Let's go ground mount, non tracking seasonal adjust rack, no shading, 46 degree's N latitude, 1905 hours of bright sun yearly which is about 5.2 hours/day.

How do I work out the loss from the rack?

I just found this site

I'm assuming when you say micro inverters mean we can ignore the efficiency loss that means I can set the DC to AC derate factor to 1.00 or .99?
