Read the excerpt from Catching Sun Rays. But before you can use the sun's energy, you have to capture it. To do that, you need a solar panel (also known as a PV panel). It's a flat black board covered with cells of silicon, the same material used to make semiconductor chips in computers. Those silicon cells change the sunlight into an electric current. They also use sunlight to heat water in houses and other buildings.

Based on the excerpt, which would a home owner most likely include in an action plan for using solar energy?
