This all-in-one device measures solar irradiance, panel temperature, tilt, and direction—helping you optimise every installation and ensure long-term system performance. With wireless connectivity and instant reporting, the FLIR PV78 not only saves time but also improves accuracy and professionalism in your daily workflow.

Instant Solar Irradiance Measurements
Accurate solar irradiance data is essential when working with PV systems. The FLIR PV78 Solar Irradiance Meter delivers fast, reliable irradiance readings ranging from 50 to 1400 W/m². Fully compliant with IEC 62446-1 standards, it helps you verify site conditions, check system performance, and ensure panels are positioned for maximum energy production.
With the FLIR PV78, there’s no waiting around—get instant results and make informed decisions on-site.
More Than Just Irradiance: Temperature, Tilt, and Direction
The FLIR PV78 offers more than basic measurements. It also monitors panel temperature, either by placing the device directly on the panel or using an external probe for continuous readings. Since high temperatures can reduce efficiency, keeping track of this is crucial for system performance and longevity.
The built-in tilt sensor and digital compass make alignment simple. The FLIR PV78 Multifunction Tester quickly verifies the angle and orientation of solar panels, ensuring they’re set up to capture the most sunlight possible.

Stay Connected with FLIR METERLiNK
Thanks to integrated FLIR METERLiNK Bluetooth technology, the FLIR PV78 connects seamlessly to your mobile device. Using the FLIR METERLiNK app, you can view live readings, generate detailed reports, and share results instantly with your team or clients.
