2A study commissioned by the Federal Association of the New Energy Industry (bne) comes to the conclusion that solar parks have a positive effect on biodiversity.

The aim of the study was to show whether and to what extent solar parks can contribute to floristic and faunal biodiversity.

For this purpose, documents on the vegetation and fauna of 75 solar parks in Germany were evaluated. However, the studies and investigations available for the parks, which are spread across 9 federal states, were mostly carried out during the parks' approval phases and are very heterogeneous. Nevertheless, documents from almost 40% of the solar parks eligible for the assessment could be used. Intensive studies are also available for some parks, some comparing the federal states before and after, so that meaningful conclusions can be drawn. From this it can be deduced that solar parks generally have a positive effect on biodiversity and which structures can contribute to increasing biodiversity, especially with regard to the distance between the rows of modules and maintaining the distances between the rows.

In addition to an evaluation of the corresponding documentation with regard to the characteristics of the vegetation and the settlement of the parks with different animal groups, this study describes some parks in more detail as examples. Finally, information is provided about the content, structure and scope of future monitoring studies. One goal of such monitoring could be to develop uniform minimum standards for the construction of solar parks in the medium term.

The most important results of the evaluation of the available documents are:
