For those of you in the zones with less direct light, you will benefit more from the poly crystals. The monos only produce in direct over head sun light.
Plan B is to use more so you make the most of the few hours you get. I tried wiring some panels in a series/parallel arrangement with a switch to take better advantage of low light. Problem is the mppt technology is a bit slow at loading up a panel for the optimum amps/volts.
Second, although the sun may seem to be slowly decreasing in brightness as the afternoon rolls on the light the panels are using for power varies. Ive seen wild variations in output for something I could not detect with the naked eye.
Same when its over cast or a brief cloud. I see wild swings in output, but nothing by the naked eye.
