See the Sun, Measure the Power

Overview

Objectives/Goals I wanted to find out if using mirrors to reflect more sunlight onto a solar panel would cause the panel to produce more electricity? Methods/Materials I used a solar panel that is used in a car, 4 one foot square mirrors, a milti-meter that can measure volts and amps and a battery cable that plugged into the solar panel. I had myself and up to three other people holding the mirrors so that sunlight would be reflected over the entire panel from each of the mirrors. I recorded the maximum amount of amps/volts that occured during each trial. Results I found that using mirrors to reflect more sunlight onto a solar panel causes the solar panel to create more electricity than sunlight alone. Conclusions/Discussion During the experiment the number of volts nevre exceded 22 and it stayed there for most of the trials, the number of amps went up however with each mirror added, that is why my hypothasis was correct, if one half of an equation increases, the number it equals also increases.
