Snow Clouds Worst Day for Solar PV Generation

We've had our worst day so far for our solar panels generating electricity. It looks like solar PV Generation is very badly affected by snow clouds even if it isn't snowing!

The worst day for solar PV generation so far meant that we only generated 0.2kWh today, a mere fraction of other cloudy days and a miniscule percentage of a sunny day.

Solar PV electricity generation on snowy/cloudy days

It appears that the very dense clouds that bring snow also shield a lot of the solar radiation meaning that the panels produce very little electricity in such dark conditions. Even at peak generating time today between 1200 and 1400 we had over an hour with 0 kW produced which is the first day this has happened since installation.
