SunPower offers three different payment options for customers to choose from that help them save on their electric bill: solar leasing, purchasing with cash, and financing with a loan.
With the lease option, SunPower Capital owns the system and the customer effectively rents the system via monthly payments. The lease comes with a 25-year performance guarantee, as well as easy options in case the customer needs to transfer the lease.
SunPower also offers outright purchase and financing options for customers interested in the tax credits and other incentives that supplement the benefits of solar power ownership. Loan terms for solar systems typically range from 5 to 25 years and do not have any prepayment penalties attached.
The cost of a SunPower solar system ultimately depends on several factors, including current energy usage, available amount of unshaded roof space, the local utility’s net metering policy, and other factors. The easiest way to learn exactly how much solar will cost you is to obtain a free quote from SunPower.
SunPower has been on the cutting edge of solar technology for more than 30 years. Consequently, the company excels when it comes to innovation and design of solar cell equipment, enabling customers to be confident that they will have the highest-quality solar products expertly installed on their homes.
In fact, the solar installer provides the highest-efficiency solar panels you can buy today. The solar panel manufacturer engineers elite solar modules that are up to 22.3 percent in solar panel efficiency, and carry a temperature coefficient of -0.29, meaning output will not be negatively effected because of excessive heat. Each SunPower panel is made of anti-reflective glass and coated with anti-reflective film for optimum durability and to ensure that they capture as much sunlight as possible. In short, SunPower cells provide the best value for your money.
The SunPower X Series solar panels excel in terms of power generation and deliver 44 percent more energy per watt than competitive products. This means that SunPower can provide more clean power for its customers' homes with a smaller solar installation and fewer panels than other companies.
Every SunPower solar panel also boast 75 percent more energy per watt than conventional solar panels, meaning that an investment in a SunPower solar energy system pays off significantly more in the long run.
In addition, SunPower panels maintain their energy production much better than conventional panels in partially shaded conditions, making them a better rooftop solar option for customers who live in a cloudy region or an often shady area.
In addition to being highly efficient, SunPower panels are uniquely attractive and aesthetically pleasing. While many other companies in the solar industry offer conventional solar panels — traditional blue photovoltaic panels with bright, visible frames and mounting hardware — SunPower's panels are all black, and their mounting system sleek and nearly invisible, allowing the SunPower solar installation to blend in better with the rooftop on most homes.
SunPower recently introduced SunVault™ storage — a powerful and sleek residential storage solution that pairs with SunPower Equinox®, the company’s premier residential solar power system. Once widely available, SunPower panels that are installed with SunVault storage will allow customers to have ready access to electricity even in the event of a power outage.
Monitoring of system status and performance is extremely important for customers who want to see how much energy the panels on their roof are producing —currently, as well as historically — and ensure that everything is operating as it should.
SunPower provides a helpful, convenient app for customers to do just that. The app provides important system information such as power output, estimated savings, energy production over time, and the environmental impact of the energy generated by the system. All of this system information is easily viewed on a smartphone.
SunPower systems also include a consumption monitoring kit, which is installed if the homeowner’s site is compatible. With consumption monitoring, homeowners can view current and historical energy usage, and the SunPower app provides more in-depth information about their energy profile.
SunPower offers multiple warranties to protect its customers' solar energy systems, including a 25-year Complete Confidence product warranty, which covers the equipment itself, and a 25-year workmanship warranty, which covers the labor and solar installation. The clean energy company also offers a 25-year performance warranty, which covers the customer in the event that their solar modules underperform in terms of energy production and output.
Many customers may be interested in obtaining a SunPower module through a Power Purchase Agreement (PPA) because this payment method typically includes some kind of $0 down option, which eliminates a barrier to entry for them to go solar.
Unfortunately, SunPower only offers PPAs to commercial customers; however, the company's solar lease option can provide immediate financial benefits (and at a flat rate) to customers.
Some users on our site have provided negative feedback with regard to SunPower's customer service. Common complaints include difficulty to reach a representative, delays in returning phone calls and inability to resolve issues.

