Perhaps, since it is an add-on to Advanced Solar Panels, the functionality that should be fixed by this mod does not cover this one, and as a result, it just appears to be incompatible with this mod.
However, if you want to use a mod like Super Solar Panel in 1.12.2, you will need IndustrialUpgrade or XXL Solar Panels, versions of which are no longer available for download.
