Let me start by saying that the panels are excellent, but their customer service is horrible. I had SunPower put panels on my house in 2014. The first year everything was fine, even though I had to pay over $600 additional (over the monthly rental fee to SunPower) to the Electric company (Southern California Edison) due to low production. Since it was just above the minimum stated in the contract, SunPower was not responsible for this under-production. The second year we started having issues with the inverters that convert the sun's energy to electricity. After numerous calls over multiple months, the inverter was replaced. The replacement lasted less than one month, so again multiple calls with no results. Finally a service person came out who complained about the "cheap" replacement inverter and then proceeded to rewire the entire system. System worked properly for less than a month when again problem started. Calling customer service I was told in stead of calling all the time that I should just "reboot" the system to get it working again. Every two or three days I had to reboot the system and then it would go down again, each time showing electrical shorts in the system. Then end of the second year, I had to pay Edison over $1,000 due to under-production. Did not receive the promised payment for under-production because, according to customer service, "my system wasn't working properly and they couldn't determine the amount of under-production". Finally, out of frustration with Sun Power, I stopped the monthly payments. It took them 6 months of no payments before they acknowledged that the system wasn't working properly. They came out and replaced all the panels, checked the inverters and determined that there were wiring issues that they corrected. I told them that I would not start paying the monthly fee again until 3 things happened: 1. The system was functioning without issues for a minimum of 30 days; 2. All missed monthly payments were forgiven; 3. That they pay for the under-production from 2016 that was still outstanding. I also wanted a review of the original panel design since from the beginning the production did not meet the original intent of the contract. My payment to the electric company for 2018 was over $1,800 because the system did not function properly during the entire year. I am still waiting for reimbursement for 2018 under-production. All issues stem from poor customer service, poor system maintenance and a general lack of anyone taking responsibility for problems with the system. As stated, the panel as excellent, just be aware of the rest of the company. Still waiting for my refund for 2018 and now they are billing me $15 a month because they try to take my monthly rental payment out of an account that has a stop payment on it.

I’ve had a system since 8/15. The first year no true up bill. Year two 360$. True up bill. Year 3 $450 true up bill . Year 4 $1098 true up bill. This year on track for a$1200 tru up bill. This is not whaT I was told or promised. They will sell you a pot of gold ,don’t believe it, I have contacted, Them but a month gone by and nothing. They talk and talk but do nothing. They checked the system and say it’s working fine. No it’s not I can tell by the graphs! Here’s what I’m going to do, I’m going to have it taken off!

My complaint seems to be a common thread mentioned often in the reviews. My disappointment started when I purchased a house with 24 SunPower solar panels. I called SunPower and spoke with a representative, his name available upon request, and inquired as to how I could obtain on line monitoring to allow me to keep track of the solar panels and monitor their electricity production. I was instructed to send a copy of my Grant Deed, showing true ownership of the residence in question before the process could begin. I followed his request and an appointment was set to have a device installed in my residence to allow SunPower access to monitor my panels. The tech installing this device advised that I would be sent an email with a "password" that would allow me to enter into their internet app and monitor my system. His installation took place on April 2nd, 2019. Not having received any email with a password included or a telephone call by April 9th, 2019 I telephonically contacted the representative I had first contact with. I made no human contact but received a voice mail message. I identified myself and of the reason for the call and asked that he please get back to me with a password or at the least instructions if there were more I needed to do. I did not receiving a return call or email stating here is your password, or I'm busy I will get back to you, or any acknowledgement that I existed and was a customer using their solar system. On April 11th, 2019 I sent an email to the email address provide to me by the representative I first had contact with. This email was a plea for his response and his help. As of todays date April 14, 2019 I still have not had any contact with SunPower and its beginning to appear I am of no concern or interest to Sun Power. The solar panels are paid for and it appears they have no real reason to get back to me or offer CUSTOMER SERVICE AT THIS POINT .

I am surprised at the negative comments on this site. I have a SunPower 8.775Kw 'signature black' system that was installed Oct 2010. So it's been operating now for about 8.5 years. Not 1 issue. No maintenance needed, it just works. And does it ever work! The system has generated 88Mwh - which is an average of 10Mwh per year. That means my system consistently produces 120% over the rated value. I live in NJ so snow can adversely affect production, but I have a perfect SW clear exposure. We chose SunPower because the panels are on the front of the house. They look great, and the array almost covers the entire roof looking like a sleek jet black sunroof. Many people compliment the look, most don't even realize we have solar until I point it out. The real proof is this: my system has already paid for itself in cost savings of the monthly electric, SREC revenue and just yesterday we sold our home and realized at least $20K more than our neighbors becasue we have solar. We had a parade of very interested buyers wanting this house because of the SunPower system. This home won th SunPower Intelegant Award for residential in 2011 - which really helped our marketing. I am 100% sold on solar as a lifestyle and will install another SunPower system on the new home we are building in NC now. Keep in mind most people like me - 100% satisfied - don't take the time to write reviews. It's typically peole with an axe to grind. I think the SunPower products are great. SunPower might not be perfect, but they have been perfect for me as a real life long time customer. No hesitation to invest again using the same company.

You sent a e-mail saying you would get back to me, b ut I have never heard from your company again.

Everything was fine until I was forced to switch cable and internet carriers. I was able to locate where I needed to enter my new SSID and Password. Would nevr take it over a two day period. I called the 1-800 number and spoke to a service rep. She informs me that theres a $77.00 charge to enter my Network name and Password. I immedialy told her NO. I had already spent over $38,000 a year and a half ago and no they want more money. Watch your six if buying anything.

