A low profile integrated solar roofing tile connecting system for the formation of a solar roof. The system is aesthetically appealing because the tiles lay relatively flat with a very low profile without any bulges or ridges because all wires and connectors embedded in the tiles. This low profile optimizes the roof's ability to withstand wind loads as well as minimizes cracking or breaking of the tiles due to external load forces. The connectors produce uniform spaces between adjacent tiles as well as providing an easy way to extend or exchange tiles.
