Yesterday, heard a talking head on TV say that solar energy kits are
NOT cost savings. At the most, when you consider the tax breaks, they
generate zero net energy savings.
All I want is enough panel to run a 12,000 btu AC during the summer
when the sun is shining. What is it going to cost?

You need to do some studying.
Solar panels produce electricity. However, this electricity runs only small
electrical items. In order to get enough energy to power larger items, it
takes a system.
A system will consist of panels, batteries, switching devices, and
converters. You don't just plug an air conditioner into a bunch of solar
panels.
Systems are available for whole houses where people live in remote areas.
They power air conditioners, microwaves, tvs, clothes dryers, and all. But
it is a system, and not just panels you plug into your air conditioner.

about 20- 30 thousand dollars for a system. Every system says things like
"NO" eklectric stove, base heaters or A/C units...
Try calculating it here

There was an article in EE Times a few weeks ago from the guy who runs
Cypress. He says PV panels should wholesale in the $4 a watt range
based on his cost. That may end up being double by the time it gets to
the consumer. Your A/C probably pulls 1200-1800 watts, depending on
SEER. Depending on how close you can get to a wholesaler and what
machine you have it looks like you are talking about $5000 to $10,000
anyway and it could be more like $15,000 if you pay somerone to do it.
At my FPL electric rate (12 cents a kwh) it would take 50 years to get
$15,000 back. (based on $8 a watt)

A real problem with solar panel is the plastic and rubber parts fail
because of continuous sun exposure. The MTBF is shorter than the payoff
period. Nobody has reinstalled them after they fail around Boston.
