Does anyone have any recommendations for sources for solar energy system symbols or templates for Autosketch (or recommendations for upgrading to AutoCAD or LT)? I'm starting with designing a small system with about 10 photovoltaic panels for my house, but would like to work in the solar photovoltaic system design & installation business doing residential & small commercial systems. I've heard of people using Google Sketch-up for this, but I would prefer Autosketch since I already bought a copy of version 10. I posted a similar question May '09, but haven't seen any replies.
Thanks,
James
