Anyone have experience with these "solar assisted" air conditioner/mini split?

[J.P.M.]

But we will almost ALWAYS need max cooling, except for weekends when we let it get 82*... and even then it probably runs balls out to stay there! LOL

Before I did anything else, I'd get/do an energy audit (if you haven't done so already). With that information you'll then have a better idea of whether or not net metering will be more/less cost effective than no net metering.
