Subterranean Solar, or SubSolar, is a unique and innovative system of utilizing "subterranean solar panels" to gather solar power. No unsightly above ground solar panels need to be used anymore. How Does It Work? A compact optical device is installed upon a rooftop or other sunlight-catching environment. This optical device captures and magnifies the sun`s rays and transfers the sunlight from its linear or cylindrical lenses though fiber-optic lines leading down into an underground storage of solar panel modules.
