Lima Posted July 17 Share Posted July 17 why is the near shadings for a tracker system with 13 degrees and a minimum above ground of 2.1m has 0.3% near shadings and that of 60 degrees and 0.5m above ground has almost around 3%? How does pvsyst calculate this? Link to comment Share on other sites More sharing options...
Michele Oliosi Posted July 18 Share Posted July 18 The minimum height above ground is not very relevant to the near shadings. If your trackers go to 60° rotation angles: - it means they will follow the sun much lower than the 13° ones, inducing more mutual shadings if backtracking is not active - the diffuse component is also subject to more mutual shadings Link to comment Share on other sites More sharing options...
Lima Posted July 18 Author Share Posted July 18 What is then difference between near shadings and electrical string shadings? Link to comment Share on other sites More sharing options...
Michele Oliosi Posted July 18 Share Posted July 18 near shadings : irradiance loss electrical shadings : electrical mismatch loss caused by partial shadings Link to comment Share on other sites More sharing options...
