Glad you like the write up, and thanks for your kind words!

A few points in no particular order.

1. My current solar controller doesn't use a dump load (ie it's not a shunt regulator), which saves a bit of heat generation and is fine for solar.  I know that almost any non-trivial wind gen I add will need a shunt/dump regulator, but I'm really going to need someone to construct a low-power small turbine for me since my DIY skills are minimal!  Anyway, no hurry, since I'll only probably benefit from wind power in winter.
2. I am thinking of maxing out around the current controller to ~90W of solar panels, to have a chance of gathering enough power for decent lighting overnight, and to be able to have a chance to run some of the other kit, during even a fairly dull winter's day, and then probably bumping up the battery capacity to (say) ~200Ah to get one day's lighting-and-the-rest power at 50% discharge.
3. Beyond that I am definitely thinking of getting a separate set of kit for the higher-power loads, possibly even running at 24V to reduce current levels a little.  But if that was really going to run all the non-lighting kit all the time I'd need >500W of PV and >800Ah@12V (400Ah@24V) of battery for a few days' capacity and to avoid deep cycling.  If we get a loft extension done that we're thinking of then that's maybe were I could accommodate the panels since otherwise we'd have to cover half our tiny garden!
