April 1 (Renewables Now) - The German state of Baden-Wuerttemberg is introducing an obligation for the installation of solar photovoltaic (PV) systems on the roofs of all new residential buildings in the state in a bid to speed up the transition to green electricity.
The obligation will apply to new buildings whose application for a building permit or required documentation has been filed after May 1.
The installation of solar plants will become mandatory also for all fundamental roof renovations that will be started after January 1, 2023.
The changes to the existing regulations in this area have been approved by the state's cabinet and follow the introduction of mandatory solar roofs for all new non-residential buildings such as company roofs, open parking lots and halls as of January 1, 2022.
According to Baden-Wuerttemberg's statistics office, about 14,300 residential buildings were built annually between 2016 and 2020 and roughly 80% of the buildings are suitable for solar plants.
Until now, only 11% of the existing potential for rooftop solar systems in the western German state has been exploited.
