E.ON is developing an energy storage system in partnership with German company Solarwatt.

Munich-headquartered E.ON said today that the first models of the domestic system designed to store electricity from rooftop solar panels will be rolled out in a few months.EON partners with Solarwatt on energy storage

E.ON said the potential for electricity storage devices in Germany “is enormous. In just a few years nearly 100 per cent of solar arrays may be sold with a storage device. In addition, the country’s more than 1.5 million existing solar arrays offer huge potential for retrofitting with storage devices.”

The deal with Dresden-based Solarwatt is the first step in what E.ON board member Bernhard Reutersberg said was a plan “to become a leading provider of electricity storage systems in Germany”.
