Official opening of Norway’s largest energy system

November 16, 2022|

Today was a BIG day for celebration at TGN Energy. Together with our partners at Isola Solar AS and Hitachi Energy we’ve created Norway’s largest energy system for Revac in Tønsberg. Norway’s Minister of Petroleum and Energy Terje Aasland joined us to celebrate the innovation and initiative. Congratulations to Revac! At TGN, we’re looking forward to creating more fully integrated solutions with future oriented partners, continuing our contribution to the green shift and a more stable and flexible power grid. Stay tuned!

We join forces to solve the energy crisis for businesses

November 9, 2022|

We join forces to solve the energy crisis for businesses. Together with Lett-Tak Systemer AS and Isola Solar AS, we have developed E-TAK, an environmentally friendly system for new buildings that produces, stores and conserves energy in a pioneering, efficient and profitable way.

E-TAK is a complete solution consisting of a roof element, solar panel, battery unit and power management. By collaborating and quality-assuring interfaces during the course of the project, it offers the customer an optimal energy ceiling installed in the building.

Isola Solar and TGN Energy in Teknisk Ukeblad

October 19, 2022|

The Norwegian tech magazine Teknisk Ukeblad (0720) has a focus on green technology, among other things, and you can read more about our fantastic pilot plant and partners here (in Norwegian).

In a research project, everything must be investigated. In the above photo, IFE researcher Junjie Zhu pulls off a piece of ceiling covering with which they have covered the front of a bifacial panel in order to be able to measure exclusively the effect they get from the back. Photo: Mona Strande

TGN Energy signs deal together with Diggit

Roof membrane increases the effect of solar cells

September 29, 2022|

The Norwegian organization for the construction materials industry,, presents 50 building product innovations on their webpage and the pilot plant at Isola with TGN Energy’s solutions applied is presented. We are thrilled to be able to present a more efficient and complete solar energy system.


Through this project we contribute together with Isola to the development of more efficient and complete solar energy systems. This Norwegian-Chinese innovation project, Isola participates in the work to develop a complete energy system, where they have developed uneven light asphalt roof membranes which help to increase the effect of the solar panels. The solar panels are double-sided, which means that they derive energy from sunlight hitting both the front and back of the panels. The bright roof membranes reflect the sunlight so that the effect of the solar panels is increased.


In the project, which partly is financed by Innovation Norway, the partners have built the first full-scale pilot at Isola Skien, which since January 2020 has produced more energy than expected. Part of the reason for this is that the effect of the reflection from the bright membranes was better than first thought, is the assumption of the solar energy researchers from Ife assume.


The pilot is now undergoing further development, including the next generation of mounting feet and stands, which are also important elements in a complete solar energy system to be placed on the roof.

Håpets Katedral (Cathedral of Hope)

September 27, 2022|

TGN Energy and Isola Solar are proud sponsors of Håpets Katedral. It is an interreligious sustainable art project with a particular focus on the ocean. We have built energy systems with BIPV solar panels, battery storage and installed our TGN Grid solution to manage the energy.
