I'm on someone's Excel spreadsheet at SRP, with the sheet called
"Assholes".
How did you get on that list?
AND
How did you discover you were on that list?
I use, at my last check, like 2 megawatts per year, or something
obscene like that.
Powering my server stack is a part of that, but it's probably not that
impactful. The two A/C, pool, pool heater/cool (like a third A/C unit)
... And my wife keeps the house around 68F all year ... Soooooo.
68 is cold!!
I home office so I have at least one PC on all the time. I have a Win10
laptop that I use often. SRP tells me I use less electricity than
average. Maybe what makes the difference is I do not have a pool.
I really do want solar, but my wife says that project isn't until the
late 20s, at best, probably early 2030s.
Who knows maybe the technology might be better then. Then again there
is the opportunity cost of delaying.
I really want the redundant A/B power supplies with the red cords and
black cords.
I'm the king of "Isn't that a bit excessive for a homelab?" ... So I
think this is right up my alley!

So solar usually pairs best with some level of power storage. and
amazon has some amazing options going right now for far less than
what you are getting quoted.
Just the fast search comes up with this kit for a ton less than you
are getting quoted.
Bear in mind you will have to add in the cost of connecting it to
your panel, but still an interesting baseline.

A friend was looking into solar with a Tesla wall (battery). I
looked at
her APS bill - it was $120/month. They were seriously considering
spending $25K to cut down on the peak demand charge. The most they
would
save was $20/month. That's an ROI that would never be achieved.
I have solar. APS invited me to buy a battery and they would pay
me
$1250 if I let them manage it. The battery was quoted at $15K.
Yeah, no.
So let's say I use the battery to keep my 4pm-7pm APS draw
minimized,
what is my ROI? Looking at my past bills, my peak demand charge
ranges
from $5 to $121 per month. Let's average that out to $65/month. So
$15K
to save $65/month gives me an ROI of 230 months. It will be less
due to
APS price increases, but that's still 15-20 years out, and by then
the
battery would need to be replaced, nullifying any notion of an
ROI.

Hi,
I have been curious about solar for sometime.
I am looking at my electric bill and I use less than 600k watts
a
month for 1/2 the year.
My math does not seem to work out.
1) Convert 600000 watts at 120 volts * .1 = 60,000 watts at 12
volts.
2) 60,000 watts divided by 30 = 2000 watts at 12 volts per day.
3) If I can harvest solar for 4 hours a day that is 2000/4 = 500
watts
at 12 volts.
That means I only need 500 watts of solar. This does not take
into
consideration loss of power in the system.
If the system losses 30% then I need around 715 watts of solar
panels
to meet my needs.
I was expecting a lot more.
Any help is much appreciated!!
Keith
