Solar radiation & cloud cover forecasting

Reuniwatt offers cutting-edge solutions for high-resolution observation of the cloud cover and the solar irradiation, and short-term forecasting services. Acknowledged by industrials and researchers, they have been successfully deployed across all continents.


Satellite services

Geostationary satellite images are processed using our proprietary method SunSat™ to retrieve cloud cover and solar irradiance at the ground level at a kilometric resolution. Very handy for site monitoring, the data is available worldwide over the past, the present, and even the future!

All-sky imagers services

Our specifically developed sky imagers, including Sky InSight™ for 24/7 all-sky observation, enable to monitor the cloud cover with an unprecedented accuracy, and can be used to precisely forecast the solar plants’ production within the next few minutes with InstaCast™ method.


Our programme for 2020 is disrupted by the COVID-19 health crisis, but our motivation remains intact! See you soon, and let’s keep in touch virtually through our webinar series.
