Consumer Reviews of SunPower Solar panels
Our SunPower ground mounted, tower system (3 towers, 36 panels) will have been in place for 4 full years in just a few more weeks. We couldn't be more happy! Although we have seen a slight decrease in generation this year that has been solely weather related (tons of rain) and we are still generating all of our electricity usage! In 4 years we have had zero problems with the system and on the two occasions that I had questions our top notch Solar installer (ETM Solar) was right there with answers and assistance. Our only regret is that we didn't install the system years earlier!!... read more
We were extremely disappointed to find that after spending $50K on solar, SunPower initially did NOT deliver the all black panels that you show in all your ads. Instead, you delivered newer, slightly more efficient panels, with a white grid, that do not have the black, clean look of what you show in almost 100% of your marketing and advertising. The local dealer was helpful in swapping them out but the entire situation never should have happened. SunPower (corp - not your local dealers) is not being honest in it's advertising when you show one thing and deliver another panel that looks not as clean. If the newer panels are your new standard, then THAT is what you need to show in all your advertising. Additionally, we'd asked for a system that would get us to net $0 but we're still paying PG&E $100/mo and an annual payment of $1200 on top of that. To get the system properly sized, we'd need to spend another $3K to buy 2 more panels (and no, not just to compensate for the change in 6 panels which are slightly less efficient).

-Bought a large system from Sunpower in 2010. Was very happy with the product, installation, etc. Had some minor issues with the monitoring. They were quick to help me fix it remotely.
-Then I had a significant problem in 2017...lost over 1/3 of my production in April right before the summer season. I called Sunpower before they noticed production was down. They will often call after 2 weeks of a noticeable difference.
-They told me they would get it fixed usually within 90 days which was discouraging as that is the entire summer season.
-Long story short, it is 7 months later and still not fixed after me calling every few weeks for updates, progress, status. EVERY call I made they told me we will escalate this situation. It took them 6 months just to fix the monitoring system. Finally that is done. I have asked for a supervisor to call. All I get is customer service people who tell me the same thing over and over again...we know the problem, our team is reviewing it, we will get back to you in 3-5 business days.

Sunpower Solar Panel Summary
The Sunpower X series of monocrystalline panels are the most efficient solar panels used widely in residential solar installations in America with their X21-345 panel claiming an impressive 21.5% average panel efficiency. They also make an E Series of monocrystalline panels in the range of 320 to 327 watts that also offer an impressive maximum efficiency of 20.4%.
Sunpower also has a range of polycrystalline solar panels (not surprisingly known as the P Series) that have efficiencies much closer to industry averages of around 17%. They tend to market these to cost sensitive commercial and utility scale customers. Sunpower’s X series of solar panels are clearly the best solar panels on the market both in terms of efficiency and in terms of temperature coefficient.

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.

SunPower workmanship gets a “F” grade, AGAIN. Recently SunPower came out to replace all the microinverters that were failing one by one – our system is less than 2 years old. After they completed the work, we inspected the roof for damage (SunPower has damaged our roof in the past). We were shocked to discover footprints all over our 21 panels – 48 footprints to be specific! The way the panels are laid out on our roof, there was no need to ever walk on them. Walking on panels can cause microcracks in the solar cells, reducing panel performance, which will continue to worsen over time. The microcrack problem is a known issue that is even documented on SunPower websites and SunPower Facebook pages. Here is a quote from SunPower “We do not recommend that anyone walk on the panels because it can damage the cells, which would damage performance”.
After discovering our panels had been thoroughly walked on by the SunPower crew, we called both the SunPower corporate and SunPower regional offices a week ago. However we were only able to leave voicemails since no one answers the phone at either location. No one has returned our calls.
Our previous experiences with SunPower:
Initial installation – damage to the roof and the roof leaked at the panel mounting brackets. SunPower did then come and remove the panels while the roof was fixed, and then SunPower reinstalled the panels.
Reinstallation of panels – SunPower failed to connect 2 of the 21 panels. On our smart phone SunPower application, we kept getting error messages concerning slow data reporting. We kept contacting SunPower about it. After FIVE months SunPower figured out that 2 panels were not reporting, not connected, and therefore producing no power for 5 months.
Data reporting issues resume – Again we noticed this on our smart phone application and informed SunPower. Eventually they diagnosed that the microinverters were failing, which was causing production loss. 1 1/2 months after we notified SunPower of the issue, they replaced all the microinverters and walked all over the panels.
Apparently diagnosing microcracks on installed panels is not a simple thing, and production loss from microcracks will be small at first, but increase over time. So far since SunPower walked on our panels, production on our panels is down 6% over the previous year time period. While it is possible that this weather related, we think it is more probable that this is from 48 footprints of damage.... read more

