Anyone doing any work in this field?? Just got done my 15 code hr update and the instructor talked about getting certified by some nat'l organization of solar installers?? I have a chance to take a course, not much money 200 bucks but a huge time commitment, 10 saturdays from 8 to 2. It would prepare me to take the certification test from the nat'l organization. Not sure if I want to commit that much time although the coursework seems interesting to me. Not sure there is really any money in it?? Thanks, Jon
