Would love to get involved in that kinda work (unreconstructed hippie that I am ), but haven't had any calls for it. The biggest RE project I have been asked for was a 240V line into a garage to power an EV charger.
HomePower magazine has a lot of good practical information, including a monthly column on the NEC and how it applies to RE systems. http://www.homepower.com
