This abstract describes a simple, low-cost device to improve power yields provided by fixed solar panel installations without the need to precisely position optical elements above the panel or add solar tracking and array positioning systems. The device utilizes one or more layers of optically refractive and/or diffractive materials imbued with specific contours and/or optical characteristics. The device is bonded directly to the solar array's sun-facing surface either as the array is manufactured, or retro-fitted to the array after installation. The device and bond interfaces may be comprised of any suitable optically high-transmittance material with refractive indices sufficiently higher than that of air. Additional gains in solar array power yields are made possible by the use of transparent, variable-contoured overlays or fluid-filled polymeric film overlays with modifiable optical characteristics which adapt to sun angle.
