Pianotuna: it’s interesting to note that I’ve read that plain monocrystalline cells perform better under test conditions but recommendations for the best low light panels include both poly and mono types. So a lot to be said for the manufacturing.

alot has to do with the actuyal design of the panel also. split cell mono panels give better low light preformace than non split cells, 24v panels have better low light preformance than 12V. also how many bypass diods are they using and so on. a mono panel should out preform a poly if they are built to the same specs, its when you start comparing cheep mono to quality poly panels that things get skewed.

basickly poly panels are made from the reject wafers that were suposed to be mono panels, that why they need a larger size for the same output, are less efficent and so on. but weather its a poly or a mono if its sized properly they will both have the same result.

Except I think I’ll use thicker wire to the controller.
#8 is also readily available.
