Chris, Sunpower has taken some responsibility on some of our older Sunpower systems that are arc faulting. We tell them that a system is arc faulting, and then they insist on sending up a 3rd party contractor to inspect the system and potentially install what they call "Tigo Diodes". I am still not exactly sure what that is. It also seems to take them months to send anyone to upstate NY, as we have a bunch of customers that have been waiting months for the 3rd party contractor to come take a look. You likely could only follow this route though if the system was installed by a Sunpower dealer and you are a Sunpower dealer yourself. If the original system was from a Sunpower dealer, you can also have the customer call Sunpower directly.
