For material selection in photovoltaic carport support systems, it is recommended to follow the strategy of "environmental priority, structural safety, and cost-effectiveness." The following are specific material recommendations based on current industry standards and technical requirements:...
I. The Ultimate Challenge for High-Rise Roofs
Installing photovoltaic systems on high-rise buildings presents far more complex challenges than those encountered on ordinary villas or factory roofs:
Stringent Load Restrictions
Weight is critical: Roof structures in high-rise buildings are eng...
The rusting of brackets is typically not caused solely by "water splashing onto them," but rather by the combined effect of multiple factors:
1. Environmental Corrosion (Most Common Cause)
Roof-mounted brackets are more susceptible to environmental factors than ground-mounted ones.
Mois...
1. Core Attributes and Structural Characteristics
Aluminum Alloy Bracket
Primary Composition: Primarily composed of aluminum alloy grades such as 6063 and 6005, belonging to the Al-Mg-Si alloy series.
Density and Weight: Density approximately 2.70 g/cm³, weight per square meter approximat...
1. Structural Safety Risk
Railings and building structures lack sufficient load-bearing capacity. A standard-sized photovoltaic module with its mounting system can weigh 15–25 kilograms. When this weight is applied to railings, the resulting leverage effect multiplies the actual lo...
Balcony railing photovoltaic mounting systems fall under the "balcony/roof non-penetrating mounts" segment within the photovoltaic mounting market. Serving protective, decorative, and structural functions, they are critical components for residential distributed PV systems.
In recent years, ba...
In the construction of ground-mounted photovoltaic power plant, the choice of foundation type directly determines system safety, construction duration, and long-term operational and maintenance costs. The two mainstream solutions currently are Independent Base and Composite Base.

Verification Technical Specifications
Material Thickness: Steel plate ≥2 mm, hot-dip galvanized coating ≥60 µm (≥80 µm in coastal areas)
Load-bearing Capacity: Wind and snow load calculations shall be performed in accordance with the Photovoltaic Mounting Structure Design Stand...
1. Safety Risks
Manifestations: Structural instability, overturning, collapse, potentially leading to roof leaks or fires.
Causes: Low-cost solar mounting systems often use thin steel plates, insufficient galvanization, or omit corrosion protection entirely, resulting in inadequate wind and sn...
1. Ballast-type Bracket
Advantages
No drilling required: Eliminates the need to drill holes in the roof surface, preventing damage to the waterproofing layer. Ideal for roofs with high waterproofing requirements (e.g., color-coated steel tiles, tile roofs).
Quick installation: Completed...
1. Ballast-type Brackets
l By placing precast counterweights (concrete blocks, metal blocks, etc.) on the bracket base or bracket body, the entire bracket is pressed onto the roof surface using gravity, ensuring stability without any bolts or anchors.
l The weight, positio...
