If you’re surveying, installing, executing maintenance or checking performance of solar panels or a photovoltaic system, the Fluke IRR1-SOL Irradiance Meter gives you the 4 critical measurements needed all in one easy-to-use tool. Make instantaneous measurements to determine the watt per square meter solar irradiation, required by IEC 62446-1 standard. Measure temperature by either placing the meter directly on the panel or by connecting the external probe.
Test that PV systems are performing to their optimal power output as well as operating safely with the Fluke SMFT-1000 multifunction tester with I-V curve tracing.
