That's a very large residential A/C. Our 4-Ton unit (48kBTU/Hr) takes about 5kW and suffices a 2,900 sq ft house in northern California. (Don't you like all these antiquated units!)

California encourages (and will soon require) heat pumps for domestic hot water, that gives you a threefold improvement in efficiency if running from solar generated electricity.  They are pretty common.

Here in PG&E land around the SF bay we're allowed up to 10kW of solar generation without significant additional requirements.
