That's the basic question -- "what's the pipe size?". Anyone who wants to hear additional ranting about alternative energy may keep reading.
I'm designing a wind-generator/ battery/ invertor/ grid-tied system for my house. I'd go off-grid completely, but I intend to install, at first, just a sufficiently robust back-up power system. Then, I will start adding wind generators as they become economically pheasible, until I can actually generate the, say, 2000 kW-h/mo that I would ever use (worst case).
IMHO, the subject turbines offer the best of all possible worlds, in terms of unit weight, power output vs. wind speed curves, cost/kW-h -- you name it. Also, I like the idea of using (not tiny) but multiple small wind generators (like the subject class), rather than a single big one. There's two reason for this, mainly -- 1) the small ones are very light-weight, comparatively, and therefore require less stringent mounting requirements per each, and 2) if my (hypothetically) one big Genny fails, I'm stuck with no generation cpacity! But, if one of a few smaller models fails, I still have something left working for me while I repair/replace the broken one.
I should be fair. There's a big difference (as I understand it thus far) between the Lakota's (which output DC voltage) and the bigger, heavier units, which output AC voltage, is that, given the DC power-transmition problem, the generators I like will basically cause me to have to build a "battery shed" where I'd keep my batteries and invertor, and finally, from there, send 240 VAC to the house, something on the order of 500 feet away. So... anyone reading this probably knows how challenging it is (if you've tried) to design a suitably-sized and cost-effective alternative-energy system for your home; I'm an electrical engineer and can autoritatively say that it's a significantly challenging overall optimization process.
Back to being fair, other brands and larger gennies have their merits and may likely be best for a given situation. Thanks in advance for any comments or suggestions.
