My daughter is entering her third science fair project on solar panels. The first, she determined that there was an ideal tilt angle of a solar panel, facing True South on a particular clear day, that provided optimum electrical output, as compared to other tilt angles. The second, she determined that a tracking solar panel (adjusted manually by hand) provided optimum electrical output, as compared to a static panel that had zero degrees tilt and was facing True South. For her third project for 9th grade, she is currently challenged to construct a tracking solar panel that is auto-operated by motor action. This way, the project can be self-run while she is at school. Multiple whole days, regardless of cloudy or clear weather could be studied. My daughter has not learned how motors work yet. It has been a successfull struggle for me, getting her to finally understand AC and DC concepts. And, no, the concepts don't include the band. Haha. Whatever is constructed though has to be something very, very simple. I do know that two axles, each driven by a motor, are a must. The actual design and the programming of the motors is gonna be tough. I have learned that in 9th grade, the beginning of high school, computer programming is a requirement. So maybe the programming knowledge can be tied into this idea somehow.
