Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, and in particular to an installation structure of a lightweight photovoltaic component roof. Background Art

[0002] Photovoltaic modules, also known as solar panels, are the core and most important part of a solar power generation system. Their function is to convert solar energy into electrical energy, either by storing it in batteries or by driving loads.

[0003] In the prior art, the bearing capacity of the factory roofs of some enterprises does not meet the requirements of the newly added photovoltaic load. The factory roofs include color steel roofs, cast-in-place concrete roofs, and prefabricated lightweight concrete board roofs. These roofs cannot be installed with photovoltaic brackets and components in a conventional manner. Conventional components weigh about 11.06kg / square meter, the weight of color steel roof brackets is 3.6kg / square meter, and the weight of concrete roofs is about 50kg / square meter. The use of conventional components with corresponding bracket systems is suitable for roofs that meet the newly added loads. For roofs that do not meet the newly added corresponding system loads, or because the factory roof structure is old, or the roof cannot be effectively fixed and connected, the existing photovoltaic system cannot be installed. If the existing solution is used for installation, there are problems with safety and firmness, and it cannot effectively meet the operating life. Therefore, a lightweight photovoltaic component roof installation structure is needed to meet people's needs. Utility Model Content

[0006] The beneficial effects of the utility model are:

[0007] In the utility model, a new protective layer will be formed on the roof to prevent the waterproof layer from aging and also have a heat-insulating effect.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0013] Reference Figure 1-3 A mounting structure for a lightweight photovoltaic module roof comprises a lightweight photovoltaic module 100 and a roof 200, wherein an aluminum alloy support rail 101 is fixedly installed between the lightweight photovoltaic module 100 and the roof 200, an upper structural frame 102 is fixedly installed at the connection between the lightweight photovoltaic module 100 and the aluminum alloy support rail 101, and a lower structural adhesive 103 is fixedly installed at the connection between the aluminum alloy support rail 101 and the roof 200. A new protective layer will be formed on the roof to prevent the waterproof layer from aging and also has a heat insulation effect. This solution is installed on the roof as a full-coverage paving, which can form a BIPV photovoltaic building integration effect with the roof, and has the practical ability of BIPV photovoltaic building integration.

[0014] Working principle of this utility model:

[0015] The components and materials of the roof installation plan include lightweight photovoltaic modules, aluminum alloy connectors, aluminum alloy support rails, weather-resistant structural adhesive, expansion bolts or conventional fastening bolts; the installation is to bond the aluminum alloy connectors to the roof surface, install the aluminum alloy support rails on the connectors, or directly bond the aluminum alloy support rails to the roof surface, bond the lightweight photovoltaic modules to the aluminum alloy support rails, and seal the gaps between the modules with structural adhesive; if the roof condition is relatively flat and smooth, the plan of directly bonding the lightweight photovoltaic modules to the roof surface can also be adopted.

[0016] The weight of lightweight photovoltaic modules is about 3.25kg / ㎡, and the weight of conventional photovoltaic modules is about 11.06kg / ㎡, which is more than three times the weight difference. Therefore, it is the best choice to install and construct photovoltaic power stations on roofs with poor conditions or unsatisfactory loads.

[0017] The utility model is mainly aimed at roofs whose loads do not meet the requirements of newly added conventional photovoltaic loads, such as lightweight concrete board roofs, grid roofs, old color steel roofs, etc. The overall load of the utility model is relatively light, and most roofs can be installed. It is installed by bonding with weather-resistant structural adhesive, which is simple to install and has a solid structure. It protects the roof waterproof layer, reduces leakage problems caused by disrepair of the waterproof layer, enhances the thermal insulation performance of the roof, and perfectly reflects the BIPV building integration effect.

[0018] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
