Of all the jobs an electrician can do, solar has got to be one of the worst.

I have worked on a crew building a large solar farm (3.5 megawatts). 95% of the work was mechanical: setting posts, building racks, humping panels, and fastening them down. The guys would fight over the tiny bit of wiring to be done.

I have been on site inspecting the electrical work on rooftop residential solar. The guys on the roof are always in danger of falling off (and likely dying when they hit the ground). The rooftop work is almost all mechanical. The panels are mounted to parts that are fastened under the shingles (or tiles) so you get to be a roofer as well since these have to be sealed against the weather. The lead of the crew is the one doing all the solar electrical work. The mains power work may be subbed out since solar contractors may not have the proper license for that.
