The Effect Of Clouds On Solar Power

By Paul Homewood

 

There’s a good article on TCW about the giant new solar farm proposed in Cambridgeshire:

We are naturally all familiar with the intermittency of solar power in terms of seasonal and day/night. But Julian Flood also raises the issue of reduced generation during cloudy or foggy weather.

I have heard this idea pooh poohed by renewable enthusiasts, who argue that it makes little difference – something about photons apparently!

However a look at this weeks solar power data shows this is nonsense.

The last three days have been sunny, but Monday and Tuesday were rather dull, though certainly not foggy here.

As a result solar power, which peaked at over 4 GW Wednesday to Friday, did not even reach 1 GW on Monday.
