Optimum bifacial height?

[Lt.Dan]

I plan on mounting 6x 390w bifacial panels on top of a white roof, is there an optimum height off the roof? 2"? 6"? Or is the juice not worth the squeeze?

Most references I've seen recommend the panels be mounted 1m above the surface.

Got it. These will be mounted to a mobile Enclosed trailer. Definitely don't want to be that high lol. Sounds like it's not worth the squeeze

Higher the better as panel shadow is blocking smaller part of visible background ”reflective” area (soil, snow, roof) Practicality is another matter.
