Unlock New Poses! How can heterojunction modules combined with vertical installation unleash their amazing potential?
Vertical installation, where PV modules are positioned at a 90-degree angle, not only improves the utilization rate of solar energy but also effectively saves land, facilitating greater integration of photovoltaic power stations with agricultural activities. This innovative approach has emerged as a new type of installation method for agricultural photovoltaics. Importantly, vertical installation can be applied in other "PV + scenarios" such as highway guardrails and household fences. Compared to other technical components, heterojunction modules offer a significant power generation advantage in vertical installation scenarios due to their high bifaciality. In this mini-classroom, let's delve into vertical installation and explore how components perform in this novel application.
Why choose vertical installation?
Higher Space Utilization
From the perspective of projected area, compared with conventional tilted installation, the vertical installation method occupies a significantly smaller footprint, greatly improving space utilization.
Moreover, the construction of vertical systems does not require changing the terrain, and can better utilize the original economic attributes of the land (such as agricultural and animal husbandry land), maximizing the value of both solar power generation and the land itself.
Easier to maintain
Vertical installation can prevent the components (especially at the bottom) from accumulating dust and dust, eliminating the need for frequent cleaning. This reduces the power generation loss of photovoltaic modules, enhances reliability, and reduces operation and maintenance costs.
Additionally, in extremely cold regions and during cold seasons, vertical installation helps prevent snow accumulation, thereby minimizing power generation losses and mitigating the risk of mechanical load failure due to excessive snow.
Furthermore, during the snow season, when conventional tilted modules are often covered by ice and snow, halting power generation, heterojunction vertical modules can leverage their ultra-high bifaciality. This allows them to effectively utilize up to 80% of the reflected light from the snow, achieving efficient double-sided power generation.
Better power generation curve, more gains, less energy storage requirements
The vertical solar system boasts a "double peak" power generation curve, which facilitates offsetting peak power demand, maximizing revenue during high electricity prices, and minimizing power curtailment during low prices. This advantageous profile enables （balcony）PV battery storage systems to function with fewer energy storage battery modules while maintaining the same capacity, effectively meeting grid peak regulation requirements.
Higher Solar Energy Utilization
Approximately 5% of the light striking a solar module is inevitably reflected due to the combined optical properties of the encapsulating glass and the module itself. When installed at an oblique angle, this reflected light escapes into the sky, resulting in wasted energy and potential light pollution. However, vertical solar systems capture some of this reflected light, redirecting it onto nearby plants or other panels for reuse, leading to a higher overall solar energy utilization rate.
Reduced Environmental Noise
The module's coated glass features a porous silica microstructure that can absorb and reflect sound waves, contributing to lower ambient noise levels. Additionally, the vertical design facilitates seamless integration with building structures, further enhancing noise reduction through improved sealing.
Heterojunction (HJT) solar cells have perfectly symmetrical bifacial structural characteristics, supplemented by innovative designs such as professional component frames and glass. Huasheng Himalayan series of vertical products lead the industry with ultra-high bifacial ratios of up to 97%. Such a high bifacial ratio combined with the vertical installation method greatly increases the gain on the back side. According to simulation calculations, the power generation capacity of ultra-high bifacial ratio heterojunction modules is significantly higher than that of conventional tilt-mounted modules.
Heterojunction technology is currently the most efficient photovoltaic cell manufacturing technology. The mass production power of Huasheng G12-132 module exceeds 720W, and its championship power has reached 750.54Wp, with an efficiency of 24.16%, leading the industry.
What are the vertical installation scenarios for heterojunction modules?
Compared with traditional support structures , agricultural photovoltaics using heterojunction vertical components can not only provide power generation income, but also occupy a smaller area. This solution minimizes the impact on animals, plants, agricultural machinery and agricultural production activities. The ultra-high bifacial ratio heterojunction module is perfectly adapted to the German Next2Sun bracket system, and the two parties have reached relevant strategic cooperation on the application of vertical installation scenarios.
PV fences can effectively solve key problems such as solar power generation area restrictions and insufficient power generation, accelerating the adoption of solar energy in areas with limited space, while integrating fencing functions, component aesthetics and power generation economic benefits.
High speed guardrail
Highway PV guardrails can maximize the use of existing resources to produce green energy and only occupy very little additional land, producing clean energy while reducing traffic noise. Considering the ubiquity of highways, the huge market potential of related applications needs to be developed urgently.
PV building integration
In architectural scenarios, vertical components can be used as sound insulation barriers, sunroom walls, solar balconies, building exterior walls, urban landscapes, etc. They can not only realize architectural functions, but also contribute to green energy and add a sense of technological beauty to modern life.
