The existing mount for the panels could be improved by extending the bottom of the steel pipe support.
The addition of two feet to the bottom of the steel pipe would improve maneuverability. The panels are positioned near the bottom and run into the ground when the panels are rotated to the extremes of position.
This limits the amount of afternoon sun the panels can receive.
Another possibility: add mirrors to the sides and/or top to increase the amount of energy absorbed. This would increase the energy suplly in Winter when the sun is low in the sky at it's zenith.
See the YouTube video for details.
