Our next-door neighbors do, and it doesn't.

I have some flexible solar panels I can use on a boat or in the garden.
As long as the electrickety company works I do not use those.
If the mains breaks down I put those out, experiment has shown it is enough for cooking
and maybe run the fridge, have 250 Ah lipo battery pack and a pure sine wave converter too.
Also a small fixed solar panel (about 80 W) in a window in a bedroom upstairs, >it mainly blocks outside street light but has been used to charge batteries.
No need for any financing...
The mains companies here now start asking for more money for electrickety if you feed back into the grid,
as it causes them to build more capacity....
OTOH I have survived in the wild... even the US wild... without solar power.
Bad sales people here at the door too, I just close the door on them.

Is your utility power unreliable? Ours goes out roughly twice a year,
but just for minutes during the day. The way we know is that the
clocks on the kitchen appliances are wrong.
We have a friend that is "finding himself" by hiking the entire
Pacific Crest Trail. He has portable solar cells to charge his phone
and flashlights. When a guy does that, it may be bad news for his
wife.
Safeway is jammed with people buying all the available bad beer and
junk food. There may be some important sporting event today,
synchronized swimming or pickleball maybe.

Yes, I do. Have 3.6kW of panels since 2003 - I was a very early adopter
and did not do it for financial reasons but as a fun thing to do. In the >early days it was very satisfying to watch the spinning disk meter run >backwards on bright days. I reckon finances broke even about one-two

Forgive my ignorance, but what does that mean?
Let's say you have 5 hours of sunshine, do you get 18kWh of energy?
Does that mean the max voltage current is 3.6kW (36V, 100Amps)?
And how big an area is that?
A typical panel is "about" 300W (some more, some less) and operates
at about 48V.

Thanks. Every time the power goes out. I think about solar powering the well. I keep buckets of water in the shower to flush the toilet when there is a power outage.
There is a storm big enough to create a risk of a power outage
every other month.
I lose power maybe 3 times a year and like every 3 years
it last for days.
The well pump is 240VAC 3amps but it only runs for maybe
a minute a couple of times a day. So I would need a 1000W inverter, a battery that can supply a lot of current for a short duration and then be trickle charged most of the time.
Sounds like a car battery to me, but maybe there
are better batteries for the job.
Sounds like a single panel would keep the
battery charged between pump runs. But then I always think it is more expense and trouble than it is worth to avoid keeping buckets of water in the shower.

Can you store the "pumped water" instead of being at the mercy of
the (inoperative) pump?

The deciding issue would be whether or not you can store
"enough" to cover all potential outages. What if 5 days?
Or, if you find a need for water for some other purpose?

I've thought about that to, but it would have to be in the house to
avoid freezing and there really isn't any room for it.

I have water in the well-head and in the water heater but I reserve
that for drinking and keeping the pressure up in the system. I can
refill buckets from the creek or the pond and in the summer I have a
rain barrel and in the winter there is snow. I've only have had to use
the creek and the rain barrel to refill the buckets. First thing I do
when the power goes out is shut the valve on the toilet. I can flush
that with non-potable water.

In detail I have 20 panels each rated 180W output at standard solation.
They are Sanyo hybrids each with approx 1.6m square area. Over the past
20+ years the price has fallen and output (i.e. efficiency) has
increased. Hybrid here means mono-crystalline silicon cells with
amorphous silicon cell layers.
Those 20 panels are wired as four strings of five in series. The open
circuit voltage of one panel is 60-70V. Each pair of strings is
paralleled and feeds one of two 1800W grid-tied inverters. The DC input voltage to the inverters is 300-350V
Yes, if there were 5 hours of "standard" sunshine then 18kWh energy
would be generated.

18kWh 0.2$/kWh 365days/year 20years = $26,280
Based on below average solar insolation, cost of electricity and system

of places. Why pay more?

What do you factor in for roof maintenance (do you get 20 years out of a roof?) and the licensed installers who have to disconnect your kit
before you can make those repairs and then reinstall -- and have it
inspected -- before you can resume its use (costs that would be
unnecessary with a "clean" roof)?
Note that even if you reduce your demand to fit entirely within your cogeneration capabilities, you will have to pay the utility if grid
connected -- even if just a fixed, monthly "service charge". And, what
they charge can be varied, over time ("We need the solar folks to
subsidize the RENTERS who can't have their own solar power..." etc.)
The utility, here, is working HARD to make solar as expensive as
possible using every legal lever they can manipulate (and, they have far
more clout than individual users/cogenerators)
[I believe I am located in the BEST place (desert southwest) for solar
-- in terms of conceptual payback -- yet it's a struggle to beat the
hurdles that are placed before your adoption!]

Good point, the roof needs to be considered in your economic analysis, and unless you have a roof which can be expected to last more than 20 years - brand new fiberglass shingle, or metal, membrane, tile in good condition - then it will be most economical to replace the roof at the same time solar
is installed.
Unfortunately the low first cost fiberglass roofing is more
popular than the durable low life cycle cost alternatives with a good
chance of outliving a 30 year solar installation.

A common problem in the US, utilities which do not want competition are making the "contributions" which insure that legislation written by their lobbyists is enacted.
In Florida a regulation requiring all solar systems
meeting more than a small amount of customer demand be utility owned and operated - they rent your roof and give you a bit of a raw deal discount
on electricity - was soundly defeated in a voter referendum despite heavy deceptive utility advertising, and then enacted by executive order by Ron DeSantis, recipient of big utility "contributions". Not much Solar in Florida.
Texas by contrast has little regulation and loads of solar.
Here in PA we have decent regulations but only moderate insolation,
payback time is longer but still worthwhile for those with a good
location.
