They&rsquo;re used by the world&rsquo;s biggest solar panel producers and leading R&amp;D labs to assure the quality of their panels. We make sure they can be sure about what they produce. We also provide PV testing services ourselves in both Rotterdam and Valencia harbour and inline testing services in China, India, Vietnam and other PV manufacturing countries. You could say we wake up every day to assure the world of solar performance. And with solar being well on it&rsquo;s way to become the world&rsquo;s leading energy source, we believe that certainty is needed. In the end, nobody likes to waste energy. We are sure about solar.
