Solar-PV magazine reports that the package will rely on Sonnen’s MyPower battery solution.
“The French storage market is at the very beginning and therefore offers enormous potential. This shows that more and more people around the world want to shape their energy future themselves and to use our technology,” said Sonnen CEO, Christoph Ostermann.
“This solar battery with a designer look, is flexible with made-to-measure storage of between 2.5 and 15 kWh. It means that a self-sufficiency rate as high as 96 per cent can be reached in certain configurations. Sonnen is installed in more than 30,000 homes worldwide,” Engie noted.
Power prices have risen by around 20 per cent over the past years, and that an interesting incentive scheme is currently open to solar PV projects for self-consumption.
According to their joint press release, Engie is currently providing power from clean energy sources to around 1.6 million customers in France.
The company is also active in the residential PV segment through Netherlands-based Sungevity International, the European unit of U.S. residential solar company, Sungevity, which it acquired last year.
Sonnen, a venture capital-backed start-up, said the package, called “My Power”, would be available immediately.
Herve-Matthieu Ricour, head of Engie’s French retail unit, said in Paris the utility estimated there were about three million power customers in France with detached houses that are suitable for the solar and storage package.
In the south of France, users could cover nearly 100 percent of their power needs between May and September with the package, he said, while in the north customers would be able to generate about two thirds of their electricity needs.
Sonnen’s Chief Executive Christoph Ostermann told Reuters in Germany that the company hoped to replicate inroads in the German and Italian markets, helped by France’s goal to reduce its reliance on nuclear energy and the dominant position of former monopoly EDF.
