Advanced solar encapsulation & structural polymer production systems customized for East Java's manufacturing sector.
A Strategic Whitepaper on Photovoltaic Manufacturing Infrastructure, Industrial Expansion, and Local Value-Add (TKDN) Demands.
Surabaya, as the capital of East Java and Indonesia's second-largest economic center, has emerged as a cornerstone of Southeast Asia’s renewable energy and advanced manufacturing boom. Driven by Indonesia's national decarbonization strategy and the Ministry of Energy and Mineral Resources (ESDM) targets to achieve net-zero emissions by 2060, the industrial demand for local solar component manufacturing—specifically high-grade polymer extrusion lines—has hit an unprecedented high. Industrial parks across the Greater Surabaya hub, such as the Rungkut Industrial Estate (SIER) and the proximity of Java Integrated Industrial and Port Estate (JIIPE) in Gresik, are aggressively upgrading their machinery infrastructure to accommodate local photovoltaic module manufacturing lines.
The Indonesian government enforces strict TKDN (Tingkat Komponen Dalam Negeri) regulations, requiring solar power projects to utilize local manufacturing resources. Procurement managers and industrial factory developers in Surabaya require advanced Solar Extrusion Lines capable of processing virgin and recycled polymer resins locally to comply with domestic content quotas without sacrificing optical efficiency or long-term weatherability.
The industrial corridor spanning Surabaya, Gresik, and Sidoarjo is geographically positioned to serve both domestic Indonesian clean energy installations and exports across ASEAN nations. Heavy investments in utility-scale solar farms across East Java and Madura Island necessitate a robust local supply chain of module packaging materials, including Ethylene Vinyl Acetate (EVA), Polyolefin Elastomer (POE), Polyvinyl Butyral (PVB), and composite polyurethane structural frames. Establishing local extrusion capabilities eliminates shipping bottlenecks, cuts logistics costs, and prevents raw polymer degradation caused by humid equatorial transport environments.
As the global solar market shifts from traditional PERC technology to high-efficiency N-type TOPCon (Tunnel Oxide Passivated Contact) and Heterojunction (HJT) cells, standard EVA encapsulation films encounter limitations regarding water vapor transmission rate (WVTR) and Potential Induced Degradation (PID). Factories operating in Surabaya are rapidly adopting multi-layer co-extrusion technology (such as EPE: EVA/POE/EVA co-extrusion lines). This architecture combines the high adhesion performance of EVA with the low water vapor permeability and chemical inertness of POE, giving module producers in East Java a severe competitive advantage in humid tropical climates.
How specialized extrusion technology guarantees long-term durability in high-humidity, marine, and equatorial operating conditions.
Equipped with high-precision internal spiral flow chill rollers to control resin shrinkage to under 2.5%. This minimizes post-lamination cell warping during PV module assembly in tropical conditions.
Multi-component continuous loss-in-weight dosing systems ensure exact proportions of cross-linking agents, UV stabilizers, and antioxidants without thermal premature gelation.
Flexible A/B/C co-extrusion technology enables seamless switching between pure EVA, pure POE, and composite EPE cast films with precise thickness gauge control.
