I tried to run some tests to calculate the solar radiation on a horizontal plane with different components (PIT, RAD and DC). I used San Francisco climate file. I found some weird results:
- As you can see in the figure attached for all the methods the radiation value is not uniform all over the plane.
- Using RAD component the value doesn’t “match” the global horizontal radiation value from the EPW.
- Different results between RAD e DC simulations. DC results are closer to the climate file.
Can someone help to figure out why these strange results occur?
Attached the GH file.
