I have a 3.74 kw dc system. The full cost to have the system installed was $26K. I got a $10K rebate from my utility and a fed tax credit (it has been increased to 30% of the total cost so it would be $7800). Not all utilities will allow your meter to run backwards, mine does.

VAs are self-employed - not employed by others - so you'll be working for yourself: meaning you'll have to FIND that work for yourself.
