Product Description

Parameters

· Less geographically restricted

· Short construction period

· It is safe and reliable, noise-free, low pollution, no fuel consumption and erection of transmission lines

Stationary PV mounts have a simple structure and no complex adjustable parts, which makes them relatively inexpensive to manufacture and install. Since no additional drive system is required to adjust the angle, the overall investment costs are reduced.The installation process is straightforward and simple, often requiring only a pre-calculated optimum inclination to be fixed to the ground or roof, reducing installation time and labor costs. At the same time, since there are no moving parts, routine maintenance work is mainly focused on the cleaning and inspection of photovoltaic modules, which is low and easy to maintain.The fixed design ensures the stability of the bracket in the face of various climatic conditions, such as strong winds, rain and snow, etc., to maintain the stability of the structure and reduce the risk of component damage caused by the movement of the bracket.

Design Considerations

When selecting a rooftop PV fixed racking system, several factors should be considered:

• Roof Type: Metal, concrete, or tile roofs require different mounting solutions；
• Load Capacity: Ensure the roof can support the additional weight；
• Wind and Snow Loads: Structural design must meet local standards；
• Tilt Angle: Optimized for geographic location to maximize energy output；
• Corrosion Resistance: Especially important for coastal or high-humidity areas；

Application Scenarios

PV fixed racking systems are ideal for:

• Industrial and commercial rooftop solar projects
• Residential solar installations
• Distributed energy systems
• Retrofitting existing buildings with solar capability

Single Axis Solar Tracker system
Flat single-shaft photovoltaic supporting bracket is suitable for low latitudes. It usually tracks the height angle of the sun to increase the vertical component of the solar rays on the battery panel to increase its generating capacity. It is divided into north-south axis tracking and east-west axis tracking. The east-west axis tracking has no obvious advantages over fixed inclined installation, and the tracking effect of north-south axis is better than that of east-west axis. The flat single-shaft photovoltaic supporting bracket has one shaft to automatically track the sun in the east-west direction every day with simpler structure, ingenious assembly and strong terrain adaptability. The rotating parts are made of stainless steel, which are maintenance-free and have a design life of more than 25 years.
