Kleve Excels in Implementing Photovoltaics on Public Buildings

An analysis by Viessmann Climate Solutions reveals that, alongside Kleve, Offenbach ranks highly among cities with 50,000 or more inhabitants for the number of photovoltaic systems installed on public buildings. Berlin leads overall based on the total number of these systems.

The analysis, which used data from the market master data register, compared the number of photovoltaic installations on public buildings to the total number of systems per city. Kleve tops the list with 4.7% of its solar systems installed on public buildings, followed closely by Offenbach at 4.6%. Other high-ranking cities include Böblingen and Tübingen in Baden-Württemberg with 4.0% and 3.5% respectively. Marburg also features prominently in the rankings.

Conversely, cities such as Bergisch Gladbach and Grevenbroich have much lower percentages, with only 0.2% of their solar systems on public buildings. Nordhorn also has a 0.2% share, despite having 3,600 total systems, with only nine on municipal buildings.

In larger cities with populations of 100,000 or more, Offenbach and Hanau achieve notable results with 3.1% and 3.1% respectively. Bremerhaven and Stuttgart follow with 2.9% each.

When considering absolute numbers, Berlin leads with 543 photovoltaic systems on public buildings, followed by Munich with 326 and Stuttgart with 253. At the other end of the spectrum, Görlitz in Saxony has only one system on a public facility, with Gera in Thuringia having just four.

Berlin also stands out at the federal state level, with 1.9% of its total solar systems installed on public buildings. Bremen and Hamburg follow with 1.7% and 1.5% respectively. Brandenburg has the lowest percentage with just 0.6% of its 102,500 photovoltaic systems on public buildings, with Saxony-Anhalt and Saxony slightly ahead at 0.7%.