I purchased my solar electrical system through POCO Solar and completed the entire system 4 years ago. At that time, PG&E limited size of the system, but that was increased by petition to PG&E. SunPower solar panels are technologically superior, and have a higher output per square foot than other companies I compared. My system has 21 panels, roof mounted, and a wall mounted inverter. My home is two story and includes a large pool and hot tub. The contract included a OUTPUT guaranty as well as the 25 year warranty - all through Sun Power and POCO Solar at no additional cost. The POCO Solar sales person wexplained everything in great detail and all payment options were presented. The installed system is continuously monitored by Sun Power and myself to guaranty performance and identify any problems. All system maintenance, if any, is handled by POCO Solar. My electric bill for the entire year is between -(minus) $ 20 to - minus $60. The entire contract was completed as scheduled and on time. I have had no system or equipment failures.
I purchased my SunPower system over a year ago and have had no problems since the system installation. My electricity bill has been reduced to about $25.00 a month. Many of my neighbors with equal home size have twice the number of panels my system has. SunPower panels are very efficient and have a 25 year warranty. Easily one of the best systems out there.
I had an incredible experience with SunPower. They worked with me to figure out how many panels I needed and kept me informed on every step and completed each step as outlined and met with the inspector on each inspection. They got my work done from start to finish under a month. I love the 25 year warranty. This was an EXCELLENT experience from start to finish and great follow up on explaining my SCE bills and follow up to make sure I was getting everything I was expecting. This could not have been any better.
I have had a SunPower Solar system for over 14 years and it is still going strong. We have never had any problems whatsoever. I strongly recommend this company.
BUYER BEWARE !! Worst customer service ever. If you have a problem they don't care, they just want your hard earned $. They spend a lot of time and money on fancy websites making false promises. Go with a local company and do your research. Look at the BBB reviews of SUN POWER. 86% are negative.
They appear to make the best solar panel with the best warranty. We have had them more than 2 months, and so far so good.
Absolute worse decision I made was going with this company. I was led to believe that they would monitor things. When my system had been down for a bit, I called and asked about the monitoring and was told it was a "shared responsibility". Meaning, if the customer doesn't watch this everyday and the system goes down, the customer gets screwed. Customer service is terrible - absolutely no accountability and the communication is not much better.

This is my second property that SunPower installed the solar system. No hidden thing, I am happy with the system production although I still have to pay a few $$ for electricity to PG & E. SunPower also provided a rebate refund $1000 for being a Triple A member. SunPower's contracted installer also applied the $2421 San Francisco City reward. I received both rebate funds.
Works well, looks good, less panels then the others.
Best solar panels and warranty! Very clean looking installation.
I install a 17 panel, 5.86 kW (DC), 5.13 kW (AC), system. We decided to go for SunPower because their system needs less panel, but produce more power than other vendors' systems. Last Aug/Sept, we have no guilt to turn on the AC 24/7 daily. I used to pay $300ish for my power bill. I am going to break even in 5 years.
It was great.. They paid ME about $1000 to install it [4 years ago,lease] -it produces 97% of our total household energy needs [inc hvac, hot water, stove, cars, etc] and saves us about $250/mo. No equipment failures after 4 years -it just silently does its job. Biggest no-brainer of my life.
I am a leasee of a Sun Power lease and have been happy with them over the past one year of lease. I feel my product is excellent and an excellent warranty.. I have had only superior customer service and would highly recommend to anyone who wants a solar lease.
Worst company to deal with . Got my panels from Sunpro in Wildomar Ca. I explained that I needed enough power to operate 2 additional washers and dryers and a spa. I have to pay $800+ to Edison every end of the year. I was promised that I would probably pay 12-22 dollars at the end of the year. My system does not produce enough and I cant get Sunpower to help me anymore. They sent out 2 additional panels and the installer told me it would not make any difference because I needed at least 6 more to compensate for what I needed. I wish I could have them come get their stupid panels and go with a company that is honest. DO NOT GO WITH SUNPRO IN WILDOMAR CALIFORNIA. They are rude and lie to you.
