This paper presents an optimisation methodology that takes into account the most important design variables of single-axis photovoltaic plants, including irregular land shape, size and configuration of the mounting system, row spacing, and operating periods (for backtracking. This paper presents an optimisation methodology that takes into account the most important design variables of single-axis photovoltaic plants, including irregular land shape, size and configuration of the mounting system, row spacing, and operating periods (for backtracking. The application belongs to the field of photovoltaic supports, and discloses a large-span flat single-axis tracking type flexible photovoltaic support system, which comprises a load-bearing cable system with a fishbone structure, wherein the load-bearing cable system comprises a first cable with a. The ground tracking bracket is suitable for installation in large commercial, public utility power stations, mountainous and uneven areas. The product has a sturdy structure and strong stability. These machines shape metal strips—typically aluminum, galvanized steel, or stainless steel—into precise profiles that support and secure solar. No description has been added to this video.
