I agree that the time to process warranty the module to a manufacturer's desires is cost-prohibitive. Of all the component's we use, this warranty almost seems the least valuable for this very reason. We stopped one case for this very reason as I didn't want to do a PhD dissertation for a single module.
Was surprised by one manufacturer who advised us to read that bypass diodes were not an warranty defect even though the module was making half power. Good luck, look forward to hearing how your case goes.

Right now, in order to Provide what they are asking for, we will likely spend more time/money testing to their satisfaction than it would cost for us to likely buy new modules and just replace the array. Anybody have a similar experience? Or suggestions on how to deal with Sunpower? Don't want to bog this down with all the details but suffice to say we I-V traced the array at the string level as a sanity check (7-10 % lower than anticipated performance), and a random selection of individual modules as well and we are seeing roughly 8% lower performance than expected given the array age and listed performance warranty. (STC corrected I-V trace is 8% lower than it should be for an 8 year old solar module from SunPower) With Regards, -- Danny Young NABCEP PV Installation Professional #031508-90 Engineering Team Lead Solar Energy Solutions Lexington | Louisville | Bloomington | Cincinnati | Evansville | Indianapolis 513-448-5176 (mobile) 877-312-7456 (Main Office) <mailto:da...@sesre.com> da...@sesre.com
