1850 sq ft. Heating and hot water is NG. We averaged about 1100
kWh/month for the two years before installing solar - about 500 kWh min
and 1800 kWh max. We are somewhat more careful in turning of lights etc
since. The 6kW system so far has produced:
Dec: 736kWh
Jan: 818kWh
Feb: 945kWh
Mar: 1100kWh (projected since it's currently 986+ approx 40kWh for 4
more days)
The June number should be the max and I'm guessing 1200 - 1400 kWh
Ok...that makes more sense to me now... 1100 kw is a pretty impressive
output for solar.
NG for heating and hot water really saves the $$$
Water heater, dryer and heat pumps are the big ticket items for lots of
KW's.
People are anal about the lights, but you could leave ALL the lights on
24X7 and still not burn many kw's.
Say 1000 watts a day for 30 days = 30,000 watts per month / 1000 = 30kw
x .08 = $2.40 per month for the lights. (10 100w bulbs burning 24x7)
????
You don't pay for electricity by the watt-day, you pay by the watt-hour.
Multiply your number by 24.
PS: Electrical Engineers may now jump in for corrections.
10 bulbs X 100w = 1000w (or 1kw)
1000w X 24hr = 24000w (24kw)
24kw X 30 days = 720000w (or 720kw)
a Kilowatt hour is 1000 watts.
So 720000w / 1000 = 720kwh
If you are stuck on a Co-Op electric system you are paying about twice
that of the average person ($0.18) - otherwise about $0.09 a kwh)
720kwh @ $0.18 = $129.60
720kwh @ $0.09 = $64.80

For since the creation of the world His invisible attributes,
His eternal power and divine nature, have been clearly seen,
being understood through what has been made,
so that they are without excuse. For even though they knew God,
they did not honor Him as God, or give thanks; but they became
futile in their speculations, and their foolish heart was darkened.
