Using Solar Panels for Energy

Video Transcript

"OK, we talked about catching the sun, but you can catch the sun in different ways. You know, the sun is really the main reason that we exist on this Earth, because it provides us with energy. And this kind of solar cells us see here, is a different kind that we have on our roof because this is not one cell after another. That's really always one piece, and it's producing electricity even when it's shady, even if the sun is not full shining, these cells can produce electricity. The bad thing on it is that these cells are not quite happy when it gets too hot, so you really have to have some kind of air going around it. And in high summer, these are not that perfect, but they work. And a size like this you see here is producing 45 watts an hour, and at the moment the sun is shining, so it will produce full 45 watts an hour. And when you buy these at the local store here, you will pay around 200 dollars for it. So, you can calculate that you spent 200 dollars, but you get as long as the sun is shining, the 45 watts an hour out of it. So, it really pays of in not a too long of time, but it's not as cheap as when you get your electricity from the grid. But we use it to charge our car battery sometimes. For the golf cart it's perfect to charge it. So, it's a mobile system. You get, with the price, you get a lamp for it so you can use it to, for your tent, or when you have a hut out there somewhere where you have no electricity. You put these there and a little golf cart battery, and when you come there, you have light, you can run your radio or your television. So, it's a nice equipment to show people that even a small size, and easy to install thing can help to catch the sun and to save energy."
