410W Longi B Grade – Black on Black

Brand New B grade panels so they will have some sort of cosmetic defect that does not affect the safety or performance of the panel. Example is caulk on the glass that can be scraped off or a solar cell that has a chip in it or bus bars that are wiggly behind the glass. You will likely also find something I haven’t described here! We have uploaded a few examples of what we’ve seen that make them B-Grade panels. The panels we’ve looked through also do not have a standard spec sticker on the back, it’s a more generic sticker that is missing the UL listing logo/number. We have done spot testing on these panels and haven’t noticed any issues. These do not carry a manufacture warranty but do carry a 1 year from Beene Brothers to make sure you have time to see them working and verify no DOA’s.
