I made an PV surface simulation with the Ladybug tools including the Ladybug_sunpath Shading component.
In the first simulation I used simple surfaces which cover most of the roof.
In the second simulation I splitted these surfaces into smaller parts so I could get a better view of how much energy on which spot is generated. Unfortunately the results of both simulations differ quite a lot. I used for both simulations the same parameters. (the energy per year is written in white)
What could be the issue here?
(I used the standard template: 020_Photovoltaics shaded analysis)
