Technical SpecificationsDominica, widely recognized as the "Nature Island of the Caribbean," is steering toward absolute climatic resilience, aiming to build a 100% renewable energy matrix. Under the framework of the Climate Resilience Act, the transition to decentralized solar microgrids is accelerating. However, Caribbean solar installations face a critical vulnerability: marine-induced atmospheric corrosion, high UV radiation index, and Category 5 hurricane wind loads.
Traditional solar structures and encapsulation layers degrade prematurely under tropical marine environments. Sourcing solar encapsulation films and composite structures that offer maximum moisture resistance and mechanical toughness is paramount. Our high-performance solar extrusion lines play a key role in manufacturing raw materials optimized for this exact environment.
To prevent Delamination and Potential Induced Degradation (PID) in tropical regions, solar panels require highly advanced POE (Polyolefin Elastomer) and PVB interlayers. Our extrusion machinery achieves continuous thickness control within ±1%, ensuring that the barrier properties of the manufactured films meet strict international IEC standards.
Why Tier-1 solar panel manufacturers choose China Gwell's Industry 4.0 extrusion lines for international deployment.
Equipped with computerized closed-loop gravimetric dosing systems and automatic T-dies. The integration of IoT technology allows real-time diagnostics, remote maintenance, and precision temperature management (accuracy within ±0.1°C).
Our lines process advanced PVB, EVA, and POE formulations with optimized screw designs that prevent polymer pre-crosslinking. This ensures the film exhibits near-zero shrinkage rates during final lamination by global PV module assemblers.
Conforming fully to CE, ISO9001, and UL quality directives. Gwell provides comprehensive turnkey solutions from initial raw material blending formulations to commissioning, training, and life-cycle supply support.
In coastal microgrids like those in Dominica (Roseau, Portsmouth), standard PV module encapsulation fails due to moisture ingress, causing rapid potential induced degradation. POE (Polyolefin Elastomer) films produced by Gwell's custom extrusion lines boast a Water Vapor Transmission Rate (WVTR) that is 10 to 20 times lower than traditional EVA. This drastically extends the life cycle of photovoltaic setups operating under highly corrosive atmospheric conditions.

Detailed insights from our technical growth directors regarding polymer film extrusion for marine microgrids.
Dominica features high humidity and coastal salt-mist. Standard EVA film experiences moisture decomposition, yielding acetic acid which corrodes the silver grid lines on the PV cells. Polyolefin Elastomer (POE) film has a water vapor transmission rate that is significantly lower and maintains excellent chemical stability, preventing PID (Potential Induced Degradation).
Our lines utilize automated beta-gauge or laser-gauge feedback loops integrated with a dynamic flex-lip automatic T-die. If any thickness variation is detected, the control PLC instantly adjusts the thermal bolt zone temperatures to maintain film thickness consistency within ±1% across the entire width.
Polyurethane structural composites exhibit excellent corrosion resistance, making them immune to the galvanic corrosion that degrades aluminum frames in coastal locations. Additionally, polyurethane is non-conductive, which reduces grounding complexity and improves safety in hurricane-prone zones.
We utilize custom low-shear barrier screws designed for low melt temperatures. This prevents hotspots and ensures that cross-linking catalysts in EVA and POE do not react inside the barrel or T-die, preventing gels and preserving optical qualities.
We provide full layout and installation diagrams before delivery. When the machine arrives, Gwell engineers assist with structural assembly, process tuning, and raw material formulation, alongside local team training, either on-site or via remote AR diagnostic networks.
Our industrial production lines output between 600 kg/h and 1,200 kg/h depending on width configuration and film thickness, ensuring cost-efficient manufacturing of high-demand encapsulation components.
