"Worst Service of any company I've ever dealt with. Pray you don't ever need it."
Reviewed Jun 12, 2019

Called the tech support line after an inverter (apparently) failed under warranty and is giving a proprietary code. I am a licensed solar contractor for 35 years. It was answered by a call center in the Philippines, not tech support. The entire system (Grid Tie Inverter, Sine wave Inverter & Transformer) was manufactured by SMA, which I am a certified tech. Sunpower tells me if I touch the unit they will void the customers warranty. He needs to call a Sunpower dealer (which he says he's left 6 messages for and has never received a return call) for service. They referred him to another dealer that he will now have to pay for another service call. That is a violation of the Magnuson–Moss Act and federal law that you cannot void a warranty and force someone to use a specific company - the homeowner can technically perform the service himself if he chooses. Even after asking to be transferred to a supervisor ( who I don't even think knew what an inverter is) obviously not in tech support, got no help. The homeowner is rightfully upset with this company.

"Horrible service and hardware"
Reviewed Jun 09, 2019

Sunpower monitoring systems are a joke, They have failed constantly, the first time because the whole unit just decided to stop working. The second time because of a 10 second loss of connection to the internet. The brain was too stupid to figure out to reconnect. Every failure has required getting through to tech support, which in and of itself is a challenge. They list as an American company, but their office is in Australia, and tech support in the Phillipines? If you want to be an American company, keep American business hours. I should not get a closed message at 3:30 p.m. With over 1b$ liquid assets they can afford another shift.

"Rudest Sales Person Ever!"
Reviewed Apr 29, 2019

I wouldn't even recommend talking to this company! The salesperson showed up in the middle of me cleaning my kitchen grout yet I proceeded to speak with him and he forced me into an appointment even though I stated I wanted to speak with my fiancé first. He showed up for the appointment but I had totally forgotten about it so he called my phone 3 times and texted me. Once I texted him back apologizing and telling him that my fiancé was not interested in this he proceeded to tell me that I wasted his time and I should be more respectful of other people who are trying to help you! Not the way that any salesperson should ever speak to a potential customer ever! Now we would never consider this company ever! Not a good first impression.

"16 SunPower X22 360 watt panels installed on my San Jose, Ca Home"
Reviewed Nov 16, 2018

I have worked in Technology all my life and I have received Solar quotes for my home from over 6 companies. I decided to utilize Sun Power panels to create the most power from my south facing 2nd floor roof. I fully understand the advantages of AC power coming from the panels and the 25 year warranty provided by my local SunPower installation team. My system was installed in late August and to date has generated about 1/3 more power than I use. I realize that will drop as we move into the winter months, it is now being impacted by the smoke coming down from the California wildfires. My next step is to install a battery storage system which I will probably buy from Enphase.

"1 star is 1 too many!"
Reviewed Nov 06, 2018

I contracted with SunPower in 2015 because a trusted family member worked for the company and sold me on the merits of the company and their panels. For the past nearly 3 years SunPower has consistently UNDER DELIVERED. In 2018 we’ve had over 3 months with no solar power due to a faulty inverter. No solar production from June 24 to August 2 and again from September 15 to present (November 6). Absolutely NO communication from the company. Email goes unresponded to. Phone calls all elicit the same response from a foreign accented person stating its being investigated The local electric company that installed the panels has bankrupted and the company assigned to our account doesn’t return calls. SunPower has been 100% unresponsive. The only time I hear from a representative is when I leave a scathing review, yet issues are still unresolved. I absolutely cannot recommend SunPower. We are now seeking legal remedy!

Very happy with Sunpower solar panels and the installation by Freedom Solar. Our entire electricity bill for the first full 12 months with solar panels was only $199...that's for the entire year, not monthly. And we live in Texas! In a 3700 square foot two story house. Both Sunpower and Freedom Solar have been very responsive to any minor issues and updates to the system. Couldn't be happier and highly recommend both companies!

"Yay for Solar, terrible customer service"
Reviewed Sep 11, 2018

This company has been an absolute nightmare to deal with from day 1. Their communication is terrible. No one talks to each other, it’s impossible to get a hold of anyone who knows what’s going on. We had various things scheduled along this process to get the solar panels installed. Not a single one happened on the day it was scheduled. We had people just showing up at our house with no notice. And we took time off work to be home only to have no one show up. Do NOT go with this company.

Even the installer said that they were having a lot of issues with the inverters that they were installing and within 1 month my system is down and now 3 weeks with not so much as a call back to have someone come out and fix my system! From the 3 times we have called it took over an hour to get a rep on the phone with no resolve.

Very pleased with our E-20 AC Equinox system. It’s the nicest looking solar array in our neighborhood. We purchased it after a great deal of research. Glad I put in the time. No electric bill since installed and we live in the Northeast. Cost more but leaps above the other systems in looks and performance as far as we can tell. For 2 years it has produced around 127% more than we used on average.

I'm now on my 4th inverter, average replacement has taken at least a month, just to get a tech out to look at it, then usually another month to get it replaced. Add the fact that when you call for billing questions, I've been stuck on hold for over an hour twice now. Finally submitted to the option of leaving a voice mail, never to receive a call back... Their panels maybe great, but their customer service sucks, I'd look elsewhere for solar...

