Variables Affecting Solar Collectors

Figure from experiment 25 from Renewable Energy with Vernier


Sunlight is composed of photons or bundles of radiant energy. In photovoltaic panels, that energy is converted into electricity. In a solar water heating system, sunlight is converted into heat in the solar collector. When photons strike a solar collector, they may be reflected or absorbed. The more photons absorbed, the more efficient the solar collector can be. The ability of a solar collector to absorb photons is affected by many factors, including its color.

The KidWind Solar Thermal Exploration Kit allows you to test how different variables affect a solar collector. For this experiment, you will pick one variable and test it.


  • Use a Surface Temperature Sensor to measure the change in temperature of the water in a solar collector.
  • Create a plan to test a variable that affects solar collectors.
  • Collect data and draw conclusions based on results.
