Based on the data calculated by PVsyst, Nigeria has abundant solar radiation, and the overall level is relatively high. The annual cumulative radiation is about 1250 - 2800 kWh/�? After calculation, the number of power generation hours is about 1025 - 2296 hours. For the photovoltaic modules, 550Wp - 715Wp modules are selected. One photovoltaic container can install 28 modules on one side, with a total of 56 modules installed. The capacity range is 30.8kW - 40.04kW, and the power generation is about 31,600 kWh - 91,900 kWh.
Core Advantages:
- Rapid Deployment: It is the biggest advantage, meeting the needs of emergency power supply, temporary power consumption, and rapid project startup.
- Modularity and Scalability: One container is an independent power generation unit. When a larger capacity is needed, multiple container units can be placed side by side like building blocks. Usually, a monitoring system is also integrated, facilitating remote management, operation, and maintenance.
- Flexibility and Mobility: It can be easily transported to any place where electricity is needed (as long as there are roads or ports). After the project ends or the location changes, it can be quickly disassembled, loaded back into the container, and transferred to the next location for reuse.
- Reduced On - site Construction: Most of the installation work is completed in the factory. Only unfolding and connection are needed on - site, reducing the requirements for on - site construction conditions and labor, and also reducing the environmental impact and risks brought by on - site construction.
This mode is applicable to various scenarios, such as enterprise park production, agricultural greenhouses, expressway service areas, emergency disaster relief, and field construction.
3. Introduction to 215kWh Energy Storage Cabinet
The 215kWh commercial and industrial energy storage system consists of 5 Packs, one PCS, an electrical system (integrating a high - voltage box and a power distribution system), an EMS, a liquid cooling system, and a fire - fighting system. The system uses Weilan semi - solid - state 280Ah lithium iron phosphate battery cells as the minimum unit for energy storage. It adopts a two - level BMS architecture. In addition to the independent fire - fighting system and pressure relief valve at the Pack level, the system is also equipped with a pressure relief valve.

4. The average daily power generation of one photovoltaic container per year Taking the 715Wp module as an example, one container can be installed with a capacity of 40.04kW. Based on the solar radiation of 2037.6kWh/�?in Abuja, the capital of Nigeria, and a system efficiency of 82%, the calculated power generation hours are 1670.3h. The average daily power generation is as shown in the figure. The daily power generation is approximately 159 - 205kWh, and the power generation is relatively average, with an average daily power generation of approximately 183.4kWh.
5. Other applicable scenarios
1. Permanent/semi - permanent power supply in extremely remote areas:
- Remote villages and communities: Provide electricity for daily life (lighting, communication, TV, small appliances) and necessary public services (water pumps in health stations, lighting in schools) for residents in mountainous areas, grasslands, deserts, and islands where the power grid cannot reach.
2. Resource extraction bases (mines, oil fields, forest farms, islands):
- Provide electricity for production and daily life in exploration camps, operation areas, monitoring equipment, and living areas, getting rid of the dependence on expensive diesel transportation.
3. Border posts and patrol stations:
- Ensure the basic needs of communication, monitoring, lighting, heating/cooling in remote border posts, and improve the garrison conditions.
4. Mobile and temporary high - reliability power sources:
- Emergency rescue and post - disaster reconstruction: When the power grid is paralyzed due to disasters (earthquakes, floods, typhoons), quickly deploy to provide uninterrupted core power for command centers, field hospitals, shelters, and communication relay stations, ensuring the operation of lifelines. In the post - disaster reconstruction stage, supply power for temporary resettlement sites and construction equipment.
5. Temporary camps for major projects:
- Supply power for construction camps, equipment charging stations, and lighting and monitoring systems of projects such as railway/road construction (especially in uninhabited areas), water conservancy projects, and large - scale pipeline laying.
6. Scientific research and exploration bases:
- Provide reliable power sources for scientific research stations in extreme environments such as polar regions, plateaus, and deserts, supporting scientific research equipment and living security.
7. Location shooting sites for film and television:
- Provide stable and silent power sources for equipment such as lighting, photography, and post - production.
For the above scenarios, solutions with different optical storage capacities can be selected according to the actual electricity demand.
