Photovoltaic systems, electric cars and home electricity storage systems complement each other perfectly. Solarwatt from Dresden has perfected the system together with BMW. As part of its immediate climate protection program, the federal government is considering introducing a requirement for solar roofs on new private and commercial buildings in Germany. Especially since the electricity demand will grow strongly in the coming years due to the increasing number of electric cars.
Solarwatt, manufacturer of PV modules and storage batteries from Dresden, presented the new generation of modular home electricity storage, which was created in two years of development work and cooperation with BMW. The electricity storage device called "Battery Flex AC-1", which in its smallest size has a capacity of 4.8-kilowatt-hours and an output of 1.5 kilowatts, uses new cells from the Chinese manufacturer CATL. The accumulators are installed by the Webasto automotive supplier.
At the Schierling plant, Webasto produces the cell modules for the new electricity storage systems that Solarwatt has developed together with BMW. BMW buys lithium-ion cells for this from the Chinese manufacturer CATL. Solarwatt has been working on photovoltaics systems for ten years.
