Installed rooftop PV system: -Can cover the entire building's power consumption

The modern commercial building of 5000 m2 in Røyken Næringspark outside Drammen has the capacity to store 20,000 sets of car tires. Going for solar cells in the new building was a strong desire from both farm owner Medvind Eiendom and tenant Bilia Norge AS.

Attractive to the tenant
The new tire hotel opened in December and offers storage of summer and winter tires, cleaning, checking pattern depth and air pressure. In addition, the modern tire hotel has a rim workshop and automatic storage and washing systems.

General Manager Geir Thomassen is very pleased with the new premises and the solar installation on the roof. “We are proud of our new building and the modern solutions we use here. Then it's extra fun to think that the deck hotel is powered by solar power.”

The substantial size of the plant allows them on sunny days to cover their entire electricity consumption in the building, and sell the surplus electricity to the grid.

Jon Ferdinand Finne, property manager at Bilia, is pleased that in cooperation with the building owner and Sunday Power they have achieved the solar installation on the building.

“With a solar installation of this size, we save over 122 tons of CO2 per year. This is an important climate measure for our business and is in line with our clear strategy of targeted work to increase sustainability”. The property manager adds that this is the fourth Bilia building with rooftop solar cells, with an installed power of 460 kWp.

Property manager at Bilia, Jon Ferdinand Finne shows off the new tyre scanner that automatically identifies damage in the tyre to Rikard af Ekenstam, CCO of Sunday Power.


Raising the value of the building

Medvind Eiendom takes its environmental responsibility seriously and places very high demands on the environment and the environment. All Medvind's buildings are climate certified and are in class “A”.

“Through our collaboration with Sunday Power, we have set a goal that all our buildings should have solar cells installed on the roof to reduce our climate footprint,” says Andreas Greve-Isdahl of Medvind Eiendom.

The Chief Commercial Officer of Sunday Power, Rikard af Ekenstam, commends both Medvind and Bilia for their focus on solar energy and climate action.

“It is a pleasure to work with players who are both leading the way as good examples in their industries. In addition to being the right thing to do with the roof of large, flat commercial buildings, we know that green buildings are also more attractive to tenants and are more valuable.”

Ekenstam refers to a survey recently conducted by Newsec. The results showed that green commercial buildings can get 20-30 basis points lower yield.

“Now we are looking forward to many sunny days ahead,” concludes Ekenstam.