Well first off I would like to say the employees at sun power are the best everybody there is extremely helpful and knowledgeable the sales consultant that I worked with Rob G was just awesome I actually still stay in contact with him when I was in the market for Solar panels I got bids from several companies I decided to go with sun power because they seem to be the most sincere and honest and trustworthy people that really wanted to Find The right solution to my energy needs instead of just trying to sell me a product everybody else wanted to sell me a system with things I did not need or want but Rob G wanted to help me find a system that would benefit me over just trying to sell me something that I did not need i’ve had my system for just shy of a year this will be my first summer going into it with the Solar panels but I can already tell they are going to help lower my electrical cost and the price was a lot more reasonable than some of the other companies that I called to inquire about it because they did not try to sell me stuff I do not need or want but help me find a system that would suit my needs I wound up getting a 10 panel system that has room for expansion they kept me informed on every aspect of the job it was very little effort on my part they took care of everything all I had to do was approve the plans for the design which are very low impact solar panels instead of those clumpy ones that you see on a lot of Roofs The only thing I had to get used to was peak time from my electricity company but so far I love the job that they are doing and I’m Leavin a lot more comfortable without worrying about a huge Electric bill

I wrote a bad review a few months ago regarding customer service and how my system was not fixed even after 9 months. After 10 months my system finally is fixed. The next question was how they were going to compensate me for all of the power I lost. To make a long story short, their calculation of the amount of power I lost was basically the same as what I calculated. Then, they went ahead and paid per kWh as close as possible to what I had to pay. So in the end, I felt like they paid my losses in their entirety. I was pleasantly surprised. In terms of honoring their guarantee/warranty I will have to give them 5 stars. The final customer service person I worked with was also great. They did everything right in the end. I just hope the next time I have to deal with them they can do things right from the beginning in a timely manner.

This is my second home with SunPower Panels. The panels themselves are working well. This system has micro inverters which have given me trouble. The first year the Inverters started failing one by one. Finally they replaced the Inverters on each pane. Now about a year later it's happening again. Though the communications is good the service takes a lot of time. So far one month after the first call I finally saw the service techs. They were unable to repair and the person they were talking to on the phone said they will monitor the system and send someone back in April! Why they already know that at least two inverters are not working! RHJ Stockton, CA

My experience with sunpower capital plc is very negative. We sincerely regret having solar. I've had the solar system for two years and our roof started leaking about 3 months ago. The customer representatives are inexperienced, rude, and very unprofessional. They claimed the roof leakage is not related to the solar panels, but they sent an inspector who reported that panels should not have been placed on the weak roof. Please verify before you install solar, so you don't have headaches like us. We want to discontinue this solar so badly, but they claimed it's impossible due to the contract. May God have Mercy.

I am VERY satisfied with my solar installation and the SunPower panels. Frank C, the owner of Green House Solar has been responsive and informative. I interviewed other companies before choosing GHS because of the local ownership of the installer, and the warrenty of the SunPower panels. It doesn't take a crystal ball to see where the world is going. I'm glad I'm there!

I was not told by the salesperson that for safety reasons snow guards must be installed. At the first snow storm before my system was even turned on the snow fell like an avalanche from my roof damaging my awning. Thank goodness my grandchildren were not outside. I have a four year old autistic grandson who lives with me who does not understand danger The weight of the falling snow could have killed him Now I find out that I must pay almost $2000 to put snow guards on my roof so my home is not a danger zone So that plus the cost to repair my awning erases any tax benfit I was to have received. I certainly will not recommend sunpower to anyone

Very good experience and product quality

We got SunPower 6 years ago due to the apparent reliability of the company and panels. However, things started to be problematic almost instantly. The panels were on our roof for months before being turned on because the vendor did not complete paperwork properly for approval to activate them. Once activated, SunPower did not bill correctly, forgetting to send a bill for months and then asking for a multi-month lump sum. Then, our panels regularly underproduced and failed to get even close to what was promised. After long conversations where both the installer and SunPower ignored calls/emails, the installer finally admitted that the sales person lied about production and our situation. Our system performance connection kept dropping out. SunPower kept blaming us until they finally came out and realized that their device sending data was faulty and needed to replace it. We have had sound problems from the inverter, and when I've contacted SunPower through various methods (chat, phone, email), I have to follow up several times to get technical support to actually respond and schedule a visit (they also take no responsibility for the problems). Emailed questions normally go unanswered even though they say that is the preferred way of contacting customer support. I have sent 4 emails in the past 6 weeks and did not receive a single response. Currently, I have been trying to get a resolution about the Production Guarantee, and SunPower is taking no responsibility for ignoring that this reimbursement is to be done in cash. I am unable to get a response, and resolution is still pending. Customer service is polite, but not empowered to do anything except say no to the customer.

I would love to speak to a manager, customer representative from the United States. When the salesman who stood in my kitchen told me that Sunpower was a US home based company and local to me (Pasadena CA) I was excited. But now that I have had to contact SP for multiple issues I continuously receive customer service reps from India. Then if you would like to speak to a US rep they have to create a ticket which takes 24 - 48 hours to receive a call back. That's if your lucky to get a call back within that time frame. Its been 5 days and I have yet to receive a call from a US rep. Also I have roof tiles broken from the installation of the solar panels on my roof and have yet to have any one contact me regarding this issue.
