"When solar power leaves you feeling burned"

[robby]

That's been my experience as well, I've tried 3 different local installers, all of them make used cars look like an honest profession.

Best way to find a good installer is typically by word of mouth.
Nothing beats meeting a happy client and getting a tour of their setup and then judging the workmanship yourself.
It's a Bonus if the owner will spend the time to go into details and tells you all the good and bad experiences of dealing with them.
