Solar Energy is a key source to increase the transition towards renewable energy and to limit the carbon emissions in the atmosphere.

A large portion of solar energy worldwide remains unexploited.

This is also the case of the Nordic countries where climate challenges, legal and cultural barriers, and economic constraints prevent optimal exploitation of solar energy. 

In this context, the project Helios aims to turn the Nordic conditions into unique opportunities to accelerate the use of solar energy and the deployment of solar systems in the Nordic built environment through digital techniques using Trondheim as a pilot city.
