Eritrea Off-Grid Solar+Storage Project Powers Factory in Coastal Region

Reliable Renewable Energy Solution for Remote Industrial Operations

Located in Eritrea’s sun-drenched coastal region, this innovative 250kW/2MWh photovoltaic-storage hybrid system delivers stable, sustainable power to a factory completely disconnected from grid infrastructure. The project successfully addresses the critical challenge of off-grid power supply in remote industrial locations.

“This solar-storage hybrid system has transformed our operations, providing 24/7 clean power where no grid connection exists. The system cut our diesel consumption by 78% while maintaining uninterrupted production – a remarkable achievement in just 65 days from start to finish.”

— Factory Operations Manager, Eritrea

Project Highlights

• 100% off-grid solution: Fully independent power system in absence of utility infrastructure
• Rapid 65-day deployment: From design to full operation in under 10 weeks
• Hybrid system design: Smart integration of solar, storage and backup generation
• Coastal durability: Specialized C5 anti-corrosion protection against salt spray

System Configuration

Core Components

• 250kW photovoltaic array: Maximizes Eritrea’s abundant solar resources (5.8kWh/m²/day)
• 2MWh battery storage: High-voltage battery system for extended autonomy
• Integrated hybrid inverter: Combines PV and storage conversion in single unit
• Backup diesel generator: Ensures reliability during extended low-sun periods

Key Advantages

Built for Harsh Coastal Conditions

Special C5-grade corrosion protection withstands:

• High humidity (85% RH average)
• Salt spray exposure
• Coastal weathering effects

Intelligent Energy Management

Three-layer power assurance:

1. Primary: Solar generation (daytime)
2. Secondary: Battery storage (night/cloudy periods)
3. Tertiary: Diesel backup (extended bad weather)

Rapid Deployment Benefits

• 65-day complete project cycle
• Pre-assembled modular components
• On-site commissioning services
• Minimal factory downtime during installation

Sustainability Impact

• 78% reduction in diesel consumption
• 420 tons annual CO₂ emissions avoided
• 90%+ renewable energy penetration

This Eritrea project demonstrates how innovative solar-storage-diesel hybrid systems can deliver reliable, clean power for industrial operations in even the most remote off-grid locations, while withstanding challenging coastal environmental conditions.
