The increase in new installations was mainly due to a 40% drop in prices over the past three years. German solar association Bundesverbands Solarwirtschaft expects their number will double to 100,000 in 2018.

Currently, there are in Germany approximately 52,000 operational solar batteries.
Currently, there are in Germany approximately 52,000 operational solar batteries.

According to provisional figures provided by German solar energy association Bundesverbands Solarwirtschaft (BSW-Solar), there are now approximately 52,000 operational storage systems serving PV installations in Germany. This number corresponds to a capacity of approximately 300 MWh, a BSW spokesperson told pv magazine.

Last year, the association said, about 20,000 new storage systems were installed in the country. This growth was mainly attributable to an increasing demand for self-consumption, as well as to decreasing prices.

BSW-Solar finds that prices for solar storage systems in Germany dropped by around 40% over the past three years. The association, however, has not provided specific numbers about current market prices.

Furthermore, BSW-Solar reports that one out of two individuals who plan to install a residential PV system also intends to install a battery technology. The association added it remains quite optimistic about the future of solar+storage in Germany, and that an increase in demand for this technology over the next two years is very likely.

The association forecasts that in 2018 the number of installed solar storage systems in Germany could surpass 100,000.

    Average storage size 5.8kWh. Obviously they use another energy source for home heating. Gas? Electricity? Firewood?

      Germans mostly use natural gas for home heating, but also heat pumps and district heating. see this report https://www.bmwi-energiewende.de/EWD/Redaktion/EN/Newsletter/2015/09/Meldung/infografik-heizsysteme.html

      Solar panels in Germany are used for running electric appliances.

      I live in Sweden where central heating is a must due to cold winters. 50% of private homes have a ground source heat pump or air heat pump for the central heating and tap warm water. The other 50% of private homes are either attached to a district heating system or run their furnace on wood pellets. Heat oil was abondened many years ago, to expensive.

      In addition to the reply below, please consider that (in general) houses in Europe are highly efficient, at least the new ones. They are built with the aim to minimise heat dispersion both during winter and summer months, reducing the energy needed for heating and cooling and and hence the bill
      Something not too fancy or expensive, just well thought 🙂

      Definitely something we should do and request to be done also here in Australia

        What I am doing right now… and nobody understands it :))

          Good on you! Keep up and spread your experience, despite what others say.

          A better insulated house is also more comfortable not only temperature wise but also from a noise perspective, hence more healthy and enjoyable.

            In a hot climate you have to be very careful about insulating a house. If there is any ingress of sunlight through a wrongly placed window or door this can very quickly create a solar oven effect! You have to create an island of cold in a sea of hot. Hot sun, hot wind, hot ground. Heat emitting humans and appliances in the house. In this situation you either take advantage of the diurnal variation of the ambient air temperature by building large thermal mass into the walls and floor or you minimise the thermal mass with well insulated thin floor, walls and ceiling and use an air-conditioner to extract the heat. In Australia most houses are built with a thin internal envelop, mostly,but not always, insulated with either a silvered vapour barrier, a wall cavity or fibre batts. The floors of most modern suburban homes are concrete slabs plonked directly on the (carefully) prepared ground effectively creating a single thermal mass with the ground. The roofs often have a thin layer of fibre insulation backed with a silver vapour barrier directly under the roofing material. Not a great deal of effort is taken to ensure proper orientation of windows to avoid ingress of unwanted sunlight. There is usually not much attention given to shading or the catching of cooling breezes – just a dirty-great big air-con to substitute for any passiv-Haus design failings .

          Are luxury showers banned in Germany?

          Just goes to show that banning luxury showers and toilets is an extremely silly thing to do when the house is not insulated properly.

            I’ve seen that post before Brunel… It’s a bit repetitive, don’t you think? Could you link it better to this topic? Thanks. 🙂

            Are you MaxG.

          • David Jago 3 years ago

            LOL. No. What’s the thing about “luxury showers and toilets”?

            What’s a luxury shower and luxury toilet?

    • MaxG 3 years ago

      Usually gas or oil…

    • cleeee 3 years ago

      Heating is mostly done by natural gas or district heating (large conventional power plants produce massive amounts of heat and it’s used for heating). But the average power consumption per year in Germany is pretty good. A 4 person household in general needs about 3500 to 4000kWh. My family (4) is living in a small flat and we only use around 2800kWh per year…Modern houses are pretty energy efficient and many older ones are modernized to reduce the loss of heat. For example windows consist not only of one pane but mostly of two panes or even three for the most energy efficiency. Because heat is lost through windows very easy…But there’re many more things to save energy…But I would prefer a 14kWh battery storage from Tesla because then you can go most of the time fully off grid.

    The last house I built in Germany used 1/10 of the then normal energy usage. It was a 10 family unit, but with a domestic single household house heating system. We made the news, fighting the local gas company refusing to put a thinner gas pipe in (the normal domestic one), because the double sized pipe would have cost 10 times as much… the point: the energy companies in Germany were bastards too… 🙂

      Any articles online about your fight against big oil?

    That’s another way to get 100MW of electricity storage.
