| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 99 === In order to improve the practicality and the widespread of solar electricity generation system, this paper applies TRIZ (Theory of Inventive Problem Solving) theory and tools to create a solar energy power supply mechanism with sun tracking system that can be attached to the windowsill, where the user from indoor can manually operate the joy stick to control and perpendicular the solar panels outdoor to the right angles to the sunlight and enhance the effectiveness of the solar electricity generation system. This study first collected related literature on solar energy systems on rooftops, to probe into analysis of the driver program of the sun tracking system by using tools such as Technical Contradiction, Physical Contradiction and Substance-Field Analysis of TRIZ inventive theory to bring up a series of inventive programs. In order to verify the practicability of the programs, this study analyzed the astronomical sun tracking system program by using Visual Basic programming language through graphical user interface to further establish a database on the corresponding solar orientation from any spot on earth and also designed an interface to calculate the locations set by the system that required adjustments and corrections on ranges and angles within a day. The user only need to input the latitude of the location and the date to get the required hours of the sun relative to the user’s location of the incident angle and azimuth, and then manually adjust the two axis, so the solar panels perpendicular to the angle to the sunlight to enhance the effectiveness of the solar energy.
The study shows that the manual astronomical sun tracking system program of the inventive programs can generate roughly 12.74W of power, the original institution’s stationary mechanism can generate roughly 10.05W of power, which confirmed that the inventive program in this study indicated an enhancement of 26% in power generation. The power generated through the manual astronomical sun tracking system program of the inventive programs can also provide general electrical power supply to general electronics and be used as outdoor power supply.
Key words: Solar energy, Sun tracking system, Solar energy databases, Astronomy, TRIZ inventive theory
