      Ekhi: From feasibility checks to confident designs in record time

      «One of the most common challenges we face is space constraints. We need to play around with different tilts and pitch, and this used to be quite a long process with several tools. The great thing about RatedPower is that we can simulate many scenarios, varying all these parameters, and have it done in no time. With the Layout Editor, we now see a huge improvement when fine-tuning our plant layouts.»
