Theoretical question effect of frost snow on panels

    A question, a hard frost this morning in Cork and there was frost on t panels. It cleared quickly but a promise of snow tomorrow. This is very rare in Cork city but 2009 and 2010 were Flipping freezing for weeks. What effect if any does really cold weather have, and if we had sustained snow fall would you brush it off the panels

    Depends on your objectives really - if you want any sort of power then you could go clearing it off. As they are typically black surfaces then they tend to shed the frost and light snow quickly enough, but not if it's deep.

    I did wonder if they were self cleaning and would slide off + any sunlight would heat them up and it would melt. The angles they are fitted makes it harder for snow to grip.

    When it snowed last winter I had a bit of an accumulation on the panels on my roof after a while, but as @greasepalm alludes to, even as the snow was falling once it got to any decent thickness chunks actually slid off (I heard the thunk from inside and was wondering what it was until I copped the pile outside the door).

    With a 2 storey semi-D I won't be going up to clear snow off mine, but IME frost is cleared pretty quickly if there's any sun to be had, and snow doesn't last too long on smooth inclines in the same conditions if it's not shaded.
