How Much Does It Cost To Install Solar Cells In A Typical American House, And When Will It Be Paid Back?

I am very concerned about global warming, and when I grow up (I’m fourteen), I plan on helping to solve the world’s problems by looking into environmental research (college course options would be nice to include in your answers) and I’m wondering currently how much it costs to install solar cells and how long it will take to pay off.
