Product Overview: Fluke IRR1-SOL, IRR2-BT Solar Irradiance Meter, PV Site Surveyor
Fluke IRR1-SOL, IRR2-BT Solar Irradiance Meter, PV Site Surveyor
The installation, commissioning, and troubleshooting of photovoltaic arrays have been made simpler by the Fluke IRR1-SOL and IRR2-BT Irradiance Meters, which measure irradiance, temperature, inclination, and direction of the solar array in a single handheld tool. These thorough PV site surveyors can go anywhere thanks to their durable, portable design, sturdy carrying bag, and easy-to-read, high-contrast LCD screen for reading measurements in direct sunshine. Meeting the IEC 62446-1 criteria for testing, documenting, and maintaining photovoltaic systems is made simple by the user-friendly interface, real-time measurements of sun irradiation, and built-in temperature sensor. Fluke Irradiance Meters are the all-in-one tool that every solar installer and technician needs in their toolbox, whether they’re working on a roof-mounted system or a big field installation.
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
Measure and document roof or site orientation
Know roof and PV panel tilt when surveying, installing, or adjusting the installation

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.
Measure your system’s electrical characteristics and the array’s actual power output after installation to ensure it is performing as intended. The current-voltage (I-V) curve of a solar array determines how well it performs. The quantity of solar irradiation required to determine the I-V curve of the power output can be obtained using an irradiance meter. The Fluke SMFT-1000 Solar Multifunction PV Analyzer can wirelessly communicate recorded irradiance and temperature measurements with the IRR2-BT to rapidly determine the I-V curve of the panels being tested. A solar system can not be producing the desired amount of electricity even when it is placed properly. 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
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.
