Explore MachineBrazil has emerged as one of the fastest-growing solar energy markets globally. Governed by Law 14.300 (Marco Legal da Geração Distribuída) and the rising demand for utility-scale developments in the Northeast (Nordeste region), local PV module manufacturers are increasingly shifting from raw material imports to localized manufacturing. This industrial transition requires high-performance, automated, and reliable extrusion machinery to produce encapsulation films (EVA/POE) and structural components like solar frames.
Customs policies, Mercosur import duties, and the BNDES FINAME certification framework incentivize domestic assembly of PV modules. Establishing in-country solar extrusion plants allows manufacturers to qualify for localized financing lines while avoiding volatile international supply chains.
By establishing domestic extrusion capacity, local companies can achieve continuous production cycles, lowering overall module fabrication costs by up to 18%.
Multilayer EPE film (EVA/POE/EVA) extrusion has become the preferred technological pathway, as it balances the raw material cost savings of EVA with the critical moisture barrier performance of POE.
Understanding the molecular-level processing of EVA and POE to achieve maximum module lifespan (25+ Years).
High-speed extrusion lines require optimized cooling and tension-free winding. Our advanced web paths keep thermal shrinkage below 1.5% in machine direction (MD) and transverse direction (TD), protecting PV cells from stress micro-cracks during lamination.
EVA and POE resin extrusion is extremely temperature-sensitive. Excessive heat triggers premature cross-linking in the extruder barrel, creating gel spots. Our smart control systems maintain melt temperature deviations under ±1°C.
We utilize specialized feedblocks and multi-manifold dies to execute complex A/B/A structured EPE co-extrusion. This maintains high output rates (up to 35m/min) while ensuring consistent layer thickness control within ±2%.
| Parameter | EVA Film Extrusion | POE Film Extrusion | EPE Co-Extrusion |

| PID Resistance Capability | Moderate (Susceptible over time) | Excellent (Ideal for N-Type Panels) | High (Best balance of cost/protection) |
| Production Cost Ratio | Baseline (100%) | High (~130%) | Moderate-High (~115%) |

Explore EquipmentCommon questions from Brazilian manufacturing facilities considering localized film production.
POE (Polyolefin Elastomer) has a water vapor transmission rate (WVTR) that is nearly 20 times lower than EVA. This property makes it highly effective at preventing Potential Induced Degradation (PID), which is particularly beneficial for high-efficiency N-type solar modules (TOPCon/HJT) operating in humid environments like Brazil's coastal regions.
Yes, GWELL extrusion lines feature flexible configurations that allow for the processing of both EVA and POE resins. By adjusting the screw temperature profile and feeding parameters, manufacturers can switch between standard EVA, pure POE, or co-extruded EPE films on the same base production system.
Polyurethane composite frames offer excellent corrosion resistance, high tensile strength, and low thermal conductivity. For solar installations in seaside regions with high salinity and humidity, polyurethane frames are highly resistant to chemical corrosion and reduce the risk of structural degradation.
We use automated tension-relief winding systems paired with precision multi-roll cooling stacks. Controlling film tension and cooling rates ensures that thermal shrinkage remains below 1.5% at high winding speeds, which prevents cell shifting during the laminating stage.
