Can fixed adjustable photovoltaic brackets help reduce shading losses?
Publish Time: 2025-08-04
With the growing global demand for clean energy, solar power is gaining increasing attention as a clean and sustainable form of energy. However, the energy collection efficiency of solar panels is affected by a variety of factors, with shading being a common issue. Fixed photovoltaic brackets, due to their fixed mounting angle, often perform poorly when facing shadows cast by surrounding buildings, trees, or other obstructions. In contrast, fixed adjustable photovoltaic brackets, through their flexible angle adjustment, can significantly reduce shading losses, thereby improving overall power generation efficiency.
1. Flexible Angle Adjustment Mechanism
The greatest advantage of fixed adjustable photovoltaic brackets is their ability to adjust their angle according to time of day and season. This flexibility allows users to optimize the orientation of the photovoltaic panel based on the sun's altitude and azimuth, ensuring maximum sunlight throughout the day. Especially in the morning and evening, when the sun is low in the sky, appropriate angle adjustment can avoid shadows cast by obstructions such as buildings and trees. At noon, when the sun is directly overhead, adjusting the angle can also help maximize direct sunlight absorption and reduce energy loss due to shading. Furthermore, for installation sites located in complex terrain or with numerous obstacles, fixed adjustable photovoltaic brackets can fine-tune their angle to avoid localized shadows and ensure that each panel receives the maximum amount of sunlight. For example, in urban environments, buildings are often close together, easily leading to mutual shadowing. Properly setting the photovoltaic bracket angle can effectively mitigate this effect and improve the overall power generation efficiency of the system.
2. Adapting to Seasonal Changes
The sun's position varies significantly throughout the year. It is higher in the summer and lower in the winter. Traditional fixed photovoltaic brackets struggle to maintain optimal sunlight angles throughout the year, resulting in low energy collection efficiency in certain seasons. Fixed adjustable photovoltaic brackets, however, allow users to adjust the bracket angle seasonally to adapt to varying sunlight conditions. For example, in the summer, the bracket can be tilted less to better capture high-angle sunlight, while in the winter, it can be tilted more to capture lower-angle sunlight. This seasonal adjustment not only helps increase daily energy output but also significantly reduces losses caused by shadowing. This is especially true around the winter solstice, when the sun rises and sets relatively low. If the bracket angle is not adjusted promptly, it can easily be obscured by surrounding obstacles. Therefore, regularly adjusting the angle of the fixed adjustable photovoltaic bracket is a key measure for maintaining high efficiency.
3. Reducing the Impact of Shadows in the Morning and Evening
Morning and evening are times of day when sunlight is weakest and most susceptible to shadows. At these times, the sun is near the horizon, and light must travel a long path through the atmosphere to reach the ground. Any obstacles during this time can cause significant shadowing. Fixed photovoltaic brackets, unable to adjust their angles in real time, often suffer significant energy losses during these times. Fixed adjustable photovoltaic brackets, however, can adjust their angles to optimize the angle of incidence between the photovoltaic panel and sunlight, minimizing the impact of shadows. Specifically, in the morning and evening, sunlight strikes from the side. If the photovoltaic panel remains horizontal or vertical, it is easily blocked by nearby buildings or other obstacles. Appropriately lowering or raising the angle of the photovoltaic panel allows sunlight to strike the panel surface more directly, improving energy conversion efficiency. This feature is particularly useful for photovoltaic systems located in urban environments with densely populated buildings.
4. Optimizing Spatial Layout and Array Design
In large-scale photovoltaic power plants, rationally planning the spatial layout of the modules is crucial. Fixed adjustable photovoltaic brackets not only help individual panels avoid shadows but also optimize overall array layout. By finely adjusting the angle of each row of panels, limited land resources can be fully utilized while ensuring that panels do not block each other. This not only increases energy production per unit area but also reduces overall efficiency losses caused by shadowing. Furthermore, fully considering potential shadowing sources (such as new buildings and vegetation) during the design phase and allowing for adjustments is a key strategy for ensuring long-term stable power generation. Fixed adjustable photovoltaic brackets provide this flexibility, allowing for simple angle adjustments to maintain high power generation efficiency even if the surrounding environment changes over the next few years.
In summary, fixed adjustable photovoltaic brackets significantly reduce the impact of shadowing on solar systems through their flexible angle adjustment mechanism, ability to adapt to seasonal changes, reduced shadowing during morning and evening hours, and optimized spatial layout. They not only improve the energy collection efficiency of photovoltaic panels but also enhance system reliability and stability.
