Hey all, I was wondering if the ability to go retro-transpose POA information exists in pvlib. For example, if I have POA, surface azimuth and surface tilt could I back out GHI and DHI? If this doesn't exist yet, is it something that would make a good addition to the library? |

It is available in
pvlib.irradiance.gti_dirint. There's no unique inverse function POA -> GHI; one has to assume a model for sky diffuse irradiance component, hence the namegti_dirintwhich uses the DIRINT model for sky diffuse.
