I would say 10% of the homes in my estate in Derbyshire have rooftop solar. We haven't gone for it yet because I still think the cost is too high. It might work out when electricity gets even more expensive.

Is there any truth to the climate sceptic claim that solar in the UK can’t generate useful power with our bad weather and cloud cover? I always said that it’s not like Germany has better weather but they have tons of solar. However it would be great to have an answer from the UK.

It definitely generates useful amounts of power, especially in the summer. The problem is that we still need gas plant, and the distribution infrastructure ready for the rest of the year when it isn't so effective.

In the last year, 2.11% or 308 MWh of our electricity came from solar: https://app.electricitymaps.com/map/zone/GB/12mo/monthly

By way of comparison, that same source shows Germany generating 2.16% (527 MWh) of its electricity from solar so its pretty similar: https://app.electricitymaps.com/map/zone/DE/12mo/monthly
