FRAUD - not refunding money for providing non functional system and not solving problem in reasonable timing
FRAUD - FAKE PROMISE AND EXPECTATION during proposal, 8 months to complete a simple solar installation, 1 year and multiple escalations and all the way to CEO to fix one simple issue.. 0 on customer service .. all employees including project manager are clueless on internal processes, no visibility or control on third party installers, don’t even know if the permit was filed.. not sure what CEO is Peter Faricy is up to? The whole organisation is hiding behind one sided contract which doesn’t protect customer against delay and damages …
timeline/time is of the essence, liquidated damages, direct/indirect damages etc.
May be we all should gather and file a class action lawsuits then only CEO Peter Faricy will wake up from sleep

SunPower Solar Panels
I actually purchased solar panels from this company about 12 or 13 years ago and I was very happy I did so they worked as expected and the company was a pleasure to work with, in fact so much so that I had 5 of my friends contact them, all of which purchased their own. Sadly this all changed with the company a couple of years ago. My unit was no longer producing the power it should. I contacted SunPower and almost a year later they resolved the problem. Yes I said that right almost a year. But that isn't even the worse of it, their technician who replaced the faulty unit created a problem with the electrical that caused the main breaker on my house to burn out. At the time I did not realize that, plus it was in the middle of summer here in Arizona, 100 plus degrees. The electrician that did fix the problem had to disconnect the solar panels to do so. This cost me over $1000, which I have been trying to collect for over 6 months now. The company just flat out refuses to work with you. They haven't denied it, which they can't, but they haven't reimbursed me either. Sadly I have spoken with two others that purchased the solar panels which have had problems to where they are unwilling to work with them as well. This company has gone, at least to me, as gone from a good customer service company to an extremely poor one. At this point if you are looking for solar panels, which I believe are a good investment, I would definitely look elsewhere.

Customer service is a joke to them
Customer service is a joke to them. I am 10 months of trying to get service to fix a system that produces 25% of what it is supposed to. After 1 visit from them my system still does not work and now I have broken roof tiles from it on top of that. The only time they came out was 3 months ago. I call them once a week and I'm about to call a lawyer since it's a lease and their equipment.

System not functioning properly job abandonment by SunPower by Precis
I telephoned Sun Power by Précis and made an agreement on November 22, 2019 to install a 18,467 kWh system for $44,733.60. Tim Marquez was the salesman representing SunPower by Précis.
As a retired contractor, I asked Mr. Marquez, if the installer's would be performing a load capacity test of my pool and pond pumps because I wanted to make sure that the system would off-set my energy's demand.
Mr. Marquez assured me that the installation team were professional's in the industry at sizing up solar systems. After paying off the 40 panels on our garage through Solar Max I wanted to be sure that the additional 36 panels by SunPower for a total of 76 panels would be sufficient to off-set my energy consumption and I made this clear to Mr. Marquez.
In fact, I invited Mr. Marquez to my backyard and showed Mr.Marquez the swimming pool and pond systems. Since
Mr. Marquez assured me that I would have at the most a 200 dollar a month bill or possibly no bill at all.
After installing the new system, I started getting SCE bills from $500-900 monthly.
After complaining several times to SunPower by Précis, over the past year, that the system was not functioning properly, I finally was able to get Précis technicians out to figure out why I am still getting $500-900 dollar a month SCE bills on top of a $400 dollar a month solar payment on a dysfunctional system .
The technician's said we were probably using too much power to off-set our SCE bill.
Then, I was told that some of the micro converters were not working and would have to be replaced.
When I telephoned SunPower by Précis to let them know that the new micro converters are still not working nor registering.
Fran from SunPower by Précis e-mailed me and explained that any further concern's with their Solar system would have to be addressed through Sun Power and that SunPower by Précis Solar would no longer be providing service to our system.
This abandonment and lack of accountability is unacceptable, unprofessional, and unlawful and has led to me having sleeplessness, anxiety, stress , and frustration being a disabled senior on a fixed income.
As a disabled senior on a fixed income, I will proceed to file complaints with the CSLB, the attorney's general's office through the State of California, The BBB, and yelp, as well as the financial institution that supports the financing for SunPower by Précis of this dysfunctional system.
My complaint is as follows:
1. Failure to fulfill the terms of our agreement (abandoning) service and maintenance of my system as per Fran's e-mail dated 01-11-2024.
2. Failure to take my daily kWh energy requirement and divide it by my peak sun hours to size up our system and then to divide the kW output by our panel's efficiency to get the estimated number of solar panels needed during the initial site inspection, and to access my homes unique attributes. This also contributed to SunPower by Precis 's underestimating my energy consumption for off-set.
3. Failure to use a multimeter to measure current, voltage, amps, and watts to my pool and pond pump equipment, as requested, prior to installation.
4. Failure of my Solar equipment not working properly or producing to their specifications.
This "failure to properly measure load capacities and installation of a dysfunctional system is negligence / Fraud , among other factors, this negligence has caused hardship, stress, and financial distress to me as a disabled senior woman on a fixed income.

