If we can make it here, we can make it anywhere

Building a modern house that is self-sufficient on solar power is one thing. Doing it in a place where sunlight is absent for months at a time is something else entirely. This is why we initiated an experiment to prove that solar power, when combined with the right technology, can be a key part of the sustainable energy solutions of the future, even in the darkest of places.

The unique power supply system makes our off-grid house support itself on solar energy. Even in the dark.

When the house at Vitberget in Skellefteå is completed, it will be a very special home. Even though it may not look like it.
