Ethylene Vinyl Acetate (EVA) is a copolymer resin used as an encapsulating agent for solar cells. Injected between the glass and the backsheet, it acts as a protective "sandwich" layer, ensuring long-term durability against environmental stress.
CE certification ensures that EVA films meet rigorous European safety, health, and environmental protection requirements, crucial for Tier-1 module manufacturers targeting the EU market.
Our high-quality EVA films offer superior Potential Induced Degradation (PID) resistance, maintaining over 95% of cell efficiency even after 25 years of outdoor exposure.
Suzhou GeoSyn Solar Co., Ltd. is a leading innovator in the solar energy sector, specializing in smart solar power systems for both residential and commercial applications. Headquartered in Suzhou, China, the company has earned a strong reputation for delivering high-performance, reliable, and sustainable solar solutions under its flagship brand, ApexSolar.
The company’s product portfolio includes residential rooftop solar systems, commercial-scale solar installations, energy storage solutions, and advanced solar monitoring platforms. Each system is designed to optimize energy generation, reduce electricity costs, and provide reliable power even in off-grid or hybrid configurations.
For procurement directors and engineers, understanding the chemical properties of EVA film is vital for module longevity. We focus on four key performance pillars:
Light Transmittance
Gel Content Ratio
Peel Strength (Glass)
PID Resistance
Optimal lamination requires a precise "Fast Cure" profile. Our films are engineered to reach a cross-linking degree of 85% within 8-12 minutes at 145°C. This ensures that the EVA creates a hermetic seal around the silicon wafers, preventing moisture ingress (Water Vapor Transmission Rate < 25g/m²·24h).
Based in the Suzhou-Shanghai PV cluster, we have direct access to high-purity VAE resins, reducing lead times and ensuring consistent polymer quality across batches.
China accounts for over 80% of global EVA production capacity. This allows us to offer competitive pricing without compromising on the CE-certified quality required for global projects.
Our labs iterate on "White EVA" for increased reflectivity and "EPE" (EVA-POE-EVA) co-extrusion films for bifacial modules, keeping clients ahead of technology shifts.
The transition to N-type cells (TOPCon, HJT) has redefined encapsulation requirements. Unlike traditional P-type cells, N-type wafers are more sensitive to moisture and acetic acid (a byproduct of EVA degradation).
We provide localized technical data sheets (TDS) and safety data sheets (SDS) in multiple languages (English, Spanish, German, French) to assist with local regulatory filing. Our logistics team handles temperature-controlled shipping to ensure the EVA film arrives at your factory with its chemical properties intact (storage at < 30°C and < 60% humidity).
Committed to advancing renewable energy adoption worldwide, Suzhou GeoSyn Solar Co., Ltd. continues to expand its global footprint, offering innovative, intelligent, and eco-friendly solar power systems that empower communities, businesses, and homes to achieve energy independence while reducing environmental impact.
In addition to product innovation, the company emphasizes sustainability, quality control, and rigorous research and development. Suzhou GeoSyn Solar collaborates closely with architects, engineers, and municipalities to deliver tailored solutions that address unique site requirements and maximize energy efficiency.
