To broom the panels or not?

Bit of a project to get on a 10' flat roof and scrape the snow off. 1/3 of the snowfall has already fallen off the panels. It is 32 degrees and cloudy with no real change expected. A wide broom would knock the snow off. An ~20 minute project. Safety level? Not good. Not bad.

We are running close to 10 days with no direct Sun light, might be trying to beat the record of 4 years ago.
I have had some bright days, where I gained more than I lost, but haven't had a 'full battery' in 10 days now. I was at about 75% peak the last couple days. Rain and snow tonight.
On the Plus side I got to stress test my wood rack for my solar panels with 18" of snow. She came through with flying colors!
- Assorted other systems, pieces and to many panels in the closet to not do more projects.
If snow was a bigger issue here I would probably construct a "staircase" to the roof. Deserts usually have little snow.
Snowfall does present an argument for steeper panel angles.
I am available for custom hardware/firmware development
