Ice, Ice, PV!

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the temperature of the panel and measure the voltage output. They plot the power output versus time as the panel's temperature changes.

Instructional Ideas

  • Spend some time with the class to make sure they understand the variables in the equations
  • Alter the experiment to measure the temperature at the same time pupils read voltage to plot power versus temperature
Classroom Considerations

  • The class members should be familiar with electrical circuits
  • Individuals need to be able to solve equations and rearrange formulas
  • The fourth in a series of eight resources
Pros

  • The answer document provides the mathematical steps needed to arrive at the final solution
  • The handout provides the directions so individuals can conduct the experiment with little explanation
Cons

  • None
