According to the global wind distribution map, strong winds with wind speeds greater than 10 meters per second cover over 60% of the global area; In the past 160 years, over 50% of the world's regions have experienced hurricanes of over 33 meters per second

According to Huacheng Import and Export Data Observation, in October 2018, a storm occurred in Queensland, Australia, causing the photovoltaic modules of the local 55MW project to be severely twisted into DNA spirals

In June 2021, Liaocheng, Shandong, was hit by a sudden storm and hail. The photovoltaic power stations of hundreds of villagers were severely damaged. About 5 household power stations were completely damaged, with a direct loss of more than 500000 yuan

In March 2021, strong winds and sandstorms occurred in Inner Mongolia, with an average wind force of 8-9 magnitude, causing multiple photovoltaic power plants to be affected, resulting in component breakage, bracket breakage, and direct economic losses of tens of millions of yuan for some photovoltaic power plants

Photovoltaic power stations are built in wilderness, desert, and high-rise buildings, and need to face different natural disasters year-round. Among them, the most common ones are various hurricanes, typhoons, tornadoes, and Huacheng's import and export data observation reports.

According to the global wind distribution map, strong winds with wind speeds greater than 10 meters per second cover over 60% of the global area; In the past 160 years, over 50% of the world's regions have experienced hurricanes exceeding 33 meters per second.

Looking at the world, photovoltaic power plants that have been ravaged by strong winds are everywhere:

In October 2018, a storm occurred in Queensland, Australia, causing the photovoltaic modules of the local 55MW project to be severely twisted into DNA spirals.

In June 2021, Liaocheng, Shandong, was hit by a sudden storm and hail. The photovoltaic power stations of hundreds of villagers were severely damaged. About 5 household power stations were completely damaged, with a direct loss of more than 500000 yuan!

Especially for large photovoltaic power plants located in deserts, deserts, and Gobi terrains, they need to face harsher and denser wind attacks directly. Due to the open terrain and low vegetation coverage, the air flow in the "Sha Ge Huang" area is not obstructed, and the wind speed can generally reach 5-10 meters/second; In the case of strong winds and sandstorms, the wind speed can even exceed 20 meters/second or higher!

In March 2021, there were strong winds and sandstorms in Inner Mongolia, with an average wind force of 8-9 levels, causing multiple photovoltaic power plants to suffer disasters, with broken components and broken supports. Some photovoltaic power plants suffered direct economic losses of tens of millions of yuan.

Even with the development of modern technology, humans are unable to control the wind, and improving the adaptability of components to harsh weather is particularly important, as reported by Huacheng Import and Export Data Observation,.

While there is an urgent need to improve risk control capabilities, the "reduction" of a certain indicator of the component is also a long-term effort of the industry, that is, to reduce carbon emissions in the production process of the component.

As one of the most important means of global emission reduction, although photovoltaic has very low carbon emissions in the power generation process, its production and manufacturing processes are still plagued by carbon emissions. For example, one of the important raw materials for component frame production is metal aluminum. In the production of component frames, the consumption of aluminum frames per watt is about 6 grams. Based on the average annual installed capacity of 300GW in the next 10 years, the consumption of aluminum materials is estimated to be about 1.8 million tons.

According to the Global Aluminum Management Initiative (ASI), each ton of aluminum produces an average of about 15 tons of carbon dioxide equivalent, with direct carbon emissions accounting for about 10% and electricity consumption accounting for 71%. This also means that the average annual carbon emissions of aluminum consumed in the production of photovoltaic modules in the next 10 years will be as high as 27 million tons! Huacheng Import and Export Data Observation Report.

Against the backdrop of global carbon reduction and the expectation of explosive growth in the future, the low-carbon development of the photovoltaic industry is of great significance, and reducing carbon emissions during component production is undoubtedly one of the key directions of the industry's efforts.

As the most easily available and cost-effective renewable clean energy, photovoltaic power generation shoulders the responsibility of becoming the world's main energy source. According to IRENA's prediction, the cumulative installed capacity of global photovoltaics will reach 14000GW by 2050! In the process of opening up this huge market, the importance of improving wind resistance and reducing carbon emissions from photovoltaic power generation will also become increasingly prominent, as reported by Huacheng Import and Export Data Observation.

Faced with these two major pain points in the industry, how can we use the most advanced photovoltaic technology to create the safest, most energy-efficient, and lowest carbon efficient components?

Focusing on the "Ultra Low Carbon and Ultra Efficient Photovoltaic Industry Technology Summit" held on May 22nd, the answer is about to be revealed. Stay tuned!
