Ragde Eiendom, REMA 1000 and Sunday Power are now rolling out solar power systems on retail buildings across the country. The new installations improve the energy rating of every building that receives solar panels, while also increasing property value, according to the latest analyses from Newsec.

Sunday Power installs solar power systems on store rooftops, generating cost-efficient and renewable electricity. Most of the energy is consumed directly in the stores, while the buildings benefit from an improved energy profile – strengthening both their attractiveness and market value. Sunday Power manages project execution and system operations, while NTE owns the installations. The delivery is carried out in close collaboration with property owner Ragde Eiendom and Bergen Synergy, REMA 1000’s main electricity supplier in Norway.
As part of a larger initiative between Ragde Eiendom and Sunday Power, covering more than 25 buildings in total, solar power will be installed on over 10 REMA 1000 stores. The goal is to complete phase 1 during 2025.

The first system was commissioned at REMA 1000 Siljan, which now has a solar power installation with a capacity of 97 kWp. Most of the production is used directly by the store, and the building’s energy rating improved from B to the top rating A.
REMA 1000 has a clear ambition to increase its share of renewable energy.
“We are very pleased that the property owner is making our stores more environmentally friendly. In this project, we are replacing part of our electricity consumption with solar energy produced directly on the rooftop, which also helps relieve pressure on an increasingly strained power grid. REMA 1000 works every day to operate efficiently, affordably, and responsibly, and here we have strong partners who help us achieve exactly that,” says Geir Bastiansen, Technical Director at REMA 1000 Norway.
He explains that they have tested solar power and see strong value in a comprehensive, sustainable solution, including operations managed by Sunday Power.
“This allows our store managers to focus on what they do best – running the store,” he adds.
Ragde Eiendom has long worked with solar power to strengthen the energy profile of its property portfolio and make smarter use of its building stock.
“By installing solar power on our rooftops, we contribute to more environmentally friendly energy use in our buildings. This is a concrete measure that delivers long-term impact,” says Lars Åmellem, Business Developer at Ragde Eiendom.
Historically, the largest commercial buildings have delivered the strongest profitability for solar investments.
“With a more standardized and integrated model, we can now achieve profitable solar installations across a larger share of our portfolio, including smaller commercial buildings. Developing rooftop solar can be a relatively complex process, involving coordination between energy advisors, structural engineers, and EPC contractors, securing energy agreements, and then operating these installations with minimal downtime for decades. In collaboration with Sunday Power, REMA 1000 Norway, and Bergen Synergy, we have developed an efficient and standardized end-to-end solution that can be applied to all types of properties and enables simple rollout across a larger portfolio,” says Åmellem.

The collaboration also demonstrates how solar power can increase property value.
“Analyses from firms such as Newsec, DNB Næringsmegling, JLL, and Colliers show that energy-efficient buildings have higher value, lower risk, and better financing terms,” says Rikard af Ekenstam, Chief Commercial Officer at Sunday Power.
A 2024 study by Newsec shows that upgrading a building from the lowest energy ratings (F–G) to A or B results in an average value increase of as much as 15 percent. The analysis included 1,000 buildings in Sweden, of which 670 were commercial properties.
According to the study, buildings with an energy rating of C are valued on average 7 percent higher, while D–E ratings command a 5 percent premium compared to the F–G reference category.
“It is exciting to work with forward-leaning partners like Ragde and REMA 1000, who create value from rooftops that would otherwise remain unused. This project also pushes the boundaries of what is economically viable for smaller commercial buildings within our platform,” af Ekenstam concludes.
