    I am advertising that I had enough of Sunpowers failed promises to fix my system.

    My favorite Sunpower excuse... my positive ground system was grounded on the negative. We have to reverse it. It takes 30 days for the electrons to realign.

    Yet again 30 days later. The same story in reverse.

    Electrons take 30 days to align. As if I am that stupid.

      Sunpower tried to tell me their certified installer had to honor the warranty. Not Sunpower.

      7 years of little production. Then they tried to say my ten year inverter warranty expired. After I have been complaining for 7 years?

      No reimbursement for the production loss. No compensation for my SREC losses (that were calculated in my pay off equation)

      I do not want others to fall prey to Sunpowers failed promises of honoring a warranty.

        I have a good relationship with a Sunpower installer who put a small system on a townhome that I rent out. It is too soon to tell if I will have any problems but maybe I am the exception not the rule. On my current home I did buy some used Sunpower panels and they are working fine for being 10 years old. I don't have any expectation of service or warranty but I was drawn to them because of their reputation. Good luck with your situation.

          I don't know a manufacturer that offers reimbursement for production loss. My installer of a SolarEdge system offered a production guarantee but the agreement is silent about reimbursement for production loss. In any case I know it does not fall on SolarEdge. Does your contract have terms to that effect? Did Sunpower warranty production?
          I don't mean to sound like a Sunpower fanboy but it sounds like you got a bad installer. Could the production loss have been the result of a bad system design?

            Sir,

            if you like I can send you a copy of the production guarantee. I would not disparage a company without proper documentation.

            The installer was not the issue. The installer was the only one who used a dome looking sun meter and told me I had to cut down a tree due to shading prior to install.

            The installer worked hard to get the issue resolved but Sunpower engineers refused to listen. Black burn marks on the rear of the panels seemed to beca dead giveaway to the men that tried to do the repairs.

            oh and the monitoring device that was supposed to alert problems ( that i paid extra for ) nope that never triggered a response or alert from Sunpower.

            Did you read my post about electrons aligning? Really?

            I may not be an electrical engineer but I did pass a few science classes in my day.

            I stand by my statement that the system failed. Sunpower ignored me for years. I finally filed a consumer fraud case in Federal Court and am awaiting the class action certification.

            If my claim was without merit I have faith that a Federal Court Judge would dismiss it with prejudice.

            Sunpower did try to blame the installer. Even though the installer was their “certified” installer.

            If you need anymore specifics to validate my accusation I am happy to supply then.

            There does not appear to be a shortage of BBB complaints for failure to repair or replace Sunpower failed systems. On the BBB page they even promise to pay for lost production to another complainant. Never offered me a penny for the loss I took.

            Buyer beware. Sunpower is a huge disappointment.

            I am hoping others who have been bullied by Sunpower speak up.
