    *** If you are considering CleanFactor Energy, one piece of advice for you: DON'T DO IT. JUST DON'T... unless you like throwing your money away and wasting your time. This company cannot be trusted and Philip Mickelson (the owner and only employee) is the reason ***

    Things started off well with CleanFactor Energy. We contacted them since they were on the authorized list for GoSolarSF. Phil responded right away and we were able to schedule an appointment for a site visit the next day. He showed up and did a thorough job going over the various aspects of the project. He really took the time to answer all our questions. It's a big investment (15k+) so we wanted to be sure we chose the right team to do it. We later found out that Phil is pretty much the only person in this company so keep that in mind when you evaluate a project that comes with a 10+ year warranty. What are the chances they are going to be around to support you?

    Everything changed once we sent in our initial deposit of $1000. Suddenly, Phil would be nearly impossible to contact via email or phone. We were lucky to get a response once every couple of weeks. When we did get a response, it turns out that almost none of what he was telling us was true.

    The design and permitting part of the project was supposed to take approx. 4 weeks. 8 weeks into the project we discovered that Phil never even drafted plans or applied for a permit. Wow! I had to call the Department of Building Inspection to see what the holdup was, and they had no record of any activity from them. This was after he repeatedly assured us that the application was already submitted and approval was imminent. Despite our better judgement, we decided to give him ANOTHER 4 weeks to try and make things right. To no one's surprise, Phil made zero effort to even file for a permit. To this date, he has not filed for a permit.

    This project was projected to take 6 weeks from start to finish. We are still dealing with the fallout 6 months later. We've repeatedly asked for our deposit back and Phil doesn't even have the decency to do that despite all of this being his fault. From his older reviews, it looks like something happened in 2020 and they'll be out of business shortly (if they aren't already). The most recent reviews echo a lot of what we've experienced.

    CleanFactor Energy is by far the worst contractor we have ever dealt.

    It hurts to write this review.. we worked with Phil for months to get our solar lined up. We paid a deposit, they submitted the plans to our county in August... and never followed up or submitted the plans after comments/review. We phoned and emailed many times and the last return email I received was on September 5th 2020 (it's not November 4th).

    We were very much looking forward to offsetting our pge bill as well as some taxes we will need to pay next year.

    Overall Phil started the process as a 5 star vendor/business that came highly recommended from a coworker. They have turned into a 1 star vendor/business that has no follow up/follow through.

    We have asked for a refund of our deposit, but I feel like that's a long shot, which in infuriating...

    Stay away of looking for a solar company.
