Duh!! The latitude of UK is 55 degrees North. That is 10 degrees farther north than Marquette, MI! Marquette is on the shore of Lake Superior, and damned cold. Sunlight comes in on a shallow level, even on June 21st.
What kind of mutton head expects solar power to work there?
We're at 48 I think... And solar works here... And I have friends up in Alberta and BC who are off-grid.
General rule of thumb is a third to twice as many panels, and twice the batteries called for, depending on your usage... And with that, STILL having to fire up the jenny from time to time... But solar does work.
Where it doesn't work is at the utility level, and I don't think it ever will. It is too ephemeral to be relied upon. Maybe that's different down by you, I dunno.
But here, in a distributed fashion, it would be a good supplement... backstopped by grid or jenny.
If a house can be self-sufficient say, 50% of the time in a year, that's a whole lot of weight taken off the grid, if every house could make that brag... Even 30% would be worth looking at.
That's something like 8-10 panels here, and 4-6 batteries, with the grid handling 220v.
That is probably the way forward for solar and wind. Distributed... taking weight off the grid at the end point.
