Solar Roof tops Panels are also known as Solar Thermal Panels, most of the solar panels are fixed on roof top for getting direct sunlight. It absorbs sunlight as a source of energy to generate electricity. Photovoltaic modules use light energy (Photons) from the sun to generate electricity through the Photovoltaic effects. A Photovoltaic junction box is attached to the back of the solar panel and its output interface. Externally, most of the photovoltaic modules use MC4 connector type to facilitate easy weatherproof connections to the rest of the system. Also, the USB power interface can be used. The solar panel also use metal frames consisting of racking components, brackets, reflector shapes, and troughs to better support.
