WE ARE ETERNAL SUN

We build high-end simulators that recreate sunlight. They’re used by the world’s biggest solar panel producers and leading R&D labs to assure the quality of their panels. We make sure they can be sure about what they produce.



You could say we wake up every day to assure the world of solar performance. And with solar being well on it’s way to become the world’s leading energy source, we believe that certainty is needed. In the end, nobody likes to waste energy. We are sure about solar. We’d like you to be too.
