<p>Embodiments of the present invention relate to a method and apparatus for illuminating the surface of a solar cell using indirect sunrays. This forms a basis for solar panels that may be installed in places other than southerly oriented rooftops or open fields for direct exposure to sun. Sunrays are concentrated by a spherical lens on to the surface of optical fiber located within light guide. The concentrated light travels through optical fibers to the surface of solar cells located in a confined space, where the sun does not shine. The emerging sunlight from the end of the optical fiber is expanded through a series of mirrors, which eventually is reflected onto the surface of the solar cell, installed a fixed distance from the focal point of one of the mirrors.</p> |
