My system was only 12 months when it started malfunctioning. It's been now three months since I reported the issue to SunPower, and after 60 days and weekly calls to follow up, nothing has happened. The local dealer I bought this system from went out of business, read other reviews. It seems like everyone dealing with this company goes out of business.
Their customer service is terrible; they never follow up; their partner technicians are irresponsible and don't care about their work orders; hence things don't get fixed. There are far better companies offering quality solar systems to save yourself the hassle and look somewhere else; if I could, I would get rid of my SunPower system today.

After all the great talk by Sunpower representative, we decided to buy the system 3 years ago. The things went downhill pretty fast after the installation. In last 3 years, the monitoring system went down 4 different times. Since I was not monitoring the system every day, it took me some time to realize that the monitoring system was not reporting back the solar production. Every time it took them a couple of months to send someone and fix it. Finally the 4th time, their technician who came to inspect it told me that the monitoring system was faulty and they needed to replace it. That means another couple of months of wait.

The monitoring system is the least of the problems. Within 3 years after the installation, the inverters are not working properly. The energy production went down significantly in 3rd year. That means, I paid for the solar system and now I am also paying electricity bill. Sunpower technician told me that the inverters are not working properly for months. This is something Sunpower should have monitored on their own and fix it a long time ago. They had promised me a certain energy production every year and I am not getting that because they sold me a faulty system.

Now they tell me that they ordered the parts to fix my system and that I would have to wait another four weeks before they could schedule an appointment. At this point I feel like I am getting the run around. Sunpower gave me guarantee of certain solar production and they don't care what the system does after they sold it to you. If I have to buy solar all over again, I would never select Sunpower.

A couple of years ago we signed a lease for solar. I had one question for the Rep, we're planning a getting a pool later down the road. Would we be able to add more panels. He told us no problem, just give us a call. Well that was a lie and now we have a system that doesn't generate enough kWh and we're paying $173 a month to solar and a $100 a month to Edison. We're paying more a month now then we did before. Will not be referring then to ANYONE!!

I have been on hold with customer service for 30+ minutes. This is an awful company. They installed rails on my roof and no solar panels. The local 'dealer' is out of business and cannot be reached. Corporate refuses to assist in this issue. Stay FAR away from SunPower and anyone who claims to use them!

I will start by saying the installation process with Sun Power was excellent. They installed the panels quickly and were very responsive.

A 3.5 years later we need someone to come out and fix our system. I called on 8/26 and spoke with a very helpful customer support person. She walked me through some troubleshooting steps and we determined someone would have to come out to service our system.

This is where things went downhill. I was told I would receive a call within 10 days to schedule an appointment for someone to come out and fix our system. I was assured that it would most likely be less than 10 days to receive this call. This was odd. Why can’t they schedule it on this first call? Anyway, I thank her for the attempt at fixing it and waited for the call.

Fast forward to mid-day 9/6, day 10. No call, no email, no communication. So I call and speak with another customer service person. This person informs me that they ordered the parts to fix my system and that I would have to wait another two weeks before they could schedule an appointment. At this point I feel like I am getting the run around. No one mentioned anything about ordering parts. When I pressed him for more information about why I now have to wait potentially another 10 days for a scheduling phone call after waiting 10 days for a scheduling call that never came. He very condescendingly reiterated what he said about the parts. I thanked him for that info and hung up.

We’ve been without Solar for 3 weeks now and SunPower doesn’t really seem to care.

How do they know what parts they need if they haven’t come out to see what’s broken? Why can’t you make an appointment if you know what you need to fix and have parts?

After reading reviews it seems that SunPower has turned into yet another Solar company that takes your money, puts panels on your roof and wishes you the best as they laugh all the way to the bank. Should have waited for the Tesla roof.

App is great, can seen power gen and consumption in a jiffy.
Nice people. work gets done on time.
importantly, power gen fell below the design! they were quick and nice to settle the diff. Dealt with SunPower directly ... no middle man

The Sales representative Steve Gross was extremely helpful and supportive through the whole process. He was very informative. If he didn’t know the answer he would find out quickly. He even helped months after the install. He is the reason I increased my panels by 50%. SunPower is very lucky to have him.

The supervisor of the install worker’s was also very informative. I can recommend SunPower panels.

The team at SunPower did a fantastic job organizing, facilitating and supporting the entire job from beginning to end. The project management team was outstanding as well as the installation coordination. Even after the installation was completed, they stayed In touch to this day just checking in to see how things are going. Their customer service is phenomenal, and always willing to answer even the most silliest questions. My electric bill went from 200+ dollars a month to just $17 which is a connection fee. We are beyond happy with their product.
