Digital Silicon Irradiance Sensor

Only if the real yield and the actual solar irradiance are measured in parallel you can realise component failures immediately.

Digital silicon irradiance sensor.

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

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. Selection table for digital irradiance sensors notes with the correct digital si sensor and. Based on the construction of the sensor element corresponding to a pv module they are ideal as reference for the monitoring of pv systems. Thermopile pyranometers commonly known as pyranometers used for scientific and meteorological use.

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. A recalibration is recommended at least every 3 years. Up to 1500 w m2 cell temperature measurement.

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

The sensors are built out of a monocrystalline si solar cell connected to a shunt. There are two types. Should damage be found that degrades the function or safety the sensor is to be replaced. 40 to 90 c working temperature.

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. 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.
