i depends upon how large the plant gets naturally.
i.e. how heavy and how strong the vines are. if they
will self-support or not. for the large grape vine i
had out back i put in poles in cement and then attached
2x4s and cross pieces to hold all the weight. what is
the growth habit? if it spreads out as it grows up
or does it just go up as high as it can and then
spreads out at the top.
also you have to figure your winds and the cross
section to the wind or any protection from the wind (like
if it is closer to the house or in a corner or there are
some blocking trees), etc.
hmm, likes a bit of shade and moist and well drained soil.
that's going to be a tough sell in your area. may need
to have a lot of mulch to keep it going.
Have you ever considered putting in a windmill to generate electricity? Dep
ending on the size of your property and zoning codes, you might be able to
get your local utility to install one that you could tap off of. I've been
thinking of building a windmill for about 20 years now; might get around to
in in the next 20.
i only need a small amount of backup (so i can shut down
the computer in a good state) and to run an LED light if i
need one. as it turns out the computer battery back up
will do those things so i don't need a separate battery.
solar panels would be nice, but in the scale of things
water heating from sunlight is the best investment to
do at first. you can get hot water for a lot less than
full electricity replacement and then using solar to run
the pumps you can also use the extra heat in the winter.
where you are at with all the sun it pays for itself pretty
well. then once you have that up and running and it has
covered the expense of putting it in you can expand the
panels to supply the rest of your juice. stay on the
grid and don't bother with batteries if you can avoid them.
chances are that in the future you can have that all
incorporated in your car being plugged in so you won't
need two battery packs.
the bare frame won't catch nearly as much as the plant
will if it has much in the way of leaves.
if you anchor the ribs well enough a tripod is very
stable against the wind. that is why i said teepee as
it is just more triangles/ribs...
