I got a competitive bid that was exactly the same products as the others, But with substantial savings. I wanted assurances that it would be finished this 2019. They did it in 2 weeks, including my new roof at the beginning of the process. Sunny and Bruce offered communications that were excellent and answered all my questions throughout the process. As it turned out the system size that was recommended to me, based upon them looking at my electric bill, turned out to be only producing three-quarters of my actual consumption the next year. I said I wanted to buy 10 more panels to fix that, and they said no!! we sold you an inverter that won't handle anymore, and you would have to flush down the toilet your Inverter and start over again. My initial wish was to fill in as needed in the future and they were made well aware of that when they were busy selling me the year before. Total disappointment of my goals.
