Technische Beschreibung
The CS240 consists of a Pt-1000 class A PRT encased in an aluminum disk. The disk protects the PRT, particularly during installation when pulled through conduit, and promotes heat transfer from the surface. An adhesive tab on the disk fastens the CS240 to the measurement surface. If the temperature may exceed 70°C, Extreme sealing tape is also required to secure the probe.
The CS240 provides PV stakeholders with highly accurate back-of-module temperature, even at long cable lengths, for use in power performance modeling and simulation of solar energy applications. Back-of-module temperature is critical for any evaluation of effective irradiance and power conversion.

-
A hot spot is caused if a cell in series is under-producing due to shading and gets reversed bias due to the other producing cells. For bifacial modules, as long as the front face is not shaded, all the cells should be producing and covering a small area on the back side and should not cause a severe mismatch.
-
Even when three-pt calibration isn’t ordered, when we build the probes, we perform a final test to verify that they are reading within 0.3°C of our calibrated reference sensor at room temperature.
-
NIST traceability provides an assurance of accuracy. This is especially desirable in accordance with IEC 61724, which is a solar energy generation monitoring specification that requires calibrated sensors.
