The 320 kWp solar system creates new energy on an otherwise untapped roof to the delight of the farm owner, tenant and the planet.

“As a building owner, we are committed to ensuring that our buildings are sustainable and attractive to tenants. Using the roof to produce renewable energy is a good choice, both economically and for climate reasons,” says Aage Hagen, partner at Portal Eiendom.

Sunday Power is the developer of the project in Årvollsskogen in Moss.

The plant will produce 272,000 kWh a year, which is equivalent to the electricity consumption of 17 households.

This is a collaboration we are proud of. Here we produce renewable energy without making new interventions in nature. The photovoltaic system has increased the energy rating of the building from C to B. We see the process of increasing the energy rating of the building is an ever-increasing motivating factor for building owners. It is both driven by increased demand for greener buildings from tenants and the fact that banks favour more sustainable property portfolios,” says Ole-Bjorn Horn, Client Executive at Sunday Power.

Isopartner is a supplier of technical insulation, and has its head office in the building. The products they supply are approved for BREEAM projects and help make buildings greener. The fact that the building they hold in has increased in energy carats is seen by them as very positive.

“We are proud that our head office uses locally produced electricity from the roof. Sustainability is at the core of our business, and the fact that the building we own has become greener is very positive,” says CEO Arne Schultz and project coordinator Mette-Regi Olsen of Isopartner.

The photovoltaic specialist is the installer and subcontractor of the plant.
