Digital Silicon Irradiance Sensor

Thermopile pyranometers commonly known as pyranometers used for scientific and meteorological use.

Digital silicon irradiance sensor.

Due to the low resistance of the shunt the cell operates next to short circuit. Comparison table new and old si sensors datasheet of our analog and digital silicon irradiance sensors si series. A silicon solar cell can be used as an irradiance sensor because the short circuit current is proportional to irradiance. And photovoltaic pyranometers known as irradiance sensors or solarimeters used to measure light and benchmark performance of photovoltaic instruments.

Only if the real yield and the actual solar irradiance are measured in parallel you can realise component failures immediately. Silicon irradiance sensors provide a simple and cost effective opportunity to monitor the performance of a solar system at any time. Until the year 2010 more than 15000 sensors were sold worldwide. Operating temperature range 35 to 80 c input power 8 to 28 vdc 12 to 28 vdc for 0 to 10 v analog output photovoltaic cell.

Should damage be found that degrades the function or safety the sensor is to be replaced. Silicon sensors for measuring the solar irradiation the spektron 210 320 and 485mb are silicon sensors used for measuring the solar irradiation. Pyranometers are sensors that measure solar radiation. Quick reference guide digital silicon irradiance sensor main data irradiance measurement.

Solar irradiance sensors si series version until october 2017 datasheet of our analog and digital silicon irradiance sensors si series. There are two types. Our silicon sensor is an affordable solution for mea surement of solar irradiance. Based on the construction of the sensor element corresponding to a pv module they are ideal as reference for the monitoring of pv systems.

Silicon irradiance sensor measurement uncertainty of irradiance does not apply for sensors with filter glass or polycrystalline cells 1 p erc nt agf d o h msu 2 p erc nt ag f d o h ms uvl external temperature compensation must be calculated on data acquisition side temperature coefficient at am 1 5. Up to 1500 w m2 cell temperature measurement. Silicon irradiance sensors si sensor show a cost effective but rugged and reliable solution for the measurement of solar irradiance especially for the monitoring of photovoltaic pv systems. The sensors are built out of a monocrystalline si solar cell connected to a shunt.

Sensor silicon solar irradiation sensor measurement description solar irradiance measurements for outdoor monitoring of pv systems irradiance measurement range 0 to 1500 w m 2. A silicon solar cell can be used as an irradiance sensor because the short circuit current is proportional to the irradiance. Digital silicon irradiance sensor si rs485 tc t measurement of solar irradiance general description since 1994 we have been developing and producing different types of silicon irradiance sensors.
