Leading Chinese solar technology firm LONGi recently unveiled its new battery energy storage system (BESS) solutions at a side event during the Africa Energy Forum (AEF) 2026. The launch was underscored by a landmark 300 MW solar-plus-storage agreement with SOLA, a South African renewable energy developer.
The launch event drew senior industry leaders including the CEO of South African Photovoltaic Industry Association (SAPVIA), Dr. Rethabile Melamu, who served as guest of honour. LONGi Vice President Louis Liu was also in attendance.
The gathering underscored LONGi’s growing presence in Africa’s energy sector, as the company advances integrated, end-to-end photovoltaic (PV) and storage solutions designed to accelerate the continent’s clean energy transition.
According to LONGi, the agreement with SOLA represents a milestone for the company in the region, combining large-scale solar generation with storage to improve grid stability and energy reliability.
LONGi showcased its BESS portfolio, including the M5 microgrid system, designed for weak-grid and off-grid environments. The system enables seamless switching between grid and off-grid modes with zero-millisecond transfer, while supporting scalable deployments from 250 kW to 6 MW. It is also designed to reduce diesel generator consumption by up to 80% and integrates long-life lithium iron phosphate batteries exceeding 8,000 cycles.
“Today, our customers expect more than PV technology alone. They are seeking integrated solutions, long-term reliability, and partners who can support them throughout the entire lifecycle of their projects. That is why we are introducing the LONGi ONE Strategy – One System. One Platform. One Responsibility,” Mr. Louis Liu, LONGi Vice President.
LONGi highlighted that its participation at AEF 2026, held from June 16 to 19 in Cape Town, presented a platform to showcase the company’s portfolio of high-efficiency solar modules engineered for performance in Africa’s operating conditions.
Products on display included the Hi-MO series and advanced module technologies featuring anti-hail and anti-glare with enhanced durability characteristics. LONGi also highlighted its latest high-efficiency solutions, including modules achieving up to 25.54% efficiency and enhanced structural resilience for extreme environments.
The company said these technologies are tailored to improve performance and reliability in high-temperature, high-irradiance markets across the continent.
