flag Norwegian study finds rooftops can generate 20% of country’s electricity, guiding solar expansion.

flag A Norwegian research team has mapped rooftop solar potential across the country, finding it could generate up to 30 terawatt-hours annually—about 20% of current electricity demand. flag Coastal areas like Oslofjord and Sørland show the highest potential, with Oslo’s rooftops capable of producing 8.2 TWh, matching Berlin’s output. flag The study, part of the SunPoint project, assessed roof orientation, tilt, and obstructions to guide solar deployment. flag Norway added 49 MW of solar capacity in early 2025, bringing total capacity to 763 MW, including the world’s largest vertical rooftop installation in Tromsø. flag Researchers say rooftop solar is vital to meeting national targets while protecting natural landscapes.
