I too looked into this a few years ago and was quoted 11 years to get my money back... Which didn't make financial sense at the time. Perhaps if it was more like 4 years I might consider it.
The UK has a lot of cloud cover so I do wonder if we should stick with wind power which is doing really well with the off shore installations.
Plus nuclear... For the rare times the wind doesn't blow.
I suspect it's not just the cloud cover. Looking at the map, it's quite depressing to note just how high up north even London really is. Berlin, Warsaw and Amsterdam are all similarly positioned. If we pan west along the 50° north parallel, the first reasonably large city in the American continent is ... Winnipeg.
We just don't get that much sunlight throughout the year to start with.
