NOVELTY - The tile (10) has an outer surface fitted with solar cells that are equipped with conductors and connectors. A substrate (4) is made of non-combustible plastic or synthetic resin. A flexible solar cell layer (2) contains the solar cells applied to an outer surface of the substrate. The solar cell layer is sealed in a waterproof manner by a transparent protective layer (1) that tightly conforms to a shape of the outer surface of the substrate, where the protective layer is a clear, weather, heat and frost resistant film laminated to the substrate.    USE - Solar roof tile for generating electric power, and for being installed into a roof cladding for solar roofing, facade and building paneling.    ADVANTAGE - The solar roof tile can be installed into the roof cladding consisting of roof tiles of any shape, and avoids disrupting the form and unity of the roof surfaces so as to fit the solar roof tile in a better manner. The solar roof tile can be fashioned in any form and color, such that the solar roof tile can be used on listed buildings. The solar roof tile avoids a need to perform any conversions to the roof structure or build in separate units. The solar cell roof tile is light in weight, and can fits the battery in order to facilitate the utilization of the power accumulated during sunny periods at night or on overcast days. The design of the solar cell roof tile can indicates any defects of the solar cell roof tile, during occurrence of an error by illuminating the built-in error indicator light, such that any malfunctioning solar cell roof tiles can be easily located and replaced.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a process for manufacturing a solar cell roof tile.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an electric power generating solar cell roof tile in a battery.
