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.
