In general our hypothesis was correct. On average, the Fresnel Lens boosted the power output of the solar panel more than the other solar concentrators. The results do look promising but there are many factors that played into the average. Light conditions, solar panel orientation as well as lens distance/orientation played a significant role in how well the Fresnel lens, as well as the other solar concentrators, worked. For instance, in cloudy conditions, the Fresnel had no effect or even slightly negative effects. With that said, over all, especially in sunny conditions, the Fresnel lens was an effective, simple, compact and relatively inexpensive means of boosting the solar power generated by the solar panel.
PS: Connie and Kim think this doesn't sound like a 12 year old's conclusion :P
