I'm expanding the 10kW system I have, I want to orient the panels vertically in front of a barn wall that I'll paint white, so bifacial panels seem like a good choice. They will use a different inverter than my existing system so no compatibility needed. Physical dimensions need to be no greater than about 45" x 90", and I'd like them to be at least 400W. The panels I have are ground mounted QCell Duo, but I bought them 3 years ago and haven't paid attention to the market so don't really know what's available. I'm buying new, not used, and don't need to be on the bleeding edge of technology, just want a solid performer. Any recommendations welcome. tnx