We live in Southern California and signed a lease with SunPower through a local installation company. We liked our installation company, but since installation 3 years ago, our system has been down 5-6 times (and even though the system is connected to the internet it does NOT notify you or them when it is down, so several times it had already been down for a week when my husband happened to be in the garage and notice there was an error message). It has been down over 10% of the time that it has been on our roof. While initially our local company/installation company handled our repairs, it has broken so many times (including replacing the inverter twice and replacing all the panels), that they say they can no longer handle our repairs and we are now being referred to the parent company, SunPower.
Unfortunately, SunPower is unresponsive and has zero customer service. Our system most recently has been down for over 30 days, we have called multiple times and been told we are on their "high priority list." Heaven help those not on the high priority list, because even that took 3 weeks to get a team out to even look at it. It has been 10 days since then and we still had not heard anything from SunPower. We are currently paying $160/month for a solar system that doesn't work, on top of exorbitant SDG&E prices because our solar system is down in the middle of summer. We finally got a call back after multiple calls and emails over 10 days, just to be told they still haven't received a report from the technicians, they don't know what the problem is and they don't have an ETA to fix it. They said "maybe" 2-4 weeks to finalize the report and determine the issue and then they can start planning a repair - this would mean our system will be down for 6-8 weeks by the time they even TRY to fix it.
The lease provides a guarantee that SunPower will reimburse for any underproduction at the end of the year. It sounded like a great guarantee when we signed the lease. Here's the catch: they reimburse at the lowest cost of electricity (tier 1 currently $0.14 per kW) and when your solar panels are not working or are significantly underproducing the issue is not the tier 1 charges, but the tier 3 charges (currently $0.55 per kW). With this summer having heat in the 100s and our panels out we have had two $500-$1000 electric bills that would have been significantly lower had our panels been producing and the charges had stayed in tier 1 and tier 2 levels. The $200-300 we will get in exchange at tier 1 rates does not really make up for the underproduction. SunPower should install products that properly work and maintain them so they do not need to utilize the guarantee or should reimburse at the tier 3 levels.
I do not recommend signing a lease with SunPower. They do not stand behind their product, they refuse to make repairs on the system we are paying to lease. Find a different solar leasing company that stands behind their product.
UPDATE 9/19/18: They finally fixed our system - it was down for almost 2 months before they fixed it. Given the number of breakdowns, two inverter replacements and replacement of all the panels, we requested a provision added to the lease regarding expectations on timeline for repairs and possible termination of lease if they do not meet these expectations (not an unreasonable request given our experience with them). They refused stating "there is no provision in your lease to terminate due to equipment failure...SunPower will not provide any further consideration relative to termination of your lease" So just FYI thats how much they stand behind their products.... read more
This is the worst choice I have ever made for my family, I was told I would save tons of money by some con artist who knocked on my door in a sunpower shirt. First after waiting 6-7 months for them to install it (which I'm not upset about I know it takes awhile) less than 20 days after my install my inverter on one of my boxes breaks, and now im only producing half of what I should be, I get my electric bill and its 170 dollars on top of the 160 I owe SUNPOWER so now instead of paying one bill im paying two!! Which is actually costing me more now!! Then after waiting 30-45 minutes for someone to pick up the damn phone they tell me they are looking into it and that's all they can do. Now im hearing it may take months to fix....so im stuck paying two pretty big bills....they tell me that on my yearly anniversary if the system didn't produce what they said it would which is an average of 42kw a day they would refund me any money I had to spend extra....seeing as on a good day (which was the 19 days I had it before it broke) I was bring in 55kw a day they could literally not fix my unit for 3-4 months and not pay me a damn dime and id be up creek without a paddle.

