  • "Love my solar system!"

    Reviewed Apr 10, 2021

    I was very impressed by and got great service from the sales rep, who was extremely knowledgable, and the managers I spoke with during the purchase and installation process. The sales rep was much more informed than competitors and explained the system and panel technology in great detail. The installation itself went quickly and smoothly. But in the months in between the purchase and install, there were times when I would not get a response from the project manager for weeks at a time. The manager(s) above I then contacted were great about getting things going again.

    I love everything about Sunpower except for the lack of communication during the project management phase. They have a top of the line product, I'm over a year in, and the system has worked perfectly 24/7!

    We chose Energy Concepts and are incredibly happy with our decision. We highly recommend Energy Concepts to anyone in the market who wants to get what they pay for. We worked with Dean who was outstanding and able to address all our concerns. We chose SunPower equipment for its efficiency & power, single supplier approach, simplicity of design and documented reliability. EC was extremely flexible on the project start date, which was an important factor in our decision. Brianna and Dean kept in constant communication throughout the project. Lorenzo and his team were outstanding during the panel install. Wally and Chris were outstanding during the electrical work and City Inspection. The quality of workmanship is above reproach. The system is performing above estimated output already. Specifically, EC designers estimated around 550kWh for February and this system produced 787kWh. March is looking just as strong as February despite the stormy days. This process has been an incredibly positive experience from start to finish.

    From the initial quotation stage, through the system design and installation and all the way to turning the solar system on, Sunpower has been great. They were knowledgeable, and educated me about our solar system; professional and more than competent when they installed it; and it is working as expected. We're very pleased.

  • "A very smooth process"

    My experience with Sunpower has been an excellent one from start all the way to completion of the project. It started with Steve Gross (Sr Energy consultant) who explained in detail all I needed to know about getting a solar system. I have to admit he sold me. Next was the site survey, followed by installation of the panels and associated electrical components. Jessica Espinoza was really on point as the POC by facilitating all the necessary administrative paperwork. Kris McDonald as Project Coordinator was superb as she helped complete the whole process all the way to supporting me in accessing and getting the monitoring app to work. I felt great when my system started producing clean energy and had no buyer's remorse at all. Thank you Sunpower!

    If you ever need anything from them, please expect it will take at least 5 - 10 phone calls, at least 6 to 8 weeks to resolve, promises of calls back that never take place and repeated lies.

    Last February (2020) our solar went down due to a part they decommissioned and did not inform us of. In July our electricity bill was $500 so we contacted the company to find out what was wrong. It took until October for them to send someone out for a 15 minute work-order to fix the problem. 4 months of weekly phone calls and promises someone would be out soon. 4 months of 'we'll call you'. 4 months of $400-500 electricity bills for a part they took off line without informing us. 4 months.

    They have a performance guarantee that states if your solar doesn't perform as expected, they'll pay you back. Our solar was down for 8 months because of their actions and we are getting just slightly more than $1,000 back. The solar itself costs more than $200 a month and that doesn't even account for the multiple months of $500 electricity bills. The guarantee is a joke to say the least but a $1,000 is a $1,000 so it would be nice to receive.

    The report that told me the pittance they would be returning to us came out in November of 2020. I was told on one of my numerous prior conversations that the check would be cut in 4 - 6 weeks. I called in February of 2021. They don't know what I'm talking about and someone will call me back in a couple days. I called again today. The check will be cut in 4 - 6 weeks, just be patient.

    If nothing ever goes wrong and you never have to deal with this company, I'm sure it's wonderful but it's been 13 months for one issue. Isn't that long enough?

    The power output from our SunPower home solar system installed three years ago by Bluesel Solar has declined significantly. After inquiry our installer informed us the SunPower microinverters are known to be defective and several on our system have failed. All the microinverters have to be replaced (you will see in other reviews this is a common problem) and SunPower will not commit to replacing them until sometime in the undefined future (even that is not in writing). Its been 4 months, but maybe next fall???Bluesel abdicates all responsibility. SunPower will not commit to compensation for lost power, unexpected delivery charges, or lost solar energy credits. No one informed us of this problem and it was only discovered when we started receiving unexpected energy bills!

    Sunpower does NOT allow you to access per panel stats or metrics ... their monitoring app provides array level rudimentary data, but in order to get any info on how the system is actually performing (beyond gross 30,000' view stats) you need to beg your installer to provide you the data ... invariably, they treat you like you're asking them to go out of their way ... I have no way to know if the stated performance is actually being delivered or if the panel is performing to guarantee unless I beseech my installer to give me the data

    installation was in a day and a half. remarkably quick.
    company was very responsive in making this happen. (E2 solar)
    The only thing that disturbs me is that the inverter at peak times can't handle the power produced by the panels. This happens I guess when it's cold out and the panels are pointing directly at the sun, (not at any angle). It's known and called "solar clipping". The excess energy is shed by the inverter and lost. IT's only a small amount of power at the peak environmental conditions, however I'm puzzled why a slightly larger inverter wasn't chosen to avoid this energy loss all together. So 4 stars instead of 5.

