Hi, Will. Apparently, Signature Solar no longer sells the Q.ANTUM DUO's Q.PEAK DUO L-G8.3/BGT Bifacial 410W Solar Panel listed on your website; your website link no longer works. At your earliest convenience, can you please update the link to either another reputable source for this particular bifacial solar panel you tested, own, and recommend; or, to a comparable bifacial solar panel that you recommend? I am eager to purchase four of these. Thank you!
