Best Roof-mounted Solar Panel Installation in Phoenix AZ

I was happy with the installation sunpower did on my project.  Everyone was helpful and informative.  The sales professional Greg Field was extremely informative and knew much more than his competitors.  Sunpower has been in business the longest in an overcrowded field.  My only regret is that I did not get more solar panels.

Got referred to this company, couldn't recommend the work more. Zach and his company had a super competitive/low cost, they were quick to communicate with me during the process and the end result is great. Got up and running in January, everything is fine and dandy so far.

They got a cool referral program where they'll give you (and me!) an extra 1k off your system. If you wanna work with these guys, let me know so you can save some dough!

I've never seen a company so committed to helping a customer. In every way, shape, and form my issues were addressed. Hands down, the best customer service I've ever seen and it was such a happy experience. Thank you Mike, for everything!

Working with Semper Solaris was a pleasure. Dennis walked us through all our options for the system. He made everything very understandable and let us know what to expect every step of the way. The rest of the Semper Solaris team also communicated very well and kept us updated on the project. They handled all the paperwork and made the entire process very simple.Thank you Dennis and the Semper Solaris team!

Run! If the home you are thinking about purchasing has solar panels maintained by this company, don't buy it! I really wish I would've researched this company before purchasing our home. I can honestly say, that at this point, I wouldn't have purchased the home. Yes! Over the solar panels.
The home we purchased, we have only lived in for a little over a month and in our contract, we agreed to have the solar panel lease transferred from the previous home owners to us. In the beginning, we thought, "This will be a great asset to our new home! We will save money with our energy bills!" WRONG! A week after we moved in, I received a call from a SolarCity tech, letting me know that the panels weren't producing enough energy and that a tech needed to come out to assess the situation. Three days later, a guy comes by, looks at the inverter and tells me that it needs to be replaced, that he has to order it and that someone will come back out to replace it.
A week and a half goes by and I haven't heard a thing. I call the tech department and speak to a gentlemen that tells me, "Oh I see it's been ordered, I'm sure it'll be in soon and as soon as it comes in, we will be right out to install it." As we get off the phone, I start to wonder about how our bill is going to work since our panels aren't producing what we are paying for, so I called back the same number and speak to a lady and I ask that question. She tells me that the company reviews the usage EVERY TWO YEARS and that if the equipment didn't produce enough energy, we will get some money back. What?! Two years!!
Meanwhile, we are suppose to be getting a "welcome" call from customer service. Which to this day we haven't received. We have however received a phone call from customer service but only because I emailed our sales reps and explained what was going on. When CS finally called, the guy said, "I'm understanding you're wanting a call from us." SMH. And don't bother calling their customer service, when I did call, I waited 35 mins. I did get a prompt that told me that I could continue to wait or that I could email and the response time for emails was 7-10 business days. Holy smokes! How is his company in business??
So currently, we have solar panels as decoration on our roof and no clue in sight of when they will be working again. Not excited at all about having to pay not one months lease but two because that's how they do things in your first month AND pay a much higher electric bill bc our panels aren't working.

UPDATE 8/31: I called the tech support with SolarCity and spoke with a woman that explained to me that the inverter that is currently powered off is the one to be replaced. I told her about the other inverter still having a communication status light on it, so she had me go outside to read her some numbers and I did. Have no clue what the numbers mean. She then told me that the status communication light was bc I didn't have the monitoring device plugged into the modem.
Ok, here's where the frustration lies 1) I had no clue what she was talking about. The previous owners did leave a device for us to plug into our modem BUT the sales rep told me that someone from customer service, during my welcome call, would explain how to set this up. 2) the woman I spoke with acted as though I should've already known to do this and that that was the reason the other inverter was showing the communication status. FYI, that would've been nice to know...the first time the tech department called me and told me there was a problem! She continued to tell me that I too can check what the solar panels are doing, through my power guide. I literally have no clue what that even means. I tried to ask what she meant and how exactly my modem is connecting to their panels AND that I still didn't understand what she meant by me being able to see this through the power guide?? No reference to a website or app or anything.

UPDATE: 9/18: New inverter was replaced.
The customer service, timeliness of product service/maintenance and ease of paying your bill with SolarCity is simply unacceptable.

The install process was terrible. Panels left in my backyard for days collecting dust. I was told it should have taken 2 days well it actually took a little over two weeks. Still has not been approved by Wattsup Solar. My panels have been installed for a month now and I still can not use them. The worst part for me was overhearing the workers talk about how the were not going to seal the holes on my roof because the company did not want to pay them their wages. Wow! What a sorry excuse for a "company."
