Solar Panel Shadows and Bypass Diodes
The following data was collected from my 3x250W flat mounted solar panels on 1/16/15 in my storage area in the Phoenix area. The graph shows the significant transition as the sun just covers the 3rd r...

Hi brulaz,
If the panels have bi pass diodes and are poly or amorphous then some power is going to go to the controller.
For example, at solar noon in June in rain, I sometimes get 3 amps of output from the controller. Under perfect conditions with loads on the battery bank I get 17 amps. The panels are in series parallel for a vmp of 33 volts. This allows the controller to output some current 30 minutes after sunrise.
