Solar panels are designed to absorb sunlight and convert it into electricity, but they do reflect a small amount of light back into the atmosphere. Reflection is the enemy of efficiency. Factors affecting reflection include the angle of the sun, the type and color of the solar panel, the amount of sunlight hitting the surface. . Sunlight is the power source for photovoltaic (PV) systems, and how a solar panel interacts with that light determines its effectiveness. A common question arises from observing the dark, glass surface of an installed panel: does it reflect the sun's energy? While the primary purpose of a solar. . Most solar panels have an anti-reflective glass front surface that only reflects about 2 percent of incoming light. This means that the majority of the light is absorbed by the solar panel, allowing it to generate electricity.
