Background
Africa has abundant renewable energy resources such as solar energy and wind energy. The Sahara Desert provides a large area of sunshine, which is an ideal place to promote photovoltaic energy. Africa’s long coastline provides unique conditions for offshore wind energy development. These natural endowments provide possibilities for green solutions for African electricity.
Mali, located in western Africa, has always faced a shortage of electricity resources, and the rural electrification rate is less than 20%. A local village has no electricity supply, and solar energy is the only source of electricity. However, due to unstable light and insufficient energy storage capacity, the generated electricity is difficult to fully utilize at night or in rainy weather, resulting in unstable power supply and unable to meet the basic living needs of residents.
Solution
To address this problem, SCU provided Mali with an integrated solar energy storage system, which achieved efficient consumption and dynamic scheduling of photovoltaic power through integration with the existing solar energy system. The solution provides continuous and stable power supply to local residents in the absence of power grid by storing excess solar power during the day. The specific solutions include:
System integration: GRES energy storage system, with a battery capacity of 75kWh and a PCS of 50kW, seamlessly connects with the 23kWp solar system to form an integrated power supply solution, which can store excess power and release it in time when demand peaks.
Off-grid operation: In the absence of mains electricity, the system uses energy storage technology to make up for the instability of traditional solar power generation, ensuring that reliable power can still be provided to residents at night and under low light conditions.
Smart scheduling: With the help of the smart energy management system (EMS), the system can be dynamically adjusted according to the actual load and photovoltaic power generation conditions to maximize energy utilization and reduce power waste.
Achievements and prospects
Through the solar energy storage solution, residents in rural areas of Mali finally have access to a stable and reliable power supply, which not only improves living conditions, but also lays a solid foundation for local economic development and green agriculture, education, medical and other infrastructure construction.
This project not only provides a successful example for rural electrification in Africa, but also demonstrates SCU’s technical strength in the integrated application of energy storage and renewable energy. SCU has brought light to many parts of Africa. SCU will continue to promote energy storage technology, help more remote areas achieve energy transformation, and contribute to the electrification of remote rural areas in Africa.
