[RE-wrenches] De-icing panels off grid

[toddcory at finestplanet.com]

Passive works best. In big snow country here, I learned the hard way to only do pole mounts... and set the angle steep in the winter. The snow slides off and all is fine.

[ https://glasscareexperts.com/solar-glass-protection/ ]( https://glasscareexperts.com/solar-glass-protection/ )I’ve never tried it but just heard about these people. From the bio they are the original makers of rain X, but they customized a product, several of them, to clean Pv panels and they also mentioned it can help to shed rain and snow.
By the way, Rainx is not  approved for such an application.

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,Howie Michaelson
