Solar panels are used to create and supply electricity as a component of a larger photovoltaic system in commercial and residential applications. The past week we had the opportunity to discover further how solar panels work. During this lab experiment we had small panels and flash light. We had to flash light to the sun panel to see how much energy this would generate. By doing different runs each at a different distance between the flash light and the sun panel we concluded that when the light was shinning closer to the sun panel higher was the voltage created. This conclusion was as we anticipated.

Later we did the same procedure using different color filters which the conclusions amazed us a little. My partner and I discovered that by using no filter at the same distance the voltage was higher, which we expected. But what shocked us was that if the filter was darker lower was the voltage. In the graph below we can see how the pink and orange had almost the same voltage and with the green it had a lower voltage, all four, including the non filter run, were done at a distance of 10m.
