After billing for first 3 months of 2012, here are the results:

kWh(solar) Elec$ (total/elect) Bank (on/off)
January: 819 $32.04/$5.63 105/0
February: 945 $24.07/$3.11 278/0
March: 987 thru 3/27 $18.79/$0.08 525/0


What size space are you heating/cooling ???

That's a very small KW usage for the average house.


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)

PS: Electrical Engineers may now jump in for corrections.

if you own the system, you don't get a check. you get a credit for
future bills in the next year. i don't know what happens if you're
leasing the system.

last year i generated 14200 kwh, which resulted in a $200 credit at the
end of the year. my total charges for 2011 was $430 (including fees),
about $1650 under what i estimate i would have paid without solar. i
have a 2800 sqft house with 2 ac units, and run a couple of electric
kilns a lot, so my typical usage is higher than yours.

so far this year i've generated 2890kwh, more than i've used so i've
been generating more credits. since my bills haven't totaled 200 yet, my
1st 3 bills this year so far are $0.

you can upload your data and plot your generation at http://pvoutput.org
to compare your generation with others. my system is

Charlie,

Are you a Solar City customer or did you purchase from some other solar
company?

How do you upload to pvout.org (automatically?) your stats?

I'm leasing my system as I couldn't afford the purchase and as well the
lease includes any maintenance and a purchase didn't.

On the lease, any annual credits are paid to me rather than carrying over.

Thanks,

- Doug

i bought my system.

if you have a login to pvoutput, you can add either 1 day at a time, or
if you have a .csv, you can bulk upload 3 months at a time.

once you're logged in, you can use this
http://pvoutput.org/addoutput.jsp to upload a day. at the bottom are
links for different multiple uploaders.

????

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

1000w X 24hr = 24000w (24kw)


watts x hours is watt-hours, not watts
24 kwh

24kw X 30 days = 720000w (or 720kw)


72000 wh (72 kwh)

(Actually, 24 kw for 30 days would be about 17 Mwh, and probably melt your wiring).

a Kilowatt hour is 1000 watts.


1000 watt hours

So 720000w / 1000 = 720kwh


(I assume you get it by now)

If your units don't make sense, don't expect anyone to believe your numbers.


I'm not an EE, and I assume neither are you.

I think my math made enough sense.
I don't want to quibble over terms but I think if you understand what I
said you wouldn't say that 24kw for 30 days would melt the wires. The
24kw was the days cumulative watts (which my math made clear).

All energy was expressed in watts until a final conversion to kwh...
Kilowatt Hour: noun - :A unit of energy equal to the work done by a
power of 1000 watts operating for one hour
Kilowatt: noun - A unit of power equal to 1000 watts

.... but for someone simply wanting to calc their bill and not planning a
wiring system (as the discussion) dividing watts by 1000 is kwh.
