As the world increasingly looks to renewable energy sources to combat climate change and meet growing energy demand, solar photovoltaic (PV) systems have become a key player in the energy landscape. Traditionally, solar panels are mounted on roofs or ground structures at an Angle to maximize exposure to sunlight. However, a new and innovative approach is gaining traction: vertical solar photovoltaic systems.
#### Learn about vertical solar photovoltaic systems
Vertical solar photovoltaic system includes the installation of solar panels in the vertical direction, vertical installation, that is, the photovoltaic module inclination 90° installation, this installation mode can not only improve the utilization of solar energy, but also effectively save land, the photovoltaic power station and agricultural activities to a greater degree of integration, has become an emerging installation of agricultural photovoltaic. At the same time, vertical installation can also be applied in other “photovoltaic + scenarios” such as highway guardrail and household fence. The high double-sided ratio of heterojunction components compared to other technical components gives them significant power generation advantages in vertical installation scenarios.
#### The main advantages of vertical solar PV systems
1.Optimize space use :
In densely populated urban areas, horizontal space is often limited. Vertical solar installations take advantage of otherwise unused vertical surfaces such as the sides of buildings, noise barriers along highways, and other structures, thereby increasing the overall capacity of solar power generation without requiring additional land. From the perspective of projection area, compared with conventional inclined installation, vertical installation mode components occupy a positive and low area, which greatly improves the space utilization rate. And the vertical system construction does not need to change the terrain, can better play the original economic attributes of the land (such as agricultural and animal husbandry land), and maximize the value of solar power generation and the value of the land itself.
2.Improves sunlight capture under certain conditions :
Depending on geographic location and seasonal variations, vertical solar panels can capture sunlight more efficiently at certain times of the day or year. For example, at high latitudes, where the sun stays low on the horizon, vertical panels can receive more direct sunlight than tilted panels.
3. Reduce shading problems:
In urban environments, shading from nearby buildings, trees, or other structures can significantly affect the performance of solar panels. Vertical installation can alleviate these shading issues by placing the panel in a position where it is less likely to be blocked.
4. Higher comprehensive utilization rate of solar energy
Due to the overall optical properties of the packaging glass and components, about 5% of the light shining on the components will inevitably be reflected off. When the component is installed at an inclined Angle, this part of the light is reflected into the sky, resulting in wasted energy and even light pollution. However, in a vertical photovoltaic system, some of the light is reflected to nearby plants or other photovoltaic arrays for reuse.
5. Easy to maintain:
Vertically mounted panels are generally easier to clean and maintain because they are less prone to accumulating dust, debris, and snow than horizontally mounted panels. Vertical installation prevents dust and dust accumulation of the components (especially at the bottom), eliminating the need for frequent cleaning, reducing power generation losses and increasing reliability of the PV modules while reducing operation and maintenance costs. In addition, in extremely cold areas and cold seasons, vertical installation can avoid snow cover, both to minimize the loss of power generation, and to avoid the risk of mechanical load failure caused by excessive snow.
Conclusion
Vertical solar photovoltaic systems are a promising and innovative way to scale up solar power generation, especially in urban environments where horizontal space is limited. By utilizing vertical surfaces, these systems can enhance the sustainability of buildings and infrastructure, reduce shading issues, and contribute to the visual appeal of urban landscapes. As technology continues to evolve and the demand for renewable energy grows, vertical solar photovoltaic systems will play an increasingly important role in the global transition to energy.
