One analyst has predicted that 12,500 residential PV storage systems could be installed in Germany in 2015, more than the total number of systems installed with support from a government scheme in its first two years.

This month marks the second anniversary of the introduction of Germany’s financial support measures for battery-based energy storage systems. These include a federal ministry of economics and technology (BMWi) grant of around €600 per kilowatt of PV installed for new projects, or slightly more in the case of retrofitting battery storage to an existing PV installation. The remainder of the support comes in the form of low cost loans from Germany’s development bank, KfW.

KfW announced this week that in the two years since the scheme was launched in May 2013, it has given out loans for the installation of just over 10,000 systems. This was done at a cost of about €163 million, the bank said. This compares favourably with the first year of the scheme, during which about 4,000 systems were installed.

Markus Hoehner, head of EUPD Research, welcomed the news and told PV Tech Storage that his firm expected the growth to continue on an upward trend. Hoehner said the figures given by KfW tallied with EUPD’s findings to date.

“For 2015 we estimate 12,500 new systems will be installed – with and without KfW support,” Hoehner said.
