We just took off the factory hose and had the propane company come out and
hook it up to a 250 gallon tank outside. We've also got an electric
propane valve on it, controlled by the generator controller so we can turn
the LP off when it's not running.

I had 5120 TEGS powering 7 mountaintop sites for about 8 years before I sold
the system. As long as there is propane, they work. No moving parts, very
little maintenance. It doesn't matter how cold or hot it is, they just work
. Simple power that provides heat for the radio shack as well.
Yes, it DOES matter how cold it is.
Propane won't create gas pressure below -43.6F and many propane gas pressure
regulators will ice up and stop working below about +20F.
This isn't a problem for many locations but it is still important to know
what the limits are.

The secondary regulators are housed in with the TEGs and the primary

Can't violate the laws of physics.
http://en.wikipedia.org/wiki/Propane
Boiling point (point where it will turn into gas) is -43.6F
If the propane is colder than that, there is no gas pressure.

I think that depends on how far away the mountain is from base, how long
you stay on top of the mountain and whether or not the helicopter is still
running while you are working due to the cold and altitude. An hour in a
helicopter in Alaska runs about $1800 last I checked and they bill in 15
In my case, the propane was in various sized tanks from 100 gal Pig tanks to
1000 gal tanks depending on access. The most remote ones we used 100 gal pigs
(14 per site ) and used helicopters to fly the propane. Made for more trips but
the cost of the helicopter to fly big tanks was horrendous.
Even north of fairbanks Propane does not have much of an issue. Insulate
and enclose for success.
I use a 1500 gal tank so I can get the 1000+ gal discount. They even
apply this discount to my home propane purchases for the rest of the year!

$10k is a round-number summary deployment cost.
Most of the mountain top sites we had were at least an hour one-way from
Anchorage. And of course we had to pay for the bird to sit there while the
technicians worked on the site.

If the regulators are inside then there won't be a problem with regulator

Gas regulators have to have access to ambient pressure to work properly, so
they can't be completely inside of the tank.

We use a lot more then 100w though typical tower has two licensed
links, 6 sectors, a few other unlicensed backhauls and two 24 port hp
switches with 2 SPFs each, a router, thermal fans on two separate boxes, 3
DLI remote rebooters etc
How do you get away with 100w of power at a tower
If I remember correctly the 5120 TEG is 120 W. We had 2 per tower site.

Price of propane would make a difference in decision. It varies here from
2.99 to 3.35 a gal. So $3,300+ per fill up is a lot, so what are you paying

The 40W is just there to
make up for lost solar time in the winter due to long days and snow. :)
The consumption up there is ~100+Watts. There are a few hams that tend
to use quite a bit of power.
There is more than enough solar for April-October.

I think we paid $1.60/gal.
Like I said before, once you get past 1000 gallons you get a screamin'
deal. I think we pay $7.00 (seven dollars) for the deliver fee too. It
is 9 miles up pretty crazy logging roads to get to the site.
