PHOTOVOLTAIC ROOF TILES

Resumen de: CN119403984A

Known photovoltaic roof tiles replace traditional roof tiles in a single lap arrangement. In order to prevent rainwater from passing between adjacent tiles and permeating into a building below, the photovoltaic roof tile is provided with interlocking edges; however, the manufacturing cost of these devices may be very high, and the installation is also time-consuming. One more economical choice of laying tiles is the use of a double lap tile arrangement. Because the planar tiles have no interlocking edges, water may leak through the joints between the tiles. This entails the placement of a third tile under the joint to intercept any passing water. However, when the double lap tiles are used, a substantial portion of each tile is still covered after installation, so that a relatively small surface area can be exposed to the sun. This is not effective utilization of expensive photovoltaic materials. The invention provides a photovoltaic roof tile 302 for use with a double lap tile 301, the tile width of the photovoltaic roof tile 302 being equal to an integer multiple of the width of the double lap tile. In this manner, such a photovoltaic roof tile 302 can be arranged with a conventional double lap roof tile 301 to increase the proportion it can be used to receive sunlight 305, 307 without the risk of water ingress.
