400 kW Hybrid Solar Power System with 800 kWh Battery Storage Powers 138 Households in Chad

The Sogoya Village Solar Power Project in Chad is a government project designed to address long-term electricity shortages and reduce dependence on expensive diesel generators.

Commissioned in January 2025, the project combines a 400 kW power conversion system, an 800 kWh battery energy storage system, and a 435 kWp solar photovoltaic array. The hybrid off-grid system serves 138 households, with reported daily electricity generation of 2,200 kWh and annual diesel displacement of 240,000 liters.

Designed for hot, dusty environmental conditions, the system combines solar generation, battery storage, and backup diesel generators to provide a more reliable and sustainable electricity supply for the village.

The Challenge: Addressing Long-Term Power Shortages

Sogoya Village faced persistent electricity shortages, while conventional diesel generation was costly and difficult to sustain.

The project required a dependable power supply that could serve local households while reducing reliance on diesel fuel. Operating conditions also presented practical challenges, including high temperatures and dust.

A suitable solution needed to combine renewable power generation, energy storage, environmental adaptability, and backup power to support reliable village electrification.

Our Solution: An Integrated Solar and Battery Power System

1. Heat-Resistant and Dustproof Design

The system was designed to operate in hot, dusty conditions, making it suitable for the demanding environment of Chad and other off-grid locations with similar climates.

2. Independent Off-Grid Operation

The solar PV array and battery energy storage system form an integrated power supply that can operate independently of the utility grid. Solar electricity is generated during the day, while battery storage helps balance power supply and demand.

3. Integration with Backup Diesel Generators

The hybrid system is integrated with backup diesel generators to support electricity availability when solar and battery power alone are insufficient. The switching design helps maintain continuity of power supply.

4. Integrated Inverter and Battery Cabinets

The system uses four integrated inverter-battery cabinets, each rated at 100 kW and 200 kWh. Together, they provide 400 kW of power conversion capacity and 800 kWh of battery storage.

This integrated configuration brings the power conversion and energy storage equipment together in a coordinated system.

Project Results: Measurable Benefits for Village Electrification

The Sogoya project demonstrates how a hybrid solar power system can support rural electrification and reduce dependence on diesel generation.

• 138 households served: Extending access to electricity for village residents.

• 2,200 kWh of daily electricity generation: Providing a substantial renewable electricity supply.

• 240,000 liters of diesel displaced annually: Reducing dependence on conventional fuel-based generation.

• 800 kWh of battery storage: Helping balance solar generation and electricity demand.

• Off-grid operation with diesel backup: Supporting power availability when renewable generation and stored energy are insufficient.

By combining solar PV, battery storage, and backup generation, the project provides a practical approach to improving electricity access in areas affected by unreliable or limited grid infrastructure.

Local Service and After-Sales Support in Chad

Reliable service is essential for village solar power projects, particularly when installations are located far from major service centers.

Our local support arrangements in Chad include an engineer based in the country and a local service partner to support the project throughout its lifecycle.

The service commitment includes:

• Pre-sales site assessment: On-site surveys before order confirmation.

• Installation guidance: Technical assistance during system installation and commissioning.

• After-sales support: A stated response time of within 24 hours.

• Warranty coverage: Five-year warranties for the battery system and inverters.

• Locally stocked spare parts: Supporting maintenance and reducing potential service delays.

• Remote monitoring: EMS-based monitoring for system operation and troubleshooting.

These arrangements are intended to provide customers with more accessible technical support and improve long-term system maintainability.
