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...
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 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...
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...
Southeast Asia is one of the most profitable solar markets in the world, with the fastest growth and one of the most promising regions for the global solar photovoltaic industry. By the end of this year, the scale of the Southeast Asian solar energy market is expected to be 27GW, and it is expected to reach 43GW in the next five years, with a compound annual growth rate of over 10.2% during the forecast period. In the medium term, factors such as increasing renewable energy installations to reduce carbon emissions and declining prices of solar photovoltaic modules have driven the solar energy market. On the other hand, the increasing popularity of alternative renewable energy technologies such as hydropower is expected to hinder market growth during the research period. Nevertheless, the government’s support policies for renewable energy and technological advancements in solar equipment are expected to increase the opportunities for solar companies to install solar photovoltaic power plants in the region in the coming years. Vietnam is expected to become the largest market in Southeast Asia as its demand for electricity continues to increase, the number of renewable energy installations continues to increase, and it is connected to the...
Single-axis and dual-axis solar trackers are both technologies designed to optimize the orientation of solar panels to maximize their exposure to sunlight and increase energy production. However, they differ in terms of their tracking capabilities and complexity.
