Germany’s market for solar energy and home storage systems will collapse if the government doesn’t deliver on its promise to remove the existing cap for support payments, according to market research company EuPD Research, reports Petra Hannen in pv magazine.

If feed-in tariffs are stopped when Germany’s solar capacity reaches 52 gigawatts (GW), investments in small photovoltaic installations and home storage systems will total 450 million euro in 2021, compared to a base scenario without cap of 1.4 billion euro, the researchers forecast, according to CLEW.

They said that several projects will not be built at all with the cap in place, and many others will be cut in size to achieve a higher own consumption and minimise feeding power into the grid.
