Rooftop systems on private new buildings have potential for 12 gigawatts by 2038

According to a recent study by Eon and Energy Brainpool, Germany has the potential to add up to 12 gigawatts (GW) of solar power capacity by 2038 if photovoltaic systems are installed on every newly constructed single-family, semi-detached, and terraced house.

The analysis projects that these new systems could generate approximately 87 terawatt hours (TWh) of solar electricity over the next 15 years, significantly contributing to Germany's climate goals by potentially avoiding nearly 45 million tons of CO2 emissions.

Philipp Klenner, responsible for customer solutions at Eon Germany, emphasized the importance of harnessing both existing and new building potentials for solar energy expansion. “As our calculations show, in addition to existing buildings, the potential of new buildings also plays an important role in solar expansion and climate protection. Germany should make use of this,” he stated.

While some federal states have already implemented mandates for photovoltaic installations on commercial and private rooftops of new buildings, there is no current nationwide requirement for such installations. The study underscores the significant impact that leveraging new construction for solar power could have on Germany’s renewable energy goals and overall climate strategy.
