An entrepreneur considering a new venture in Yemen sees a landscape increasingly dotted with solar panels on rooftops, powering homes, businesses, and critical infrastructure. The demand is undeniable, yet it raises a fundamental question: how can anyone operate a manufacturing plant that requires stable, continuous power in a country where the national grid is largely non-operational?
This paradox—needing reliable energy to produce energy solutions—is often perceived as an insurmountable barrier. However, the solution lies within the challenge itself. By designing a solar module factory to power its own operations, an investor can turn a significant regional liability into a powerful strategic advantage. This article outlines the technical and financial logic for establishing such a factory in Yemen using an off-grid or hybrid energy system.
The Yemeni Energy Paradox: A Challenge and an Opportunity
Understanding the viability of a self-powered factory begins with grasping Yemen’s unique energy landscape, which is defined by two contrasting realities.
Yemen’s energy infrastructure is in a critical state. According to organizations like the World Bank and UNDP, the conflict has left over 90% of the population without access to the public grid. This forces a reliance on expensive, decentralized diesel generators.
Private electricity tariffs can reach as high as 150 YER/kWh (approx. $0.60 USD)—among the most expensive in the world. The result is immense hardship, but also an enormous, sustained demand for more affordable energy alternatives.
At the same time, Yemen has one of the world’s most abundant solar resources. With solar irradiation levels exceeding 2,500 kWh/m² annually, the potential for photovoltaic energy generation is vast. This untapped resource is the key to solving the energy paradox, not just for the country, but for the factory itself.
The Self-Sufficient Factory: A Feasible and Resilient Model
The concept is straightforward: a factory that manufactures solar modules uses a portion of its own output to meet its operational energy needs. This creates a closed-loop system that insulates the business from the volatility of grid failures and the prohibitive cost of diesel fuel.
Based on J.v.G.’s experience with turnkey projects in regions facing similar challenges, this model is more than theoretical—it’s a practical blueprint for operational resilience. By integrating an independent power plant into the factory design from the start, an investor builds a more robust and cost-predictable business.
Designing the Power System for a Solar Factory
A factory’s power system must be engineered for reliability, particularly for sensitive machinery like laminators and stringers that require uninterrupted operation. A hybrid approach, which balances performance with cost, is often the most effective solution.

The Solar PV Array
The primary power source is a dedicated photovoltaic (PV) array, typically installed on the factory roof or adjacent land. A key advantage is the ability to use modules produced on-site for this array, significantly reducing the power plant’s capital cost. For a typical 20–50 MW solar factory, a 1–2 MW array is generally sufficient to cover the bulk of its daytime energy consumption.
Battery Energy Storage Systems (BESS)
A Battery Energy Storage System is essential for ensuring 24/7 power stability. The BESS stores excess solar energy generated during the day and discharges it at night or on cloudy days, providing the seamless, high-quality power that precision manufacturing equipment requires. This eliminates the risk of production losses from power fluctuations.
The Role of Diesel Generators
In a hybrid model, the diesel generator is relegated to a backup role rather than serving as the primary power source. It runs only to cover peak loads that exceed the solar and battery system’s capacity or during extended periods of low solar irradiation. This strategic approach drastically reduces diesel consumption, operational costs, and exposure to fuel price volatility.
Financial and Operational Considerations
For any investor, the financial implications of this model are paramount. While an independent power system requires an upfront investment, it offers substantial long-term returns and strategic benefits.
Initial Investment vs. Long-Term Savings
The capital expenditure for the solar array and BESS must be factored into the overall business plan. However, this cost is weighed against immense operational savings from avoiding grid or private generator tariffs. When electricity can cost upwards of $0.60/kWh, the payback period for an on-site power system accelerates significantly. Understanding the full initial investment required for a solar factory provides a clear picture of how these costs integrate into the total project budget.
Operational Resilience and Predictability
Energy independence is a powerful competitive advantage. A self-powered factory is immune to blackouts, fuel embargoes, and unpredictable price increases that can halt production at competing facilities. This ensures consistent output, reliable order fulfillment, and stable, predictable operational costs—a critical factor for long-term business planning and profitability.
A Case for Local Manufacturing in Yemen
By establishing a self-sufficient solar factory, an entrepreneur does more than build a resilient business. They create a local source for the very technology needed to address Yemen’s systemic energy crisis. The factory becomes part of the national solution, supplying high-quality, locally-made solar modules to a market with deep and urgent demand.
This approach is particularly effective for enterprises focused on small-scale solar panel manufacturing, since the factory and its power system can be scaled precisely to match market demand and available capital, allowing for phased growth.
Frequently Asked Questions (FAQ)
How much land is needed for the factory’s own solar array?
A ground-mounted 1 MW solar PV system typically requires about 1 hectare (10,000 square meters) of land. However, a significant amount of space can be saved by using the factory’s rooftop, which is often large enough for much of the required array.
Can the factory operate entirely without a generator?
Yes, a factory can be designed to run 100% on solar and battery storage. However, this generally requires oversizing the BESS to account for worst-case scenarios (e.g., several consecutive cloudy days), which increases the initial investment. A hybrid system with a small backup generator is often a more capital-efficient solution, providing the same level of reliability at a lower upfront cost.
What are the main challenges of running an off-grid factory?
The primary challenges are the initial capital outlay for the power system and the need for on-site technical expertise to maintain it. These are manageable, however. Proper financial planning is key, and training local staff can handle the necessary maintenance. This is a core component of comprehensively planning and setting up a solar factory.
Conclusion: Turning a Barrier into a Foundation
The absence of a reliable national grid in Yemen, far from being a prohibitive obstacle, makes a clear business case for a new generation of self-sufficient industrial enterprises. For a solar module factory, this synergy is especially potent: the product it creates is the very fuel that secures its operation.
By investing in an independent hybrid power system, an entrepreneur not only ensures the factory’s viability but also builds a model of resilience and cost predictability perfectly adapted to the local economic environment. This strategic approach transforms a fundamental infrastructure challenge into the foundation of a successful and impactful manufacturing business.
