Was pretty good experience. Nice to get multiple quotes all in one place, all in the same format, without having salesmen wasting your time and giving you the hard sell. Also very nice to be able to click on links and check out the specs on panels and invertors contained in each quote. Did get a lot of emails and texts from a few companies trying to convince me why they were better, but that's better than having a salesman in my house blowing smoke up my shorts. I did have one company not affiliated with energy sage come out and give me a quote. Ridiculous price and a lot of smoke being blown my way - pretty much confirmed the value of using energy sage. The only real let down was my energy sage "advisor". Their available phone times did not fit my schedule, and questions asked by email went unanswered or when they were answered, the answers really didn't help much. If you wish to make an informed decision, you are going to have to do some research on your own. That being said, I did choose a company from my energy sage quotes, and if I had to do it again, I would use energy sage again. My system is not yet installed, so whether or not going solar was the right choice remains to be seen. As a final note, I have a shingled roof, and the shingles were old enough to need replacing - something to consider. If you put a system on your roof and need to reshingle years down the road, the complexity and cost of the re-roof will be much much higher. And I discovered that having a roof redone is NOT cheap. That alone is costing me as much as the solar system. That part sucks, but in my case, I could not see any way around it. So, I'm pleased that I found energy sage, as it definitely helped in making a decision. Whether or not the decision I made pays off for me remains to be seen.
