The company I work for recently started installing photovoltaic systems. I've worked on 2 of the jobs (1- a 6300 watt system, the other a 3000 watt system), and my initial impression is that going on the roof sucks (to put it bluntly). I don't mind doing all the other work involved, but I really don't like working on the roof. I am a strong believer that these solar panels are going to be huge money makers in the next 15-20 as the demand for energy increases and I'm just curious as to what other electricians experiences have been using or installing them.
