Active Solar Design refers to the use of mechanical systems to capture and convert solar energy into usable forms, such as electricity or heat. This approach typically involves solar panels, which collect sunlight and convert it into electricity, and solar thermal systems, which use sunlight to heat water or air for residential or commercial use. These systems often include components like pumps, fans, and controllers to distribute the collected energy efficiently. By integrating solar technology into building designs, Active Solar Design can significantly reduce reliance on fossil fuels and lower energy costs, contributing to a more sustainable environment.
