The photovoltaic tile can adopt a full-length structure and a non-full-length structure.
When the photovoltaic tile adopts the through-length structure, the photovoltaic tile only contains one photovoltaic tile from the ridge to the eave direction of the photovoltaic roof, namely, the photovoltaic tile only needs to be paved side by side along the ridge direction to complete the assembly of the photovoltaic roof.
When the photovoltaic tile adopts the non-through long structure, the photovoltaic roof is assembled in the process of assembling the photovoltaic roof, and the photovoltaic roof is assembled along the ridge direction and from the ridge to the eave.
Further, at least one photovoltaic tile is connected with the tile substrate of the photovoltaic tile of the above embodiment in a locking manner, the tile substrate of the photovoltaic tile extends to an eave from the ridge of the photovoltaic roof, and a pedal for treading is arranged on the tile substrate of the photovoltaic tile. Effect a realizable mode, the tile base plate of photovoltaic tile and photovoltaic tile all adopts logical long structure, and this photovoltaic tile's tile base plate can regard as fortune dimension passageway to use, and the staff can step on the footboard that sets up on this photovoltaic tile's tile base plate, moves between eaves and ridge to install or maintain.
In order to determine the effect of the heat dissipation channel on the heat dissipation capability of the photovoltaic tile, simulation is performed through simulation software to compare the temperature of the existing photovoltaic tile with the temperature of the photovoltaic tile with the heat dissipation channel structure in the embodiment.
The conditions simulated were: the ambient temperature is 20 ℃, the included angle between the photovoltaic tile and the horizontal plane is 5 degrees, the place is Xian (34 degrees in northern latitude and 108 degrees in east longitude), and the solar radiation of 8 months, 1 day, afternoon and 2 o' clock is taken for obtaining the maximum illumination.
Through simulation, the temperature of the upper surface of the photovoltaic tile is 70.50 ℃, the temperature of the cell is 71.33 ℃, and the temperature of the tile substrate 8 of the photovoltaic tile is 70.29 ℃;
the upper surface temperature of the existing photovoltaic tile is 82.94 ℃, the temperature of a cell is 86.69 ℃, and the temperature of a tile substrate 8 of the photovoltaic tile is 87.80 ℃;
the simulation result shows that the temperature of the photovoltaic tile is lower than that of the existing photovoltaic tile by more than 10 ℃. The reduction of photovoltaic tile temperature can guarantee the stability and the reliability of battery piece work on the one hand, and on the other hand can also reduce the photovoltaic tile back and set up requirements such as insulating layer, reduces use cost, and under the condition that adopts the same thickness insulating layer, the indoor temperature of the photovoltaic tile that adopts this embodiment to provide is less than the indoor temperature of adopting current photovoltaic tile.
