Instead, the solar panels, known as "collectors," transform solar energy into heat. Therefore, these panels don't need heat; they need photons (light. . At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect. The temperature increases due to the photovoltaic effect - the conversion of light into electricity - which is not 100% efficient and results in the generation of heat. Below, you can find resources and information on the. . Solar thermal energy – This method uses sunlight to produce heat, which is then used for various applications, such as heating water or generating steam to drive turbines for electricity production.
