes thermal cycling from -40°C to +85°C in the following two tests.

Please consult the IEC 61215 test results

 

Note: When coupled with a heat pump, the temperature of the heat transfer fluid circulating through the panels may be negative. Frost may then appear on the surface of the panel. This is not a problem at night, but during the day it can affect the photovoltaic production. It is therefore important that the heat pump used has a defrosting program for its source.
