Hi, I am a student doing a project on solar system and my building roof is a curved area.I would like to ask you if anyone can give me a hint of how to build a curved surface area in the PV SYST and place the PV panels on top of the curved a surface. I tried by choosing a portion of a cylinder but when I placed the 4 large Rectangular PV panels on the top of it. I got an error and it says that the orientation of the panels cannot take more than 2 panels. Thanks, Abdulrahman
