Types of Photovoltaic Bracket

 

Rooftop fixed mounts

These are designed to attach solar panels directly to the roof of a structure. They can be installed in a flat position or at a fixed angle optimized for the geographic location.

Pole mounts

Solar panels are mounted on a pole typically driven into the ground. Pole mounts can be fixed or allow some degree of adjustability. They are ideal for open spaces without suitable rooftop areas.

Ground mount frames

These frames are installed on the ground and provide a structure for panels to be placed at the optimal angle for sunlight absorption. Ground mounts are adjustable in some cases and offer easy access for maintenance.

Flat roof tilt mounts

Designed specifically for flat roofs, these mounts allow solar panels to be tilted at an angle that maximizes sunlight exposure despite being on a low-slope or flat surface.

Top of pole (TPO) mounts

Similar to standard pole mounts, TPO mounts are designed to be installed on the roofs of industrial buildings with a parapet wall. They raise the panels above the roofline for better exposure.

Tracking systems

Also known as solar trackers, these mounts adjust the position of solar panels throughout the day to follow the sun's trajectory, significantly increasing the energy output of the system.

Integral track systems

These are integrated into the building's structure during construction, allowing the solar panels to move with the building's movement, such as in the case of skyscrapers or bridges.

Integrated rail systems

These use an aluminum rail system that provides a strong, reliable, and adjustable mounting solution for solar panels, making installation faster and easier.

Ballasted mounts

These mounts do not penetrate the roof or the ground. Instead, they use concrete blocks or other weights to secure the mounting system in place, which is particularly useful on leased land or when roof penetration is not allowed.

 

Application of Photovoltaic Bracket

 

 

Residential solar power

Homeowners use photovoltaic brackets to install solar panels on their rooftops. These brackets are designed to withstand local weather conditions and can be adjusted for optimal tilt angles to maximize energy capture from the sun.

Components of Photovoltaic Bracket

 

1. Structural framework: This is the main support structure made of metal (often aluminum or galvanized steel), designed to hold the weight of the solar panels and withstand environmental forces such as wind, rain, and snow.

 

2. Mounting rails: These are horizontal beams that run along the length of the solar array, providing a uniform platform for attaching the panels to the framework.

 

3. End clamps and mid clamps: These clamps secure the solar panels to the rails without causing damage to the panel frame or affecting its performance. End clamps are used at the ends of the panels, while mid clamps are used to secure panels at intermediate points.

 

4. Foundation components: For ground mounts, these include concrete footings, ground screws, or other anchoring systems that provide a stable base for the mounting structure.

 

5. Bearings and pivots: In tracking systems, bearings and pivots allow the solar panels to move smoothly as they track the sun's path across the sky.

 

6. Drive mechanism: This component, found in solar trackers, includes gears, motors, and controllers that drive the motion of the panels to follow the sun.

 

7. Electrical boxes and wiring conduits: These are used to house electrical connections and protect the wiring that runs between the solar panels and the rest of the electrical system.

 

8. Adjustment mechanisms: Some brackets have built-in mechanisms that allow manual or automatic adjustment of the tilt angle for seasonal changes or to account for differences in sunlight exposure.

 

9. Wind struts and snow guards: Additional structural elements may be included to prevent panels from being damaged by high winds or accumulated snow.

 

10. Ballast weights: For ballasted mounts that do not penetrate the roof, heavy weights are used to secure the system in place.

 

11. Roof attachments: These are the parts that connect the bracket framework to the roof or structure, such as flashing, bolts, and sealants that ensure weathertightness and structural integrity.

Galvanized Steel PV Photovoltaic Brackets

 

Material of Photovoltaic Bracket
 

 

Aluminum

Known for its lightweight and corrosion resistance, aluminum is widely used in the manufacture of photovoltaic brackets. It is suitable for both rooftop and ground-mounted systems due to its strength-to-weight ratio and resistance to weathering.

Galvanized steel

Hot-dip galvanized steel provides excellent protection against rust and corrosion, making it another popular choice for solar panel mounting structures. It is particularly useful in environments where the bracket might be exposed to moisture and chemicals.

Stainless steel

Stainless steel offers superior corrosion resistance compared to galvanized steel and is often chosen for its longevity and aesthetic finish. However, stainless steel is more expensive than aluminum and galvanized steel.

Fiberglass-reinforced plastic (FRP)

FRP brackets are favored in corrosive environments, such as coastal areas or industrial zones, where resistance to salt, chemicals, and UV radiation is crucial. They are also lighter than metal alternatives.

Wood

In some instances, especially when the aesthetic of the structure is important, wood may be used as a component in photovoltaic bracket systems. However, this is less common due to wood's susceptibility to rot and insect damage.

Composites and plastics

Certain brackets may incorporate composite materials or plastics for specific parts, such as connectors or non-structural components, leveraging their resistance to UV degradation and chemical resistance.

 

Process of Photovoltaic Bracket

The process of manufacturing photovoltaic brackets typically involves several stages to ensure the final product meets the required specifications for strength, durability, and weather resistance. Here is an overview of the key steps involved in the production process:

Material selection

Based on the design, the appropriate materials are selected. Common choices include aluminum, galvanized steel, stainless steel, or composites. Material properties are considered in relation to strength, weight, corrosion resistance, and cost.

 
 

Cutting and forming

The chosen material is cut into the necessary shapes and sizes using techniques such as sawing, shearing, laser cutting, or waterjet cutting. After cutting, the materials may be bent or formed into the required shapes through processes like press braking or bending machines.

 
 

Welding and assembling

Components are assembled using welding techniques such as MIG, TIG, or spot welding, depending on the material and design. Assembling may also involve bolting, riveting, or using other mechanical fasteners if welding is not appropriate.

 
 

Surface treatment

To improve corrosion resistance and extend the lifespan of the bracket, surface treatments are applied. These can include powder coating, electroplating, hot-dip galvanizing, or painting. The treatment provides a durable finish that protects against weathering and UV exposure.

 
 

Quality control

Throughout the manufacturing process, quality control checks are performed to ensure the brackets meet design specifications and performance criteria. Inspections may include dimensional measurements, visual inspections for defects, and testing for strength and durability.

 
 

Finishing touches

Additional components like clamps, adjustment mechanisms, and hardware are installed. Labeling with part numbers and instructions for installation may also be included at this stage.

 
 

Packaging and shipping

Once the brackets pass all quality control checks, they are carefully packaged to prevent damage during transit and shipped to the customer or distribution center.
