Hi all - I am looking to get a 10KW system (25 x 400W) installed on my roof and the panels offered by the installer is VSUN400. The original plan was for Silfab but looks like it's backordered and now VSUN400 is the only option. Please let me know your thoughts on this brand

Also, looking at the specs, these VSUN panels are supposedly bifacial - "Up to 30% extra power generation yield from the back side". I am not sure if this would have any benefit when roof mounted or needs any special mounting configuration to get any benefit. More importantly, I am wondering if there are any drawbacks to this kind of panels v/s the regular panels. Appreciate if anyone can shed some insights on this.

Thank you!
