1、Solar Solar Tracker TrackerDavid Crowe, Jeff McCormick, Joel Mitchell,Thomas Stratton, Jeff SchwaneDecember 15, 2005Duke University Smart House Pratt School of EngineeringAbstractThe Solar Tracker team was formed in the

2、 fall of 2005 from five students in an ME design team, and a Smart House liaison. We continued the work of a previous solar tracker group. The task was to design a prototype tracking device to align solar panels optim

3、ally to the sun as it moves over the course of the day. The implementation of such a system dramatically increases the efficiency of solar panels used to power the Smart House. This report examines the process of desig

4、ning and constructing the prototype, the experiences and problems encountered, and suggestions for continuing the project. 1.IntroductionSolar tracking is the process of varying the angle of solar panels and collectors

5、 to take advantage of the full amount of the sun’s energy. This is done by rotating panels to be perpendicular to the sun’s angle of incidence. Initial tests in industry suggest that this process can increase the effic

6、iency of a solar power system by up to 50%. Given those gains, it is an attractive way to enhance an existing solar power system. The goal is to build a rig that will accomplish the solar tracking and realize the maxim

7、um increase in efficiency. The ultimate goal is that the project will be cost effective – that is, the gains received by increased efficiency will more than offset the one time cost of developing the rig over time. In

8、addition to the functional goals, the Smart House set forth the other following goals for our project: it must not draw external power (self-sustaining), it must be aesthetically pleasing, and it must be weatherproof.The

9、 design of our solar tracker consists of three components: the frame, the sensor, and the drive system. Each was carefully reviewed and tested, instituting changes and improvements along the design process. The frame

10、for the tracker is an aluminum prototype for solar tracking will be the foundation as they move forward in the future development and implementation of this technology to the house. 2. Defining the ProblemThe project was

11、 to complete the “REV 2” design phase of the solar tracker to be used on the Smart House. While the team was comprised of members from the ME160 senior design course, the customer for this project was to be the Smart Ho

12、use organization. Jeff Schwane, a representative from the Smart House, was our liaison and communicated to our group the direction Smart House leadership wished us to proceed. At our first meeting with Jeff and Tom Ros

13、e, the following needs were identified: 1. Track the sun during the day2. Use no external power source3. Weather proof4. Cost effective power gain5. Must look good6. Solar panel versatile i.e. can fit different types of

14、panelsWith these needs in hand, we constructed a Quality Function Deployment chart. This chart can be found in Appendix A. The QFD showed the major areas of concern might have been: number of panels/size of panels, int

15、ernal power requirements, motor torque required. At our first meeting we were also able to set up our goals for the semester. Having a working prototype capable of tracking the sun was to be the main goal for the end o

16、f the semester, but we soon found that in order to accomplish this, we would be forced to omit portions of the design criteria in hopes they would be worked out later. This would result in the optimization of platform s

17、pace on the roof to be irrelevant, with our goal being to have one platform track. It also led to the assumption that our base would not need to be tested for stability or required to be fastened to the roof. With an i
