<div dir="ltr"><div><br></div><div>Mac - My understanding is modeling production from the back of bifacial modules is pretty tough, but as you've probably seen data sheets often have a few levels of back-side production boost factors. I would consider contacting manufacturer(s) to discuss modeling production for your particular situation.</div><div><br></div><div>Re: mounting, I think each frameless bifacial manufacturer has their own compression-based clamp system, but Silfab does make a framed bifacial module. Advantages of frameless are aesthetics and no need for module grounding. A disadvantage is that you can't use traditional snow-retention methods but that doesn't sound like an issue for your project. Frameless probably sheds show faster.</div><div><br></div><div>Here's some info I've been gathering for a carport project we're looking at:</div><div><br></div><img src="cid:ii_15cd0fea64eef61c" alt="Inline image 1" width="816" height="176" style="margin-right: 0px;"><div><br></div><div><br></div><div>Lumos is another [expensive] option.
