I was so lost with monitoring my system!

I'd never checked monitoring after the installation years ago. I'm alone, have no help, figured I's better figure out how now. Couldn't sign on, my password had to be changed by the administrator--I panicked--HELP! Finally called SunPower and spoke to Ivan, my prince in shining armor! He calmed me, sent me a password-change link, then 1-2-3 and I was at my monitoring page. Thank you, Ivan, for helping me, and thank you SunPower for my solar panels.

Customer service

I asked Jansen about a number of things from solar panel maintenance to contract provisions and he responded to all of them quickly and thoroughly. I was very impressed and was relieved that I wasn’t referred to other departments for answers. I appreciate his knowledgeable yet personable attention!

Absolutely horrendous

Stay as far away from SunPower as you can, unless you like non-functioning systems, endless hold times on customer service, and refusal to have a tech come out to your house to even investigate why your system isn't producing energy. My solar system has not been producing energy for several months at the least, and maybe longer. I have called SunPower so many times and get nowhere with them. You're lucky if you can even get a human on the line after endless wait times. Once you do get a human on the line, they'll tell you that you need to contact one of their local dealers. Then you repeat the same exercise with the local dealers, explaining what's wrong, and they tell you you have to contact SunPower corporate to have them send a tech out. But SunPower corporate refuses to send a tech out. I have no choice now but to rip out this junk system from a junk company with junk customer service and replace it with Tesla or some other company that isn't falling apart at the seams. The wheels are coming off at SunPower. Stay as far away as you can. EDIT: They've requested more information from me as if my review isn't legitimate or something. Here is my reference number with their customer support: ref:_00D80ZF1L._5002T1OmjR8:ref Nothing I have said here is something I haven't said to them in private many times. But now that it is posted publicly they are scrambling to address it. We'll see. Haven't heard from them yet. EDIT 2: Do you see their response from January 30th? They never followed up after that. They told me they would send a technician out and never did, nor did they call me back to schedule one. EDIT 3: They finally sent a tech out to look at my system (which wasn't even installed correctly). They charged me $300 for this technician to come out. This was about a month ago, since then I've heard nothing from the company. Can't get answers from them about what was wrong, what needs to be fixed, and if it's covered under warranty. So going on 9 months no of no working solar due to SunPower being a disaster of a company. EDIT 4: Despite their own technicians telling me the system was not installed correctly, and was installed with poor practices leading to extreme fire hazard, and also telling me that the panels are dead but covered under warranty, the corporate office REFUSES to do the right thing and replace my panels under warranty, and fix everything that they did wrong. Their corporate office and customer service people are either evil or incompetent. It boggles my mind that their own technicians can tell me to my face that their bosses need to replace my broken system under warranty, and then their corporate office calls me and spins some crap about why they can't replace it and why they won't replace it. They couldn't even keep their story straight. This business is a dumpster fire of an operation, and customer service is like talking to ChatGPT, if ChatGPT got hit in the head really hard. Do yourself a favor and never use SunPower. I will be recommending against them to anyone who asks me about them. I will never use them for any of my properties, residential, commercial, or otherwise. The whole point of solar is to save money, but now I am in the hole tens of thousands because they sold me a hunk of crap. I am just glad my house didn't burn down with the poor and shoddy job they did on installing it.

Sunpower is it

Sunpower made what could have been a confusing and stressful process easy to understand and manage. Our project coordinator was very responsive and answered all of our questions (sometimes multiple times). The system was installed and turned on exactly when they projected. The technology and monitoring is a game changer in understanding and managing our energy consumption.

SunPower is a most surprising company to work with

After approaching 4 solar companies, I settled for SunPower, for the following reasons: Their proposal included a price I could afford; their installation timing and deadline were what I wanted; their staff was easy to contact, specially attentive to my scheduling needs; their panels were technologically very impressive, as proven by customers and publications' positive reviews. The surprise element was SunPower 's speed at installing the panels and their dexterity at scheduling the various/many inspections required for any solar project. Everything was masterly coordinated by my project coordinator, Katilynn, who communicated with me every step of the way, and earned my trust and respect, from the minute my contract was signed on 10/4/2023 through completion on 11/13/2023, when linked to my utility company. I recommend SunPower!
