The surface temperature sensor PT1000 is an adhesive foil sensor. It was designed for measurements on surfaces and is primarily used for temperature measurements of solar modules.
By installing the surface temperature sensor at the back of a solar module, the module temperature can be measured. The temperature of solar modules is crucial for their output, because the output decreases by 0.43 %/K with increasing temperature. By monitoring the temperature at the solar cells, conclusions can be drawn about the behaviour of the output curve.
The surface temperature sensor (STS) is designed for temperature measurements on surfaces. Installed at the back of a solar module, the STS measures the module‘s temperature. The temperature of the solar modules is crucial for their output which decreases by 0,43 % per Kelvin with increasing temperature (typical value for mono- and polycristalline modules).
Monitoring the module temperature allows conclusions to be drawn about the behaviour of the output curve.
