Classification of photovoltaic brackets

1. Classification by material:

Hot-dip galvanized bracket: The surface is hot-dip galvanized to improve corrosion resistance. The bracket is usually made of steel or aluminum, with high strength and good stability, and is suitable for photovoltaic systems under various environmental conditions. The thickness of traditional hot-dip galvanized brackets is generally greater than 2mm, and for windy areas, the thickness can reach 2.5mm.
Galvanized aluminum-magnesium bracket: alloy metal plates are used, and the main components are zinc, aluminum, magnesium, etc. Due to the addition of alloy elements, the product has the characteristics of self-healing of cuts, and the metal surface is also chlorine-resistant, alkali-resistant, wear-resistant and corrosion-resistant, which can better cope with the harsh environment of deserts, tidal flats, saline-alkali land and other regions.
Weathering steel bracket: It is made of weathering steel through research and development and production. It has the mechanical properties of high-quality steel, and its atmospheric corrosion resistance is 2 to 8 times that of carbon steel. The longer the service time, the more outstanding the corrosion resistance. In addition, weathering steel brackets not only eliminate the galvanizing coating link, shorten the construction period and reduce costs, but also avoid the environmental pollution of hot-dip galvanizing processing.

2. Classification by structure type:

Single column bracket (L-shaped bracket): The photovoltaic module is fixed by a column perpendicular to the ground. It is suitable for smaller photovoltaic power station systems. It has a simple structure and is easy to install.
Double column bracket (T-shaped bracket): It consists of two columns perpendicular to the ground and a crossbar. The structure is more stable and can withstand greater wind force and weight. It is suitable for larger photovoltaic power station systems.
Frame bracket: A frame structure composed of multiple support rods and crossbars can be flexibly adjusted according to the size and number of photovoltaic modules. It is suitable for photovoltaic power station systems of various sizes.
3. Classification by installation method:

Fixed bracket: A bracket that cannot adjust the angle and direction. It has low cost and simple operation, but the energy output efficiency is relatively low. Fixed brackets can be divided into optimal tilt angle fixed brackets, inclined roof fixed brackets, tilt angle adjustable fixed brackets, etc.
Tracking brackets: It can automatically rotate according to the direction of sunlight, so as to always keep the photovoltaic module at the optimal angle of sunlight, which can greatly increase the power generation of photovoltaic modules. Tracking brackets can be divided into single-axis tracking brackets and dual-axis tracking brackets.

4. Classification by application location:

Ground bracket: usually used for photovoltaic projects in power stations or large industrial sites, easy to install and also has high stability.
Roof bracket: commonly used in residential or commercial buildings, simple structure, no need for additional ground space. Roof brackets can be divided into flat roof brackets and sloped roof brackets.
BIPV system (building integrated photovoltaic system): has both solar power generation and architectural decoration functions, and can be directly integrated into the building facade and roof.
Floating bracket: can float on the water surface, usually used in reservoirs, ponds and other areas with large water areas.
When choosing a photovoltaic bracket, it is necessary to comprehensively consider the specific needs of the photovoltaic project, site conditions, environmental factors, and cost-effectiveness, and choose the most suitable photovoltaic bracket type.
