Description
Technical field
The utility model is related to a kind of photovoltaic module, particularly a kind of lightweight photovoltaic module.
Background technology
Photovoltaic module, is the core in solar power system, is also most important portion in solar power system
Point, its effect is to convert solar energy into electrical energy, or is sent in battery and stores, or promotion loaded work piece.Generally, photovoltaic
Component typically uses toughened glass panel and frame made of aluminum profiles, and in order to ensure overall construction intensity, commonly used tempering
Glass panel and frame made of aluminum profiles are more abundant, and photovoltaic module overall weight is larger, and it is certain that this installation and conveyer belt come
Burden, therefore, need badly develop a kind of photovoltaic module of more lightweight on the market.The thickness of reduction safety glass simply, no
The problem of simply failing to ensure enough intensity, and also easily toughened glass self-explosion occur during specific Assembling Production；And use it
When its light plastic is as panel, be difficult again solve plastics easily by translucency after raindrop erosion, aging it is poor the problem of.
Utility model content
The purpose of this utility model is that there is provided a kind of lightweight photovoltaic module.It can meet rigidity and mechanical load
While Capability Requirement, mitigate component overall weight, be easy to the transport and installation of component.
The technical solution of the utility model：Housing on the outside of lightweight photovoltaic module, including photovoltaic panel and photovoltaic panel, its feature
It is：The photovoltaic panel include be arranged in order from bottom to up ETFE backboards, bottom EVA film, photovoltaic cell, top EVA film,
ETFE panels and safety glass protective layer；PVB glued membranes are provided between the ETFE panels and safety glass protective layer；The housing
Including BMC skeletons and the aluminium alloy shell being coated on the outside of BMC skeletons.
In foregoing lightweight photovoltaic module, the ETFE plate thicknesses are 0.8mm~1.2mm, safety glass protection thickness
Spend for 2.0mm~2.5mm, ETFE back plate thickness is 0.5mm~0.8mm.
In foregoing lightweight photovoltaic module, the BMC skeletons are uniformly placed with multiple in the side close to aluminium alloy shell
Raised fin.
In foregoing lightweight photovoltaic module, the BMC skeletons are provided with EVA sealants close to the side of photovoltaic panel.
Compared with prior art, the utility model introduces ETFE backboards and ETFE panels in the structure of photovoltaic panel, can
To improve overall construction intensity, so as to reduce the thickness of safety glass, mitigate overall weight.And due to ETFE materials tool
There is higher guide-lighting performance, the utility model is compared to the photovoltaic module using stack pile glass, and power output also may be used during generating
To obtain certain lifting.Other ETFE heat resistances are good, and there is the protection of safety glass protective layer in outside, not perishable old
Change, it is permanent durable, and safety glass protective layer and ETFE panels can be hot pressed into one using PVB glued membranes in assembling and have
Compared with being reassembled after the entirety of high structural strength, the problem of less safety glass of thickness is easily revealed can be solved.On the other hand,
The utility model also using can the frame structure that is combined with BMC skeletons of aluminium alloy shell, relative to traditional frame made of aluminum profiles, up to
In the case of same structural strength, safety glass thickness can be decreased to 2.5mm, and the aluminium alloy of frame can be decreased to
25mm, can mitigate more than 30% weight, and the good insulation preformance of BMC skeletons relatively, not only corrosion-resistant, anti-aging, scattered
Heat energy power is also stronger.
