Background
•Azimuth Angle – Angle in deg clockwise from due north.•Zenith Angle – Angle in deg up from horizontal.

Efficiency•Solar Panel effectiveness.•A ten degree or less offset will have 98.5% of max output.•If the angle is greater than ten degrees output drops dramatically.

1 Axis vs. 2 Axis Tracking
Single Axis Tracking•Less moving parts•Lower cost•Easier to adjust and build
Two Axis Tracking•Provides a higher solar panel efficiency•Can be setup in any orientation and find the sun

ObjectivesBuild a desktop solar tracker.Useable for educational and demonstrational
use.Able to run single axis or two axis tracking.Must be weather proof.Low power consumption.

Design ConceptsSolar Position:Uses a formula to calculate suns position.Micro processer uses formula numbers to
adjust position
Sensor Based:Cadmium Sulfide cells put out voltages.Micro processer takes difference.Micro adjusts position depending on data.

Sensor Based System
•Sensors sit in shaded areas.•Sun shines on one sensor.•Micro takes difference between two sensors.•Balances inputs by adjusting azimuth and elevation.