All, I chose SunPower solar system due to their advertised technology, efficiency and warranty. I bought a system with 18 panels with microinverters even though the system was more expensive that 4 other consulted competitors. After 12 months of usage the microinverters started failing. The installer Photon Brothers in Grover Beach CA have attended diligently my complains and have changed more than half of the 18 microinverters in 2.5 years. Up this point the microinverters keep failing as well as the monitor system and no real long lasting solution has been proposed by SunPower. I am aware that I am not the only customer with this problem and most likely a class action law suit will result from this issue. In conclusion, there are many other options you could pick from and simply avoid SunPower at all cost. And if you currently have a SunPower solar system, monitor closely or demand to be allowed to monitor the panels twice a week and you may find out that you are on the same situation as me and many others....

My system was installed in 2007, three years later the SunPower inverter was recalled and was replaced, then 7 yrs later that inverter quit working. The company contracted to service SunPower products evaluated the system and spent hrs on the phone with SunPower trouble shooting and finally concluded that the inverter needed to be replaced while it was still under warranty. However, a rep in The Philippines decided that it was not under the warranty. After 4 calls I reached the Phillipino's supervisor who argued that it had been more than 10 yrs since the system was installed. I reminder her that the 2nd inverter was still under the 10 yr warranty by three years. Being consistent with almost all other SunPower customer service online reviews her rudeness was startling disappointing, but consistent with the apparent SunPower employee mission statement: "Let's not be helpful." Then I called her supervisor 6 times with no response or message. Another phone call later I was placed on hold for 26 minutes while her supervisor was attempted to be reached. No success! No surprise there! Then a phone call from a rep in Austin, TX. Same poor customer service with an admitted unwillingness to stand behind the faulty products SunPower sells because "SunPower doesn't manufacture the inverters and the manufacturer won't honor the warranty." Even though SunPower sold the faulty product as part of their system they will not help the consumer that they sold the product to.
In summary SunPower has a top to bottom customer service attitude of don't return phone calls to customers, DO NOT be helpful, and offer excuses that SunPower is not responsible for faulty products that SunPower promotes & sells because SunPower doesn't manufacture them.
Avoid this company at all costs!!!!!... read more

Perhaps all solar companies do the same things but my experience was with SunPower Corporate.
1. If you purchase system beware of purported guarantees. You will get a performance sheet of annual output that will be called a guaranteed production. It is not that at all. Rather, it is an ESTIMATE of production at the most optimistic conditions possible, which likely will never be met. When your system produces much less than the spec sheet you will be told it was the weather conditions. Yeah. It does get cloudy so why give you such an optimistic performance sheet with NO EXPLANATION or qualifiers regarding the numbers. Completely misleading.
2. Don't be fooled. THERE IS NO MONITORING WHATSOEVER IF YOU BUY THE SYSTEM. (don't know about other purchases). There is a software system that will indicate production but no one at SunPower actually monitors the software to see if the system is working. You need to monitor yourself and call SunPower if you see a problem. Here, not just misleading but fraudulent. There system is like a home alarm that the central company does nothing to monitor. When your local alarm rings that is the monitoring and you have to call the company. That is the SunPower system and that is not MONITORING at all.
3. Service is horrible. Follow-up is worse. Don't expect much and you will be rewarded.... read more

SunPower does not many venders in the state of Florida. I believe they don't offer good enough incentives for ventures to service their systems. I heard they offer some sort of credit point systems for handling warranty issues which is not advantageous for the venders to have a large stockpile of credits. Also, one of my inverter disconnects went out and even though it was under warranty I had a hard time going through the replacement process.

