•  Case studies about multiple solar plants applied in South Korea
    Project News May 21, 2021 Case studies about multiple solar plants applied in South Korea
    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.

  • How to reduce solar project risk for extreme weather from initial structural design?
    Project News April 27, 2021 How to reduce solar project risk for extreme weather from initial structural design?
    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!

    Project News April 14, 2021 Antaisolar offered solar racking solution for Agriculture and light complementary power stations
    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.

    Market Potential A majority of Madagascar’s renewable energy potential remains unharnessed. The country has high hydro, solar, and wind potential and considerable biomass resources. In its New Energy Policy (NEP), the government identified an ambition to produce 85% of the country’s power from renewable sources by 2030 Madagascar has a large solar energy potential. Almost all regions of Madagascar receive over 2,800 hours of sunshine per year, with the daily solar radiation ranging from 1,500 to 2,100 kWh/m2. PV systems are currently utilized for powering public buildings such as health clinics, as well as off-grid community electrification solutions. A few foreign companies are assisting with various electrification projects on a small-scale (i.e. solar-powered pumps for clean water) Solar farms in Madagascar, solar racking provided by Antaisolar The total capacity of this ground project is 6MW, which is comprised of several projects ranging from 1to 2MW and installed in Diego, Tamatave, Majunga and other places. Due to the frequent cyclone season, the maximum wind speed is very high and up to 60m/s. Madagascar has a tropical rainforest climate, with lots of rain, flat but muddy land. Antai Solar adopted concrete foundation with aluminum mounting system with measurement and calculation by the engineer for ensuring sufficient strength in cyclone weather. Antai Solar provide the solar mounting solutions through OCEAN TRADE, and the project was successfully completed under the efforts of parties. Among one of the projects, Mr Andry Nirina Rajoelina, president of Malagasy, had visited and inaugurated the 2MW solar hybrid project in Tamatave.
