Could reflection increase the yield of solar energy?
Increasing the yield through reflection could make that an even more affordable energy supply option. Most of the advances in solar power production come from increasing the efficiency of the photovoltaic cells; the goal being to increase the watts produced per panel.
Why do solar panels have reflective surfaces?
Reflective surfaces are strategically positioned in front of solar panels with the purpose of redirecting incident light towards the photovoltaic modules, hence enhancing the overall light absorption efficiency. The incident light is subsequently reflected towards the solar panels, so enabling the generation of supplementary electrical energy .
