Our mission


Heat is the first primary form of energy consumed in the World; it represents around 50% of the total.
Today, 85% of this heat energy depends on fossil fuels.
The use of renewable energies as an alternative to fossil fuels is a priority focus for reducing CO2 emissions.
Efficient energy savings combined with solar energy – an inexhaustible, competitive, and local resource – provide a lasting response to the sustainability of human activities.

Our values


We build our growth by providing sustainable and innovative heat solutions tailor-made for each of our customers.


Our aim is to revolutionize the renewable heat market to provide a concrete and decisive response to the challenge of reducing CO2 emissions.


We are committed every day to perfecting the design of our power plants and optimising their operation, thereby creating value for our customers in the long term.


We believe in the need to undertake significant social and environmental commitments to give meaning to our growth and maintain absolute integrity in all circumstances.

Our job


We offer two kinds of complete solutions to meet the expectations of each client:

We provide solar heat via meter, bearing the full costs of studies, implementation, and operation (third-party investment).

We provide a turnkey installation combined with a full maintenance and servicing solution over time with guaranteed performance.

Our expertise

Modelling, engineering, and piloting


The precise modelling of our systems and their interaction with our clients’ processes and networks allows us to provide a suitable design and optimized operation.

Design engineering

Our projects require extensive mastery of various technical skills: solar, hydraulic, thermal and automation engineering. These skills allow us to select the most suitable technologies for the operation of our clients' heat processes and networks, and for optimizing their design and set-up.

Control & command system

We define and implement a dedicated and optimized management solution for each project, making our plants' equipment efficient and reliable, in coordination with our clients' equipment.

Our Research & Development programs

A third of our team members is involved in Research & Development programs winning national and European competitions:


Investment for the Future program managed by ADEME (2016)

ISORC project

Call for Research project managed by ADEME and ANR (2017)

SCALE&MIX project

ADEME Innovation competition (2018)


European Union LIFE call for projects (2018)

As member of the working groups of the International Energy Agency (IEA) dedicated to large solar thermal systems, we are involved in promoting and establishing standards for our profession. (Task 49 – Solar Heat Integration in Industrial Processes, Task 55 – Integrating Large SHC Systems into DHC Networks, Task 64 – Solar Process Heat).
