According to most solar panel manufacturers no only pure water should be used that’s what is stated when you sign a contract to clean them , but in the real world it’s glass like a window so don’t  see that it would hurt anything

I personally wouldn’t use UBIK on solar panels, especially in this hot weather. From experience it’s not suitable to be left to dry, you can have terrible problems removing the residue if it does dry.

Just pure water and a good scrub.