Sunpower Co. installed my panels a few years ago. Installation was quick and informative. System has worked great and saved many dollars. Staff is friendly and efficient. Recommended this business to others and they are completely satisfied, recommend to anybody.
Our 1st year anniversary just passed, very, please. The power calculations, and performance of the panels, provided 100% of our usage from August 2016 to July of 2017. Actually, we overproduced by 300 Kwh. (Which I don't recommend, having a system larger than usage, not cost-effective.) Installation went as planned, very professional. No Leaks, Northern Cal had a very wet 16/17 winter. We lost internet service for 1 day and was contacted by SunPower since they could not see the power generated. 25 year warranty Parts & Labor.
I have had Sunpower solar panels for 5 years. They guarantee production for my panels. If production is less than the guarantee, no questions asked they provide a refund check for the difference. I have had great customer service for any issues both from the front office and the repair person.
had baker elec install system old bill was 850 950 month leased system during install they almost burned down house by putting ground into hot metrics's box roof leaked they had me sign release pulled panels new roof re grouped panels lots of problems very unhappy any good lawyers out there 77 old dumb guy would like to have them put it were the sun doesn't shine
Sun Power installed my 12 panel 3.9 KW system 2 years ago. They designed the needed KW system perfectly and the net metering system has resulted in an electric cost of $10/month (the amount required to stay connected to the grid). I am saving $150/month which, as power costs increase, will recoup my total costs over 6 years at which time I will have free electric power. I like being my own power company!!
Worst customer service I've ever encountered.

Research has indicated thatvSun Power Solar Panels are the best in the industry. Company who installed panels did a reasonably good job. However, before the end of the first year of service, had to call to get system down resolved. This occured 3 times over 4 month and replaced one inverter twice.. Finally had to completely rewire my panels and replace one inverter twice. Since then, have had flawless operation. Sun Power panels have provided 100% of my power for 4 years. Installer has went though Capter 11 and service has since degraded. Not happy with installers support since filing Chapter 11.
Sun Power installed the panels for our home - work was well done and on schedule. Had some minor technical issues that were quickly fixed - great monitoring system.

We have a SunPower system installed on our home. The terms, installation, performance and aesthetic of our system has been fantastic. Our system is the right size and the components installed are tidy and hidden as best as possible. We have had our system installed for 2 summers now and it has delivered flawlessly. Our system was installed by Photon Brothers and from sales person to installer and those on the phone have provided A+ service and have answered my questions promptly. Our thoughts on this installation and service are that if the system runs flawlessly, there will be no other interaction with either SunPower or Photon Bros., becasue all components are operating as intended. The monthly reports and online monitoring are pretty cool too.
They did a detailed on site analysis and did not try to sell me more panels than my roof and the shading trees would allow.
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!!!!!
Working great. However, far more expensive than others I have heard about. 20 years is a long time to lease, especially for older homeowners. Does not offer to negotiate the lease to make it more affordable.
Installed system on my home roof in Dec 2016. The system has worked as promised. The system is producing more energy than I use which is great. The online monitoring system is awesome. I like the USA made panels which have more watts per panel than the typical China made panels which means less panels on the roof. I would recommend the dealer I used. Lodi, CA.

I purchased my system, as it seemed to be the cheapest and most advantageous. I have 33 panels with an 11.8kwP potential output and based on the shade that comes from trees near me we get 10 with peak sun. Service has been excellent from installation to followup service with the monitoring platform. Best product we could find on the market, coupled with good service from installation to problem solving. Would recommend to anyone who needs or wants solar.
I talk to this company about my bill and question about the contract no one knows answer or they dont speak english well . wHEN YOU DO TALK TO SOMEONE THAT SPEAKS ENGLISH THEY SAY ARE YOU STUPID DID U READY YOUR CONTRACT GO BACK TO SCHOOL. PLEASE NO ONE SIGN UP WITH THIS COMPANY I WISH I NEVER DID
My system was installed and operating on June 30, 2017 as promissed. The installation was in conjunction with my house being re-roofed. The Energy Plus Solar installers contacted the roofing company and cordinated everything. The few hiccups with the city inspectors were all handled seemlessly and I was kept abreast of the progress. The Ron S. is my saleman and he has been awesome, great before and after the installation customer service, he handled everything for me. The electricity produced is higher than he told me it would be and we just got out first bill, $1.15. We paid for the system so I can't talk about financing or leasing. If I had to choose a product and installers again I would select Sunpower and Energy Plus Solar. I've been telling all my neighbors and my clients about my panels and my experience.