    I have had my system on for a couple of months and I absolutely have no doubt that going solar was a great decision. My system has an estimated offset of about 110%. This allow me the peace of mind that if I put in a pool or grow my family, my system will still be big enough to accommodate. I also bit the bullet (the cost can give you sticker shock) and got a back up battery (Tesla Powerwall) to accompany my system. I decided to do this because the 26% tax credit basically covered the additional cost AND I wanted peace of mind that I would still have power even if the grid went down. WORTH EVERY PENNY during snowpocolypse in Feb 2021 in TX. My subdivision was without power for almost 45 straight hours and I was completely unaffected. I didn't have to worry about my heater not working and losing all my food due to the fridge not being on.

    Last summer on a Saturday night I watched a Sun Power infomercial and made a phone call. Later that week we had a meeting with a local installer who provided us with a quote for a new roof and our solar system. I did the math and made the decision to buy the system outright. We had our roof completed in November and the solar panels installed a few weeks later. The installation took about two days to complete. The guys were professional and did a great job. It took about four weeks for our local utility to come out and change out the electric meter. A week later the building inspector signed off on the install and we were ready to generate power.

    I like using the app to see how much power we are generating and how much we are sending back to the grid. Three months into having our solar system we are already seeing savings in our electric bill. Cant wait for the summer months to see how much we can generate. The best day so far has seen generating 400% of our energy use.

    It looks like we made the right decision.

    I was either completely lied to or just flat out misinformed during my consultation call last night. I am both offended and appalled by such horrible sales behavior and tactics. I informed the consultant that I received multiple quotes from competitors of systems in excess of 10 kW, and she took that as an opportunity to bash the competition with misinformation. This is completely unethical.

    I just finished my call with National Grid and confirmed that the information I received last night was completely false.

    I was told by your rep that a system over 10kW would not qualify for the Massachusetts SMART program. FALSE. All systems up to 25 kW qualify for the full value of the SMART program. In fact, the larger the system, the more you stand to make from the SMART program.

    I was also told that a system over 10kW would not qualify for net metering - Somewhat False. While a system over 10 kW does not qualify for the full 100% value of net metering, they do qualify for the market rate which is currently 60%. There is also an application for exception to this to get the 100% net metering. Also what's frustrating is that this is less relevant for a home with high usage and a system with energy storage which is what I requested. There would be very little, if any, production going to the grid anyway.

  • "Terrible Customer Experience"

    Reviewed Dec 28, 2020

    We signed a lease for a SunPower system in July of 2016. The first year, the system performed beyond the guaranteed production. Each year since then has seen diminished returns.The lease is structured so that if the system is underperforming, a refund is issued at the end of the year to cover the difference in what the electricity savings should be. However, it does not cover what the average output was. Our savings would be greater if we received a refund based on average return.

    In the winter of October 2019-20 the system failed to report energy production to the energy company. According to the Sunpower "dashboard" (customer interface) the system was producing properly. It took four calls to Sunpower customer service and two calls to their service subcontractor to get a response. It was four months before anyone came to look at the system. They finally came and replaced a part. They system began reporting again but it continued to underperform.

    This winter the exact situation recurred and I am still trying to get service after three months from my initial call. Sunpower told me they were referring the problem to a subcontractor (Sun Systems) and making it a priority. I was unable to reach Sun Systems on the phone so I tried emailing. I received a curt email response several days later saying they were waiting for a part. After two weeks I still had not heard anything. In a follow up online chat with SunPower ( (they never answered the phone and it finally hung up on my after 20 minutes on hold) I was told Sun Systems actually did have the part. SunPower said Sun Systems would need to replace all the panels. I asked SunPower how I would know when Sun Systems was coming out to do the work, what the problem really was, and how I would know it was completed. They said Sun Systems would contact me. I told SunPower I would like some assurance they would follow up with Sun Systems, but the customer service rep refused to agree. I finally asked to speak with a supervisor, and was told one would call me back within 48 hours. I never heard back. My system is still not reporting and I am paying the energy company for almost all electricity use.

    SunPower has gone through financial troubles and recently spun off their manufacturing division. DO NOT buy or lease anything from this company. Terrible product, terrible service. I wish no stars was a rating option.

    I contacted Sunpower to describe the situation and how I was not comfortable with the errors I was that I was receiving or the low power output (less than 2.5kw average for an 8kw unit on a sunny day with few clouds). They kept giving me runarounds to avoid scheduling a service visit. Very scammy. Called multiple types: same response of 'we'll get back to you in a few days.' Reading BBB reviews other people have reported similar stalling tactics.