SunPower panels are the best panels available on the market. They are the top shelf of the solar industry. Not only do they look way better than any other panel, they are the most efficient, and backed by the best warranty. By far the best value in the solar industry. Plus they vet their dealers so you know you're working with a good company if they are a SunPower dealer.

"Be your own electric utility company"
Reviewed May 08, 2018

We've had our 6 kw pv system now for 15 months and have been impressed with the results. We have saved more than $1,300 while supplying 2/3 of our total power needs since the install. In fact, based upon our experience, we decided to purchase a Honda Clarity plugin hybrid electric car in March. We've driven over 1,400 miles and used only 4 gallons of gas. The rest of our car's energy comes from our Sunpower system at about half the current cost of gasoline. We plan to add some additional panels in the near future to provide an even greater portion of our energy needs. We love the app for the computer and smart phones to instantly retrieve lots of real-time data about our current and historic energy use and production. A great feature! We are delighted to have made this investment to be energy self-supporting for now and for many years to come. Glad we chose the Sunpower system.

"Sunpower by Positive Energy Solar Review"
Reviewed May 07, 2018

When I first started looking into solar energy for my home, it quickly became very confusing trying to compare the various panels, inverters, types of installation, etc., even with an engineering background. After much research, I came to the conclusion that the best equipment and best value for the money was Sunpower. There are two companies that install Sunpower equipment in the Albuquerque area and the best priced of the two was Sunpower by Positive Energy Solar. Unlike many service providers I've dealt with in ABQ, my experience with Sunpower was top notch. They were professional from start to finish, did their work on time and charged exactly what they said. My system has been running for two weeks now and production is what was claimed with no start-up glitches at all. I highly recommend (and commend) Positive Energy Solar, Jim Pettegrew and their work crews.

Almost a year in and we're seeing significant results daily. Our dealer, SolarTech, put together the right solar package for our needs and we're tracking on point. When looking at panel providers, the 25 year warranty was critical in our decision as well as SunPower's commitment to clean energy. This is what they do and they excel at making the best panels available.

There are a lot of reasons we went with Solar Tech (our installer) and Sun Power. Local rep who was extremely knowledgeable; a product made in the US - with all components made by SunPower - not parceled together from various sources...and the option to add pool solar at the same time - all as part of the same package install.

"It wast good experience"
Reviewed May 03, 2018

The sales process was easy, but the installation was a little cumbersome. The fact that their base is in Charlotte and Anderson, SC is two hours away, made the process slow. The installation took more than expected and did not pass the first lllocal inspection. Making the small corrections required took a couple weeks, and then almost a month to power the system. There were some ridiculous hiccups with duke power to aprovve and install the new meter but it was solved.
As far of the system itself, it is not producing as much power as expected, but it is just fine.
The service was good, the project manager answered all my questions but she should be more proactive communicating the status, instead of waiting for the client to call.

Reviewed May 03, 2018

Put 15 365 watt SunPower panels on a pole with a SunnyBoy inverter right at the pole. On a slight hill behind house. Beautiful sight. On a clear day the panels easily reach 5,000+ watts/hr production of a theoretical max of 5,475/hr watts. And when it snows I crank the array to it's most vertical position and the panels clean themselves with some wind assist and heat produced. Nice.

"SunPower in New Mexico is the real deal"
Reviewed May 03, 2018

SunPower's local affiliate - Positive Energy Solar - from start to finish - always did what they said they would do.
From my initial visit with a SunPower sales manager, through several tries at sizing the "right" system for us, to efficient visits by the project manger, designer (layout on our flat roof), etc., to the installers (one-day job - amazing!), to follow-on calls to get information for my taxes, SunPower never disappointed.
There are a number of solar companies in New Mexico, many good ones, I'm sure, and several of which I interviewed along with SunPower. But SunPower always stood out. They are credible, customer-oriented, and performance-driven.
You may make a different choice and be happy, but I suggest that you at least include SunPower on your short list.
Oh, and the cost of the system, which is providing more energy than we use on most days, was quite attractive compared with other offerings. The excess we supply to the PNM system will be useful when our air conditioning is needed this summer.

"SunPower Above All Other Panels"
Reviewed May 03, 2018

After an exhaustive research into different solar panels, I learned there are premium panels, decent panels and garbage panels. I won’t get into what criterion I used for brevity sake. It was quite obvious that SunPower solar panels are premium panels. I was able to negotiate a price to purchase that was very close to lower tiered panels. It has been five months. I was skeptical at first of generating 10 SRECs a year as estimated by the installer because my panels were installed during one of the worst winters in record in terms of snow accumulation. However, after earning more than 1 SREC a month for March and April, I am confident of earning 10 SRECs a year.

Spectacularly poor service. We've had panels on our roof for months. They're completely unable to be activated. All I've received from SunPower so far are broken promises and updates that never come.

"Great panels but expen$ive"
Reviewed Sep 27, 2016

I think it's clear Sunpower makes the best solar panels, but you pay a price for them. My prediction is that the technology will keep getting better, and in 10-15 years you may want to upgrade your system anyway, so why would you pay a lot for premium panels with a very long lifetime? In 15+ years, the low cost panels are likely to be more efficient, and you'll want to replace your (golden) Sunpower panels, anyway. But, if you must have the best - and cost is no object, this is the best.
