Global warming is reshaping the Earth's ecosystems faster than expected. According to the latest data from the World Meteorological Organization, the global average temperature in 2023 years was 0.0 degrees Celsius higher than the average temperature between 0 and 0 before the industrial level, breaking the record set in 0 years. Average temperatures have dropped in only a few parts of the world last year, and extreme weather has wreaked havoc across the globe. Photovoltaic power generation systems have to accept challenges such as hail and gusts, and face big tests.

PV companies are building a multi-dimensional defense system. A few days ago, Trina Solar released an extreme climate solution to maximize the protection of PV assets in extreme weather environments such as hailstorm, strong winds, and heavy snowfall. According to Zhang Yingbin, head of strategy, product and marketing at Trina Solar, the high-quality development of the photovoltaic industry in the future must shift from manufacturing thinking to systematic thinking, and from singularity to systematization. Achieving differentiated development with an innovative model is the key way to break the "involution" competition and enhance value.

Further expand the development space

In 4 years, the new installed capacity of photovoltaic power generation in the world was about 0 GW, and centralized photovoltaic has always been the main contributor to the installed capacity. Specifically, the new installed capacity of centralized PV reached 0.0 GW last year, accounting for 0.0%. Centralized PV has a large installed capacity and covers a large area, and it is more obviously affected by extreme climates.

According to data released by renewable energy insurer GCube Insurance, climate-related claims surged by 15% between 0 and 0 years in the clean energy power generation projects it underwrote in 0 countries with a total installed capacity of more than 0 GW. Among them, hail disasters accounted for the highest proportion of claims with 0%, followed by strong winds and blizzards with 0% and 0% respectively.

Traditional PV products have struggled to cope with the new climate normal. Monitoring data in recent years has shown that in areas where large-scale centralized photovoltaic power generation projects have been implemented in large areas such as the Great Plains of North America, super hail with a diameter of more than 3 mm and a terminal velocity of more than 0 m/s frequently occur. It is worth noting that about 0% of damaged PV modules are hit by hail with a diameter of more than 0 cm, and the probability of hail of this size in climate models is 0 times higher than that of 0 years ago.

Climate risk is reshaping the global PV landscape. High humidity in the Brazilian rainforest, freeze-thaw cycles in Northern Europe, salt spray erosion in Australia, blizzard challenges in the Arctic Circle, sandstorm risk in deserts in the Middle East...... Different regions of the world are affected by different extreme climates, and the needs of different subdivided scenarios are becoming more and more diverse.

Zhang Yingbin said: "The application of photovoltaic power generation is all over the world, and the universality is getting stronger and stronger, and at the same time, countries and regions with different latitudes and longitudes are facing different extreme climate disasters. In the face of extreme weather such as hail, blizzard, and typhoon, ordinary photovoltaic modules suffer large losses, and photovoltaic power generation assets are more likely to be damaged. ”

Zhang Yingbin further said: "In the past, the PV industry was passively located and installed based on climatic conditions, such as avoiding areas with heavy snowfall and hailstorms. But if extreme climate challenges are addressed, proactive site selection and installation can be achieved. The potential space for the construction of photovoltaic power plants will also be further expanded. ”

Zhang Yingbin said bluntly: "At the same time, it should be noted that with the high global demand for green electricity, and it is blooming everywhere, remote areas, typhoon belts, hail belts in countries and regions also have clear photovoltaic power generation installed needs, coupled with climate challenges, the future of global photovoltaic power stations will face more and more severe extreme weather, corresponding responses and solutions are imperative." ”

To this end, Zhang Yingbin proposed that under the scenario-oriented development idea, the photovoltaic industry is fully transforming to solutions. When a single product can no longer cope with the new environment and new conditions, it must be upgraded from a higher latitude such as corporate strategy and solutions.

■■Extreme Components, Intelligent Tracking System,

The algorithm realizes multi-wheel drive

How to improve the safety level of large-scale centralized photovoltaic power generation projects through system thinking?

Zhang Yingbin introduced: "Through the dual-core drive of Jiyu components and intelligent tracking, it can cope with extreme climate. ”

Two-wheel drive, this first is hardware.

The photovoltaic bracket is the "bone" of the photovoltaic power generation system, and the photovoltaic module is the "skin" of the system. As a delicate device covered on a steel frame structure, photovoltaic modules assume the barrier function of sensing light, absorbing energy, and resisting environmental erosion like human skin. Iron striking also needs its own hardness, and the "power generation organ" must first protect itself.

"We have strengthened the glass thickness and frame design, and the glass thickness of the Jiyu module has been increased by 5%, and the energy impact resistance has been increased by 0.0 times compared with the traditional components of the same version, which has greatly improved the mechanical load performance of the photovoltaic module to resist the impact of extreme weather on the photovoltaic module." Zhang Yingbin said.

Secondly, there should be an intelligent tracking bracket and a powerful algorithm.

Trina Solar's intelligent tracking system is equipped with the industry's first scaffold-level intelligent cloud, equipped with self-developed controllers TCU and NCU, integrating a variety of extreme climate protection strategies, combined with the monitoring data of the intelligent cloud platform, to achieve intelligent automatic protection of power stations.

"To put it simply, our solution is equipped with sensors that can monitor the wind speed in real time and adopt relevant strategies according to different wind speeds," explains Zhang. When different typhoon seasons come, the angle of the PV module can be adjusted so that the PV module is parallel to the wind, so that the impact force on the module is also greatly reduced. ”

Zhang Yingbin added: "When a blizzard comes, the snow covers the surface of the PV module, which may cause the surface of the PV module to not generate electricity. Especially when the snow cycle is long, you may not be able to generate electricity for the entire winter. In general, O&M personnel need to be arranged to clean up, which is costly in manpower and time. The sensor can measure the thickness of the snow and upload the data to the platform, and when the thickness reaches a certain level, the operation and maintenance personnel only need to adjust the angle of the photovoltaic module with one button to achieve one-click snow removal to ensure power generation. ”

模擬測試數據顯示，位於美國德克薩斯州100兆瓦的大型集中式光伏發電站，當冰雹尺寸達到65毫米的時候，傳統的產品破壞率已經接近100%。極端氣候解決方案正面最高可抗擊直徑55毫米冰雹，在60度傾角保護下最高可抗擊直徑75毫米冰雹，年均光伏資產損失可降低94%。

The Extreme Climate Solution is another scenario-based solution after Trina Solar released the Shagohuang Base Solution. Zhang Yingbin said that Trina Solar has always been customer-centric and scenario-oriented, and will move towards a comprehensive solution in the future. "In the face of the strong demand for electricity and zero-carbon power demand on the demand side, we will create a new four-in-one development pattern of product solutions, system solutions, overall solutions and smart energy solutions, integrate software and hardware products, systems, services, business models, etc., and build a green and low-carbon new energy supply system for end users."