My system has been inoperative 15+ months
My system has been dead since September of 2022. I have called SunPower 21 times since the system crashed. I've had 9 site visits from the tech that services the system at SunPower's request. The reports all say the same thing since the wall monitor in the garage was replaced. Nothing changes. SunPower continues to ask for the tech to make yet another useless site visit which only wastes more time.
In those 21 calls from me, I have been promised callbacks every time and every time they have ignored me and I have to call, again, to get any updates. My case has been escalated at least three times. How high can this continue, or, is it just an empty claim? Any new information, such as that I've gotten yet another case manager, is only obtained by me when I call in frustration, yet again! You are never allowed to call and speak to your own case manager, ever, and they never call you!
Through all this, I have to keep paying full price for electricity and continue paying my solar system loan payment.
Avoid this company! They have supposedly high ratings, elsewhere, but just look at all of the angry customers on just THIS site!
Perhaps I am too trusting and have waited too long for what I had originally thought was a company with customer service ethics. Maybe it's time for a Better Business Bureau contact and finding a legal company to help (and, of course, add to my costs!). I will also look into seeing if there is a state level office that handles such issues.

Failure to Deliver on Project
Note: This is a US review from Massachusetts, I was in Mexico when I wrote it.
I first contacted SunPower on 5/25/2023. Our contract was final-signed by SunPower on 6/5/2023. Since that time, we have had four project managers and we do not have any permits yet. We are 7.5 months into the project with nothing to show for it. We live in a HOA community. The municipal government won't issue permits without HOA approval. I have had to track down documents that were SunPower's responsibility to obtain. I am now missing only one document for HOA approval that SunPower has to provide. On December 6, 2023 I informed my SunPower Project Manage that the Certificate of Insurance that they provided was defective and required correction. As of today, January 8, 2024 I have still not received a corrected COI. I have terrible problems reaching my SunPower Project Manager. It takes her up to a month to answer an email. She doesn't follow up on anything in a timely fashion. She was unable to obtain a copy of the roof design, available from the municipality's building department. I obtained a copy of the roof design and submitted it to the HOA. I informed the project manager that i had obtained and submitted it. She apparently does not read my emails because she is still asking for the roof design on subsequent (infrequent) emails. SunPower has placed an emergency disconnect on an exterior wall for the system in the design (an appropriate design element). The HOA asked for documentation that the disconnect has to be installed on an outside wall. For a month, the Project manager "has not been able" to obtain the documentation. I called the building inspector today and obtained the information in less than 3 hours. Our project manager routinely drops the ball, does not respond to emails in a timely fashion, does not followthrough with the HOA or municipality, and is not moving the project forward. I am ready to cancel the contract, particularly in light of all of the negative customer service reviews on this site. If you have not yet signed a contract with SunPower I would strongly recommend that you reconsider.

Wish I could give negative rating.
Wish I could give negative rating.
I was forced into using them as part of my house build. They cost $22k.
The system has never worked properly- I got zero credits in my bill. After an immense amount of bouncing around in their service over the course of a year, it might be fixed - but I need to constantly check it and onus is on me to repeat the process if not.
I will be given no credits for a broken system.
Run to literally any other company. This product doesn’t do what it promises!

Hard to trust this company
I had an inverter issue so I called Sunpower to schedule someone to check it out. Was told someone would contact me and after 2 weeks no one had so I called again and was told again someone would contact me. Waited another week, no call so called them, was put on hold then told my inverter was out of warranty (apparently its 10 years on the inverter and I was out by a few months). Apparently no one thought to just tell me that on my first call.
Was then asked if I wanted to have someone call me back for service and was actually told it would be faster to seek out a 3rd party to repair it.
The best quote from their website "We’ve got you covered for 25 years, including performance, labor and parts.*" I guess not exactly if you dig deeper, "10 years for everything not on your roof (storage and monitoring)." funny how the word inverter is left out.
Do better
