Solar Radiation and Temperature Meter – Overview

The IRM-1 is an indispensable unit for testing PV systems. By measuring solar radiation values, as well as panel and ambient temperatures, it provides the necessary data to convert the results into STC conditions. It is used as a tool in the PV plant design process, as well as in diagnosing panel shading problems. It performs well in harsh environmental conditions. Protection against dust and water is provided by the housing rated at IP65.  Measurement data from the IRM-1 can be transferred to a computer via the USB port. In addition, the device has a built-in wireless LoRa interface (Long Range) for automatic data exchange with the PVM-1020 meter over long distances (larger range than the Bluetooth technology). A built-in recorder has a memory for 5000 records.
