What do you guys think about solar city? I am kind of impress the site survey they do without and contract or proposal. I got the survey and see the guy spend good 2 hours go through electric system, attic, and roof... Plus answer and provide a lot of good info.

It is great for the big company to do it. Sunrun and Sungevity never do it. Sunrun wants a signed contract before heading to the roof. Sungevity wants 50% of payment before moving their head. It is clear to show winner among those 3 companies.
