Photovoltaic roof tiles are known to replace conventional roof tiles in a single-lap arrangement. To prevent rain water from passing between adjacent tiles and leaking into the building below, such photovoltaic roof tiles are provided with interlocking edges; however, these can be expensive to manufacture and time-consuming to install. A more cost-effective option of tiling would be to use a double-lap tile arrangement. Because plain tiles have no interlocking edges, water can leak through the joins between tiles. This requires a third tile to be placed below the join to catch any water passing through. However, with double-lap tiles, a significant part of each tile remains covered after installation, such that a relatively small surface area is in view of the sun. This not an efficient use of expensive photovoltaic materials. The present invention provides a photovoltaic roof tile 302 for use with double-lap tiles 301, the photovoltaic roof tile 302 having a tile width equal to an integral multiple of the double-lap tile width. In this way, such photovoltaic roof tiles 302 may be arranged with conventional double-lap roof tiles 301 to increase the proportion thereof available to sunlight 305, 307, without risking ingress of water.
