I've got a 400W solar array on my cabin roof up near Pitlochry, paired with a 200Ah lithium battery bank and a Victron SmartSolar MPPT controller. Works brilliantly from April through to September, but come winter it's a bit grim — some days I'm barely pulling 20–30Wh out of the panels, and I'm having to be really careful about what I run.
Someone at a local agricultural show mentioned that a small wind turbine could be a decent supplement, especially at this latitude where the wind doesn't really switch off the way the sun does. I've been looking at the Rutland 914i and the Air Breeze Marine, both of which seem to come up a lot in discussions like this. Budget is probably around £600–800 all in for the turbine itself, not counting the tower and cabling.
My main concern is the hassle factor. The cabin is on a hillside with decent exposure, but I've read some horror stories about cheap turbines vibrating, failing in high winds, or just being noisy enough to drive you mad at 2am. Has anyone actually run one of these smaller domestic turbines through a Scottish winter and found it genuinely useful, rather than just a bit of a novelty?
