Description
Technical Field
The invention relates to the technical field of photovoltaic systems, in particular to an arc-shaped roof photovoltaic installation system.
Background
In recent years, the worldwide energy crisis and the energy consumption of China are increasing day by day, and the new solar photovoltaic energy is developed rapidly and rapidly; with the promise of our country for the dual-carbon target, more and more distributed photovoltaic projects are developing vigorously towards the direction of building, expanding and reconstructing roofs of factory buildings.
As time goes on, various defects can exist when the photovoltaic panel is used for building a newly-built factory building, a special-shaped structure roof of an old building and a roof of an arc building, and firstly, the solar bracket can not adjust the angle of the arc roof, so that wind resistance is not facilitated, and the appearance effect can not be achieved; secondly, the construction speed is slow, the construction period is long, and the cost is difficult to control.
When a solar photovoltaic panel construction system is additionally installed, a component support and a support keel of the photovoltaic panel system are important supporting structures for installing, bearing loads and fixing a photovoltaic module, the support and the keel are made of aluminum alloy, carbon steel and stainless steel, and the solar photovoltaic support has important influence on safe and efficient operation and project cost control of the photovoltaic system.
Meanwhile, when the photovoltaic system is struck by lightning, if a reliable lightning protection system is not provided, the generation power of the photovoltaic module is reduced or the inverter fails, the total generated energy is reduced, the economic benefit is reduced, and the later-stage equipment maintenance cost and the total project investment are increased, so that the rationality of lightning protection grounding in the photovoltaic system must be paid attention to.
As is well known, in the process of installing a photovoltaic system, an arc structure must be provided with anti-falling measures (such as a horizontal lifeline) on the surface of an arc roof due to the lack of reliable and safe protection rigid conditions, and conventional lifeline products are standard components, so that differences exist in installation of partial roofs, and a unique anti-falling system for the roofs is required.
From theoretical reality, when the sunlight incident angle is perpendicular to the photovoltaic module, the photovoltaic module is most favorable for power generation, and the conversion efficiency is highest. In the existing BAPV technology, a press block is mostly adopted to fix a photovoltaic module at a designated position, the assembly mode requires that the photovoltaic module is required to be provided with a frame and a support is arranged in a full-length mode, the arranged support needs an angle and has certain limitation, and for the optimal incident angle of an arc-shaped roof, the planar support cannot adjust the angle, so that the power generation efficiency of a photovoltaic panel is limited, and the requirement cannot be met; in addition, it is not economical to add keels repeatedly. Although the arc effect can be achieved by using the film type photovoltaic module, the cost is much higher.
The existing broad application of the roof distributed photovoltaic power station is that the conventional roof is mostly in a regular plane geometric shape, and the photovoltaic panel assembly is relatively easy to construct. However, for arc building roofs such as coal shed roofs of power plants and curved roof projects of public buildings, due to the fact that various angles exist, when a plane photovoltaic panel is installed, radian changes cannot be adapted, standardized installation and construction are difficult to achieve, and construction difficulty is high. The prior art is mostly cadmium telluride thin film power generation, the cost is greatly improved, and the common BAPV system component needs to be provided with an aluminum alloy frame, the load is heavier, the dust is easily accumulated to form hot spots, the fireproof grade of the material is low, the installation speed is slow, and the photovoltaic panel is difficult to be fully unfolded and arranged.
