Snow and solar.

[lostinthelight]

Physics being physics, I presume that there must be at least some heat generated within the panels (sort of similar to what bernard has suggested) - does that not help to melt the snow?

For the panel to produce heat would not the panel need to be producing power which it doesn't because it shielded by the snow?
I am fortunate to have my panels on a single story shed where they can be brushed or hosed off

Yes, and that could obviously be a problem if a lot of snow falls fairly quickly. However, as has been said, snow, particularly in thin layers, is by no means a 'total light blocker'..

Now back to full output, not much I can do about snow, but wait for it to melt.

How does it affect the National grid?

I stated suspect the numbers are so small in the winter it’s not important at a national level

Quite. I made that point at the start of this discussion. I would imagine that there are probably some UK Winter days when solar generation in the absence of snow is almost as low as it would be with snow.
