I installed 26, 390 watt bifacial panels. Since it snows so much here, it was important that they also tilt to vertical to shed snow. I used two 4x4 ground contact timbers embedded in about 350 lbs concrete.
The vertical tilt really helps capture reflected sunlight from the snow, giving me 12,000 watts often during sunny January and February days from a 10,140 watt nominal array.
