German solar demonstrated just what it is capable of in the first two weeks of June,” says Tobias Rothacher, expert for renewable energies at Germany Trade & Invest, the country’s economic development agency.
The latest analysis from the Fraunhofer ISE solar energy research institute shows that photovoltaic systems generated a record 24.24 GW between 1 and 2 pm on Friday, June 6 and a total of 1.26 TWh over the entire week.
On June 9, which was a national holiday in Germany, solar power production peaked at 23.1 GW, which equaled 50.6 percent of total electricity demand – setting another milestone.
“The large amounts of solar electricity being generated demonstrate clearly that Germany will need more energy storage capacity in the future. Already, the more than 1.4 million photovoltaic systems are producing a surplus, especially on sunny days around midday,” Rothacher says.
“From now on, every new solar system that is installed in Germany increases the need for electricity storage solutions. The cost of storage systems is forecast to drop in the coming years and this means that storage is not only becoming more necessary – it is becoming more attractive from a financial point of view as well.”
