A Norwegian research team has published the first full solar card from Norway, which calculates that the implementation of solar cells on top of existing roofs can generate up to 20% of the current electricity needs of the country.
Solar on the roof can theoretically cover a maximum of 20% NorwayThe current electricity needs, according to research.
A Norwegian research paper Has the first full full solar card. The map was developed via the Sunpoint project, a collaboration between the Norwegian Meteorological Institute and the Institute of Energy Technology (IFE).
The calculations of IFE van Zonne energy potential on existing roofs took into account both the angle and the direction of the direction, as well as existing structures on the roofs such as chimneys.
The research showed that Norway could produce 30 TWH van Zonne energy by adding solar energy to the roofs of existing buildings. According to figures published by Statistics Norway, the total electricity production in the country reached 157.2 TWH in 2024.
The best conditions for solar energy in Norway were identified in coastal areas, in particular in the outer Oslofjord and along the coast of Sørland. Berg -like regions of South Noornwegen also appeared to have a high solar radiation, but were identified as unrealistic for solar installations.
The research by IFE showed that the energy produced on a tanning factory on a roof in Oslo, the capital of Norway, is comparable to that of a factory in the capital of Germany, Berlin. The map calculates 8.2 TWH of electricity can be generated by installing solar energy on all roofs of Oslo, equal to 14% of the city’s electricity consumption.
In the southeastern city of Fredrikstad, close to the border with Sweden, Zonne -Zonne -Zon -Zon could generate 1.1 TWH energy, equal to 24% of the total electricity consumption. In the neighboring city of Tønsberg Solar, 0.7 TWH can generate electricity, equal to 26% of the total electricity consumption.
“Although the figures are based on technical potential, this clearly shows how large role solar energy can play in tomorrow’s energy system,” said IFE researcher Stine Fleischer Myhre.
Myhre added that solar energy will be a key factor in achieving the goal of Norway to generate 8 TWH solar energy. “By using the use of already developed areas, we can also limit the need to develop in untouched nature,” she said. “Now we hope that the map makes it easier for public and private sectors to make informed choices about where it is worth installing solar cells.”
Norway deployed 49 MW From solar energy during the first half of 2025, which takes cumulative capacity to 763 MW.
In September, the The world’s largest To date, vertical solar installation on the roof in the Norwegian city of Tromsø has been used in the Norwegian city.
