Do they even have those and if so, where can I buy one for a large two story house in southern California? Thanks

hmmm....
you'd spend way to much in panels to get any type of ROI.
your home, depending on where you live, is going to require 3.5-5 tons of cooling.
depending on the efficiency, your looking at approx. 30-50 amps @230v.
the sol cool unit, i'm skeptical of. it uses 134a, which is odd, but should work, IF it's a new install.
if your trying to replace the condensing unit.
IT WILL NOT WORK RIGHT!
the metering systems (r-134a vs r-22 ) are different.
the coil circuiting *may* be different.
the oils are incompatible (mineral for r-22 vs synthetic for r-134a)
r-22 is the refrigerant most likely to be in your household a/c system. (there were systems that used r-500 and r-12 but that would be pre-70's, and even then it was uncommon)
the warranty is much less than a conventional a/c (3 vs. 5-10 year)
another thing is it says it's 22 seer. unless it's water cooled, i don't see how they can get the efficiency up that high, in such a small package.
the cost of operating, theirs vs. conventional, is HIGHLY, HIGHLY skewed. i pay half of what they claim a 2 ton costs to operate.
i have a 5 ton and that's not including the rest of my power consumption (like an electric water heater).
there's just not enough info on the website to give an informed opinion.
the evap cooler may or may not work for you. it depends on temperatue/humidity levels in your specific area.
higher humidity leaves less cooling capacity as well as high temps.
if it's over 100*F or 20% RH, your not going to be happy.
if you want to conserve look at
www.freus.com
they have a/c systems that are in the 22 seer range. they require more maintenance than a standard a/c, but work well.
they typically cost twice the amount of stardard a/c units, but up to 50% savings on electric consumption over them too.

I have worked this out before, just to run a window unit, you would need at least a 2000 watt system, with a good sized battery bank. It would probably cost $10,000.00.

Too expensive to be practical. Here are some more cost effective ideas ...

You would have to have a solar assy. and battery bank and inverters....to get just a solar a/c unit is impossible.

There is a MUCH MUCH MUCH better way to cool a home.

idk but they'll come up with it...search google.com or try to contact solar panel companies
