OK, I am thinking about getting into the customer-sited Solar Panel/PV
installer business (residential and commercial buildings). I am
curious to know the following about US PV contractors:
1. in the US, what is the average revenue, profitability and # of
employees (more detail the better)
2. some metric that shows how many installs can a typical installer do a month
3. US PV install historical and projected growth
4. current size of market - installs & how many pv installers exist

I realize that there is some ambiguity here. It might make sense to
look at electrical contractors instead of PV contractors, so this data
would be helpful too. Anyone who can point me in the right direction
would be a big help!
