germany storageNew figures published by German solar lobby group BSW indicate that prices of solar power storage units are dropping considerably, and sales are picking up. Nonetheless, the market remains quite small.

Only recently, I wrote about how the German PV market continues to slow down, although solar power is now much cheaper than electricity from the grid (socket parity). My main conclusion was that since Germany has a policy of direct consumption instead of net-metering, socket parity requires storage, and the additional cost of the battery system ruins the calculation.

Today, BSW published a press release explaining that the price of solar storage systems dropped by around a quarter over the last six months. More importantly, 32 percent more applications were submitted in Q3 than in Q2 2014 for the upfront bonuses that the KfW Bank provides for such investments. The bank, which funnels governmental incentives into the market, reimburses investors for up to 30 percent of the cost of the storage system and also provides low-interest loans for the array and the storage.

 If that trend continues, the market will truly be booming soon. But it starts off at quite a low level. The BSW puts the number of households with solar roofs and battery storage at just above 15,000 – out of more than 800,000 systems smaller than 25 kilowatts (source in German), equivalent to less than two percent of those systems.

    Could we have some information on size and cost of the systems being installed?

    What would be really great would be a multi-site database so that consumers could keep up with what is available in different countries.

      http://www.strom-speicher.org/stromspeicher-preise/ (June 2013)

      The header on that table reads:
      Hersteller (manufacturer)
      Produktname (product name)
      Technologie (technology)
      Wirkungsgrad (efficiency)
      Speicherkapazität (storage capacity)
      Entladungstiefe (depth of discharge)
      Zyklen (cycles)
      Peis in Euro (price in EUR)

      As for your wish for a database.. I’d say it’s way to hard for this atm as this will be very hard to maintain and keep recent..

      Btw, there is a conference/expo for energy storage in March 2015 in Dusseldorf (GER).. maybe Zach want’s to go as he’s relatively close?
