About Atonometrics

Innovation built for better solar performance

Since 2007, Atonometrics has developed innovative measurement technologies for PV performance monitoring, from soiling and irradiance to module power and I-V measurement.

Precision measurement for better PV performance

For nearly two decades, Atonometrics has developed measurement technologies specifically for the solar photovoltaic industry.

Founded in Austin, Texas, in 2007, Atonometrics develops solutions for measuring the factors that influence PV performance, including module power and I-V characteristics, soiling, irradiance, and temperature. The company combines specialized engineering, patented technologies, and industry research to address complex PV measurement challenges. 

Today, Atonometrics continues that focus as part of Kipp & Zonen, bringing specialized PV performance measurement expertise together with a broader portfolio of solar irradiance, weather, and environmental measurement technologies.

Solutions for deeper insight into PV performance

Atonometrics provides specialized measurement solutions that help solar professionals understand the factors influencing PV performance, from soiling and irradiance to module behavior, degradation, and temperature.

Explore solutions designed for different measurement needs across the PV plant, including optical and in-situ soiling measurement, PV reference cells, I-V curve measurement, module degradation monitoring, and temperature measurement.

Continuing the Atonometrics legacy

Atonometrics began with a focus on solving real-world measurement challenges encountered in photovoltaic systems. That same approach continues today.

From understanding how much power is being lost to soiling, to measuring irradiance behind bifacial modules, to observing module I-V behavior in operating arrays, Atonometrics technologies help solar professionals measure what is happening at the module and plant level.

Together with Kipp & Zonen's broader solar and environmental measurement portfolio, that expertise continues to evolve as PV plants become larger, more complex and increasingly dependent on reliable measurement.
