New energy technologies, like solar, require specialized test tools to efficiently provide critical measurements. The new Fluke (Everett, WA) IRR1-SOL Irradiance Meter has been designed from the ground up to simplify the installation, commissioning, and troubleshooting of photovoltaic arrays by measuring irradiance, temperature, inclination, and direction of the solar array with a single handheld tool.
The simple user interface, instantaneous solar irradiation measurements, and built-in temperature sensor make it easy to meet IEC 62446-1 requirements for testing, documenting, and maintaining photovoltaic systems. Additionally, the integrated compass and inclination sensor allow technicians to quickly measure and document roof and site orientation, pitch, and panel tilt while surveying, installing, or adjusting an installation.The Fluke IRR1-SOL Solar Irradiance Meter is ideal for:
- Photovoltaic system design and surveying — to find the expected production at a site, technicians must determine the solar resource while taking shading into account. The Fluke IRR1-SOL measures the actual solar irradiance (Watts/m2) and shading at the site to develop a baseline.
- Measuring — once the system is installed, the IRR1-SOL ensures it is operating as designed by taking the critical measurements needed when determining its power output.
- Comparing and diagnosing — even when installed correctly, a photovoltaic system may not be producing the expected electrical output. The IRR1-SOL confirms the correct amount of irradiance energy is being received to generate the DC voltage that is fed into the inverter.
