Aye Michael,
Living out in the sticks, though we are an exception, because we have the 6" HPG main running passed the cottage, there are few other economic options.
However, I believe that Steve has more panels than most, but I'm not sure of the windmills, all keeping those submarine batteries topped up with 24v going to an inverter.
No doubt the alternative energy could become a separate topic on this erudite forum!

Off to split logs, with my grenade, 14lb sledge and 4lb axe, it keeps me troshin'.
Good health, Bill
