Mounting panels near vertical will not eliminate snow accumulation entirely. But the amount of
accumulation is far less on the near vertical than on a a best summer angle, as demonstrated
by both setups next to each other here. It took some real work to clean inches off the 35 degree
angle panels, but just a tap on the near vertical panels might cause remaining snow to fall off. In
some cases so much of the near vertical panels was already clear, that first appearance of good
sun immediately finished the job. Panels were mounted enough feet above the ground that
accumulation of snow was no problem.
The other benefit here was panels gave more output using summer and winter angles, than a
single fixed setting. Bruce Roe
