FRP solar panel mounting brackets

FRP solar panel mounting brackets

Product Description

In the realm of PV installations, the use of Fiber Reinforced Polymer (FRP) profiles for mounting brackets offers several advantages. FRP is a composite material made of a polymer matrix reinforced with fibers, providing exceptional strength-to-weight ratio, corrosion resistance, and durability. When compared to traditional metal brackets, FRP mounting brackets exhibit superior resistance to environmental factors such as moisture, UV radiation, and chemical exposure. Furthermore, FRP profiles are non-conductive, reducing electrical losses and the risk of electrical hazards.

main components of an FRP solar panel photovoltaic mounting bracket

The main components of an FRP solar panel photovoltaic mounting bracket include various parts with specific functions. Here is a detailed description of these components:

  1. Main Beam: The main beam is the core component of the PV mounting bracket, responsible for supporting and securing the weight and load of the solar panels. It is typically a straight-shaped FRP profile, available in various shapes such as U-shaped, C-shaped, I-shaped, T-shaped, L-shaped, Z-shaped, or H-shaped.

  2. Bracing Bars: Bracing bars are used to reinforce and stabilize the main beam, preventing excessive deformation under wind load and other external forces. These bars are usually L-shaped or Z-shaped FRP profiles installed between the main beam and the ground, forming a support structure.

  3. Node Connectors: Node connectors are used to connect the main beam and bracing bars, ensuring overall stability and rigidity of the bracket. These connectors are typically made of metal or high-strength plastic and are used to fix and connect the ends or intersections of the FRP profiles.

  4. Base Supports: Base supports are used to support the entire PV mounting bracket system, securely fixing it to the ground or supporting structure. These supports are often made of metal and provide adjustable height and tilt angles to accommodate different installation sites and terrain conditions.

  5. Adjustment Components: For brackets with adjustable angles, adjustment components are used to change the tilt angle of the solar panels, maximizing solar radiation capture. These components may include adjustment rods, joint connectors, and locking devices, providing convenient angle adjustment functionality.

different forms of solar panel mounting brackets

  1. Fixed Mounting: Fixed mounting brackets are stationary structures that hold solar panels in a fixed position. The tilt angle is typically set at a fixed angle optimized for the geographical location. Fixed brackets are commonly used in installations where the sunlight exposure remains consistent throughout the day. They are simple in design and provide a stable and cost-effective solution for PV systems.

  2. Adjustable Fixed Mounting: Adjustable fixed mounting brackets, also known as tilt-adjustable brackets, allow for manual adjustment of the tilt angle of the solar panels. This flexibility enables optimization of the tilt angle based on seasonal variations or specific sunlight conditions. Adjustable fixed brackets offer the advantage of adapting to changing sun angles, maximizing energy production throughout the year.

  3. Automatic Tracking Mounting: Automatic tracking mounting brackets, also referred to as solar trackers, are designed to follow the sun’s movement throughout the day. These brackets use motorized systems to adjust the orientation and tilt angle of the solar panels, ensuring they constantly face the sun for maximum energy output. Solar trackers can significantly increase the energy generation of PV systems compared to fixed or adjustable fixed brackets, especially in regions with high solar exposure.

Each form of mounting bracket has its advantages and considerations, depending on factors such as the site location, available space, cost, and energy production requirements. The choice of mounting bracket form should be based on a thorough assessment of these factors to optimize the performance and efficiency of the solar panel system.

Fire Protection Requirements for Composite Material Brackets

During the operation of photovoltaic (PV) power systems, the presence of electric arcs poses a fire hazard. Therefore, it is required that polymer-based composite material brackets exhibit a certain level of flame retardancy. This standard selects two criteria, namely combustion performance and hot wire ignition test, to ensure the flame retardant properties of composite materials.

The combustion performance should meet the HB level requirements stipulated in GB/T2408-2008 “Determination of Burning Behavior of Plastics in Horizontal and Vertical Position”.

The hot wire ignition test should comply with the provisions of GB/T5169.11-2017 “Fire Hazard Testing for Electric and Electronic Products – Part 11: Ignition Test for Materials – Hot Wire Ignition Test (HWI) of Finished Products”. The test temperature is set at 750°C.

Based on actual test results, composite material brackets that meet both the combustion performance and hot wire ignition test criteria exhibit excellent flame retardancy. They meet the fire protection requirements for PV system applications and help to reduce the rapid spread of fires.
