South Korea’s Ministry of Trade, Industry and Energy (MOTIE) had estimated that around 4.1 GW of new PV plants were grid connected in South korea in 2020. If confirmed by official statistics, this result would compare to 3.8 GW in 2019 and 2.4 GW in 2018 and would make 2020 the most successful year ever recorded by the country. Antaisolar in partnership with GS global to jointly promote the clean energy utilization since 2020 and numerous solar farms has already connected to local grid ranging from utility-scale to distributed solar projects. For ground-mounted solar plants, either tailor-made or universal solar racking solution can be offered based on special needs. Antaisolar provided ground mounting solution with three main types of foundation, that is solar ground screw, concrete and driven piles. As for flat terrain, it’s commonly to adopt solar ground screw as a foundation. It can be installed by manual piling machine or pile driver machine without excavation and can be widely used in all kinds of geological conditions, such as foreshore, grassland, etc. While for uneven or sloping terrain, driven piles are best suited to these areas which have clay, gravel, dense sand and low water tables, where the ground has good soil cohesiveness. They are commonly used on large-scale projects as they have a number of advantages over other foundation types, including speed of installation, accuracy and low cost. For most of large scale solar plants in Korea, Antaisolar offers solar racking solution with single or double pile footing, which can also achieve great flexibility. Antaisolar has supplied a wide portfolio of solar racking solution ranging from KW scale to MW scale in South Korea. Armed with high quality control by in- house production and innovative design for efficient installing and high robustness, the solar mounting system has been recognized and under blossoming utilization for renewable projects.

On April 28-30, Green Energy Expo 2021 was held as scheduled in Daegu, South Korea. Antaisolar participated in the exhibition held by Korean partner GS Global, in which industry solar brands GCL, GOODWE and HT –SAAE also joined in the exhibition. During the event, Antaisolar presented with steel-aluminum combination, all-aluminum ground solar racking and rooftop solar racking, which are highly suitable for C&I distributed power stations and utility scale power stations in South Korea. The representative of Antaisolar said that the tailor-made rooftop solar racking developed for the Korean market, has become a attractive product received endless customer consultation and constant discussion. It’s said that the use of MAC steel and other steel roof solar racking has once become a common choice for rooftop solution while existing some roof bearing problems. The market urgently needs a type of system that can take into account the overall strength without affecting the roof load. The roof bracket system exhibited by Antaisolar turns out to be the top choice. Its excellent structural design and the lightweight and corrosion-resistant performance perfectly match the distributed solar plants, which has been unanimously recognized by visiting customers. Additionally, the ground solar racking for slope and complex ground has attracted many project owners and EPC for its proven track record. According to the Korea Photovoltaic Industry Association (KOPIA) statement, around 3 GW of new PV will be installed in the country this year. And South Korea currently plans to install 30.8 GW of solar by 2030. Antaisolar will continue to joint with local influential partners such as GS Global to co-develop solar market for carbon neutrality. Based on the vision of " Backbone for Solar World",  Antaisolar will focus on its brand positioning- the Expert in Hard & Core Technology for Solar Mounting & Tracking System, and strive to provide high-end customized solar racking solutions for global clients.

With the industry scaling toward hundreds of gigawatts of installed capacity, even 1% risk represents the potential for significant losses. As the utilization of large-scale solar plants accelerates into areas more prone to severe weather events, it’s of vital importance on how to manage those weather risks before initial designing. Thankfully, there are ways to mitigate extreme weather risks by addressing site-and region-specific conditions in advance and making strategic design, engineering, and procurement choices to lower those risks. There exists some solar plants damaged by extreme weather and thus caused huge loss. Actually, it’s a result of a combination of factors such as structural design, product quality, later operation and maintenance, etc. As a solar tracker manufacturer, Antaisolar has vast expertise in addressing the extreme weather challenge to large-scale solar plants. In this chapter Antaisolar is going to share some insights on structural design and see how it’s important for you to consider it when building a solar plant. In fact, the threat posed by strong wind is mainly caused by resonance. The multi-point drive solar tracker launched by Antaisolar can perfectly solve this problem. After the construction of the tracking support is completed, there will be a natural frequency f1, and the wind speed around the power station will cause the system to generate a vibration frequency f2. When f2 is close to or equal to f1, the system will resonate, which will cause twisting and lose stability, endangering the safety of the system. The multi-point drive solution is to largely increase f1, thereby widening the gap between the two and fundamentally solving the problem. Due to the use of multi-point drive technology, the system has one third wind torque three times higher natural frequency than traditional trackers. Additionally, the entire cost can be reduced by 5% to 20%, especially in areas with high wind pressure, the advantages will be more. The solar industry is increasingly recognizing that specialized approaches like wind tunnel testing are needed for dynamic wind loading because building codes simply don’t apply to these kinds of thin, flexible structures. Antaisolar’s Helios and Clytie series solar tracker are all tested and approved by CPP. Based on CPP’s leadership in understanding the effects of wind on solar collectors, their recommendations can enable Antaisolar designers and engineers to make modifications where needed and ensure the success design of a safe and efficient system. To sum it up , in order to keep it stable and safe under extreme bad weather, Antaisolar innovative solar trackers are developed from initial structural design to make it stay robust and it’s just one of the key factors for reducing solar project risk. In the next chapter , We will focus on another influencing factor in details, stay tuned!

Recently, one agricultural light complementary photovoltaic power station has made its grid-connection successfully in Japan with installed capacity of the 820.8KW. The whole project adopted Antaisolar agricultural farmland mounting system with AL6005-T6 structure to ensure corrosion resistance and stability. In this project, Antaisolar proposed a bottom fixing solution . Compared with the traditional top-down installation method, there is no need to climb brackets and stepping on panels. Therefore, it realized the convenient installation of fixing the solar panel from bottom and thus improves the efficiency and safety of construction.  Besides, in order to cope with the sloping terrain, Antaisolar engineers provided different column length and the exposed length of the ground screw after carefully calculations, which perfectly matched the slope application and deeply recognized by our client. In addition, there are numerous of the agricultural light complementary photovoltaic power station in Japan adopted Antaisolar solar racking solutions, with capacity ranging from 100KW to 1MW.  In South korea, there existed a 400KW agricultural light complementary photovoltaic power stations which utilized Antaisolar solar racking system. It is not only the first aluminum mounting structure for agricultural PV plant but also the biggest PV plant till now in Korean territory. The combination of agriculture and photovoltaic applications is a new model. It will not change the nature of land use, and thus can save land resources. Agricultural light power plant can not only effectively use solar energy resources to output of clean green energy, but also to achieve efficient cultivation, which realized the comprehensive utilization of land resources and solar energy resources.
