If you somehow think that an off-grid solar system is going to save you money on air-conditioning, you are very much wrong. Off-grid solar is the single most expensive form of electricity. The only time this type of solar is cost-effective is when there is no grid to tie into. The combination of the battery bank sized to adequately run your loads, coupled with all the electronics to run it, gets quite expensive.
A much more cost-effective solution for your situation is a grid-tie, where you are getting a credit for the amount of electricity you produce. The contracts though vary widely from one jurisdiction to the next. The best kind of contract features net metering, but most contracts today are far less lucrative. For example, the power company buys every watt of electricity from you at 5Ç a kWh, and sells it back to you at 15 Ç a kWh.
Do I use solar; absolutely. Do I have air-conditioning; absolutely. But I have a cabin what is 15 miles from the nearest power pole, so that what makes solar air-conditioning cost effective.
