Your documentation should give a yearly kWh average, for basic
calculations. A clamp on ammeter would give current draw for a given
point in time. An hour meter would give you run times per day, but you'd
have to calculate fan and compressor current draw and elapsed times
separately.

compressor current draw (amps) * volts = watts
watts * daily hours = compressor watt-hours

fan current draw (amps) * volts = watts
watts * daily hours = fan watt-hours

compressor watt-hours + fan watt-hours = total watt hours daily

It's usually not cost effective.

I'm guessing from paul posting , that the best i can do is reduce my
electric bill.

From the web page Paul. Only one town near me gives net meter of 25
kw. So what size solar would i need ? I will have to check my town
requirements.

I would say that it is always best to check out any regulations,
requirements
and rebates before deciding. In California they will pay \$-3 a watt for
your
PV system and Netmeter at the rate you pay for electricity. If you are
producing
electric at high noon on a summer week day you could get even more with
time of day Netmetering. Check you local listings...your milage may vary :)

You can save energy by setting a warmer temperature.

There are split or ductless room air conditioners that are nearly
as efficient as central air, but allow you to air condition room by
room. Conditioning only rooms you use, may save on electricity, and
the cost is much less than PV. Conventional window units are much
less efficient, but cost less too.

If you live in a humid climate, you may be able to save on
electricity by installing an adsorption dehumidifier; though, I
don't know if any are made for home use. Lower humidity allows you
to be comfortable at a warmer temperature.
