This is what we got done to the back roof of our house today. (Why are the curtains on the upstairs bathroom closed, Mr Life?) The solar panels cost lots of money. Hmm. And they're not even pretty.
Now all we need is for the sun to beat relentlessly down all day, every day from now on and we'll get lots of free electricity. Bound to happen, don't you think? This is Scotland, after all. Look - can you see that faint shadow cast on the left by the tv aerial?
