Multilayer coatings are widely used to various optical parts, for example, multimode optical fibers, beam splitters, antireflection coatings. For another applications, multicoated thin films on the solar panel have capabilities to control the solar energy by means of the spectrum transmittance and reflectance control. In this paper, we discuss the specifications and the functions of solar panel coatings. In the design of optical multilayer coatings, refractive index and thickness of each layer must be determined in accordance with the specifications on a spectral reflectance. The solar spectrum, the culmination altitude and conditions of the production process for coatings must be considered. To solve the problem, our developed design system is used for optimum design. Some optimum design results for restricted design specifications are shown.
