A new study has revealed that Norway’s buildings could generate enough solar energy to meet nearly half of the country’s annual electricity demand. With up to 87 gigawatts of technical capacity identified across rooftops and facades, the research highlights the vast potential of urban solar power in a nation better known for its hydropower and long, dark winters. Surprisingly, Norway’s high latitude offers unique advantages for solar generation, including long summer days, reflective snow, and cool temperatures that enhance panel efficiency, particularly for vertical installations on building facades.

However, the study also uncovers a critical limitation: the national grid can only absorb around 36% of this potential—roughly 31 GW—without risking overproduction during peak daylight hours. Beyond this threshold, surplus energy would need to be stored, exported, or curtailed, underscoring the urgent need for smarter energy management systems, battery storage, and grid upgrades. The findings suggest that while the technical promise of solar energy in Norway is substantial, achieving it will require coordinated investment in infrastructure and policy.

The report positions solar energy not just as a complementary force to Norway’s hydropower dominance, but as a key player in the country’s broader climate strategy. With thoughtful planning and modernisation, Norway could transform its urban landscape into a decentralised, low-carbon power network—one that empowers citizens, reduces emissions, and sets a precedent for high-latitude nations worldwide.
