My sentiments exactly.
I'd say you're already monitoring your power usage, so take a good look at your
peak usage, whenever it is during the day, and for how long, while you're still
on the generator.
That is critical for determining what should be your solar maximum power
generating capacity, for whatever storage you have in mind (plus 10 percent),
and how much average sunshine you get per year.
An 8 panel 2kW system seems to me a bit under powered with the modern need for
electricity to run a fridge, stove, washing machine, kitchen appliances and air
conditioner.
Don't forget that panels don't actually produce what they're rated for, even if
you're using a sun-tracker controlled bank of panels mounted on a swivel.
If I was in your situation, I would be seriously considering a 'smartflower'
system. (

quote from your electricity supplier, but the power is yours, not the
electricity company's, which would still charge you for power usage.
Yep, huge outlay, but on a hill top in New Hampshire, it may well be worth it in
ten years' time.
(love it, but they're not selling in Australia - yet. There's no outlet in New
Hampshire, either, but they're in all the states surrounding you)
If you're mounting your panels on the roof, please, don't waste any time getting
that small hydro plant installed (specially for night-time use), because it will
be only then that a 2kW system would suffice. 5kW would be better, if the hydro
is going to be a "when I get round tuit' event
I've been an electronics technician for 50 years. I installed 20 panels (rated
maximum of 5kW), driving into a 3kW inverter six years ago, but being roof
mounted east (8), north (4) and west (8), only just reach 3kW in the middle of
summer. I wrote my own PC program to monitor the Solar output 24/7.
I've just Googled Mink Hills. Pretty green where you are!! Are you near
Cunningham Pond, or closer to Warner?
