PV bracket lifts up the 'tracking tide'

Industry insiders unanimously believe that photovoltaic brackets are evolving from traditional fixed brackets to tracking brackets, and in the future, the penetration rate of tracking brackets in the global photovoltaic industry will continue to increase.

Tracking brackets are becoming a new tool for reducing costs and increasing efficiency in photovoltaic power generation systems. As the "skeleton"

supporting photovoltaic modules, the technical level and performance of photovoltaic brackets areIt directly affects the power generation efficiency and investment returns of photovoltaic power stations, and plays an important role in power station

investment. In recent years, technological innovation in major links of the photovoltaic industry has been accelerating.

The conversion efficiency and product power of photovoltaic modules continue to improve. In order to maximize the value of photovoltaic modules,

photovoltaic brackets have evolved accordingly.Industry insiders agree that photovoltaic brackets are evolving from traditional fixed brackets to tracking brackets, and in the future, the penetration

rate of tracking brackets in the global photovoltaic industry will continue to increase.

Fortune Securities predicts that global tracking bracket shipments will reach 95 GW, 115 GW and 135 GW from 2024 to 2026 respectively; the domestic

market outlook is also positive.

The compound growth rate will maintain a high growth rate of more than 20% in the next five years.

Promote power generation

In the view of Ma Weiming, president of Trina Solar's global tracking bracket business unit, photovoltaic brackets are of great significance to the

high-quality development of photovoltaic power stations.

The role of the photovoltaic support system can be likened to the 'foundation and frame of a house'. Just as the foundation and frame determine

the stability and structural strength of the house, the photovoltaic support system supports and fixes the photovoltaic panels.

It enables stable operation at different angles and conditions, maximizing the absorption of sunlight and increasing power generation.”

At present, photovoltaic brackets are mainly divided into two categories: fixed brackets and tracking brackets. Fixed brackets generally use the

maximum inclination angle of solar radiation in a year as the installation inclination of photovoltaic modules.

The angle is not adjustable or needs to be adjusted manually seasonally. The tracking bracket can track the sun's position in real time and actively

adjust the direction of the photovoltaic module to maximize the use of solar radiation.

And increase power generation and achieve higher power generation revenue.

Ma Weiming explained: "The tracking bracket is mainly composed of three parts: the structural system, the drive system and the control system.

The drive system is the power source of the tracking bracket, which can move the photovoltaic modules

It can be placed at the best angle to track the sun. It is precisely because of this ability that the cost of electricity and investment return of the

photovoltaic power station over its entire life cycle can be calculated.

Tracking stents have more advantages.”

Weng Kailei, general manager of Yunnan Branch of PowerChina East China Institute of New Energy, said: “The biggest feature of the tracking

bracket is that it can track sunlight autonomously to better play the role of photovoltaic groups.

Especially in the case of relatively flat terrain and stronger ground reflection, coupled with the application of double-sided double-glass

components, the power generation can be increased by 10 percentage points to

15 percentage points.”

Pang Zifei, an engineer at Longyuan (Beijing) New Energy Design Institute Co., Ltd., said: "The tracking bracket is more suitable for use in

high-latitude centralized photovoltaic power stations.

The improvement in efficiency will be more obvious.”

Reduce risk

Against this background, tracking brackets have gradually gained market recognition. Since June, power generation companies such as China

Energy Construction and China Railway 11th Bureau have publicly held centralized procurement of photovoltaic brackets, among which tracking

brackets Pang Zifei revealed: "More and more projects require the purchase of fixed adjustable or tracking brackets. It can be said that tracking brackets

are the future development trend."

However, downstream terminals choose tracking brackets not only because they see the power generation advantage of tracking brackets.

"Reliability is also a very important criterion." Ma Weiming said,

branchThe rack has a unique protective capability. In extreme weather conditions such as strong winds, hail, and heavy snow, the rack can return to

a protective angle to protect the power station from the impact of extreme weather. "

"Among extreme weather disasters, 'wind disasters' pose the greatest challenge to photovoltaic power stations. During the actual operation of

the project, photovoltaic brackets were blown over, and

solidCertainlyThe bracket fell down while the tracking bracket was intact. "But this does not mean that all tracking brackets are better than fixed

brackets.

Onlysays,If the design is reasonable, the quality is qualified, the installation is correct, and the operation and maintenance are sufficient, the reliability of

the tracking bracket is very high.”

Ma Weiming said that the design and construction quality of the bracket directly affect the performance of the photovoltaic power station

in severe weather.

The hat's structure determines that in addition to considering the background component, it is also necessary to consider its own structural

vibration response, balanced wind load, 360° wind direction, multi-row interference effects, etc.

Adhering to high standards is an important factor in significantly improving the risk resistance of photovoltaic power stations under extreme

weather conditions and ensuring the long-term stable operation of photovoltaic power stations.

is the only influencing factor. Foundation treatment, installation technology, overall design and operation and maintenance management are

equally important. "

Looking forward to a new leap

Tracking brackets are also a new help to reduce the operating risks of photovoltaic power stations. As the demand for tracking brackets from

downstream terminals begins to increase, the development of the tracking bracket industry is accelerating.

The expert pointed out that with the increasing terminal demand and the uneven product quality, the tracking bracket industry needs to maintain

the bottom line of safety and formulate and improve relevant

Norms and standards will guide the high-quality development of the industry and form a virtuous circle.

"The industry threshold for tracking brackets is higher than that for fixed and fixed adjustable brackets, so we also pay special attention to the

quality performance of tracking brackets." said Pang Zifei.

Ma Weiming said: "Tracking brackets are different from building structures and require more scientific and reasonable wind engineering guidance.

The industry, from owners to design institutes to engineering general contractors, needs to have a deeper understanding of wind power.

Understand the wind engineering concept of tracking brackets. Within the company, we have established a quality management system to

ensure that each product meets high standards. Looking to the future, we will continue to increase

R&D investment to promote innovation in materials science and structural design, develop new high-performance materials and optimize

support structures. At the same time, we will strengthen cooperation with scientific research institutions and universities to promote

industry-university-research cooperation.

Integration to enhance technology reserves and innovation capabilities.”

In addition, Weng Kailei also pointed out: "So far, there are no relevant design specifications and standards for tracking brackets in China, and

the relevant specifications and standards are being formulated.

The photovoltaic industry is looking forward to the release of relevant requirements for tracking brackets, especially as the photovoltaic industry

becomes more and more mature, authoritative standards

While standardizing and tracking the stent industry, it can also promote the healthy, sustainable and positive development of the industry as a whole.”

Ma Weiming expressed the same view: "We call on the government and industry associations to formulate and promote strict industry standards

to ensure product quality and safety. We also hope to actively participate in the industry.

We will actively share advanced experience and technology through technical exchanges and industry seminars to promote the market.

The improvement of the overall level will promote the healthy development of the industry and ultimately contribute to the development of

global clean energy.”
