The three solar panels on this van point in three different directions: left, front, right. The fourth direction could not be harvested - in the back there is only the metal roller shutter, no option to affix a panel there.
And the total capacity of the solar controller is max 80 V. With the three panels I usually get during idle a total voltage of 65V. This means I cannot even connect a fourth panel in series there.
Today I parked the van in such a way that the sun only came directly from the back. Means no direct sunlight on any of the panels.
And surprisingly, there is a power still generated, as the display shows:
12.5W and 0.35A are being sent to the controller, and from there into the battery. This is quite amazing and surprising.
