Solar panels mix well with heat pumps in hot and dry climates indeed, because of the happy coincidence that peak solar radiation=peak demand for cooling. In that case it's not a bad combo, especially if you have mild winters without temps deep in the freezing (which ruins the COP for heat pumps, assuming you use them for heating too).
