It sounds like you’re worrying that raising the height of the roof, by adding solar panels, will cause the snow to travel further horizontally when it leaves the roof, compared to its current behavior.
The height impact is minimal. Instead it’s about friction: panels are very smooth compared to shingles, and notoriously avalanche-prone. The faster snow is moving when it leaves the roof, the farther from the roof it travels horizontally.
aha, that makes excellent sense! How much increased snow travel are you expecting based on your observations of the existing panels, and would affixing something high-friction like a fishing net over the panels reverse this?
