PVS-1 Irradiation Sensor
PVS1 is a solar irradiation sensor based on photovoltaic technology. A crystalline silicon cell is used to measure the solar irradiation, so as to match the same typical behaviour as photovoltaic modules in terms of light wavelength response.
The sensor, installed with the same tilt and azimuth of the PV modules, measures the solar irradiation and provides the measurement as an analog electrical signal by means of its mV or mA output to be connected to an opportune measuring device such as the environmental module (VMU-P) of the Carlo Gavazzi’s Eos-Array/ Eos-Web system.
PVS1 is a ruggedized sensor with an aluminium case and an UV resistant encapsulation so as to avoid issues driven by adverse weather conditions and humidity; installation is fast, thanks to the clamping system designed to fit easily the photovoltaic module’s frame.
The 3% (mV output) or 4% (mA output) accuracy is stable as time goes by, thanks to a special anti-ageing treatment. A calibration certificate according to the relevant guidelines is available on request.
