Description
MODULAR PHOTOVOLTAIC ELEMENT FOR BUILDING ROOFS.
The present invention relates to a modular photovoltaic element for building roofs.
Modular elements of clay material are known for forming building roofs. They are commonly known as plain tiles or single-lap tiles depending on their shape, the present description using exclusively the term "tile", even though the invention also relates to modular elements different from plain tiles.
For some time, photovoltaic modules have been proposed as a io replacement for traditional clay tiles, they being hence known as photovoltaic tiles. They have generally lost their traditional shape, which is often incompatible with the connections required between one tile and the next, and incompatible with the need for a surface transparent to the sun's rays and the ability to define with the remaining part of the tile a chamber is for housing the photovoltaic cells. Consequently the roofs made with these photovoltaic tiles have lost the appearance of classical roofs and integrate unsatisfactorily within an environmental context.
An object of the invention is to eliminate these drawbacks by providing photovoltaic tiles which are totally similar externally to classical 20 tiles but which on installation are able to establish the necessary connections with the adjacent tiles and/or with conductors for transferring the electrical energy generated thereby to the outside.
This and other objects which will be apparent from the ensuing description are attained, according to the invention, by a modular 25 photovoltaic element for building roofs as described in claim 1.

The upstream end of the part 4 comprises a cavity 32 housing a watertight female connector 34 for connection to the upstream tile pertaining to the same row.

The cover element 6 is made of transparent material and is of frusto-conical shape matching the frusto-conical shape of the edge of the part 4, to give the tile the shape of a traditional tile. For mechanical strength reasons the cover element 6 presents a plurality of lower 25 stiffening ribs and also a plurality of teeth 26 for engaging in the seats of the part 4, to fix the cover element 6 to the part 4.

6 PCT/EP2007/057822 In particular, laying the bottom tile of each row also determines the connection to the cables for transporting the generated direct current electrical energy into the building for its use. More particularly, the first tiles of each row have at their end the exit for two cables, of positive and negative polarity respectively, which carry the direct current electrical energy into the building. Of the two cables which emerge from each first tile, one is connected to the first tile of the adjacent row, to form in this manner a series connection between the various rows. The two terminals of the series formed in this manner are connected to an inverter positioned io inside the building, to convert the direct current into alternating current.
The various cables are also connected to the overall electronic control unit for transmitting the data originating from the integrated circuit 40 of each tile.
In laying the next tile, achieved by firstly laying the base 2 and is then engaging its lower part 4 by coupling, this lower part surmounts a portion of the part 4 of the previously laid tile, hence causing the male connector 30 of this subsequently laid part 4 to connect into the female connector 34 of the previously laid part 4, and determining the electrical connection between the two adjacent tiles. During this step the closure of 20 the seat 32 can be advantageously sealed by interposing a continuous gasket 50 between the two surmounted portions of the two adjacent parts 4.
After the entire row has been completed, the operator lays the adjacent corner, being careful to couple the appendices 12 of two adjacent 25 bases and then stabilize the bases in their correct position by engaging a single fixing screw.
