The module that includes solar wafer is also known as photovoltaic module, and when photovoltaic module set up on the roof, there are two kinds of mounting means usually: extending a connecting piece on the original roof to be manufactured above the existing roof; or directly replace the original roof structural member. When photovoltaic module installs in existing roof top, in order to take away the heat that photovoltaic module during operation produced that can be fine, need keep equipment such as ventilation or installation air-blower, but with high costs, and cause thermal waste. When the photovoltaic module directly replaces original roof structure, the heat that the photovoltaic module produced is difficult to eliminate, leads to indoor high temperature, influences the travelling comfort.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a photovoltaic roof, which not only can fully utilize the heat generated by the photovoltaic module, but also can ensure a better heat dissipation effect.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a photovoltaic roof, sets up in the building top, includes first panel and second panel, the second panel is fixed at the building top, first panel sets up the top at the second panel, first panel includes solar wafer, first panel and second panel end are connected and constitute the cavity, first vent and second vent have been seted up on the cavity, first vent height is less than second vent height.
Further, in the above technical solution, the first ventilation opening and the second ventilation opening are both provided with a valve and a controller for controlling ventilation volume, and the valve is electrically connected with an output end of the controller.
Furthermore, a temperature sensor is arranged in the cavity, and a signal output end of the temperature sensor is connected with a signal input end of the controller.
Further, in the above technical solution, the second panel is a metal plate.
Further, in the above technical solution, the second panel is horizontally disposed.
Further, in the above technical solution, the first panel and the second panel are disposed in parallel.
Further, in the above technical solution, a shielding plate is disposed at the first ventilation opening and/or the second ventilation opening.
The utility model has the beneficial effects that: when the weather is hot, hot air in the chamber can be discharged from the vent at the higher part by utilizing the height difference between the first vent and the second vent, and cooler air enters from the vent at the lower part, so that the effect of taking away redundant heat in the chamber is achieved; when the weather is cold, reduce or close the air volume of vent, the heat that photovoltaic module produced on the first panel can rise the temperature of cavity to form the heat preservation roofing, avoided insulation material's use.

Fig. 1 is a schematic structural diagram of a photovoltaic roof provided by the present invention.
Detailed Description
The utility model will now be described in further detail, including the preferred embodiments, with reference to the accompanying drawings and by way of illustration of some alternative embodiments of the utility model. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
As shown in fig. 1, a photovoltaic roof, which is arranged at the top end of a building, comprises a first panel 1 and a second panel 2, wherein the first panel 1 is arranged above the second panel 2, and the second panel 2 is fixed at the top of the building; the first panel 1 includes a solar cell sheet 3 for generating electricity, and it is understood that the solar cell sheet 3 is disposed toward the side having sunlight. The end portions of the first panel 1 and the second panel 2 are connected to form a cavity 4, the cavity 4 is provided with a first ventilation opening 5 and a second ventilation opening 6, the first ventilation opening 5 and the second ventilation opening 6 have a height difference, the number of the first ventilation opening 5 and the number of the second ventilation opening 6 can be set according to actual needs, and specifically, in the embodiment, the horizontal height of the first ventilation opening 5 is lower than that of the second ventilation opening 6.
On the premise of ensuring the height difference of the two air vents, the first panel 1 needs to be obliquely arranged, and the second panel 2 can be horizontally arranged or obliquely arranged; in the embodiment, the first panel 1 and the second panel 2 are arranged in parallel and form an inverted V-shaped structure; preferably, in the present embodiment, the first ventilation opening 5 is provided at an eave, and the second ventilation opening 6 is provided at a ridge.
In practical application, first panel 1 can be the photovoltaic product of integration, also can be formed by the concatenation of multi-disc photovoltaic tile, in order to strengthen the firm degree of first panel 1, can also set up a plurality of connecting pieces 8 in cavity 4, the both ends of connecting piece 8 are connected in first panel 1 and second panel 2 respectively.
Further, the substrate of the first panel 1 and the second panel 2 can both be metal plates, which not only can ensure heat conduction, but also has the advantages of light weight, easy installation and the like. To avoid rain water and impurities entering the chamber, a baffle 7 may be provided at the vent.
