I am very concerned just about global warm, 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 within your answers) and I'm wondering currently how much it costs to install solar cells and how long it will thieve to pay past its sell-by date.

Yhis is a very complicated query. I won't be able to answer it, but will bequeath you some things to think roughly speaking.
First of all, I enjoy a solar system. I installed it because I had adequate money, and it was superior on my priority list than anything else. My first desire was to do it within the name of reducing my impact on the spirit and ecology situations.
The second goal be to provide enough power to keep hold of from buying power from the utility. I went overboard, and bought a system much bigger than I needed. As a result, and due to some change in my vivacity (I now live alone) I own been competent to not only provide adjectives the electricity I needed, but to heat the house next to electricity instead of gas. I still have a gas river heater. In California, if you use more electricity than you form on any given day, you can nurture electricity to the utility. If you are using more than you are making, you can take power from them. At the cease of a year, you pay for any amount you used over what you put posterior in. They give the name it net metering. In adding up, I pay a small monthly charge for the right to use the utility's system.
There are a great various things to consider when thinking of installing photovoltaic solar. Think of the roof. If it will have to be replaced contained by a year or so, it might be best to do both at once, or wait until time to reroof. If the system is to be mounted on the roof, verbs about adjectives leaks. They hold to make like mad of holes when mounting the panels. Mine are over the garage and an overhang, not the attic. I did own a leak within the garage. Not nearly as big a deal as if it be over the attic.
At today's costs, it would take frequent years to break even on cost. Perhaps by the time you would want one, the costs of systems will have gone down. Surely the cost of power will hold gone up. Since my system cut both my lighting and heating bills, my system will pay envelope for itself in a shorter time. Also I will get rid of this house in a few years. The system will make the addition of value to the house, so that help.
So when you are deciding, first set down your goals. Write down basically what you want the system to do. Then decide what you are ready to do without within order to enjoy the system.
If you maintain your present attitude something like the environment, I don't think it will business what you study in college. That is, unless you plan to work surrounded by the area of environmental admin. You will want to pick the kind of career you are interested in. If you are resembling my kids, you will change your employment goal more than once, as you mature and silver your interests. Nothing wrong with that, as long as you settle on something. Let your parents surrounded by on your thoughts and goals. I hope they make a contribution you a free hand, but profusely of good suggestion too.
I didn't mean to write a book, but your cross-question was a confront.
