I review and issue permits for solar systems. Solar City and Namaste are pretty busy at it these days. Not that I just suggest turning to the "big names", but with solar, the industry is changing and complicated. I have seen a couple installs go very bad due to lack of experience. I can also speak well of the folks in those companies that I have worked with...seem pretty professional. Well prepared plans, passing inspections, playing nice and following the rules.
Solar is becoming pretty popular...issuing lots of permits for them these days.