    Beyond the defective unit, I also signed up for autopay to get a discount only to find out that the autopay failed to work on the scheduled date resulting in no discount and a late fee. Still no response from billing to correct the issue.

    To put it frankly, this company needs to go out of business. It should be illegal for companies to operate this way. They have a legal obligation to ensure their units are functioning correctly and do not pose a hazard to the home. What they are doing is downright criminal: locking people in 20 year leases and failing to provide the leased service.

    I'll be contacting a lawyer within the next week to see what my options are. This company must be owned by the devil.

    "Great panels and installer, terrible monitoring site"

    Reviewed Mar 22, 2020

    We installed a 10kW SunPower system two years ago. They are rugged and reliable panels. We were initially impressed with the layout of the SunPower site. We also have our SolarLog meter and site to track power generated for SRECs. It's a good thing that we have the SolarLog site. For example, today we are maxed out at 9.8kW at peak generating conditions. The SunPower site shows 0.2kW. They claim that we would be able to track power generated vs power used, but that is false. The site is useless. We have to do that manually by watching the power companies meter. All requests for SunPower support have gone unanswered. Our installer has tried their best to be sure the CTs are placed and functioning properly but have thrown their hands up in frustration with the lack of factory support. Maybe someone there will read this, maybe not. But beware, if you don't have another way to monitor you panels, you will be very unhappy with SunPower. I want to impress upon the reader that our installer, BluSel, is fantastic.
    The manufacturer is at fault.

    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.

Sun Power has been nothing but one disappointment after another. Complete rip off and stuck with a 20 year lease. DON'T GO WITH SUN POWER. Run away and go with anybody else.

    Reviewed Feb 27, 2020

    I had leased SunPower panels installed over six years ago. They worked perfectly for about six years. I had an inverter fail in December. It was causing ground faults throughout our home. I used the SunPower app to report the problem. After more than a week and no response, I called. After some tests directed by the person on the phone, I was told I need to schedule service and shutdown that inverter. I got a call back from the scheduler after eight days. The scheduler said the first tech opportunity to come to the house was five weeks out. I asked if the tech could bring a new inverter and was told no, he would only diagnose the problem. The tech showed as scheduled, and affirmed I needed a new inverter, which they already knew by error code! I was informed that it would take about two weeks to order and to communicate with another scheduler. I don’t know when the repair will occur but it is likely at least another month out. I’m estimating end of March at best. All during this 3 month period, I have about 60% of my solar panels out of service. Terrible customer service!

    Update: SunPower scheduling texted me at 2PM and indicated that I had until 4 PM to accept their proposed timing to visit my house for repair, or lose the slot. Nice that it was only one week since the tech visit. Pathetic that the first date available is April 17, 7 weeks from now, to fix a problem that has the majority of my solar PV system shut down since December! Also incredible when you consider that I live in Santa Barbara, CA, perhaps the most robust solar market in the US, and a short drive to the SunPower Corporate headquarters. BUYERS BEWARE!

  • "worst company ever"

    Reviewed Jan 15, 2020

    I have never written a review before but this should be said since this company is absolutely terrible and I would never recommend them to anyone.

    My wife and I built a new house starting in February, with the new law in California, we have to have solar for new homes. Our builder contracted with this company and was not our choice to pick them for our solar.

    We were told a couple of months before we moved in which would be in October of 2019 that half our panels were not functioning correctly and that they would need to fix the problem before we move in. We are in January of 2020 and the problem is not fixed.

    they had someone come out and do a service on the panels. they worked on the panels for several hours. After they were done, no information was given to me he finished whether or not the problem was fixed, I was home the whole time. A couple of weeks went by and no information was given still if the problem was fixed. My wife called and asked if the panels were fixed or they still needed to come out. Their response was that the report was not in and that they don't know if it was fixed. Another couple of weeks later they call to schedule an appointment to come out to the house. When the tech was working on converting the panels to start, she realized that the work from the previous person was not done and the panels were still not fixed. So their own company is not communicating with their own employees on what is fixed or not. So she had so leave without doing anything since the panels are still broken.

    Weeks have gone by and no phone call was made to get the panels fixed, so i called the company. They said there was a work order in and that they are working on it. They said they outsource their installtion and that they would have them contact us to schedule an appointment. This was in December.

    We are now over 3 months from when the problem was first recognized and the panels are not fixed. This is by far the worst customer service and the worst company I have ever worked with. I really just want these panels off and would choose another company because even and if the panels are fixed I would not expect things to get done if the panels have problems in the future.

    if I was just kept in the loop and it was looking that like you guys were trying to do something I would not have a problem but this is ridiculous.

    Very poor customer service.

    Moved into our new home 4 months ago with SunPower solar panels. We excited thinking our electric bill will be fairly low, but our electric bill was very high.

