Solar Panel Test Chambers Provide Up To 65% Energy Savings

Using CSZ’s patented Tundra® refrigeration system provides the ability to test product down to -45°C (-45°F) with a load and a single compressor where traditional test chambers for solar panel testing require a cascade refrigeration system. Documented energy savings of 47-66% were obtained by following the test specifications below with CSZ test chambers and a Fluke power monitoring system.

*Time based upon a chamber that meets max ramp rate requirements. Data compares the energy savings of operating at 15HP cascade compared to a 10HP Tundra in an empty chamber. Cost savings calculations based upon 13 cents per Kwh.

A total of $560 - $860 dollars can be saved completing each of the above tests in a CSZ chamber with Tundra system.
