Skyler, a curious learner, embarks on a journey to understand solar panels. She discovers how sunlight, composed of photons, is converted into electricity through the photovoltaic effect in solar cells. These cells, made of semiconductor materials like silicon, generate electric current when photons energize electrons. This current is then converted from DC to AC by an inverter for use in homes and businesses. Skyler reflects on the potential of solar energy for a sustainable future.
