What type of energy conversion occurs in solar panels?

• A. Electric to thermal
• B. Chemical to thermal
• C. Radiant to electric
• D. Mechanical to electric

Answer: (C)

Solar panels convert radiant energy from sunlight into electrical energy through the photovoltaic effect. When sunlight strikes the solar cells in the panels, photons from the light can knock electrons loose from atoms within the semiconductor material of the solar cells. This process generates a flow of electricity as the dislodged electrons move through the material, creating an electric current. This conversion is integral to the functionality of solar panels, allowing them to efficiently harness solar energy and transform it into a usable form of electricity for homes, businesses, and other applications. The primary focus is on the transformation of radiant energy, which comes from the sun, into electrical energy that can be utilized for various power needs. The other energy conversion types listed in the options do not accurately describe the process that takes place in solar panels.
