I been researching the solar installation costs and companies. Every solar company claimed and gave the presentation to impress us on how great they are for such a cheap price, I got quotes from 9K to 28K (all without batteries). At last SunWork didn't try to sell us anything but gave me crisp quote and gave enough time to decide.
I am grateful to John for adjusting on installation timings as well as being patient for my questions. It was great experience yet functional system without headache.
