It should be simple, but.....
I have some Renesolar Bifacial Double Sided panels specced as 425W front 90W rear - so when I'm looking at sizing my array so as not to overload my inverters max input, what figure do I use? 425 + 90 = 515W? But as they are on a dark green roof, not a white one, and half are mounted at 20 degrees and the other 40, will it be less. But how much?
My 5kW inverter can take 6500W in, so assuming 12 panels at 5100 front and 1080 rear (max) = 6180 will be fine - but could I put 14 panels on there?
front = 5950 W front and 1260W rear = 7210W notionally, but as suboptimal angle for front half will lose ~10% (making ~5600 front) and much less efficient at rear (say 50% less efficient overall - low panels at front and low albedo ~600W rear) totalling 6200W so within inverter range.
Any suggestions as to what will work?
