A silicon solar cell can be used as an irradiance sensor, because the short-circuit current is proportional to irradiance. Our sensors are built out of a monocrystalline solar cell connected to a shunt. Due to the low resistance of the shunt the cell operates next to short circuit.
The compensation is realized by using a specific temperature sensor laminated to the rear side of the solar cell.
Mono Crystalline or polycrystalline Silicon Solar Cell (50 x 50 mm²) laminated under specialSolar Glass with excellent UV resistance and long-term stability Plain integration into the top cover of the boxAdvanced weatherproof junction box made of UV resistant material with cable gland andscrew-less terminal for the connection of the measuring cableHigh precision shunt resistor directly soldered to the terminals of the cellLinear output signal in the range 0...1500 W/m²Individual calibration of each sensors in the natural sunlight close to AM 1,5 spectrum bymeans of a compatible calibrated reference cellAccuracy of monthly sums compared to a W.M.O. class 1 Pyranometer (e.g. CMP 11)according to ISO 9060: better ±5 %Very small drift of <0.3 / year (experience since 1989)Integrated signal amplifier with output signal 4...20 mA Loop powered 2wire
