Snow sliding off slick solar panels

[Jerry Simon]

On a slate roof, we use snow-dogs (a regional term I'm sure) to break-up sheets of ice or snow snow they don't slide-off the roof in large pieces and cause damage or injury.

How would one prevent snow/ice sliding concerns for the panels on the front part of this garage roof?

[Jim Katen]

We used to call them snow dogs in New England, too. 

It doesn't look steep enough to be an issue, but I'd probably devise some kind of extra-high snow dog to mount on the roof just in front of the panels.

The folks I know with solar panels keep them clear of snow at all times -- they seem to work better.
