Heterojunction Module + Vertical Installation: Releasing Solar Potential

Vertical installation , a revolutionary approach that involves mounting photovoltaic modules at a 90° angle, not only optimizes the use of solar energy, but also efficiently saves land. This innovative method opens up new possibilities for the seamless integration of photovoltaic plants with agricultural activities and much more, redefining the landscape of solar applications.

1. Better use of space

Vertical photovoltaic modules maximize space utilization with a minimum designed area. This approach does not alter the land, making it ideal for agricultural areas and ensuring optimal solar energy generation.

2. Easier maintenance

By preventing the accumulation of dust and dirt, vertical installation reduces the need for frequent cleaning, minimizing losses in energy generation and increasing system reliability. Additionally, it eliminates snow cover, mitigating the risks associated with excess snow.

3. Better power curve, greater return

The power generation curve of the vertical photovoltaic system has a “double peak” characteristic, allowing staggered power supply and optimizing electricity revenue during peak market periods. This results in reduced dependence on energy storage for grid peak reduction in photovoltaic storage systems.

4. Greater use of solar energy

Vertically installed modules redirect reflected solar energy to nearby plants or other photovoltaic arrays, reducing energy waste compared to modules installed at an angle of inclination.

5. Reduced environmental noise

The coated glass used in photovoltaic modules has a porous silica microstructure, which can absorb part of the sound waves, thus reducing environmental noise. Meanwhile, vertical installation improves integration with building structures, providing better closure options.

Ⅱ. Why heterojunction?

Heterojunction solar technology (HJT) features a perfectly symmetrical double-sided structure, complemented by innovative designs such as module frames and glass. Huasun's next-generation HJT modules can achieve ultra-high bifaciality of up to 97%, an unprecedented level in the industry. The combination of high bifaciality and vertical installation contributes to significant revenue increases. HJT modules with ultra-high bifaciality demonstrate energy yield performance comparable to that of commonly tilted installations.

Currently, the champion power of HUASUN HJT module with common G12 size reaches 750.54W, with an efficiency of 24.16%, leading the industry.

Ⅲ. What are the scenarios?

1. Photovoltaic/agrivoltaic agriculture

Huasun's ultra-high bifaciality modules, combined with Next2Sun's innovative assembly system, offer electricity generation benefits with minimal land occupation, minimizing disruptions to agricultural activities.

2. Solar Fence

The solar fence perfectly integrates fence functions, technological aesthetics and economic benefits.

3. Photovoltaic highway guardrails

Maximizing existing resources for green energy production, photovoltaic road guardrails act as renewable energy sources and noise barriers, offering unlimited potential.

4. Airport areas

In contrast to conventional ground-mounted systems, minimal land use can avoid a negative impact on precipitation distribution and vegetation.

5. Building Integrated Photovoltaic (BIPV)

In construction scenarios, vertical modules serve as acoustic barriers, canopies, photovoltaic balconies, building facades and urban landscapes, combining functionality with green energy and technological aesthetics.
