Jiangyin Free Technology shines at the 2025 SOLAR & STORAGE LIVE AFRICA Photovoltaic Exhibition in South Africa——Leading Africa's Energy Transition with New Photovoltaic Material Technology

Exhibition Highlights: China-Africa Collaboration Drives New Energy Development 

From March 25 to 27, 2025, SOLAR & STORAGE LIVE AFRICA, the largest renewable energy exhibition in Africa, concluded successfully at the Johannesburg Expo Centre , South Africa. The event attracted over 650 exhibitors from 40 countries, focusing on solar power generation, energy storage technologies and clean energy innovations. It aimed to advance Africa’s goal of achieving "reliable, sustainable, and affordable" universal electricity access through industry exchanges and technological showcases.

As a key exhibitor, Jiangyin Free Technology Co., LTD. (hereinafter referred to as Free) as the main force of the exhibition, with the latest technological achievements. Among them, the Free’s polyurethane composite photovoltaic frame/bracket integrated power station system became the focus of the exhibition.

Polyurethane Composite Frame/Bracket: Dual Breakthroughs in Performance and Sustainability 

At the exhibition, Free showcased its integrated photovoltaic frame/bracket system based on polyurethane composite materials, highlighting the following core advantages:

1.Lightweight, High Strength, and Weather Resistance: The polyurethane composite material reduces weight by 25% compared to aluminum alloy and by 75% compared to steel, while the tensile strength is over four times higher than the aluminum. It also withstands harsh environments such as high humidity and salt spray, making it ideal for photovoltaic power stations in Africa’s coastal and desert regions.

2.Cost Reduction and Efficiency Improvement: Compared to traditional aluminum alloy frames, the polyurethane composite frame reduces unit costs by approximately 20% and cuts carbon emissions during production by 90%, aligning with Africa’s demand for both economic viability and environmental sustainability.

3.Insulation and Anti-PID Performance: The material’s high volume resistivity (up to 1×10¹⁴ Ω·m) effectively mitigates potential-induced degradation (PID), enhancing module efficiency. It also eliminates the need for grounding, simplifying installation.

4.Customization and Rapid Production: Utilizing pultrusion molding technology, the system enables fast manufacturing and supports diverse color designs to meet various application scenarios.

Summary and Outlook: Co-Creating Africa’s Green Future with Innovative Technology

The success of this exhibition underscores Free’s integration into the global clean energy supply chain. With its performance and cost advantages, the polyurethane composite frame/bracket system is poised to replace traditional solutions, becoming the preferred choice for distributed photovoltaics, offshore power stations, and other applications in Africa.

Looking ahead, Free will focus on:

Enhancing Recycling Systems: Improving composite material recycling technologies to align with full lifecycle management of photovoltaic modules and reduce environmental impact.

Expanding Application Scenarios: Developing coatings and structural designs with higher weather resistance for Africa’s arid and sandy environments.

Deepening China-Africa Collaboration: Supporting Africa’s independent new energy industry chain through technical training and joint R&D.
