Our Engine
THE SOLAR ENGINE
SAUREA for "Solar AUtonomous REliable Applications";
an autonomous engine with a wide range of applications
SAUREA, THE GREEN DEEPTECH START-UP
A true meeting of societal ambition and solar technology...
DeepTech is the DNA of SAUREA, in perfect harmony with the i-Lab Innovation Competition obtained in 2015, Distinction for innovative technology company creations:
SAUREA is half private, half spin-off with a strong link to the scientific world through its historical partnership with the École Normale Supérieure de Cachan and GeePs-Centrale Supélec
Our intellectual property strategy
In order to be competitive on the international scene, SAUREA relies not only on an essential weapon, its patents and its strong technical guarantee: this strategy allows it to create value with the engine invented, designed, industrialised and manufactured by SAUREA.
SAUREA AND OTHER ENGINES
A motor like no other... self-propelled without wear and tear, without electronic power circuits
There are no devices such as fast-wearing commutator brushes or sensitive electronic components in this solar motor with its high reliability potential.
Only the use of photovoltaic (PV) cells, both for the energy source (from external PV panels) and for the current routing in the phases, makes the SAUREA motor a disruptive & "low tech" motor.
Indeed, as early as the 1960s, patents were filed for electric motors, with or without collectors, self-powered by photovoltaic (PV) cells, but their poor performance did not allow them to find applications.
Then came electronically controlled brushless motors powered by external photovoltaic panels
The idea of running an electric motor on solar energy is not new.

THE SAUREA SOLAR ENGINE
OPERATION OF THE SAUREA ENGINE
An autonomous solar motor to drive mechanical devices
Presentation of SAUREA
This new generation of motor runs on the sun and can be used to drive small mechanical devices such as pumps, foggers, ventilation turbines, stirring devices, small agricultural machines, etc.
It provides mechanical energy:
- In off-grid sites, mainly in rural areas
- In urban areas for an energy mix
ENGINE POWER
A range of engines dictated by its power
MOTOR ONLY
The motor alone develops only a few watts, insufficient to drive any mechanical or hydraulic device
Power = a few Watts
MOTOR + PANELS
The addition of PV panels directly connected to the engine allows a significant increase in power
Power over 80W
Benchmarks
The first engine in the range has a power equivalent of
the human motor force or the muscular power developed by a cyclist pedalling on a flat course
Why SAUREA?
SAUREA's vocation is to provide a direct response to
major challenges for the planet and represents a great opportunity to
societal progress with its response to societal & climate challenges:
energy transition, sustainable energy, securing systems
motorised for a sustainable world in line with the UN SDGs.
