Someone I know put solar panels on his house around ten years ago and there are often times where he is paid by the Grid for his surplus energy.
He is very pleased he made the investment and it was paid off years ago anyway.
It's a pity the Tories removed the subsidies for solar panels, more shortsightedness from them.
Here is a list of some of their idiocy which reached a peak after they booted out the Lib Dems who were very good on this issue and drove much of our progress on it: https://www.theguardian.com/environ...-green-policies-killed-off-by-tory-government

And their failure on nuclear power:

To be fair, the price of solar is the cheapest it's even been. I don't think it actually needs subsidies any more, most properties can be outfitted with all the panels they need for £5-£6k (if you exclude batteries etc). Capitalism and competition has driven prices down rather than subsidies.
