I did a project with them on the Isle of Skye with an LE-v150 extreme for an off grid telemetry system. Unfortunately despite being in a rather windy spot it never really did generate anything and we ended up going for a bigger solar panel to get enough power.
Despite providing wind data from the weather station sat directly above it never did get resolved. Shame really as they were knowledgeable and the product well built.

How much power?
used to (kind of) know a guy who lived on one of the islands off the top of Scotland, for the life of me I can't remember the name of it
he worked on the ferry that went back and forth.... proper island, no electric/water etc. etc.
he and the other people living there had great success with with turbines... but they always said solar was better.... it;s fit and forget... no maintenance, no shutting it down or lowering it in a storm etc. etc.

Indeed, but it doesn't work at night or in fog...
And the cash.
without the feed in tariffs might as well get used panels, which are pretty cheap on ebay now as big solar farms swap their panels over to newer more efficient ones
I'm just waiting to get my new roof on at work then I'll cover everywhere and anywhere I can
some roofs will be shaded by others, but if I can split the strings so a line of panels along the top is on one string and line under it is on the next string, on and on like that.... hopefully the top string with no shading will produce well, and the next one will start producing as the sun rises (or falls) and the shade passes over the string all at once
(I don't think I'm explaining this well) - if I can line the panels up with the shading - the shade should move down over the strings evenly
once my current contract runs out I'm looking at a multiple £thousands/week increase so need to do everything I can

Thousands a week increase? I think the news hype has mislead you a little?
My 4 (ok 3.6 or whatever) makes a tenth of summer output over the winter. With a big old battery and inverter I would need four times that (rough guess) to keep offline in the winter, so 16kW might do it? Nah, the battery will still go flat at times...

It's incredibly site dependent. Our 5kw almost makes 10MWh / year. But never quite. That'd be £5k a year at new price cap prices or £1000 a year at gas price. Some Hebridean ones of the same model apparently make more than twice that. Obviously you'd struggle to use it all but, in a windy spot, with a poorly insulated house, and current prices, it can make sense.
Anything that fits within the curtilage of the house though rules though, forget it.
Does require annual maintenance too. It's a lot harder life than a static panel with no moving parts.

I think he’s talking about business premises
yes, as above that's at work, where the bill is already £thousands/month
I'm sorry, a 5kW PV making 10MWh a year? No way Jose?
On a good year, my 4kW system will make 4000kWh, or 4MWh, but its rare.
Imread this again - you're talking about a wind turbine - now I'm with you. Sorry, needed to read back for context.
