Even without solar collectors, ground-source heat pumps store and reuse energy. When cooling the house for the summer, heat is rejected to the ground. When winter comes, that heat can be extracted from the ground to heat the house. As spring approaches, the ground has been cooled after the witner and is thus is a more efficient medium for cooling the house.

Yes, however many places in the U.S. do not require much AC in the summer but require a lot of heating in the winter. Storing a lot of heat in the summer from solar thermal collectors can provide a lot of heat in the winter, saving lots of energy and money.
