Hi Pete,

I am in Palos Verdes, CA, just south of LA (I think that is what you are
asking here).

I could get PVWatts to exactly match the watts I generate with some tweaking
of the parameters. I think it is a pretty good tool from what I can tell
with my system.

best,
doug

what did it cost to get this all purchased and installed
I am very curious!?!

It would depend a great deal on where you live and what rebates/tax breaks
you can get. I signed the contract back in 2006 while the rebates were
better in CA than they are now. In general, though, a system like this
installed, grid-tied, with permits and taxes would retail between $8K-$5K.
Depending on where you live, you probably should expect $0K-$0K discounted
for rebates and tax breaks.

So, you probably would pay between $8K-$5 OOP when it is all done and
said. It might range even higher or lower depending on your installation
(e.g., tile roofs are harder to do than composite). Maybe installation would
be less expensive in other areas than in SoCal (we tend to pay a premium
here for many services, gasoline, housing, electricity, property taxes,
etc.).

Although there are variables, it pretty much formula-based -- somewhere
between $-$ per watt installed, so it makes sense to try to get your load
as low as possible before sizing the array (change out the pool pump, switch
to CF lighting, energy efficient appliances, efficient AC unit, etc.).

best,

doug

 I am in Tybee Island GA - coastal town in Georgia
We get a lot of sun here - almost all winter (it rained maybe 3 times -
evening and night)

I would build a roof over our deck South facing to hold the panels
My electric bill states usage of 3100KW/mth average in the winter.
That is quite a bit methinks!

The pool pump is a new variable speed pump but I have to get the pool guy to
do some tweaking as it is on 24/7 (150W~3200W/hr)
I am also going to go solar hot water heating as that is a major saving

Any comments?

I figure that my annual usage is about 48000KW before Solar water is
installed.

I still think something is strange about our usage as we are pretty careful
about energy - A/c has not been on for 4 months

We have an analog meter that always seems to be spinning very fast.

How often do these meters fail?

Oh yes.

Pick one; your supplier is robbing you blind, you are an energy pig,
you have made an error in your calculations. What excuse could any
household have for using more than 130 kWh a day.

See above.

Time for you to investigate what is going on. Turn off all breakers.
If the meter does not stop running you have a problem.

If the meter stops, turn on one breaker at a time and turn off all the
loads on that breaker, the idea is to identify every load you have.
Keep a list. Get a watt meter and use it on every load and record it
on an energy audit.

When you have done this you will have a better idea of your energy
use. At the moment you're just guessing.
