The chapter is appropriate for students in grades 6 through 12.
After completing this chapter, students will be able to:
- monitor the capacity of currently operating solar panel installations; and
- predict how much of a school or home's energy needs can be supplied from solar panels.
Examination of the online data and graphs can be done in groups. Three or four students can be assigned to a location and a time interval and asked to interpret their resulting graphs. Next, groups can be brought back together for a classroom comparison and discussion, especially if a smaller time interval can explain anomalies in data from a larger time interval at the same location. The data from Parts 2 and 3 can be used, or any data that seems complete and useful. Not all datasets are good examples, as the equipment used to monitor them may have broken and gone un-repaired for days or months, in some cases. The Soltrex site has a summary of all the data for each of its sites at the bottom of the page with its "system details". This provides a useful filter for good data.
The following National Science Education Standards are supported by this chapter:
8FSPSP5.1 Science influences society through its knowledge and world view.
12ASI1.3 Use technology and mathematics to improve investigations and communications.
12EST2.4 Science and technology are pursued for different purposes. Scientific inquiry is driven by the desire to understand the natural world, and technological design is driven by the need to meet human needs and solve human problems. Technology, by its nature, has a more direct effect on society than science because its purpose is to solve human problems, help humans adapt, and fulfill human inspirations. Technological solutions may create new problems. Science, by its nature, answers questions that may or may not directly influence humans. Sometimes scientific advances challenge people's beliefs and practical explanations concerning various aspects of the world.
