[RE-wrenches] De-icing panels off grid

[Howie Michaelson]

Has anyone successfully used heat panels or cables to melt iced-over panels
(ie. without damaging the panels)? In heavy snow country, or over periods
of freeze/thaw when pelty slushy snow sticks and freezes to panels, it
would be nice to have a safe method of clearing them, especially off-grid.
I remember discussions of the futility of backfeeding panels to heat them
up to accomplish the same, but not about heat tape or pans that might be
worth trying.
Thanks,