    We called SunPower for an explanation on how the system worked and why our electric bill was so high. Couldn't get a straight answer after a number of repeated calls. The standard line was "your system is functioning normally".

    After pointing out to them that their website shows power consumption and solar electricity generation numbers were not realistic, they schedule a tech to replace a part. They stated they would follow up in 24 hours to advise if the problem was resolved.

    Well almost two weeks later, I had to call them to find out what was going on. There response was "didn't you check the website to see if the number looked ok?"

    I'm not sure if the panels are working properly. Will have to wait and check the electric bill.

    If I could, I remove this crap and install a different system just from the bad customer support I've received.

    I wouldn't recommend this company to anyone.

    I've had a system of 10 Canadian Solar 250-watt panels connected to an SMA Sunny Boy inverter installed on my roof for 8 years. Production has steadily declined over that time (even though I was told by our installer that there is nothing wrong with the panels), and then last November we got a plug-in hybrid EV. Our electricity consumption when up more than we expected, and we have limited roof space for more solar panels. That led us to SunPower. Unfortunately I wasn't well educated about solar technology and the differences between manufacturers when I initially went solar, but now I know that all panels are not the same. We replaced the existing system with SunPower 327-watt panels and EnPhase microinverters in July, and couldn't be happier with SunPower's technology, warranty, and customer service.

    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.

    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.

    We had our 7.5Kw system installed just about a month ago. The panels look great and are producing as designed. Their monitoring app is easy to use and shows us everything we need to know out our system production/ usage daily, weekly, monthly and for the life of the system. So happy to be powering our house through solar.

    "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.

    I am very happy with my SunPower solar panels and equipment, they perform as advertised. They also look good on the roof with the invisimount installation. Their software system provides me with hourly, daily, monthly, yearly and life time production and also provides me with an emailed monthly report that shows my energy production for the month.

    We had a SunPower solar array installed by Positive Energy Solar late last year. It is working great. Our energy bill has been reduced by about 95%. I especially like the webpage they provided. It gives us up to the minute updates on the performance of our array.

    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. When I get calls back, they've done no prep, have no updates, and seem to be completely clueless about how solar is activated. It's pretty nuts. I feel like you'd really have to try hard to be this unhelpful. I would never recommend working with them.

    Best panels on the market with most complete warranty. The proof is in the warranty. The manufacturer stands behind their product and their dealer network.

    I have a broken solar panel. After about 4 months of me calling and following up, the panel finally came in. Then they couldn't find an installing company to install it...another 2 months. They came out and it was the wrong one! They found that there is another one broken. Supposedly got them on order...I've called probably 6 more times and every time they tell me they're on order. This time they tell me they aren't even ORDERED YET!! Go with a different company...this one has no follow through and could care less about their customers!!!

    I had Sunpower install solar on to a new home build in May '17. I moved in the middle of June '17 and turned in my paperwork on July 10th, 2017. Today is December 8th and I still do not have operating solar. I have had to turn in the same paperwork 3 times, all with the same information on it. I can't comment on the Value or Quality as I have not been able to see what those might be in 5 Months. Other homes had Solar installed 4 weeks ago and are operational. This is beyond ridiculous. UPDATE: Finally got the panels activated and received my first bill. Dropped the bill by about 45% which is great. I am happy now. Upgraded the rating.

    "Best panels with the best warranty "

    Reviewed Dec 01, 2017

    Just had 32 of their top panels 360-c-ac installed on 2 sections of my roof for 10kw. With many cloudy days my system reduced my first months bill by over 65% from $150 to $46. That is in just 3 weeks. With the 25 year warranty I expect to do quite well eventually. They cost more than most companies but the warranty was important to me. The main complaint I hsve is not being able to monitor performance at the panel level lkke I've seen other brands o#er.

    I was a little afraid to put panels on the front of my home looking at some of the ugly solar panels in my neighborhood, but I found it was time to do something because my utility bill was killing me. I decided to go with SunPower and I got their x21 335 black on black panels. I have to say they look absolutely incredible. I had a few of my neighbors even come over to my house and tell me how ugly they're panels look compared to mine. If you're putting the panels in the front of your home you can't go wrong with SunPower.

  • "Made in USA ? "

    Reviewed Mar 08, 2017

    Sunpower doesn't have manufacturing facilities in the USA. I got the information from 10-k filing report on February 17, 2017, and the link is here:http://investors.sunpower.com/sec.cfm
    "Our headquarters and research and development operations are located in California, and our manufacturing facilities are located in the Philippines, Malaysia, France, and Mexico."
    The reason for 4 stars is because of some dealer and some website says those panels as they are manufactured in the USA. Don't get me wrong are good solar panels, but are not made in USA and be ready to pay a premium price for their quality.

    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.
