Central African Republic 25MW photovoltaic plus energy storage integrated project - stable and green off-grid energy system

The Central African Republic is rich in sunlight resources, but its power grid infrastructure is weak, which seriously affects economic development and people's livelihood electricity consumption. The 25MW photovoltaic + energy storage integrated project we designed for the country aims to build a highly reliable, intelligently controlled clean energy power system to provide 24-hour stable power supply for mining areas, towns and key facilities.

1. Project Core Challenges and Solutions

Challenge 1: The power grid is fragile and cannot support large-scale renewable energy grid connection

✅ Solution:

Photovoltaic storage off-grid/microgrid mode: Photovoltaic power generation is used to supply the load first, and excess electricity is stored in the energy storage system, with diesel generators as backup.

Intelligent dispatching system: dynamically optimizes charging and discharging strategies, reducing diesel consumption by more than 30%.

Challenge ② High temperature, high humidity, and dust affect equipment life

✅ Solution:

Photovoltaic modules: Double-sided power generation is used to adapt to high temperature and high humidity environments, with an annual attenuation rate of <0.5%.

Energy storage system: The temperature control system ensures stable operation at -20℃~50℃, and the service life is ≥6000 cycles.

Box-type substation: IP54 protection level, dust-proof and moisture-proof design, key components are made of stainless steel.

Challenge 3: Insufficient local operation and maintenance capabilities

✅ Solution:

Remote monitoring platform: real-time monitoring of power generation, battery health status, grid frequency, etc., supporting PC/mobile terminal viewing.

Local team training: Provide French technical manuals + on-site operation training to ensure basic operation and maintenance autonomy.

Challenge ④ Tight project cycle and fast delivery required

✅ Solution:

Pre-installed integrated solution: modular design of photovoltaic brackets, inverters, and energy storage systems to reduce on-site installation time.

Cooperative warehousing shortens equipment transportation cycle.

3. Technical highlights

High reliability design

The energy storage system supports seamless switching (<10ms), ensuring that critical loads (such as hospitals and communication base stations) are not disconnected from power supply.

The photovoltaic inverter has a PID repair function, which automatically restores component performance at night and extends its life.

Localization Adaptation

It complies with the Central African Republic SEL (Société d'Énergie du Liban) grid-connected standards and can be switched to off-grid mode.

Anti-animal gnawing design: cable sleeve + box body anti-rat board, adapt to the African wild environment.

Intelligent Operation and Maintenance

Digital twin system: 3D visualization of power station operation status and automatic location of abnormalities

Supports multi-energy synergy of "photovoltaic + energy storage + diesel engine" to maximize the utilization rate of clean energy.
