The most powerful business opportunities often arise at the intersection of two distinct industries. In Indonesia, a global powerhouse in aquaculture, this very intersection is creating a compelling case for investment.
The country’s vast network of shrimp farms and fisheries faces a significant operational challenge: high and rising energy costs, which can account for up to 30% of total expenditures. While solar power presents an obvious solution, a critical environmental factor—corrosive salt mist—renders standard solar modules unreliable and short-lived in the coastal locations where they are needed most.
This article outlines a feasibility framework for a specialized solar module factory in Indonesia, designed specifically to address this niche. The focus is on producing high-performance, salt-mist resistant modules tailored to the unique demands of the aquaculture industry, transforming a critical vulnerability into a strategic advantage.
The Convergence of Solar Energy and Aquaculture
Indonesia is the world’s second-largest aquaculture producer, a vital component of its economy and food security. The industry’s operations, particularly its aeration and water pumping systems, are energy-intensive and run 24/7. This reliance on a stable and affordable power supply makes the sector highly vulnerable to electricity price fluctuations and grid instability.
Agrivoltaics—the dual use of land for both agriculture (or aquaculture) and solar power generation—offers a powerful solution. By installing solar arrays over shrimp ponds or reservoirs, operators can generate their own clean electricity, reduce operational costs, and even lower water evaporation.
However, a conventional approach is destined for failure. Coastal air is laden with salt and moisture, an aggressive combination that accelerates the degradation of typical solar panels. The result is premature system failure, lost revenue, and a poor return on investment, creating deep-seated skepticism about solar technology in these environments.
Why Standard Solar Modules Are Unsuitable for Coastal Environments
The challenge is not solar energy itself, but the durability of the equipment. Standard photovoltaic (PV) modules, while effective in many climates, are not engineered to withstand the chronic assault of salt mist. This constant exposure leads to several distinct modes of failure:
-
Corrosion of Frames and Junction Boxes: The aluminum frames and electrical connections are the first to suffer, compromising the module’s structural integrity and electrical safety.
-
Delamination: Moisture and salt can penetrate the module’s layers, causing the encapsulant to separate from the glass. This ingress of moisture severely degrades the solar cells within.
-
Potential-Induced Degradation (PID): High humidity and sodium ions from salt create electrical leakage paths, dramatically reducing the module’s power output over time.
For an investor, this means a solar asset that should last 25 years might fail in less than a decade, completely undermining the project’s financial viability.
The Technical Solution: Bifacial DESERT+ Modules
Success in this market requires a specialized product. The solution lies in combining two advanced PV technologies: bifacial design and enhanced corrosion resistance.
The Advantage of Bifacial Technology
Bifacial modules capture sunlight on both sides. When installed over water, they not only absorb direct sunlight from above but also capture light reflected off the water’s surface (known as albedo). This can increase energy yield by 10–25% compared to monofacial modules, making them exceptionally efficient for aquaculture applications.
The Necessity of DESERT+ Construction
Technologies like the J.v.G. DESERT+ module are engineered specifically for these harsh environments. These modules typically feature:
-
Glass-Glass Encapsulation: Replacing the standard plastic backsheet with a second layer of glass creates a hermetic seal, preventing moisture and salt ingress.
-
Corrosion-Resistant Materials: Junction boxes, sealants, and frames are made from materials that can withstand long-term exposure to saline conditions.
-
Certified Durability: These modules undergo rigorous testing, such as the Salt Mist Corrosion Test (IEC 61701, Severity Level 6), to certify their performance in coastal and offshore environments.
A local factory producing these specialized modules would have a distinct and defensible market advantage over importers of standard panels.
Framework for a Feasibility Study
Any serious industrial project begins with a thorough evaluation. For an entrepreneur entering this space, the feasibility study should be built on three core pillars: market strategy, technical implementation, and financial modeling.
1. Market Analysis and Strategy
The primary target market is large-scale Indonesian seafood conglomerates and aquaculture farm operators. The value proposition is not simply selling solar panels but providing a long-term solution to reduce operational energy costs. A go-to-market strategy would involve forming partnerships with these industry leaders, demonstrating the superior lifetime value and reliability of locally produced, salt-mist resistant modules.
2. Technical and Operational Plan
The plan centers on establishing a local manufacturing facility. A modern turnkey solar manufacturing line offers a structured, efficient path to market entry. This approach bundles the necessary machinery, process knowledge, and training, mitigating the technical risks for investors new to the PV industry. Based on J.v.G. turnkey projects, an initial line with a capacity of 20–50 MW can be established with a team of fewer than 30 employees, making it a manageable entry point.
3. Financial Modeling
A comprehensive solar manufacturing business plan is essential. This involves more than just calculating initial capital expenditure. A key focus should be on demonstrating the Total Cost of Ownership (TCO) advantage of specialized modules.
While the initial purchase price of a DESERT+ module may be higher than a standard one, its extended lifespan and sustained performance in a coastal environment result in a far lower cost per kilowatt-hour over the project’s lifetime. Financial analysis, supported by consulting teams like the Thoma family office, can model these long-term returns, creating a compelling financial case for both the factory investor and the end customer.
The analysis of costs to start a solar panel factory must extend beyond machinery to include site preparation, logistics, and initial working capital.
The Strategic Advantage of Local Production
Establishing a local manufacturing facility in Indonesia offers strategic benefits beyond serving a niche market:
-
Supply Chain Resilience: Local production reduces reliance on imports, protecting against shipping disruptions and currency fluctuations.
-
Alignment with National Goals: The project supports Indonesia’s goals for renewable energy adoption, food security, and the creation of skilled local employment.
-
Building a Trusted Brand: A local manufacturer can provide superior customer service, technical support, and warranties, building a reputation for quality and reliability that importers cannot match.
Frequently Asked Questions (FAQ)
