1. Confirm the Material Type: EVA or POE?

Different solar module applications require different film materials. EVA offers excellent transparency and processability, ideal for general PV modules, while POE is preferred in hot and humid environments due to its lower water vapor permeability and superior aging resistance. When choosing a line, make sure it supports multiple materials (EVA/POE/EPE) with flexible switching of dies or process settings.

2. Focus on Output Capacity and Operational Stability

A high-efficiency extrusion line must deliver stable, continuous operation and meet production capacity needs. For example, GWELL's EVA/POE film extrusion lines offer 300–750kg/h capacity, suitable for mid- to large-scale solar panel manufacturers.

3. Choose the Right Film Layer Structure

Projects may require single-layer, double-layer, or triple-layer co-extruded films. A line that supports multilayer co-extrusion can meet current needs and provide flexibility for future product upgrades.

4. Control System and Thickness Detection

High-performance solar films require excellent thickness uniformity and optical clarity. Therefore, it's essential to choose a machine equipped with automatic thickness scanning, precision tension control, and an intelligent PLC operating system.

5. After-Sales Service and Delivery Time

Timely delivery and fast commissioning are critical for solar projects. Choose a supplier with reliable production capacity, experienced installation teams, and remote technical support, as these factors directly affect project progress.

Conclusion:

When choosing an EVA/POE solar film extrusion line, price is just one factor. Material compatibility, production efficiency, film structure flexibility, control systems, and after-sales support must all be considered for a truly high-yield, high-quality, low-defect solar module manufacturing outcome.
