Fluke IRR1-SOL - Solar Irradiance Meter

The Fluke IRR1-SOL Irradiance Meter has been designed from the ground up to simplify the installation, commissioning, and trouble-shooting of photovoltaic arrays, measuring irradiance, temperature, inclination, and direction of the solar array in a single handheld tool. With a rugged, compact design, a protective carrying case, and an easy-to-read, high-contrast LCD screen to read measurements in direct sunlight, the IRR1-SOL can go where you go. The simple user interface, instantaneous solar irradiation measurements, and built-in temperature sensor make it easy to meet the IEC 62446-1requirements for testing, documenting, and maintaining photovoltaic systems. Additionally, the integrated compass and inclination sensor allows you to quickly measure and document roof and site orientation, pitch, and panel tilt while surveying, installing, or adjusting an installation.

Whether working on a roof-mounted system or on a large field installation, the IRR1-SOL is the single-handed solution that every solar installer and technician needs in their tool bag.

High Precision Mono-Crystalline Solar Sensor

Instantaneous irradiance measurements up to 1400 W/m².
 

Two Options For Temperature Measurement

Use the built-in temperature sensor or the external suction mount temperature probe to measure ambient and panel temperature.
 

Integrated Compass

Measure and document roof or site orientation.
 

Inclination Sensor

Know roof and PV panel tilt when surveying, installing, or adjusting the installation.

Use the IRR1-SOL for

Photovoltaic system design and surveying

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. Location, time of day, season, and weather conditions all influence peak sun hours. Use the Fluke IRR1-SOL to determine the actual solar irradiance (Watts/m²) and shading at the site to develop  a baseline.

Comparing and diagnosing

Even when installed correctly, a photovoltaic system may not be producing the expected electrical output. In order to produce the expected output the system needs to receive the correct amount of   irradiance energy to generate the DC voltage that is fed into the inverter.
