Solar thermal systems are technologies that capture and utilize sunlight to generate heat. They typically consist of solar collectors, which absorb sunlight and convert it into thermal energy, and a heat transfer system that moves this energy to where it is needed, such as in water heating or space heating applications. These systems can be used in residential, commercial, and industrial settings. They are often more efficient than traditional heating methods and can significantly reduce energy costs. Common applications include heating water for swimming pools, domestic use, and even powering industrial processes.
