Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation, and in particular to a lightweight and flexible photovoltaic module installation structure. Background Technology

[0002] With the rapid development of the photovoltaic industry, photovoltaic modules are increasingly widely used in the building sector. Traditional photovoltaic module installation structures are mostly suitable for large-size, heavy photovoltaic panels, which presents problems such as heavy weight, complex installation, and high requirements for roof structure. On some older buildings, lightweight roofs, or buildings with special shapes, traditional installation structures not only increase the roof load but may also lead to high construction difficulty and cost due to complex installation processes. Traditional structures require drilling holes in the roof to fix the brackets, which not only damages the roof waterproofing layer and increases the risk of leakage but also involves scaffolding construction and the use of heavy hoisting equipment, with labor and material costs accounting for 30% to 40% of the total project investment. At the same time, the support structure of traditional photovoltaic modules is insufficient in terms of stability and adaptability, making it difficult to meet the installation requirements in different environments.

[0003] With the rise of new lightweight photovoltaic technologies and products such as flexible thin-film photovoltaics and perovskite photovoltaics, the contradictions in the structural adaptability of existing installation technologies have become increasingly prominent. Based on this, a lightweight flexible photovoltaic module installation structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight and flexible photovoltaic module installation structure to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides a lightweight flexible photovoltaic module installation structure, including a lightweight flexible photovoltaic module installed on a roof and multiple support feet. The bottom left end of the lightweight flexible photovoltaic module is fixed to the roof via the support feet, and the right end is connected to a second support base via the support feet. The bottom of the second support base is adhered to the roof. The middle part of the lightweight flexible photovoltaic module is connected to a first support base via the support feet. The first support base is adhered to the roof.

[0006] Preferably, the lightweight flexible photovoltaic module includes a lightweight photovoltaic panel, longitudinal support aluminum beams, and transverse support aluminum beams.

[0007] Preferably, the contact ends of the horizontal support aluminum beam and the vertical support aluminum beam are bonded together with structural adhesive, and the angle between the horizontal support aluminum beam and the vertical support aluminum beam is connected by corner brackets.

[0008] Preferably, the support foot is one or both of the following: a slotted 5° support foot or a non-slotted 5° support foot. The slotted 5° support foot has a left slot at the left end or a right slot at the right end of its inclined surface. The non-slotted 5° support foot has no slots at either end of its inclined surface.

[0009] Preferably, the bottom of the left and right ends of the lightweight flexible photovoltaic module is provided with a slotted 5° support foot, and the bottom of the middle part is provided with a non-slotted 5° support foot.

[0010] Preferably, the slotted 5° support foot located at the left end of the lightweight flexible photovoltaic module is bonded to the roof, and the left end of the lightweight flexible photovoltaic module is snapped into the left slot of the slotted 5° support foot.

[0011] The bottom of the slotted 5° support foot located at the right end of the lightweight flexible photovoltaic module is mechanically engaged with the second support base, and the right end of the lightweight flexible photovoltaic module is engaged in the right slot of the slotted 5° support foot.

[0012] The non-slotted 5° support foot located in the middle of the lightweight flexible photovoltaic module is bonded to the lightweight flexible photovoltaic module, and the non-slotted 5° support foot is mechanically engaged with the first support base.

[0013] Preferably, the bottom of the left, middle, and right ends of the lightweight flexible photovoltaic module is provided with non-slotted 5° support feet.
