Digital Silicon Irradiance Sensor

Due to the low resistance of the shunt the cell operates next to short circuit.

Digital silicon irradiance sensor.

Thermopile pyranometers commonly known as pyranometers used for scientific and meteorological use. Solar irradiance sensors si series version until october 2017 datasheet of our analog and digital silicon irradiance sensors si series. 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 irradiance.

Comparison table new and old si sensors datasheet of our analog and digital silicon irradiance sensors si series. Silicon irradiance sensors provide a simple and cost effective opportunity to monitor the performance of a solar system at any time. The sensors are built out of a monocrystalline si solar cell connected to a shunt. Based on the construction of the sensor element corresponding to a pv module they are ideal as reference for the monitoring of pv systems.

A silicon solar cell can be used as an irradiance sensor because the short circuit current is proportional to the irradiance. 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. 40 to 90 c working temperature. Quick reference guide digital silicon irradiance sensor main data irradiance measurement.

And photovoltaic pyranometers known as irradiance sensors or solarimeters used to measure light and benchmark performance of photovoltaic instruments. 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. Only if the real yield and the actual solar irradiance are measured in parallel you can realise component failures immediately. There are two types.

Silicon sensors for measuring the solar irradiation the spektron 210 320 and 485mb are silicon sensors used for measuring the solar irradiation. Up to 1500 w m2 cell temperature measurement. 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. Our silicon sensor is an affordable solution for mea surement of solar irradiance.

A recalibration is recommended at least every 3 years. Pyranometers are sensors that measure solar radiation. Should damage be found that degrades the function or safety the sensor is to be replaced.