We have a large SunPower array -- 40+ panels. Signature Black 335s. What we like: the aesthetics, high efficiency, and productivity. The panels have performed as expected and after a year of service there is little sign of degradation.
What we really don't like: we opted for SunPower largely for the aesthetics of the black-on-black panels. Several of the panels in our array have a different sheen than the other panels. It isn't apparent in full sun, but when the light is diffuse -- cloudy days, for instance -- those panels looks noticeably different than the other panels.
SunPower replaced some of the panels to fix this problem under warranty - kudos to them for trying. But even some of the replacement panels have the same problem.
So if you are buying SunPower with the expectation of having a beautiful array (which we were, since they right on the front of our house and easy to see), beware that you may not get exactly what you hope for. While the panels look great in full sun, the manufacturing defects become apparent in ambient light.... read more

Horrible Service and Support
Type: Other
Reviewed: 09/10/2014
We purchased our solar system through our builder - Meritage Homes. Sunpower subs its contract work to local installers. Initial system installed was wrong type of inverter - Had to take time off of work for their product swap. Post installation I had to constantly call to get the service operational. Installer came but took the wrong paperwork, left our home after another day of work taken off promising to call us to reschedule. Days went by, nobody would call, multiple phone calls to Sunpower and they finally told me to turn the system online.
After turning online, nothing happened, their installers FAILED to test if it was even hooked up, Sunpower rep stated they must have forgotten the disconnect in the attic. Another week of no service and multiple phone calls, finally got the installer here, mind you they were working in our development the whole time but couldn't be bothered to call us or stop by. After an hour they determined it was a pinched wire - had they checked the system when it was installed they would have seen no power. System is finally online almost 30 days after installation. It worked for a total of 4 days before I came home to their system off again - no power.
Called Sunpower repair line who couldn't find my serial number in their system, because unless you pay for their monitoring station which is the only way to even see what your system is producing power wise, they don't register the systems. After an hour of speaking to a foreign individual they told me the installers would have to fix.
10 days later, multiple phone calls, texts to the sales rep, calls to the installer, they haven't even bothered to schedule an appointment to repair their equipment.
$14,000 for a 10 panel system, and all we have experienced is faulty wiring, defective products, and countless promises of return phone calls or scheduling of an appointment but they do not follow through with anything.
I have lost an entire month and a half of solar power in peak summer temperatures, 3 days of lost work, 4 hours of phone calls, and zero response from the company except empty promises. I have never in my life experienced such poor customer service and lack of any customer loyalty or interest in servicing their equipment. They are a scam once they have their money they have no obligation to repair or replace any service in any time period.
Their website support chat is useless, it is likely outsourced overseas, the person I chatted with today who took forever to respond used the phrase "query" which is common with Indian tech support companies. Their service technical support when you call them knows nothing about the products or how to schedule service calls.
The worst part is without a monitoring system I have no means to watch what my system is doing, and after this many failed attempts at even getting operational, I question whether it is even hooked up properly to offset my own power usage. When the system was "on" I noticed zero decrease in energy usage at my bi-directional meter, and the technical support reps don't know how it's supposed to work or how to check if it is working.
I would not recommend this company to anyone looking for a quality product, or quality support, you will not receive it from Sunpower, so save your money and buy a paperweight instead, it's about as useful as our system is on our home and absolutely no end in sight for repair or quality of service even if the magic green light is ever to come online again.
Mind you, I have been assured the entire sales management, customer service management and support management are aware of my issues for over a week now, and even as of today, nobody has even bothered to call the installer to have them come and even look at our system. They themselves take weeks to get back in touch with people if ever at all, so a terrible company with Sunpower and just as poor with their subcontractors.... read more
