Inventing Your Solutions
Wysips® Glass Serving Agriculture

Putting solar energy to work for farmers, so they can grow greenhouse crops that are more profitable, more ecological, and more reliable at all latitudes: this is the goal of Sunpartner Technologies’ R&D, in partnership with the French National Institute For Agricultural Research (INRA). With the continuous expansion of acreage cultivated under glasshouses throughout the world (+10% per year, according to the International Society for Horticultural Science), environmentally responsible greenhouses are a crucial factor in energy transition, nutrition and sustainable development for farmers, for land planners, and for all people.


Our R&D provides practical solutions for the business and energy concerns of our clients. Our process advances either by technology breakthroughs: since they outperform existing technologies, our solutions place our clients light years ahead of their competitors; or by disruptive innovation: by completely redefining the rules of the game in a new way from existing technology, our solutions create the strategic markets of tomorrow.

Sunpartner Technologies is involved in two revolutionary R & D projects: smart textiles and solar greenhouses.

Photovoltaic Textiles – SOL-TEX: Fabrics of the Future

> Objective
Make a photovoltaic thread that, whether woven or knitted, will be integrated into the fabric substrate to make a smart textile that can generate solar electricity. This invisible technology will enable the textile to retain all its usual properties (texture, color, suppleness, lightness, strength) while making it energy independent, able to power a variety of smart functions and other nearby devices.
> Applications, Markets
Awnings and covers (motorized or not), agricultural protection nets, sheeting for greenhouses, protective clothing, accessories in the passenger compartment of vehicles, sport and recreation equipment.
> Technology
The SOL-TEX project is working on integrating PV cells into the structure of the fabric substrate itself. Part of the research is developing a thread with a PV cell made from inorganic material, while another part involves inventing a solution for recovering-converting energy, which can be integrated into end products that are already on the market.
> When
This technology is expected to reach the market in 2019.
The project milestones:
>2015: Samples of PV threads
>2016: First textile samples
>2018: Samples of industrially manufactured textiles
>2019: Product prototypes
> Who
Launched in February 2014, Sunpartner Technologies is managing this project with partners:
5 Companies
Sunpartner Technologies, specialist in solar NETs (inventor of Wysips® technologies)
Qualiflow Therm, specialist in manufacturing equipment for the microelectronics and photovoltaic industries
Groupe Payen, leader in polymer fibers, threads, and elastic fabrics
Texinov, manufacturer of knitted technical textiles
Raidlight Vertical, the leading brand in trail-running equipment
GreenSysTech, integration of energy management solutions (subcontractor)
Leyton, administrative and financial management
1 Research Institute:
CEA-Liten (Laboratory for Innovation in New Energy Technologies and Nanomaterials).
Soltex is supported by Bpifrance and has been certified by the CapEnergies competitive cluster.
A User’s Club enables us to anticipate the needs of manufactuers and end users in order to prepare the commercial launch of this technology.

Solar Greenhouses – Purple Sun: The Future of the Microalgae Industry

> Objective
Accelerate the development and performance of the microalgae industry with a solar greenhouse solution that optimizes both the production of algal biomass and photovoltaic energy.
> Applications, Markets
Microalgae is used for animal feed, cosmetics, and pharmaceuticals and is a key factor in the development of green chemistry (fertilizers, bioplastics) and bioenergy.
> Technology
Purple Sun is a revolutionary concept for positive energy microalgae culture. The project segments the solar spectrum to promote both biomass photosynthesis and the generation of photovoltaic electricity. In doing so, Purple Sun is also creating the next generation of PV greenhouse components.
> When
Purple Sun has been awarded the French Research Ministry’s ANR research grant, in Bio-Materials and Energy 2013-2016.
> Who
The Purple Sun consortium is made up of six partners:
ARMINES PERSEE (Mines Paris Tech),
lNRA Sophia-Antipolis (team TEAPA),
INRIA Sophia Antipolis-Méditerranée (team Biocore), project leader,
LOV (Laboratoire d’Océanographie de Villefranche, CNRS),
Sunpartner Technologies.
