In the world of photovoltaic (PV) tracking systems, the choice of bearings is crucial for optimizing performance and ensuring durability. While plastic bearings have been commonly used due to their cost-effectiveness and lightweight nature, aluminum shell bearings are increasingly being favored. Here’s why aluminum shell bearings often provide superior performance compared to their plastic counterparts. Durability and Strength One of the most significant advantages of aluminum shell bearings is their enhanced durability and strength. Aluminum is a robust material that can withstand heavy loads and high stress, making it ideal for the demanding conditions of PV tracking systems. In contrast, plastic bearings may degrade under prolonged exposure to environmental stresses and mechanical loads, leading to premature failure and reduced system reliability. Temperature Resistance Aluminum shell bearings offer superior temperature resistance compared to plastic bearings. Solar tracking systems are exposed to a wide range of temperatures, from scorching heat to freezing cold. Aluminum maintains its structural integrity and performance across these temperature variations, while plastic bearings can become brittle or soften, affecting their functionality and lifespan. Load Capacity The load capacity of aluminum shell bearings is generally higher than that of plastic bearings. This is particularly important in PV tracking systems,...
In solar tracking systems, the choice of bearings for solar trackers is crucial. It not only affects the overall stability and lifespan of the system but also influences maintenance costs and operational efficiency. Common bearing materials in the market include metal and plastic. In this article, we will explore why you should opt for metal bearings with aluminum alloy housing and POM material sliding blocks rather than all-POM plastic bearings. Higher Strength and Rigidity Aluminum housing bearings, offer significantly higher strength and rigidity. This enables them to provide more reliable support in solar tracking systems under constantly changing loads, reducing the risk of deformation and damage. In contrast, all-POM plastic bearings can easily deform under high-stress environments, affecting system accuracy and stability. Superior Wear Resistance and Longevity POM sliding blocks are renowned for their excellent wear resistance, but this advantage is further enhanced when paired with metal housing. The metal housing provides a more robust outer protection, allowing the sliding block to maintain optimal performance under harsher conditions for a longer period. All-POM bearings may experience accelerated wear over time, leading to frequent replacements and maintenance. Better Heat Resistance The heat resistance of aluminum alloy far surpasses that of...
According to a recent article by PVTECH. North America is expected to be the major global market for solar trackers in the upcoming years. In contrast, over 750GW of trackers will be installed globally between 2024 and 2030, according to a recent report published by S&P Global. In the Solar Tracker Market Report 2024, S&P Global said about 60GW of trackers were installed globally in 2023 and over 80GW are expected in 2024. In 2027, more than 100GW of trackers will be installed worldwide, most coming from North America and the Europe, Middle East, and Africa (EMEA) markets. Overall, 752GW of trackers will be installed between 2024 and 2030. Of this capacity, 39% will be from North America, followed by EMEA (31%), the Asia-Pacific region (22%) and South America (8%). The North American market is expected to grow to 50GW annual additions by 2030, with most installations in the US. By 2026, installations in the US are forecast to increase to over 40 GW. Although the Mexican utility-scale solar PV market has decreased from its historical highs during 2018-2020, its tracker market is expected to grow and exceed 1GW per year from 2028 onwards. In the EMEA market, tracker installations in Spain are forecast to fall steadily starting...

In the rapid development of photovoltaic power generation systems, the market has favored Horizontal Single Axis Solar Trackers (HSAT) due to their high power generation rate, low maintenance cost, and simple installation. With the global installation of horizontal single-axis trackers reaching 92GW, a critical issue that has consistently concerned project owners is shading. The key to addressing this issue lies in an advanced algorithm embedded in the solar tracking controller. As a talented developer in this field, Good Future proudly introduces our Tracking Control Unit (TCU), equipped with an advanced Backtracking Algorithm to ensure optimal performance under all conditions. What is the Backtracking Algorithm? The backtracking algorithm is a crucial innovation in solar tracking technology. Its primary function is to dynamically adjust the angle of solar panels to minimize mutual shading between them, thereby enhancing the system’s overall energy output. This is particularly significant for Horizontal Single Axis Solar Trackers (HSAT), where panels are typically arranged closely together, making them prone to shading issues. How Does the Good Future TCU’s Backtracking Algorithm Work? 1. Shade Avoidance: At the core of Good Future’s backtracking algorithm is the goal of reducing mutual shading between panels. During low solar angles (such as in...
As the proportion of horizontal single-axis solar trackers in global solar power systems continues to increase, project owners are increasingly concerned about how these trackers can ensure project safety under the rising frequency of extreme weather conditions. The Horizontal Single-Axis Solar Tracker (HSAT) is notable for its efficiency and adaptability. However, these systems must be designed to withstand and operate under extreme weather conditions, such as heavy rain, flooding, snowfall, and strong winds. The seamless operation of HSAT systems in such environments relies heavily on the coordinated efforts of several critical modules: the Tracker Control Unit (TCU), Network Control Unit (NCU), wind sensors, and GPS modules. Tracker Control Unit (TCU) The TCU is the brain of the solar tracker system. It controls the movement of the solar panels to ensure they are always positioned optimally to capture the maximum amount of sunlight. This unit processes data from various sensors and modules to adjust the angle of the panels throughout the day. Network Control Unit (NCU) The NCU manages communication between multiple tracker units across a solar farm. It ensures that all trackers operate in a coordinated manner, sharing data and making collective decisions to optimize performance and safety. Wind Sensors...
