Solar panel monitoring system RT1

temperatureradiationfor photovoltaïc installations

Designed for rooftop PV installations Fits to a corner of any solar panel Smart digital duo-sensor Irradiance and back panel temperature ISO 9060 Class C The rugged housing of RT1 simply fits to the corner of a PV panel and contains the digital electronics. It also houses a sensor that reliably measures the incoming plane of array solar irradiance. The plug-in temperature sensor is easily attached to the back of the panel. RT1 is the perfect solution for monitoring the efficiency of commercial rooftop PV installations.
