A 5-year study performed at the Northern Alberta Institute of Technology involved a practical demonstration and measurement of power produced by solar panels oriented at various angles.
Multiple solar panels were setup at multiple angles, with one half of the tested panels left covered by snow and the other unobstructed.

Rather than setting up a large number of panels, an experiment to determine how much solar power is generated at various deployment angles will be performed.
Several Renogy 100 Watt panels will be set up at various angles to determine the amount of power generated at various times of the year.
The framing that will be used to setup the panels will be 2020 Aluminum extrusion.
90° facing south: Likely the most optimal deployment during the winter
69° facing south: Likely the most optimal in the summer
90° facing north: During the early spring and late summer, the sun is low on the horizon at night and high during the day. So a north facing solar panel would capture power overnight.
For any equipment that is deployed in the field off-grid, making the absolute most use out of the available 24 hours of daylight is necessary.
As a result, it might make sense to deploy solar panels that are capable of solar tracking.
One of the ways that it might make sense to deploy solar trackers for remotely deployed equipment involves a relatively simple design.
Rather than elaborate flower shaped solar tracking arrangement like this, what if several poles were installed on the ground and panels were suspended via aluminum aircraft cables connected in the centre?
Electric motors could be used to orient the solar panels at the exact optimal angle for charging during the day in multiple directions by drawing in the aircraft cable to accomplish specific angles.
It'd simply involve setting up four poles with a single or multiple solar panels in the centre.
