  • How to Choose the Best TCU Solution for Your Solar Tracker System

    How to Choose the Best TCU Solution for Your Solar Tracker System In the dynamic world of solar energy, choosing the right technology Tracking Control Unit (TCU)/solar tracker control unit for your solar tracker system can significantly influence your project’s success. With various options available in the market, understanding the key factors to consider will help you make an informed decision that maximizes efficiency, reliability, and return on investment. Here’s a guide to help you choose the best TCU solution for your solar tracker system. 1. Understand Your System Requirements Before diving into the specifics of different TCUs, it’s essential to have a clear understanding of your solar tracker system’s requirements. Consider the following questions: – What type of solar trackers are you using (single-axis or dual-axis)? – What is the scale of your project? – What are the environmental conditions at the installation site? – What level of precision and control do you need? 2. Evaluate Compatibility Ensure that the TCU you choose is compatible with your existing or planned solar tracker system. Compatibility includes both hardware and software aspects. The TCU should seamlessly integrate with your trackers, sensors, and other control systems. Look for TCUs that support standard...

  • Maximizing Solar Energy Output: The Single-Axis Solar Tracking System

    In the pursuit of sustainable energy solutions, solar power stands out as a frontrunner. Its abundant, clean, and renewable nature makes it a key player in the transition towards a greener future. However, to truly harness the potential of solar energy, maximizing its efficiency is paramount. This is where innovative technologies like single-axis solar tracking systems come into play.   Understanding Solar Tracking Systems   Solar tracking systems are mechanisms that orient solar panels or arrays to follow the path of the sun, optimizing the angle of incidence for maximum energy capture throughout the day. While fixed solar panels are stationary and positioned at a fixed tilt angle, solar tracking systems dynamically adjust the orientation of solar panels to track the sun’s movement.   The Efficiency Boost of Single-Axis Tracking   Single-axis solar tracking systems operate by rotating solar panels along a single axis, typically the north-south axis. This rotation allows the panels to follow the sun’s daily east-to-west path across the sky. While not as complex as dual-axis systems, which also adjust for seasonal variations in the sun’s position, single-axis trackers offer significant efficiency gains compared to fixed installations.   Key Benefits of Single-Axis Solar Tracking Systems   Increased...

  • Wheat grows better in agrivoltaic system

    New findings from Italy suggest that wheat cultivation in elevated agrivoltaic systems may lead to better-quality crops with enhanced nutritional value, particularly beneficial for livestock. A collaborative effort by the CNR Institute for Bioeconomy, the University of Florence, and agrivoltaic specialist REM Tec srl, investigated the performance of wheat in an agrivoltaic setup spanning 11.4 hectares in Borgo Virgilio, Mantua province. The experiment utilized 7,680 Bisol panels and 768 trackers positioned at a height of 4.5 meters, covering approximately 1.3 hectares. Dividing the area into sections, the team compared wheat growth under different levels of photovoltaic coverage. They observed three sections with a ground coverage ratio (GCR) of 13%, three with a GCR of 41%, and three reference sections devoid of panels and shading structures. Over two years of experimentation, researchers noted a limited reduction in wheat yield during the waxy maturation phase under standard trackers (GCR = 13%). However, in panels with increased shading (GCR = 41%), the reduction reached 29.6%. Lucrezia Ghidesi, Business Developer at REM Tec srl, highlighted, “The reduction in irradiation significantly altered the stature of wheat plants, impacting the quality of the fodder biomass.” Analyzing various parameters including dry matter, ash, crude protein content, and...

  • Plastic bearings used in solar tracking system

    Introduction The utilization of bearings in the photovoltaic sector is driven by the need to create a partially movable structure that enables solar panels to track the sun’s position and maximize solar energy capture throughout the day. The bearing assembly plays a crucial role in the tracker system. Not only does it facilitate the rotation of the torque tube for sun tracking, but it also ensures the secure attachment of the torque tube to the foundation piles, enabling it to withstand significant vertical, horizontal, and axial loads. Without bearings, a single-axis tracker would be a fixed structure incapable of adjusting to the sun’s movement. A well-designed bearing system enables efficient tracking, minimizing energy losses caused by friction. It also facilitates faster assembly and helps mitigate the twisting forces generated during the installation of the foundation piles. In summary, bearings are essential components in photovoltaic trackers as they enable solar panels to track the sun, optimize energy capture, and ensure structural stability under various loads Materials The selection of the appropriate plastic material for bearings is of utmost importance as it directly impacts their performance in terms of interactions, friction, and resistance to various loads. Solar Tracker nowadays usually employs different...

  • The photovoltaic tracking system that “pursues” the sun breaks the “passive” situation of traditional light storage power stations

    The new photovoltaic power station has changed the mode that the traditional photovoltaic storage power station can only receive light passively and fixedly, and drives the photovoltaic modules through the tracking bracket to actively “chase” the sun to obtain the maximum power generation. In recent years, with the rapid development of the world economy, energy consumption has increased dramatically, the reserves of traditional non-renewable energy have decreased rapidly, and the ecological environment has been further damaged, and people’s demand for renewable energy has become more and more intense. Therefore, clean and renewable energy, including photovoltaics, is gradually favored by all countries. In 2022, China’s new installed photovoltaic capacity will be 87.41 GW, a year-on-year increase of 59.3%. It is predicted that by 2050, 70% of China’s total annual installed capacity will come from solar and wind power generation. Therefore, how to use new energy storage technology to improve the utilization efficiency of new energy has become the top priority of the development of the new energy industry in the future. However, with the development of photovoltaic and its energy storage technology, a problem is deeply lingering in people’s minds: due to the rotation of the earth, the sun is changing...

  • What factors mainly determine the power generation of photovoltaic power plants?

    The electricity generation of a photovoltaic (PV) power station primarily depends on several key factors:   Sunlight Intensity and Duration:   The amount of sunlight received by the solar panels directly influences their efficiency in converting solar energy into electricity. Regions with higher sunlight intensity and longer durations of sunlight generally yield greater energy production.   Solar Panel Efficiency:   The efficiency of the solar panels themselves is a critical factor. Higher efficiency panels can convert a larger percentage of sunlight into electricity.   Orientation and Tilt of Solar Panels:   Proper alignment of solar panels towards the sun and an optimal tilt angle can maximize the amount of sunlight captured, enhancing overall energy production.   Weather Conditions:   Weather factors such as cloud cover, temperature, and atmospheric conditions can impact the amount of sunlight reaching the solar panels. Cloudy or overcast days may reduce the power output.   Geographical Location:   The geographical location of the solar installation affects the angle and duration of sunlight exposure. Different latitudes experience varying amounts of sunlight throughout the year.   Shading and Obstructions:   Shading from nearby structures, vegetation, or other obstructions can significantly reduce the efficiency of solar panels. Ensuring an...
