This Demonstration compares daily solar energy yield obtained with five type of mounting systems: fixed (yellow) , horizontal (orange dashed), polar (blue dashed), vertical axis (red dashed), and two-axis tracker (green), based on solar data and latitude of the SunMine project in Kimberley, BC, Canada.

This graphic is provided in the context of the SunMine project in Kimberley. It compares the solar energy captured by five different solar panels' mounting systems:

• fixed at at an angle normally set to optimize the yearly energy yield,

• horizontal (rotating around an east-west axis),

• polar (rotating around an axis more or less parallel to the Earth's axis),

• vertical axis tracker ( a fixed-slope panel rotating from east to west to follow the sun's azimuth),

• dual axis ( following the sun in both directions (azimuth and elevation).

The graphic shows the total daily solar energy yield for the five systems, based on a clear sunny day, every day. Solar energy is composed of a varying proportion of direct and diffuse irradiation. The efficiencies of the trackers are greater on days with clear skies than on cloudy days.
