With the total installed capacity of 100MW, located in Ningxia Hui Autonomous Region, China, the solar power plant was successfully gird connected at the end of June in 2021, in which 30MW utilized Antaisolar’s Tai-universal solar tracker. What are the challenges presented by both climate and terrain Adjacent to the Tengger Desert, there are many days of high wind speed and dusty weather throughout the year, also extremely low temperature in winter and large temperature difference between day and night. The landscape of this region is soft soil with undulating hills, forming a complex terrain. Why Tai-universal was chosen for this project? In order to achieve optimal BOS and LCOE, and based on on-site survey, Antaisolar provided Tai-universal, the single-aixs 2P solar tracker for best match for bifacial modules, which can resist gust wind speed up to 45m/s. In the tuyere area, a redundant damping system was designed to further enhance the wind resistance of the project. As for the foundation, PHC solution was adopted to offer strong stability and thus reducing installation cost . Taking into account of complex terrain, Antaisolar offered different length of footing to nearly reduce the cost of land leveling. Besides, the solar tracker controller adopted 800Vac power supply from the nearest inverter. By this way, it is free of lithium battery and don’t require much cable cost and  routing construction, which enhanced performance of the overall system under extremely low temperatures. Moreover, the intelligent tracking algorithm has obvious advantages in this complex terrain. It can completely avoid shadow occlusion during the backtracking under different slopes, and can also improve the power generation of bifacial module in the case of low radiation and high reflectivity. It is estimated that it can achieve 6% annual power generation augment compared with the traditional tracking algorithm. Wind energy+ solar energy, strong complementary energy model for local grid This 30MW solar power plant is the one more cooperation with local EPC, Antaisolar advanced products and considerable expertise are well recognized for the past record. With abundant wind resources, the project is close to a GW-level wind farm, the complementary energy model of photovoltaic + wind energy serve as a new way for popularizing clean energy.

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.

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!
