Solar Monitoring

The most important measurement parameter is irradiation. Since PV systems are becoming ever larger, the accuracy of the irradiation measurement is increasingly important for the efficiency of the system. Wind cools the temperature of the module and must therefore be included in the efficiency calculation. Precipitation leads to contamination or covering (snow). With increasing temperature, the performance of the solar module decreases. Therefore, it is important to measure the temperature of the solar module in addition to the air temperature.

Integration of our Sensors into PV/Solar Monitoring Systems

Many photovoltaic system providers throughout the world use our sensors. In general, MODBUS interfaces are used to transfer measurements to the PV controller. On request, we integrate manufacturer-specific protocols as a plug & play interface.

Why is the WMO standard required in such applications? Because the large measuring range is necessary for irradiation, in order to measure the actual effi ciency of the PV system. And because the service life of the system is intended to be more than 10 years. This requirement also applies to the sensor technology.

Which alternative sensor technologies are useful? GHI: Global irradiation on the horizontal surface GTI: Global irradiation, tilted. And thus aligned to the irradiation angle of the sun. DHI: Diffuse Horizontal Irradiation Together with the WS600, these sensors are transmitted via a Modbus interface to the data acquisition unit / controller of the PV system.
