I am working on my first off grid home, and
that
again. So natural gas vs electric heat pump for heating would
probably be the same energy cost.

I’ve wondered how long firewood wood really last if everyone was trying to use
it. Wasn’t there a firewood crisis in the 19th century before they started
using coal for everything?
I think reliance on firewood in the apocalypse comes with an implicit
insulation? Does that mean R57 in the walls instead of R19?

Maybe it’s a matter of being self-reliant until your solar panels break vs
being self-reliant until your fuel runs out
: Re: [AFMUG] OT: Major off topic. Off grid home
That said, the last time I checked, propane and wood pellets cost half that of
electricity for heating. And natural gas was half that again. So natural gas
vs electric heat pump for heating would probably be the same energy cost

3.41 BTU per watt for resistive heating. Heat pump gives you way more heat per
watt. That is why most of the electric cars have gone to heat pumps for the
heater
on the differential temperature and the design of the unit. Unless
the outdoor temp is down at the vaporization temperature of the refrigerant,
you will always multiply your heating energy.

Mini splits are not manufacturing heat out of the electrical input ( ie
resistance heating ) they are moving thermal mass from one side to the
other. So they are making the air outside even colder and the air
inside warmer, why the efficiency goes down as it gets colder. You have
to wrap

A mini-split is FAR more efficient in a particular range. The ones I've
gotten in the last 4 years are incredibly efficient at ~40-80 degrees.
They're still decent at -8 through 40. Not too good when colder than -8,

Say a similar on grid home used 500 kWh per month. That is equivalent to a
steady state load of almost 700 watts. Round up to 1kW. So 10 kW panel
minimum. Panels are cheap these days. I would do 20kW if you can. Batts are
not so cheap. That is where you can save some big money with a
10x average load for panels. 3 days of battery plus backup generator. Have
generator control based on battery voltage. Overcast days yield 5% of full sun.

Are your batteries 30KWh at what voltage? The higher voltage, the better.
A higher-end Tesla model S is about 3X that size (90 KWh).
