Thanks for the replies.  A neighbour has a PV system and he generates about 3000kwh /year.  However as most of my electricity is used over the winter I am not sure how economical this system will be.  I will have to do some calculations.

Is the initial cost of PV much more than ST?  I like the idea of PV, but it has to make financial sense for me. 

What a great forum.  Can anybody recommend any PV or ST installer in Scotland?



Like you I'm off the mains gas grid, I've had ET solar thermal for over 10yrs and Solar PV for 5yrs.  I've had no major problems with either but if I were in your position now I'd be spending the money you've allocated for ST on enhancing a PV system with battery storage. Given that your main electricity purchases are over the winter period I would look at a storage system that allowed you to time shift, so during low generation period in winter you can at least  store off peak electricity to consume during peak periods.  The next gen Tesla Power Wall will be able to do that AFAIK....
