Characteristics of Different PV Bracket Design Schemes

2025-11-24

A PV (photovoltaic) bracket system refers to a supporting structure that fixes PV modules in a specific orientation, arrangement, and spacing to achieve the maximum power output of the entire photovoltaic power generation system, considering the geographical, climatic, and solar resource conditions of the construction site. It is usually made of steel structure, aluminum alloy structure, or a hybrid of both.

1. Sloped Roof PV System

Characteristics of Sloped Roof PV System Brackets:

Suitable for tiled roofs with adjustable heights for different thicknesses and flexible accessories;
Multi-hole design for connecting plates and other accessories enables flexible and effective adjustment of bracket positions;
Does not damage the roof's inherent waterproof system.

2. Flat Roof PV System

Common flat roof types include: concrete flat roofs, color steel plate flat roofs, steel structure flat roofs, spherical node roofs, etc.

Characteristics of Flat Roof PV System Brackets:

Large-scale and neat layout;
Multiple stable and reliable foundation connection methods.

3. Large-Scale Ground PV System

Common large-scale ground PV systems generally adopt concrete strip (block) foundation (for special foundation conditions, consult professional geomechanical designers).

Characteristics of Large-Scale Ground PV System Brackets:

Quick installation to match the construction progress of large-scale ground PV power plants;
Flexible adjustment forms to meet the complex and variable requirements of construction sites;
Streamlined number of accessories for easy identification and installation by on-site workers.

4. Column-Mounted PV Bracket

Characteristics of Column-Mounted PV Brackets:

Maintenance-free, high reliability, and long service life;
Fixed system without the need for movement;
Wind resistance ≥ 200 km/h, suitable for areas with high wind speeds.
