Can a magnifying glass actually boost the power output of a solar panel? Well, the answer is yes, but there's a catch. We'll also discuss a more practical solution – concentrating photovoltaic (CPV). . A magnifying glass, also known as a convex lens, works by converging light rays to a single focal point, intensifying the energy contained within those rays. That's enough heat to boil water, light stuff on fire, or even melt some metals. A magnifying glass acts as a simple but surprisingly. . Magnifying glasses are simple optical devices that use curved glass to concentrate sunlight onto a focal point.
