SOLAR RADIATION SENSOR
Starting from 1st November new models of sensor are available: Si-V-10TC, Si-V-10TC-T, Si-I-420TC, Si-I-420TC-T.
For the complete list of available sensors see the datasheet.
From the same date, the sensors will be distributed with original M&T label
Mode of operation
A silicon solar cell can be used as an irradiance sensor, because the short-circuit current is proportional to the irradiance.
Our sensors are build out of a monocrystalline Si solar cell connected to a shunt. Due to the low resistance of the shunt the cell operates next to short-circuit.
To minimize influences of temperature to the measuring signal all of our sensors with the extension „TC“ have an active temperature compensation via a temperature sensor laminated to the back surface of the solar cell.
All sensors are calibrated in artificial sunlight against a reference cell calibrated at the Physikalisch-Technische Bundesanstalt (PTB, National Metrolo gy Institute of Germany).
The solar cell is embedded in EthylenVinyl-Ace tat (EVA) between glass and Tedlar.
The laminated cell is integrated into a case of powder-coated aluminium. Therefore the sensor construction is comparable to that of a standard PV module.
The electrical connection is realized by a 3m cable or a water proof (IP67) connector
Optional Temperature Measurement
Additionally to the irradiance measurement our silicon sensors with the extension “-T” are able to measure the temperature of the solar cell using a temperature sensor laminated to the back of the cell.
This solar cell temperature can approximately be used as module temperature.
