ManucciaMr. Peter WihlGTA: Jason Woytowich, Bassam NoamanAbstractThis report discusses the final design for a Sun Tracking Platform thatwill be used to direct solar panels in the appropriate direction to follow the Sun. This feature will enable the solar panel to receive maximum sunlight and thereby collect more energy. The Sun Tracking Platform will be compared with other existing products in the market. The Sun Tracking Platform will contain similar features as the existing products yet it will be sold at a lower price to increase the market size. Since the Critical Design report, a new section has been added to the report, Implementation Plan. The report discusses the implementation details and a preliminary mechanical package design of the product. iiTable of ContentsAbstract..............................................................................................iiList of Figures....................................................................................ivList of Tables.......................................................................................vIntroduction........................................................................................1Overall Product Requirements...........................................................3Functional Requirements...............................................................3Non functional Requirements.........................................................3Overall Product Specifications...........................................................4Approach to Overall Design................................................................5Theory of Operation........................................................................6Design Plan.........................................................................................9Hierarchical Breakdown...............................................................10Modular Specifications.................................................................15Implementation Plan........................................................................27Key Component Selection.............................................................28Preliminary Mechanical Design........................................................34Testing Strategy...............................................................................37Overall STP...................................................................................37Overall Sensors Module...............................................................37Control Unit Module.....................................................................38Power Sub-system.........................................................................41User Interface...............................................................................41Critical Parts List..............................................................................42Time Estimation................................................................................42Labor Costs.......................................................................................45Economic Analysis............................................................................46Module Matrices...............................................................................47Overall Sensors Module...............................................................47Control Unit Module.....................................................................49Sensor Analyzer.......................................................................49Azimuth & Elevation Control...................................................50Prototype User’s Manual..................................................................51Status Report....................................................................................53Summary and Conclusions...............................................................54Qualifications of Key Personnel........................................................54Resume.........................................................................................54Transcript.....................................................................................56Intellectual Contribution..................................................................57Bibliography and Citations...............................................................58References........................................................................................59iiiList of FiguresFigure 1 - Size and Dimensions Diagram..............................................4Figure 2 - Context Level Diagram.........................................................5Figure 3 - Top Level Block Diagram......................................................9Figure 4 - User Interface Diagram........................................................9Figure 5 - Decomposition of Level 0 & Level 1...................................10Figure 6 - Placement of sensors..........................................................11Figure 7 - Current to Voltage Characteristic.......................................11Figure 8 – Sensors Module Decomposition.........................................11Figure 9 – Control Unit Module Decomposition..................................12Figure 10 - Mechanical Arrangement..................................................14Figure 11 - Power Sub-system Decomposition....................................15Figure 12 - User Interface