Customer service and accounting is shopped out to people in the Phillipines...and they do not have the same business mentality as American employees...too "robot like"...extremely difficult for them to get accounting issues resolved...it took almost a year to remove an erroneous finance charge from our account....$2.82 that was not a valid charge stayed on our account for 10 months...and the way their system is setup everytime we ordered materials the shipment would always get put on credit hold...the fact that these outsourced accounting people were like robots and couldn't grasp the concept of making sure customers receive their orders in a timely manner...completely unprofessional...leave messages and noboby calls back...send emails that get ignored...just horrible customer service
WE have had a great experience with SunPower!!! Pell is who they used for installation ...they did a fair job...broke more roof tiles then we would have liked but they reimbursed us for the damage. Customer service has been excellent anytime we have called our problem has been resolved pretty quick. Our monthly bill is what we were told no increases for anything else, and Edison only gets a couple bucks a month with our end of year bill under 300.00. all in all great experience..
This is long but worth the read! Very good information to be informed about in this Review. Be very careful in dealing with SunPower. I have elderly parents that live in a retirement community and live on a very tight fix income. SunPower made a proposal to their community to install Solar Power for all Common Community Buildings. The community voted against the installation due to the fact that SunPower was the only company making a presentation and most of the retired elderly did not understand how Solar Power could save them money. SunPower then was able to talk to individual home owners after their presentation and make their pitch on how they could save them money on their home electricity bill. My parents took the bait and started talks with SunPower. SunPower was trying to sell them on a No Money Down Lease solution for 20year at $100 a month. Their average bill is just a little higher than $100 now. The cost of the Solar System to buy was about $21,000 and the lease over the 20 years would come to just over $26,000. They directed them against buying the system due to their limited budget. My father mentioned to them that all their assets were tied up in a Living Trust and that I was the Executor of the Living Trust. Lucky for them and myself SunPower got greedy and said I would have to sign the Lease also. My parent called me up and asked me to sign this lease as the Executor of the Trust. At the time of the call I was very busy at work with multiple projects to attend to and did not think much of what they were asking me to do. They sent me a secured linked document to sign electronically. As I was going through the document I notice that is stated me as the Co-Leaser and not the Executor Of the Living Trust. This immediately caused me to have big concerns over who my parents were dealing with. I told my parents I could not sign this lease and needed a couple of days to look in to Solar Power. As always I am a person who researches everything to make sure I am getting what I am paying for. I contacted two other Solar Companies and asked them a multitude of questions and to give me quotes. After talking to both and getting some numbers both said they don't do leases and recommend that no one should get a lease with solar. Both gave a rough estimate of about the same price for the Solar Systems as SunPower. But with further review neither could save my parents any money on their electrical bill due to they don't use enough and that they were getting a medical discount already on their utility bill. I then started having my parents ask questions to SunPower why I had to be on the lease, what was the purchase price of the Solar System, and do they have a loan program. SunPower then started dancing around the lease saying I did not have to sign it. They presented the Purchase price of $21,000 with the FED Tax credit of 1/3 the coast which brought the price of the unit to about $15,000 after the Tax Credits. They also gave us the terms on the loan but did not include the tax credit. The loan was also very strange that they mention that there were terms to the loan. I had to read the fine print to understand that you had to pay at least 1/3 of the system off in 18 months to keep the payments the same. If you did not pay 1/3 off your loan off interest and payments would go up. We immediately wrote them and cancel any further discussion with them. SunPower had the nerve to try and charge my parents $250 for coming out to their house and to put together a proposal. I replied to their email and told them I would sue them if they did not decease talking