Our next task was to make a fan move using just the solar power, and to see if it was possible from different distances. We used different numbers of solar panels in the experiments. First one, and then two, and some boys got to four or five panels, seeing how much energy was required to make the fan move. The professor told us where and how solar panels would be used best, and even in situations with limited numbers of solar panels how to get the best out of them in relation to the sun, with compass directions and angles. It was a great lesson; it taught me a lot about how solar panels really work. I was very interested, down to the molecular level and how the mechanics work.”
