Are all regions in Germany suitable for rooftop photovoltaics?
Household rooftop photovoltaics, which accounted for more than half of all systems installed in Germany in 2023, play an important role here. But not all regions in Germany are equally suitable for their installation. The purpose of this study is to identify regions which still have a particularly high potential for new installations.
How many homes in Germany have a photovoltaic system?
More and more households in Germany have already installed photovoltaics in recent years. By the end of 2023, one in eight residential buildings with one or two apartments had a photovoltaic system installed. Most installations are located in the south of Germany, where some regions already boast one in five dwellings with photovoltaics.
How many photovoltaic systems are there in Berlin?
Compared to solar thermal energy, there are far more photovoltaic systems registered in Berlin. As of July 7, 2023, 20,985 systems were in place, with a total installed capacity of around 230 MWp.
Why are rooftop photovoltaics important in Germany?
The German Federal Government wants to further increase the expansion of photovoltaics (PV). From the year 2026, new capacity installations are to triple from current levels.1 In order to reach this goal, rooftop photovoltaics installed by private households play an important role, partly because these roofs would otherwise remain unused.
How many solar panels are installed on a house in Germany?
Especially in the eastern part of Germany rooftops of single and two-family houses are in many cases not yet utilized for PV installations. By the end of 2020, around 1.3 million photovoltaic systems were installed on one- and two-family houses in Germany. An analysis by EUPD Research confirms an overall saturation of eleven percent.
Are solar panels mandatory in Berlin?
The set of measures stipulated in the master plan is accompanied by the Berlin solar law. Solar panels have been mandatory since January 1, 2023. The installation and operation of photovoltaic systems have been mandatory since then for new and existing buildings under certain conditions (SenK 2021).
