Indonesia's fishing fleet numbers in the tens of thousands, and almost all of them run on diesel generators that burn fuel around the clock — powering navigation electronics, lighting, refrigeration, and communication systems. The fuel cost is the single largest operating expense for fishing vessel operators.
BATREKU has developed a purpose-built solar + storage solution for fishing vessels that delivers measurable, rapid ROI while dramatically improving the onboard working environment. Here's the complete breakdown of the system, its economics, and why it matters for Indonesia's maritime communities.
The Numbers That Matter
System Architecture
The fishing boat solar+storage system integrates four core components designed to work in harmony in the harsh marine environment:
⚡ System Architecture Overview
Component Details
-
Ship-Top Photovoltaic Panels High-efficiency monocrystalline panels mounted on the vessel's roof/canopy structure. Marine-grade anti-corrosion coating, designed to withstand salt spray, UV exposure, and tropical downpours. Typical configuration: 1-3 kWp depending on vessel size and available roof area.
-
LFP Battery Storage System BATREKU's AIO BESS modules (16kWh per unit, expandable 1-6 units in parallel) provide the energy buffer. LFP chemistry ensures safety in marine environments — higher thermal runaway threshold, no toxic gas emission. Deep-cycle rated for daily charge/discharge operations.
-
Intelligent Energy Management System (EMS) Smart controller manages solar charging, battery storage, and load distribution. Automatically prioritizes solar power during daylight, switches to battery at night, and optimizes charge/discharge cycles for maximum battery lifespan. Remote monitoring via mobile app.
-
Marine-Grade Protection (IP65) All system components carry IP65 waterproof rating — fully protected against water jets from any direction. Specifically designed for tropical marine environments with high humidity, salt corrosion, and extreme temperature variations.
Economic Analysis: The Case for Solar on Ships
The economics are compelling. Here's the detailed savings breakdown for a typical mid-sized fishing vessel:
Daily Operating Savings
| Item | Before (Diesel Only) | After (Solar+Storage) | Daily Savings |
|---|---|---|---|
| Diesel consumption (electronics/lights) | ~55 liters/day | ~15 liters/day | ≥40 liters |
| Daily fuel cost (at Rp25,000/L) | Rp1,375,000 | Rp375,000 | Rp1,000,000 |
Investment Recovery Timeline
After the 1.6-year payback period, every subsequent day of operation generates pure savings. Over a 25-year system lifetime, the cumulative savings reach Rp645 million (approximately 6.45M) — a transformational amount for fishing vessel operators and fishing village economies.
Beyond Economics: Quality of Life Improvements
The financial case is strong, but the non-monetary benefits are equally important:
Battery storage eliminates the constant generator noise, dramatically improving crew comfort and sleep quality during overnight operations
Eliminating 40+ liters of daily diesel burn per vessel means significant CO₂ reduction — critical as global fishing industry faces increasing environmental scrutiny
Reduced dependence on diesel fuel supply chains means vessels can operate longer at sea without refueling trips, increasing productive fishing time
Real-time system status via mobile app — battery level, solar generation, load consumption — gives operators complete visibility and control
BATREKU Product Configuration for Fishing Vessels
| Component | Specification | Notes |
|---|---|---|

| Battery Storage | 16-96 kWh (1-6× AIO BESS modules) | LFP chemistry, IP65, deep-cycle rated |
| Inverter/Charger | Hybrid inverter with MPPT | Built-in solar charge controller |
| EMS Controller | Smart energy management system | Auto charge/discharge, mobile app monitoring |
| Protection Rating | IP65 (all components) | Waterproof, dustproof, salt-spray resistant |
| Operating Temperature | -20°C to +60°C | Tropical marine optimized |
| Design Life | 25 years (panels) / 10+ years (battery) | Low degradation LFP cells |
Target Market: Indonesia's Fishing Fleet
Indonesia is the world's second-largest fishing nation by volume, with an estimated fleet of over 640,000 vessels. The vast majority are small to medium-sized vessels that operate within Indonesia's 5.8 million km² maritime territory.
Even capturing a small fraction of Indonesia's fishing fleet represents a multi-thousand-unit market. Each vessel saves 40+ liters of diesel daily — at current fuel prices, that's over Rp360 million in annual savings per boat.
When combined with the village-level solar deployment plan (80,000 villages), fishing boat solar+storage becomes a natural extension of BATREKU's existing village electrification strategy. Many fishing villages along Indonesia's coastline can benefit from both on-shore village solar systems and on-vessel energy solutions.
Why BATREKU Is Uniquely Qualified
-
Complete Integrated Solution BATREKU manufactures the entire system — panels, batteries, inverters, EMS — ensuring perfect compatibility and single-point accountability. No multi-vendor integration headaches.
-
Marine-Proven Products All components carry IP65+ rating and are tested for tropical marine conditions. Salt spray resistance, high humidity tolerance, and wide temperature range operation are standard — not add-ons.
-
Local Manufacturing + After-Sales Indonesian factory means local warranty service, spare parts availability, and technical support. No waiting weeks for replacements from overseas — BATREKU's 100+ installation team handles it.
-
Scalable Configuration From small fishing boats (16kWh single module) to larger ocean-going vessels (96kWh, 6 modules in parallel), the modular AIO BESS system scales to match any vessel's energy needs and budget.
A fishing boat solar+storage system from BATREKU pays for itself in just 1.6 years, then continues generating pure savings for decades. Over 25 years, a single vessel saves Rp645 million — while eliminating 40+ liters of daily diesel consumption, reducing noise, improving crew comfort, and cutting emissions.
For Indonesia's fishing communities, this isn't just a technology upgrade — it's an economic transformation. And for BATREKU, it represents another natural market extension of its core solar+storage manufacturing capability, perfectly aligned with the national village electrification and green energy transition agenda.