to my parents and trying to collect $250 for the so called services. They wrote back and stated they were doing everything in good faith and that my parents should pay them the $250 but in a round about way they would no try to collect. Since it was very vague I wrote back and confirmed that they would not be charging or talking to my parents again. They finally responded that they would not. Conclusion: SunPower Lease - $26,000 Product cost $21,000 1/3 Tax Credit would go to SunPower total cost of Solar $32,600. SunPower would make $15,000 on this type of deal. SunPower Loan - Product cost $21,000 1/3 Tax Credit was not mentioned interest range from 3.99 -4.99% and 1/3 of the had to be paid off in 18 months or loan would go up and interest could change. Very Unclear terms. Last this system would not have met my parents ultimate needs to be able to us more electricity like they would want to and keep their electric bill at $100 a month. SunPower works with Authorized Installers which could create big problems if the system does not do or work as they claim. The two separate companies could blame the other and you will be stuck in the middle. With a lease you can not include the Solar Upgrade to the Price of the house and the new owner will have to agree to the lease. If the new owners don't agree to the lease it can be remove AT A COST of the Lessee. Lastly SunPower could also put a lean on the house at the time of sale making it difficult to sell the house. Recommend: Horizon Solar Power was very helpful and I believe honest. Their company does not do leases, they will give you 100% guaranty if your numbers calculate out and they install their own products so there is not middle man. You Deal with One Company that is honest.
after 4 years was told my system was not under warranty for the 20 years like d by installers and company. had a panel shatter on inside, would not cover.
Service is excellent. They kept me informed as we covered each step on installation and permitting. Regarding financing, I got a 10-yr loan that was almost the same monthly payment as my former electric bill. Service since installation is great (2 yrs in service). They are watching the performance. The communications module had some problems, but they were on top of reporting it and fixing it. No complaints.
2 inverter and 24 solar panel start on may 2016. One inverter with 12 solar panel stop working before Christmas 2016, already 7 months and still out of order ( Sun power have no service, for service by 3 party technician waiting 10 to 15 days. After each service solar working 2 to 3 days and again coming error ( not working). Already replaced inverter and still not working. Last error on this replaced inverter start June 22/2017, until now nothing done. Sun power not monitoring working units. Customer service is terrible. Supervisor Mabel is giving empty promises. July 25/2017 customer service call me to conform appointment of technician on August 10/2017 time 11:00am 2:00pm, so home owner need to be at home ( problem for working owners). This time will come Sun power technician, nice and waiting time only 50 days. I stop billing collection.
Our panels (see yourself at https://goo.gl/mYVzbf) were designed and installed by RevoluSun, an Elite SunPower dealer. These 29 X21-345 panels are a 10 kW system, and we've actually pinned generation up against the SolarEdge Inverter limit of 10.3 kW once or twice. (See https://goo.gl/nbrWNr.) RevoluSun was perfect. Our biggest problem was getting building and electrical approvals in Westwood, MA, a bunch of really conservative people. Amazingly, RevoluSun/SunPower were the only team that were willing to work with what we wanted. We have a moderate tree shading situation, and we are not going to cut trees. So the plan was to OVERBUILD, that is, put up more nameplate generation than we needed, because when we did get clear sky unshaded sun, we wanted to generate like crazy. Sungevity (now bankrupt) wouldn't even consider our home, even if we were going to own the panels. SolarCity wouldn't do the full 10 kW. SunEdison (also bankrupt) came closest to RevoluSun/SunPower, but was only willing to put up 8 kW. Two other suppliers were rejected for other reasons having to do with their process. First Light occurred on 31 December 2015. And we've never looked back. Meantime, RevoluSun has been a fabulous partner and I cannot speak too highly of these marvelous panels.
I love the SUNPOWER X-22-360 solar panel. The panels are probably the best in the business, I`m very happy with them. The installation company that's where a problem may occur, like with me. Make sure you double and triple check and choose the right installation company.
Sun Solar serviced my solar panels, when I required work on my roof. They were on-time, efficient and quick to do their job. Highly recommend Sun Solar of Anaheim, CA.
