Solar is a bit more involved, but it can also be done. I am not a licensed electrician, but I have designed systems and helped physically build up to ~150kw systems (ground mount, nothing beyond ~20kw on a roof). Licensed electrician does the licensed electrician bits and signs off. If you're paying someone to do the install, you're probably going to pay between $2.50-$4/watt, depending on market. You can get down to $1.50-$2.00/watt if you do it yourself. Labor is unavoidable, the soft costs (permitting, sales/marketing load) is where the fat to be trimmed is.
I strongly believe we should be teaching every kid that goes through high school how to install a heat pump and small scale solar.
