Solar Skylight Allows for Light and Power
A window that allows light in, keeps heat out and turns the sun's rays into useful energy - Pythagoras Solar, a newcomer to the solar energy field has designed a photovoltaic glass window that will replace the traditional skylight found on the facades and roofs of commercial buildings. The window is assembled by putting two panes of specially designed glass into a frame. Each pane of glass is made up of several rectangular tiles that contain a solar cell and a series of embedded mirrors. The sunlight is redirected toward the solar cell by the mirrors and electricity is created. A plastic prism installed on the outside of the unit manipulates the optics in order to provide the maximum electrical power. The energy is captured by the solar cell and heat is dissipated through the materials that make up the component window.
The design of the building and how much sun it is exposed to will determine the energy generating power of the Pythagoras skylight. As an example, a window or windows placed on the top of a building that is constantly exposed to direct sunlight will be able to collect and store more energy than a building shaded by trees.
