High-precision automated equipment engineered for climate resilience, maximum uptime, and seamless integration into East Java's expanding clean energy production hubs.
Strategic positioning, maritime infrastructure, and regulatory mandates are establishing Surabaya as the primary hub for solar equipment deployment and local panel assembly across Southeastern Asia.
As the capital of East Java and Indonesia’s second-largest economic powerhouse, Surabaya serves as the strategic nexus for manufacturing, international maritime commerce, and heavy industrial output. With proximity to major industrial zones such as the Rungkut Industrial Estate (SIER), Krian Industrial Corridor, and the massive JIIPE (Java Integrated Industrial and Ports Estate) in Manyar, Gresik, Surabaya is uniquely positioned to lead Indonesia’s renewable energy expansion.
Indonesia’s updated National Electricity General Plan (RUPTL) and Ministry of Energy and Mineral Resources (EMR) directives mandate a steep ramp-up in solar power capacity, aiming for over 5.3 GW of installed solar PV by 2030. To achieve these aggressive decarbonization milestones, local energy developers and international joint ventures are shifting away from fully imported modules toward domestic assembly lines operating in Surabaya.
By establishing PV module production factories in East Java, solar manufacturers leverage Tanjung Perak Port for seamless raw material import (silicon wafers, tempered glass, EVA/POE encapsulants, junction boxes) while maintaining rapid logistics routes to neighboring provinces and island microgrid projects across East Indonesia.
To bid on state-owned utility (PLN) projects, solar rooftop initiatives, and commercial IPP contracts in East Java, module assemblers must comply with strict Ministry of Industry TKDN ratings. Equipment precision directly influences how effectively local factories can integrate Indonesian-made glass, aluminum frames, and junction boxes without sacrificing module efficiency.
| Compliance Tier | Target Market Segment in Surabaya / Indonesia | Minimum TKDN Requirement | Recommended Manufacturing Line Configuration |
|---|---|---|---|
| Tier 1 PLN Utility Scale | Grid-tied utility parks, floating solar (Pembangkit Listrik Terapung) | ≥ 40.0% to 60.0% | Full Auto 100MW–500MW Line with 0BB Stringing & Auto Framing |
| C&I Commercial Rooftop | Factories in SIER, Gresik, & Pasuruan Industrial Estates | ≥ 40.0% | Semi-Auto or Full-Auto 50MW–100MW High-Efficiency TOPCon Line |
| Off-Grid & Island Microgrids | East Java archipelagic islands (Madura, Bawean, Kangean) | ≥ 35.0% | Flexible 10MW–30MW Multi-Grid Stringer & Custom Laminator Line |
The solar manufacturing sector is experiencing a rapid technological evolution. Capital expenditures in Surabaya must account for next-generation cell architecture compatibility and climate-adapted encapsulation tech.
Legacy P-type PERC cell lines are giving way to N-type TOPCon (Tunnel Oxide Passivated Contact) and Heterojunction (HJT) cells with module efficiencies exceeding 23.5%. ApexSolar machinery supports sub-100µm wafer handling, ultra-low thermal stress stringing, and precise temperature gradient controls required for delicate N-type wafers.
Moving from 9BB/12BB to Zero Busbar (0BB) and Super Multi-Busbar (SMBB) micro-soldering reduces silver paste consumption by up to 30% while boosting optical acceptance. Our high-speed tabber stringer systems utilize non-contact infrared soldering to eliminate micro-cracking and hot-spot risks.
Surabaya’s maritime atmosphere features high relative humidity (averaging 75%-85%) and coastal air salinity. Equipment must support POE (Polyolefin Elastomer) and double-glass vacuum encapsulation cycles to eliminate Potential Induced Degradation (PID) and water-vapor ingress over 30-year operational lifetimes.
Specialized automation machinery engineered to deliver maximum yield, zero delamination, and precise electrical interconnection for factories across Surabaya and East Java.
As global PV manufacturing decentralizes to serve regional markets like East Java, partner manufacturers rely heavily on China's mature upstream equipment ecosystems. Suzhou GeoSyn Solar Co., Ltd. (operating under its premier brand ApexSolar) bridges world-class Chinese automation technology with localized operational requirements in Surabaya.
By leveraging integrated Industry 4.0 smart manufacturing architectures—including MES (Manufacturing Execution System) monitoring, SCADA centralized control, and inline AI machine vision—ApexSolar turnkey lines drastically lower operational expenditures (OPEX) while ensuring zero-defect outputs for high-volume panel assembly.
From heavy commercial rooftops in industrial parks to isolated island microgrids, our manufacturing lines produce modules specifically tuned to East Java's geographic challenges.
Factories in East Java operate under severe thermal cycling and salt-laden corrosive ambient air. ApexSolar vacuum laminators integrate dual-vacuum chamber technology and pin-lifting heating profiles. This ensures complete cross-linking (>85%) of EVA/POE laminates, preventing bubble formation, moisture delamination, and frame corrosion over 25+ years of rooftop exposure.
Electrifying surrounding islands (such as Madura, Bawean, and Kangean Archipelago) demands lightweight, highly durable 36-cell and 60-cell customized solar panels integrated with battery storage. Our semi-automated 10MW–30MW lines provide quick product pattern changeover, enabling manufacturers in Surabaya to quickly switch between glass-backsheet and glass-glass configurations.
Modern Indonesian industrial clients require combined PV module generation and ESS (Energy Storage System) battery buffering. Our integrated laser welding and cell pack assembly machinery allow plant operators in Surabaya to manufacture both high-efficiency solar panels and complementary lithium battery packs within the same industrial facility.
