Fluke IRR1-SOL Solar Irradiance Meter
Professional Solar Irradiance Meter for PV Installation and Maintenance
The Fluke IRR1-SOL Solar Irradiance Meter is designed for solar PV installers, renewable energy technicians and electrical engineers who need fast and accurate solar measurements when installing, commissioning and maintaining photovoltaic systems. Combining irradiance, temperature, compass and inclination measurements in a single handheld instrument, the IRR1-SOL simplifies solar testing and helps meet IEC 62446-1 requirements for PV system verification and reporting.
Designed for Complete Solar Site Assessment
With a high-precision mono-crystalline solar sensor, the IRR1-SOL measures solar irradiance up to 1400W/m² while also monitoring panel or ambient temperature using either the built-in sensor or the included external temperature probe. The integrated compass and inclination sensor allow technicians to document roof orientation, panel tilt and site conditions during surveys, installation and troubleshooting. Its rugged design and high-contrast display make it ideal for outdoor use in direct sunlight.
Why choose the Fluke IRR1-SOL?
The Fluke IRR1-SOL combines irradiance, temperature, inclination and compass measurements in one compact handheld tool, reducing the need for multiple instruments on site. By providing the key data required to assess photovoltaic system performance, calculate expected output and identify potential issues, it helps solar installers and PV technicians streamline commissioning, maintenance and troubleshooting while supporting accurate reporting and documentation.
