I was calculating some PV surface outputs that noticed there is a difference in the Radiation result of “Radiation_Analysis” and PhotovoltaicSurface". So I do a simple test with a cube. As you can see the PV component considers radiation for the bottom of the cube which should be 0(as it is the result of radiation analysis) Also the Number of irradiances in the North direction is nearly doubled.
I would be appriciated if you have faced same Issue or have an Idea how to fix it?
I suggest that you use the LBT 1.6 plugin instead of Legacy Ladybug. The Legacy Ladybug radiation analysis did not include an emissive ground hemisphere, which helps approximate the solar radiation that would be reflected off the ground onto the geometry.
I’m using PhotovoltaicSurface regularly. Doing a comparison with pv-sol, notice me this differences. How can I improve accuracy of PhotovoltaicSurface as there is still not new version of it in LBT, or in another word how to use this new result pf LBT 1.6 into old PhotovoltaicSurface component?
