BSW-Solar: In 2020 photovoltaic memory increased by 47 percent

The interest in photovoltaic storage solutions is unbroken.As the Federal Association of Solar Economics (BSW-Solar) reports, demand has increased by 47 percent in 2020.The number of solar power stores in the third year in a row grew by around 50 percent.The market had benefited from the fact that twice as many photovoltaic systems were installed on their own homes as in the previous year-and around every second homeowner combined its new facility with a memory.The BSW solar estimates that around 88 in Germany in 2020.000 new home memory were installed.Overall, the stock has been around 270.000 photovoltaic memory increased.

Almost 80 were made in the market master data register for 2020.000 battery storage new installations with a capacity of around 775 megawatt hours and an output of 475 megawatts registered.At the end of 2020 there were around 175.000 battery storage with a cumulative capacity of 1.950 megawatt hours and a performance of 1.400 megawatts registered in the Federal Network Agency database, which has been online for two years.Only storage systems in operation with fully registered performance, capacity and battery technology are recorded - without these filters the number is still a few thousand entries higher.

The BSW solar expects the memory question to be further attracted.This is in addition to the energy policy necessity of sunken prices, growing climate protection sensitization and an increased need for independence from consumers.The industry association points out that the current battery storage capacity for the implementation of the climate goals, to ensure needs-based provision of green electricity and for the compensation of short-term weather and time-related generation fluctuations in the solar and wind energy are almost dilapidated by 2030 according to calculations by market researchers:From currently 2.4 to around 18 gigawatt hours.As a result, the annual market for inpatient battery storage will double by 2025, probably even stale until the end of the decade.

The BSW-Solar also explains the increasing interest on the part of companies with the fact that due to the EEG amendment, three times more solar power has been used since the beginning of the year, without system operators having to pay an EEG surcharge for this.This also simplifies the storage equipment for solar power systems that fall from EEG funding after 20 years.For operators of these agreed plants, it is the most economical to consume as many kilowatt hours of their copied solar power systems as possible, according to BSW general manager Carsten Körnig.In order to further accelerate the storage of storage, further legal reforms are necessary, including a reduction in the double pollution of one-off and re-saved network current of prosumers with fees, levies and levies.
