Flat Roof / Ground Mounting

Rows Mounting System: According to the installation method, photovoltaic brackets can be divided into fixed brackets and tracking brackets.

Fixed bracket: A fixed bracket is a bracket that cannot adjust its angle and direction. It is usually used in areas where the solar altitude angle is relatively stable, with low cost and simple operation, but relatively low energy production efficiency. According to the setting method of inclination angle, fixed brackets can be divided into: optimal inclination angle fixed bracket, inclined roof fixed bracket, and adjustable inclination angle fixed bracket.

(1) Optimal tilt angle fixed bracket: Select the optimal tilt angle during installation to allow the photovoltaic module to absorb the most sunlight. Generally speaking, this tilt angle is around the local latitude plus 10 to 36 degrees. Mainly suitable for flat roofs and floors.

(2) Fixed bracket for sloping roof: It is a photovoltaic system designed for installation on sloping roofs. If the inclination angle is the same or close to the roof, better appearance and ventilation effects can be achieved. Usually used on tile roofs and light steel roofs.

3) Adjustable fixed bracket with adjustable tilt angle: It can be adjusted according to the lighting conditions and energy requirements in different situations, and the tilt angle can be changed by manual operation or electric device. This type of bracket is usually used in situations where it needs to adapt to changing lighting conditions (such as seasonal changes) or meet different energy demands. This type is commonly used for flat roofs and floors.

Tracking bracket: A tracking bracket is a bracket that can adjust its angle and direction to track the sun’s movement throughout the day. This allows for maximum efficiency in energy production, as the panels are always facing the sun. However, tracking brackets are more expensive and require more maintenance than fixed brackets. There are two main types of tracking brackets: single-axis and dual-axis.

(1) Single-axis tracking bracket: This type of bracket only adjusts the angle of the solar panels along one axis, either east-west or north-south. It is less complex and cheaper compared to dual-axis tracking brackets but still offers improved energy production.

(2) Dual-axis tracking bracket: As the name suggests, this type of bracket can adjust the angle of the solar panels along both the east-west and north-south axes. This allows for even more precise tracking of the sun’s movement and results in higher energy production, but it is also more expensive and requires more maintenance.

In general, fixed brackets are suitable for areas with stable sunlight conditions, while tracking brackets are better suited for areas with changing lighting conditions. It is important to carefully consider factors such as cost, efficiency, and maintenance when choosing between fixed and tracking brackets for your photovoltaic system. Additionally, regular inspections and maintenance should be conducted to ensure optimal performance of either type of bracket. Overall, both fixed and tracking brackets offer effective solutions for installing photovoltaic systems on flat roofs and ground mounts, providing clean and renewable energy for a sustainable future.
