Listen to the article: The summer 2021 was gray and rainy, but the expansion of solar energy has not done any harm. In the next few years it should go even faster, argues the industry association BSW. Munich (dpa) - The solar industry expects the expansion of solar energy in Germany to accelerate further in the next few years. This year, the installed capacity of photovoltaic systems around estimated 10 to 15 percent rise - that would be around five gigawatts, as the German Solar Industry Association (BSW) announced on Wednesday. In order to achieve the climate targets raised by the outgoing black-red coalition shortly before the general election, it would be more than tripling the annual expansion to 15 to 16 gigawatts necessary, said BSW managing director Carsten K\u00f6rnig in Munich. According to BSW, there are currently around 4.5 million solar systems in operation for generating electricity or heat. According to the industry association, a driver of the expansion in the next few years will be the increasing spread of electric cars and the associated electricity demand. "For 2030 we expect around ten million electric cars," said K\u00f6rnig. "Surveys repeatedly show that just under 30 percent of e-car owners charge their vehicles at home." According to BSW estimates, ten million e-cars would have a requirement of 30. 000 Gigawatt hours of charging current mean. Homeowners have invested heavily in solar energy in recent years, but they do The demand from companies and businesses for solar systems has fallen, as K\u00f6rnig said. The BSW managing director blamed unattractive funding and framework conditions for this. According to this, private operators of smaller solar systems do not have to pay an EEG surcharge, but commercial enterprises do Grainy. According to the BSW managing director, a much faster expansion of solar energy cannot be achieved without a larger participation of companies. \u201cThis is not only possible with solar parks and with private homes.\u201d The association therefore demanded an \u201cacceleration law\u201d for solar energy from the future federal government. First and foremost should be higher expansion targets for photovoltaics.
