SAUREA


The innovative SAUREA solar motor converts directly solar energy into mechanical energy with 20 years maintenance free.

SAUREA means Solar Autonomous Reliable Applications The start-up is less than 3 years old with a capital of 335 000 € located in Burgundy at Auxerre with a second Research & Development Office at the Business Innovation Centre in Occitanie at Montpellier, the second World Innovation Incubator. SAUREA designs, develops and manufactures the most durable and reliable solar motor in the world : The simplicity of the SAUREA photovoltaic motor makes it ideal candidates for fully autonomous applications requiring thousands of operating hours without maintenance, like water pumping. SAUREA photovoltaic motors converts sunlight energy into mechanical energy without need of mechanics or electronics conversion. With the decrease of photovoltaic cells price, SAUREA photovoltaic motors could be more affordable and reliable than conventional systems and therefore particularly well suited for off-grid applications. The concept has been patented (5 patents belong to SAUREA).

Description

The SAUREA photovoltaic motor is an electric motor using photovoltaic (PV) cells optically commutated by a shutter driven by the motor rotor to convert light energy into mechanical energy, without the need of any brushes or other power electronics. There have been developed electric motors driven by light through photovoltaic cells. But, the prior art motors required brushes or DC/AC converters. 

The purpose is to introduce another family of conversion system : photovoltaic motors. We underline here that such motors have been patented so far, but scientific literature on the topic is limited. The attempt is to fill the gap. A. PV cells + DC motor Light energy can be converted into mechanical energy by first converting light energy to DC electric energy using photovoltaic cells, and then converting this DC electric energy to mechanical energy using a DC motor [1]. This system is simple, but the DC motor requires brushes which must be replaced periodically. This is an important drawback for applications with reliability and maintenance constraints, like water pumping in isolated areas. B. PV cells + power electronics + AC (brushless) motor Light energy can be converted into mechanical energy by first converting light energy to DC electric energy using photovoltaic cells, then converting this DC electric energy to AC electric energy using DC/AC converter, and then converting this AC electric energy to mechanical energy using an AC motor [2]. Thanks to its DC/AC converter, the system can track the maximum power point of the PV cells, and operate efficiently the AC motor. But converters tend to be expensive, bulky and can have reliability problems in harsh environment. C. PV cells + AC motor = Photovoltaic motor Light energy can be converted into mechanical energy by first converting light energy to AC electric energy using photovoltaic cells commutated by a shutter mechanically connected to the rotor, and then converting this AC electric energy to mechanical energy using an AC motor. The system {commutated PV cells + AC motor} is called a photovoltaic motor. PV motors potentially entail low OPEX and CAPEX, because they require no brush or DC/AC converter. In addition, the low utilization factor of the PV cells (see section III) could be overcompensated by the rapid decrease of PV cells prices. On the other hand, the absence of converter and the use of a rotating shutter introduce new constraints that could limit the performances of the system. D. Potential applications PV motors are envisioned to be used in fully autonomous applications where reliability is a major constraint. One of such application is water pumping in isolated area. PV motors can be used as autonomous motor pumps to pump water from a well, to irrigate crops, or to store water in a tank. For water pumping application, an output power of 100 to 200 W is required. Coupled with blades, PV motors can be used as fans. It can be fixed to the roof of a greenhouse or housing, and drive the fan inside when sun shines. For ventilation application, an output power of about50 W is required. Other possible applications include fan-cooled parasols, solar water-heaters, mills, toys and advertising items. The SAUREA solar motor is the fist solar motor in the World which provide an energy that replaces the force of a man or a woman with 20 years maintenance free . Low Environmental Impact : The SAUREA solar engine provides mechanical energy over the sun. In this, it is comparable to a wind turbine operating in the wind. Photovoltaic energy has well-identified assets : - Sun is a renewable energy, inexhaustible and widely distributed on the planet, - Photovoltaic cells, Silicon, abundant material of the earth's crust, - Lifetime of photovoltaic modules is high > 25 years, - Production of solar energy, without movement, without noise, and without smell, substitutes for the production of electricity (fossil energy ...) and thus contributes to the preservation of the natural resources, the protection of the environment by the low levels of toxic waste, protecting the ozone layer by drastically reducing the production of greenhouse gases - All the components were chosen to be recyclable - NO waste provided - NO Battery - NO electronic Hight Social Impact : Human people : Reliable access to water, improves hygiene, Improves the bolus Society: Gives access to water, reduces inequalities, decentralizes the network, fixes the population, empowers and empowers women, educates children Economy: reduces energy bills, creates jobs for women, develops jobs in water management committees Low Environmental Impact : The SAUREA solar engine provides mechanical energy over the sun.

Focus on an application (first market B to B, for off-grid sites, rural villages...) : Water Pumping > A global report : 263 million people live more than 30 minutes from the first accessible water point and we note that women are mainly responsible for this task and according to the "World Health Organization" the WHO, the water source must be located within 1km of the focus and water supply time should not exceed 30mn. In spite of several years of development aid and thousands of community water access projects, ensuring universal access remains one of the major challenges for the development of emerging countries. That is an international market with 663 million people without access to water and mostly in rural areas, isolated sites (Off-Grid rural village). The problem : For years, the strategy has been to install pumps in severe weather conditions without maintenance: conventional photovoltaic pumping systems and manual pumps called PMH (pump with human motive power) whose mechanical and electrical components are considered little reliable then completely failing. Motor pumps require regular checks to prevent breakdowns. These can be done by a local technician trained to this mission. Faults on solar panels are relatively rare. Connectivity is however much more sensitive to high temperatures. Inverters are the most fragile part of the solar energy device. They are generally replaced after 5 years of use or even after 3 years for some. Resolution of problem : The self-commutated photovoltaic motor (MPA) produced by SAUREA overcomes these disadvantages in that it does not involve any switching, mechanical or electronic. This motor consists essentially of a solar panel in the form of a ring whose cells cyclically distribute the current in the coils of an engine through a shutter-perforated openings-integral with the motor shaft. Manufactured industrially, the cell ring has the same life as a conventional solar panel. For the rest of the constituents of the engine, everything is calculated and dimensioned to have a lifespan equal to that of the solar panel is to say 20 years without loss of performance and without any maintenance. The SAUREA engine can motorize volumetric, centrifugal pumps ... with durability of use and access to water for the end user. Our main competitors : SAUREA motor is the firs solar motor in the World because of a disruptive technology protected by 5 patents properties of SAUREA > no direct competitors.
