Digital Silicon Irradiance Sensor

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

Digital silicon irradiance sensor.

Up to 1500 w m2 cell temperature measurement. Silicon irradiance sensors provide a simple and cost effective opportunity to monitor the performance of a solar system at any time. Should damage be found that degrades the function or safety the sensor is to be replaced. Our silicon sensor is an affordable solution for mea surement of solar irradiance.

Selection table for digital irradiance sensors notes with the correct digital si sensor and. Thermopile pyranometers commonly known as pyranometers used for scientific and meteorological use. 40 to 90 c working temperature. 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 recalibration is recommended at least every 3 years. The sensors are built out of a monocrystalline si solar cell connected to a shunt. Comparison table new and old si sensors datasheet of our analog and digital silicon irradiance sensors si series. Based on the construction of the sensor element corresponding to a pv module they are ideal as reference for the monitoring of pv systems.

Only if the real yield and the actual solar irradiance are measured in parallel you can realise component failures immediately. A silicon solar cell can be used as an irradiance sensor because the short circuit current is proportional to irradiance. Silicon sensors for measuring the solar irradiation the spektron 210 320 and 485mb are silicon sensors used for measuring the solar irradiation. And photovoltaic pyranometers known as irradiance sensors or solarimeters used to measure light and benchmark performance of photovoltaic instruments.

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

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. Pyranometers are sensors that measure solar radiation. Until the year 2010 more than 15000 sensors were sold worldwide.
