Our priority: To remain at the cutting edge of solar technology

At the cutting edge of solar technology Rester à l’avant-garde de la filière solaire

Through our SunPower affiliate, we currently offer our customers the most efficient and reliable solar panels on the market. We continue to invest in R&D to maintain our technological edge and to help build a competitive solar industry.

The world’s most efficient solar panels

With an efficiency percentage of 22.8%, SunPower solar panels are the most efficient in the world. Our panels leverage SunPower Maxeon™ cells to convert sunlight into energy more efficiently than conventional panels. In addition, they are more resistant to wear, corrosion and temperature fluctuations.

The result is 44% more efficiency, even on overcast days.

Developing increasingly competitive photovoltaic solutions

In the solar industry, our R&D efforts primarily aim to optimize cells, the key link in the photovoltaic value chain. We also work to reduce production costs and develop new applications and methods for storing photovoltaic solar energy.

To carry out our research, we draw on our full range of expertise and collaborate with major scientific organizations. We have signed partnerships with a number of globally recognized research centers, including:

  • MIT: The research program led with this school works to develop low-cost, long-life batteries suited to storing electricity generated by solar panels and other systems;
  • Institut Photovoltaïque d’Île-de-France (Ile-de-France Photovoltaic Institute or IPVF): One of the world’s largest research centers, IPVF collaborates with us on developing breakthrough technologies to make photovoltaic modules more efficient and less costly;
  • imec in Belgium: We work with this research center to develop more efficient structures and assembly processes for solar cells;
  • Laboratoire de physique des interfaces et des couches minces (Thin-Film Physics and Technology Research Center or LPICM): We formed a joint team with this research lab led by the French National Scientific Research Center and the École Polytechnique to integrate thin-film technologies in crystalline silicon and produce more reliable solar modules.


In partnership with MIT, we develop solutions for storing solar energy

We develop solutions for storing solar energy

Solar energy is an intermittent resource. Its availability varies considerably and there is no effective way to control or adjust demand. As a result, efficient storage solutions are needed to make the best use of this energy source.

Since 2009, we have worked with the prestigious Massachussetts Institute of Technology (MIT): to develop a high-capacity battery, notably capable of supplying energy throughout the night. In late 2010, this project’s encouraging results prompted us to establish a new startup: LMB Corp (Liquid Metal Battery Corporation), now known as AMBRI. The company’s mission is to develop high-capacity storage systems offering long battery life at a competitive cost.
