RESIDENTIAL PV: INTERSOLAR/EES 2016 correspond with the expansion of renewable energy. In Switzerland Sonnen recently partnered Swisscom Energy Solutions in a pilot study. Swisscom Energy Solutions runs the Tiko network, which forms part of Europe’s largest smart grid. The network, which includes over 4,500 participants, links up the heating systems of residential customers to a smart storage network and provides Swissgrid, the transmission system operator with energy balancing services.

Mercedes-Benz
At Intersolar last year, Daimler unveiled its Mercedes-Benz labelled energy storage system, exploiting the car brand’s global reputation for quality, luxury and premium pricing in new stationary storage markets. The same proven battery technology that goes into Mercedes-Benz electric vehicles, made by Daimler subsidiary Accumotive, is also used to produce the company’s stationary storage systems, which are replete with the three-pointed star. Daimler began sales of the system in April, launching its new subsidiary Mercedes-Benz Energy Storage in June. Target markets include the UK, Netherlands and the US at some point, where the batteries, which can be scaled from 2.5kWh up to 20kWh can power electricity hungry air conditioning units and provide back-up power. The systems are compatible with SMA inverters. Mercedes-Benz Energy Storage’s solar partners span large, established European businesses, including Krannich, Bayware and Segen, one of the UK’s biggest distributors. Since 2015, Mercedes-Benz Energy Storage has also been working with partners to supply industrial gridscale projects in Germany, which will total 29MWh, providing services to Germany’s primary power market, when fully connected.

Aside from the domestic players, including Sonnen, Solarworld, Varta, E3DC and Senec, Germany’s residential solar plus storage market is competitive and large enough to attract international players, especially those that can sustain aggressive pricing. According to KfW, which has produced market data on the market share of KfW-supported by PV plus storage systems by manufacturer, South Korean electronics brands LG
