Solar training


The annual solar training that we co-organise with the research center O.I.E from Mines ParisTech is scheduled from January 25 to 29, 2021.

It is the perfect occasion to discover the science related to surface solar radiation, ground sensors, satellite imagery, solar mapping, solar variability and forecast and the solar data processing. 

Please contact Dr Mathilde Marchand to save your seat!

global horizontal irradiation anomaly maps over france

September 2020

Anomaly maps service

This service is useful to get to know if last month's solar trend was rising or decreasing in comparison to the long-term period.
⇒ Last month's anomaly map is delivered every month by Marion from SoDa team.
Do not hesitate to contact us if you are interested in anomaly map with your variables of interest (solar radiation, ultraviolet, weather) and over the region of your choice.

IN SUN WE TRUST solar rooftop simulator IS NOW covering all france

July 2020



SoDa team is very happy to introduce you to In Sun We Trust solar cadastre which covers now all roofs in France. This achievement is the result of several years of work and calculation using our HelioClim-3 solar radiation database

This allows a very precise estimation of the potential production of photovoltaic panels in any rooftop, calculated from 15 years of irradiation data, and considering all the effects of local shading (of buildings, vegetation, and relief) at a resolution of 20-25 cm.

We are very proud and thankful to In Sun We Trust for their trust and collaboration, to allowed us to participate in the establishment of this French solar cadastre.


June 2020



Our artificial intelligence solar forecast service delivering solar radiation time series for today and tomorrow is now available for all solar radiation components:

  • Global, direct, diffuse and reflected irradiation,
  • Over horizontal, tilted, and normal planes.

This service is based on a machine learning method called Gradient Boosting

Solar AI forecast service uses as inputs :

You can check AI Forecast results updated in real-time over Petrolina, Brazil, and Carpentras, France here.

improvements and deliverables

June 2020



The SoDa development team is working hard to deliver new features to our services:

 Improvement of the quality of our new solar radiation forecast service :
  • several time steps available, from 1 to 60 minutes
  • direct and diffuse irradiations available at horizontal, tilted and normal planes
  • considers the relief shadows.
 For the Helioclim-3 solar radiation time series obtained through automatic access, you can now choose the meteo parameters that you wish in the output file.
 SoDa speed of web services increased.
All the informations about these improvements are available at our release notes page.



Do not hesitate to contact us for more information about our new developments and services.
