Had solar panels set up on my roof and they face towards the east (ENE, in the Southern Hemisphere). I know nothing about solar panels and little about physics, but I did a little experiment that has me worried. Before midday (10 to 11 am) I am getting around 1050K from the panels. After midday I get (1 to 2pm) around 800K and both with clear sky. This indicates to me that the orientation of my solar panels is poor. Can anyone please explain the science as to why orientation of solar panels matters?
