Fluke IRR1-SOL Irradiance Meter: An Essential Tool for Solar Panels
If you're surveying, installing, executing maintenance, or checking the performance of solar panels or a photovoltaic system, the Fluke IRR1-SOL Irradiance Meter is an invaluable tool. It provides the four critical measurements needed in one easy-to-use tool.
- Solar Irradiation Measurements: Make instantaneous measurements to determine the watt per square meter solar irradiation, a requirement stipulated by the IEC 62446-1 standard.
- Temperature Measurement: Measure the temperature either by placing the meter directly on the panel or by connecting the external probe.
- Cardinal Direction and Tilt Verification: Find the cardinal direction with the built-in compass, and verify the inclination of a roof or panel with the tilt function.
- Determining the Expected Solar Production: To find the expected production at a site, determine your solar resource while taking shading into account. The solar resource is measured in peak sun hours: the number of hours per day with 1,000 watts generated per square meter of solar array. Factors such as location, time of day, season, and weather conditions all influence peak sun hours.
Includes:
- Solar Irradiance Meter
- External Temperature Probe with Suction Cup
- Carrying Case with Sholder Strap
- 4 x AA Batteries
