Fluke IRR1-SOL Solar Irradiance Meter
The Fluke IRR1-SOL is a compact, rugged, and easy-to-use solar irradiance meter designed for installers, technicians, and engineers working with photovoltaic systems. It provides precise measurements of solar irradiance, module and ambient temperature, array orientation, and tilt, helping to simplify installation, testing, documentation, and troubleshooting of solar panels in compliance with IEC 62446-1 standards.
Description
The Fluke IRR1-SOL is an all-in-one solution for solar energy professionals, offering instant and accurate measurements of solar irradiance (up to 1400 W/m²), ambient and PV module temperature, as well as roof and panel orientation and tilt. Its high-contrast LCD display ensures clear readings even in direct sunlight, while its rugged, compact design makes it portable for fieldwork.
The device integrates a precision monocrystalline solar sensor, a built-in temperature sensor, an external temperature probe option, a compass, and an inclination sensor. These features allow users to efficiently determine peak sun hours, calculate IV curves, and evaluate shading effects at a site. By measuring solar resource accurately, technicians can optimize system performance and verify that panels receive adequate irradiance to generate expected electrical output.
The IRR1-SOL also simplifies site surveying and system installation by providing quick measurements of roof pitch, panel tilt, and array orientation, ensuring accurate documentation for compliance and performance tracking. Whether commissioning a new PV system, conducting routine maintenance, or troubleshooting underperforming panels, the meter ensures reliable, repeatable results in a compact, user-friendly package.
