The research outfit EuPD, has led a study which has predicted a nationwide market of 100,000 units by 2018, up from 6,000 in 2013, citing falling PV prices as the “most significant reason” for this “monumental” commercial growth. The study was commissioned by the investment body Germany Trade & Invest (GTI).
Germany’s “energiewende” has been a big contributor to the 80 percent fall in the price of solar modules, and the government is now looking at ways to bring down the costs of the next piece in the puzzle of its renewable energy transition – battery storage.
During the first half of 2013, “energiewende” kicked off a program to finance the mass introduction of battery storage into homes and small businesses – a move which it has described as absolutely essential for the European region to successfully achieve, and move beyond, 40 percent of the market being penetrated by renewable energy.
The first six months of the program were very promising, over 1,900 homes and small businesses had registered for government loans and grants which would facilitate the installation of battery storage in conjunction with solar systems in their homes. By November, approximately €32 million in loans have been allocated and €5 million in grants, and of those about ten percent of the allocated sums were in the initial phase of the program.
Earlier this month, another EuPD report found that less than one-third of German PV installers are now offering energy storage options to their customers, with British and Italian counterparts to follow suit.
The study also found that Germany has the biggest uptake of household energy storage systems due to the fact that a percentage of storage system costs were paid as a direct subsidy to consumers.
Tobais Rorhacher, senior manager for renewable energies at GTI said “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.”
He added, ““Most of these systems will still produce electricity even after their 20 year feed-in tariff period.”
