> Depending on where you live a system that allows to manually change the tilt of your pannels once per month could be nice. You get a free 5-15% boost, where I am in Europe the optimal yearly tilt is ~40 degrees, in peak winter the optimal tilt of ~70 degrees would shed snow much more easily.

Yup, that's what I was referring to as a tilting mount in the original comment, a pivot and tracks to tilt the panels up/down to set them at whatever's optimal for your latitude and time period, or completely vertical if you're in a snow-heavy region.

The necessary engineering might not be worth it anyway, given current panel prices, unless space is a bit of a premium.
