Germany 'set for PV storage boom'

Storage for domestic solar is set to rocket in Germany

Sales of residential solar power storage systems in Germany are expected to rocket by almost 20-fold in the next four years, according to new figures.

A study commissioned by inward investment body Germany Trade & Invest (GTI) from research outfit EuPD forecasts a market  of 100,000 units by 2018, up from 6,000 last year, with falling PV-generated electricity prices the “most significant reason” for this “monumental” commercial growth.

“A battery is the next logical investment for owners of solar power installations and whose systems are coming to the end of their 20 year contract lifetime,” said Tobias Rothacher, senior manager for renewable energies at GTI.

“Most of these systems will still produce electricity even after their 20 year feed-in tariff period. The system owner can then decide if he wants to waste this electricity or if he wants to use his low-price electricity rather for himself by installing a battery system. We believe most people will decide for the latter.”

GTI calculates there are some 1.4 million PV installations in Germany, over one million of which are privately owned.

The energy storage issue is an increasingly high-profile issue in Germany, as a partial solution to overbuilding expensive HVDC power transmission lines across the country.
