Digital Silicon Irradiance Sensor

Solar irradiance sensors si series version until october 2017 datasheet of our analog and digital silicon irradiance sensors si series.

Digital silicon irradiance sensor. Our silicon sensor is an affordable solution for mea surement of solar irradiance. Thermopile pyranometers commonly known as pyranometers used for scientific and meteorological use. Only if the real yield and the actual solar irradiance are measured in parallel you can realise component failures immediately. 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.

Based on the construction of the sensor element corresponding to a pv module they are ideal as reference for the monitoring of pv systems. 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. Comparison table new and old si sensors datasheet of our analog and digital silicon irradiance sensors si series. 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. A recalibration is recommended at least every 3 years. 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. There are two types.

Due to the low resistance of the shunt the cell operates next to short circuit. Pyranometers are sensors that measure solar radiation. And photovoltaic pyranometers known as irradiance sensors or solarimeters used to measure light and benchmark performance of photovoltaic instruments. A silicon solar cell can be used as an irradiance sensor because the short circuit current is proportional to the irradiance.

Selection table for digital irradiance sensors notes with the correct digital si sensor and. Should damage be found that degrades the function or safety the sensor is to be replaced. Until the year 2010 more than 15000 sensors were sold worldwide. Quick reference guide digital silicon irradiance sensor main data irradiance measurement.

40 to 90 c working temperature. 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. A silicon solar cell can be used as an irradiance sensor because the short circuit current is proportional to irradiance.
