REGlobal’s Views: Solar installations have been on the rise when compared to wind in Germany, enabled by supportive policies as well as increasing affordability of solar. While wind turbine installations face local resistance in many areas, solar power is comparatively easier to install especially on on rooftops and balconies. In fact, the country witnessed a higher capacity addition in rooftop solar when compared to ground-mounted in early 2025.
