Solar power plant operators (Asset Managers, O&M service providers) and project developers face well-known technical difficulties concerning the irradiance measurement (with tools such as a pyranometer): wiring difficulties, poor data reliability and limited access to the database…. Taking into account the feedback from field experience, Reuniwatt has developed the Solar InCell™, a turnkey device that solves these down-to-earth complications linked with GHI and GTI measurement.


The Solar InCell™, a customer-oriented product

Equipped with an embedded computer, a solar panel and an integrated battery, the Solar InCell™ is compact, energetically autonomous and connected. Unlike the pyranometer, the Solar InCell™ is immediately operational and can be easily relocated. The data are cross-validated with satellite imagery. They can be visualized through our dedicated visualization platform or transmitted in your preferred format.

Valérick“The Solar InCell™ is a robust solution that provides a seamless source of irradiance measurement. Its autonomy, lack of cabling and its ease of use make it a very efficient product.”

Valérick Cassagne, Total – Development Manager BIPV 


The solution for solar project developers, O&M providers and Asset Managers


Myriad visualization platform – Solar InCell™ (black) and satellite (green) measurements.

We know that project developers need reliable and precise irradiance data for the different stages of the PV project development. The Solar InCell™ provides in situ irradiance measurements with a customizable granularity. Thanks to its two reference cells, it non only provides Global Horizontal Irradiance (GHI), but also Global Tilted Irradiance (GTI) in the chosen plan. Unlike a pyranometer, the Solar InCell™ is easily adjustable and can be moved without technical competency: just push the “Power” button and the device is up and running!

Raphael Alpin“I use Solar InCell™ irradiance measurements for due diligence reports presented to banks, investment funds and project certification organisms.”

The Solar InCell™ measurements are precious for the Performance Ratio calculation. In addition, the visualisation platform Myriad provides real-time and historical irradiance data visualisation, helping solar power plant operators detect plant-level failures.
