It's a gimmick. Look up "solar assisted heat pump" and you will find many variations of the idea. There is no such thing as a free lunch. To move heat, the rig must absorb heat. When the panels absorb heat, they either overheat due to no load or become a frosty ice maker element due to more load than sunlight. In the cooling mode, the sun works against the panel. Many of these rigs have been known to explode on a hot sunny day in summer.

The rigs that actually do work well and run off solar are powered by pv panels. More panels equal more run time. Here's an example system that Ford guy is considering:
