The dual-axis photovoltaic support system has two rotating shafts moving at the same time, which can ensure that the solar panels are always perpendicular to the sunlight. Therefore, dual-axis tracking can improve the efficiency of solar power generation. When encountering a force 8 wind, it can be adjusted to a horizontal direction to increase wind resistance and ensure the safety of the system.

The residential sound barrier will be designed with different structures according to the actual situation of the location and installation site. All-metal, fully transparent, a combination of metal and transparent, and large arc shapes can be used. It can also be made into an aesthetically pleasing sound insulation barrier according to the color and punching shape.

Razor barbed wire fences are made of a variety of materials. According to the different raw materials, they can be divided into razor barbed wire, plastic-sprayed razor barbed wire, galvanized barbed wire, PVC barbed wire protection nets, etc. The structure has sharp and raised wire elbows, which are used as protective materials. They are relatively strong and durable barbed wire protection nets. This durable barbed wire, when paired with a fence net, has a better protective effect. Generally, barbed wire is combined with chain link fences and frame fence nets, with a layer of razor barbed wire on the top, so that the safety is greatly enhanced, and users no longer have to worry about the various losses caused by unsafe materials.

Transparent sound barriers can be divided into combined transparent sound barriers (including metal parts) and fully transparent sound barriers. Transparent sound barriers are generally used in residential areas, highways, overpasses, etc., with high lighting, light transmission, observability, and landscape. Common transparent materials: PC board, acrylic, tempered glass.

The inclined single-axis photovoltaic bracket is not much more efficient than the fixed-tilt installation because the vertical line of the flat single-axis tracking solar panel always has an angle with the sunlight. The angle is larger in high-latitude areas.