This company is SCREWING us. The solar panels were installed two years ago at my parents' house. After the first year they received a bill from Edison for over $1,000 for electricity usage. This prompted SunPower to come back to the house and install an additional 14 solar panels. Year two just passed in April of 2017 and they received another Edison bill of $1,200. (Electricity usage has remained relatively constant over the last three years. We've actually been consuming less electricity in the last few months due to the purchase of energy efficient appliances and lights and are still paying more than before we had solar panels.) I finally got involved in February 2017 as they kept brushing my parents off. After my own analysis I realized they tricked my parents into a signing a contract that stated they paid on average of $284.20. THIS IS FALSE. The average bill pre-solar was $160 in the summer and $173 in the winter. No one in their right mind would knowingly agree to pay $153 for a solar lease that only covers 50.4% of electrical consumption when the average bill was ~$166. Page 1 states that the estimated savings from Edison would be $175. How is that the savings if they never paid that much in the past? Now my parents are paying on average $100 more per month with solar panels and they are refusing to offer a fix. To make matters worse we just had a third party engineer come by to confirm if the solar panels were producing enough energy and it turns out the additional 14 were never connected (still aren't and they have been on the roof for over a year) and their installation caused leaks in our roof that has been creating water damage in our attic for the last year. Still fighting this and currently looking into legal counsel to get these panels removed from our house.
The most intelligent and courteous personnel.
Great panels and great company! I spoke with many and after listing to all the other companies shoot at each other in criticizing all the competitors, many of which actually handled Sunpower panels themselves, I went with the panel and the dealer who made the presentation that remained the most professional and provided me with the best communications! I love my system! I used a well reviewed company called Solar Concepts! A PHENOMINAL TEAM!

In my fourth year with Sun Power and it has cost me an average of $120.00 p/month more then I paid Southern California Edison before SOLAR.
SYSTEM WORKS FINE.CUSTOMER SERVICE PEOPLE ARE NOT THAT SMART!!!! I DON'T LIKE THE BILLING DEPT. ATTITUDE
Reading down the recent reviews, I have to conclude that it's all about your local installer. Sunpower is a vertically integrated operation--you can't buy the parts and do it yourself. You have to contract with a Sunpower approved installer. In my case the installers were reasonably good. However, today both of them have gone on to other things. That suggests a problem within the corporation. My (nominally 2KW) system was turned on 6 years ago (June 16, 2011). Over that period of time it has produced about 200 KWH more than I have used. The remote monitor readout quit years ago, but it was totally superfluous anyway, so I have never bothered to get it fixed. After months of use here in Azusa, CA, I decided to spring for a Sunpower installation for my mother in Sierra Vista, AZ. Our experience there is similar to here; the panels and inverter seem to be rock solid and output seems to be as represented.
Customer service stinks if you call the 800 number. My local dealer did a very good job answering questions. They were great and made me feel at ease.
From the time we signed on the dotted line to the installation, everything ran so smoothly. The salesman was the best and still continues to check up on us.
Customer Service is one of the worst I have dealt with. When I called because my system isn't reporting the lady claimed it was caused because of the electrical storm (which we had not had an electrical storm) I told her numerous times we had no storms but she didn't listen. I've called 5 times, still waiting for someone to fix the issue. No idea if my system I producing like they said it would be. I was told when they were trying to get me to sign the contract that they also monitor the systems and would be able to tell if something wasn't working correctly right away. Guess that was a lie, they do not monitor the systems, its up to me to check it daily. Would not recommend Sun Power to anyone. Worst customer service once you sign
Have had the system install and producing since March of 2012. I have kept month by month records since I have lived in the house. Central California is hot in the summer and my average monthly bill prior to the installation was $393 (that was over a 5 year period). After the installation the average cost per month was $110 a month.
I have a 22 panel system which provided 180% of our electrical needs last billing cycle. We got a $117 credit from SCE! Installation was done last July with some minor hiccups by a Sunpower crew. The install is one of the best I have seen. We monitor it daily and have had zero issues since going live. I would certainly recommend to all my friends.
