Easily adjustable tilting Solar Panel Mounts

I'm looking for permanent install solutions to for a single solar panel at a time install and the ability to tilt without having to undo hardware and adjust. Ideally, something like a skylight or casement window crank control for a panel that will be installed 8 or 10 feet up from the ground. The other requirement being cost - thus the manual adjustment. The panel will also be installed on a flat surface. Let me know what you have come across - Ive found mostly adjustable mounts meant to be positioned and left in the same state or have a high touch requirement to change.
