An interesting experiment that we did in class the other day was determining what affects the efficiency of solar panels. The variables we tested were distance the light was from the panel i.e. brightness, and the color of the light hitting the panel, simulated by placing translucent strips of plastics of different color in between the sensor and light source.

The results showed that more volts were produced when the light was the brightest (closest to the sensor). Additionally, out of the 3 colors we tested (red green and purple), green light produced the highest voltage at .40 followed by purple at .35 then red at .32. Unfiltered light had the most with .47.
