Sensor for Solar Irradiance and Temperature PT100 by GSL-IT-W Radio transmitter module

This sensor can detect Solar Irradiance and Temperature and it can transmit the values of the sizes to a radio-receiving module which sends them to a processing unit. It’s supplied by an internal battery.
Thanks to it, is possible detecting accurately the Irradiance and the working Temperature of the panels, primary parameters for calculating the efficiency of photovoltaic installations.

Only by considering these measurements, it is possible monitoring the real performance of the installation and notice eventual problems which can vary the real efficiency than theoretical values.

The irradiance is detected by means of a sensor protection by an optical glass window, inserted in a waterproof structure, with protection degree IP65. Within the module is also detected the sensor temperature, useful for an accurate compensation. The measure of the external panel’s temperature is carried out by a PT100 probe, provided as optional accessory and mounted outside the module.

The associated radio-receiving module implements also the signal of warning when remote sensor’s battery is getting discharged, this occurs a few weeks before the complete discharge.
