All absorbed light gets turned into heat, infrared or otherwise (I'm not sure why you brought up IR?); solar panels catch some of that spectrum. I'm not sure what argument you're trying to make here, particularly given the second paragraph seems to contradict the first; "extra heating effect" (from where does this "extra" come from?) vs "you could say they move heat if you like" which yeah, not really about what I like, that's just how physics works, can't get any more fundamental than the law of conservation of energy.

You said that AC/heat pumps "generate" heat and if they were powered by fossil fuels, in an roundabout way they do. But if they're driven by solar, there's no long-trapped energy being expelled and therefore no "extra" energy added to the system beyond what the sun is providing.
