Hi Armster,
90% of our hot water comes from evacuated solar tube type collector, & have had wind generators in the past, so for what it's worth...
I agree with KB, they are not yet seen as a sales point, need managing to get the best from solar panels, ours 'top-out' by midday most good days, by which I mean the temp on tubes gets to 140 deg C too hot to pump so if lots of water used late in day tank cools down but can't be topped up until temp drops to under 105degs, by which time running out of daylight, need to do washing ect. in morning..
My reason for fitting was to pay for my lifetimes hot water 'up front' whilst earning well so lower bills when retired & energy costs much more (as it surely will).
As for wind gennys, my last one 'took off' during gales & landed in neighbours garden, boss lady said no more...
Ugly, noisey, need to get agreement for 2 way metering as none large enough to stand alone & only generate spare energy over night, when your load less than 1kW, don't think yet worth it but may be one day, regards SPARX
