The Role of International Collaboration
South Africa’s R17.5 billion worth of imported solar panels illustrates the country’s increasing reliance on international suppliers to meet rising renewable energy demands, especially China, the global leader in solar panel manufacturing. The South African government and private sectors have begun to recognize the significance of domestic solar production, with investments underway in manufacturing facilities for components. Reducing production costs could make solar installations more accessible to businesses and households, hastening adoption.
A significant milestone in this global effort is the partnership between South Africa and China to establish a solar panel assembly plant in Mpumalanga, South Africa. In October 2025, South Africa’s Nkangala District Municipality and China’s Wucheng Municipality signed a $35 million agreement to construct a solar panel assembly plant. The first phase, valued at $10 million, is expected to create 150 to 200 jobs. This initiative supports South Africa’s shift away from coal-based energy by increasing access to renewable power.
The project is expected to generate skilled employment and attract further investment in the renewable energy sector. Solar manufacturing requires technical expertise, creating opportunities for local training and workforce development. By producing solar panels domestically, South Africa reduces reliance on imported equipment and insulates itself from supply chain disruptions. The International Renewable Energy Agency (IRENA, 2024) notes that local manufacturing enhances energy security and stabilizes markets during global interruptions. South Africa’s Nationally Determined Contributions (NDCs) under the Paris Agreement include a target of achieving 20 GW of solar capacity by 2030. Expanding domestic manufacturing aligns directly with this vision.
The Potential of Battery Energy Storage Systems (BESS)
Energy Conversion: Battery Storage Can Transform the Grid | Pew
South Africa is increasingly looking to battery energy storage systems (BESS) as a practical solution to its chronic grid instability and persistent power shortages. These systems offer a scalable, cost-effective method to balance electricity supply and demand, enhance grid reliability, and reduce reliance on coal-fired power. According to a June 2024 report by the International Institute for Sustainable Development (IISD), integrating lessons from successful global BESS deployments-in regions like South Australia and California-could significantly improve South Africa’s energy resilience.
Eskom has already begun implementing large-scale projects, such as the 20 MW/100 MWh Hex BESS in Worcester, which is the largest of its kind on the continent. This forms part of a national rollout plan involving 1,440 MWh of battery storage across 12 locations. In parallel, independent producers are developing hybrid renewable energy facilities like the Oya Hybrid Power Station in the Western Cape, which will combine solar, wind, and battery storage to deliver reliable, dispatchable energy.

Mulilo and Scatec have also been named preferred bidders for five large-scale battery storage projects worth R9.5 billion under South Africa’s Battery Energy Storage IPP Procurement Programme. The projects, totaling 616 MW/2 464 MWh, will be developed at substations in the Free State and are expected to be operational by January 2028. All will use lithium-ion technology and contribute to grid stability and peak demand management. These projects represent continued progress in South Africa’s transition to a low-carbon energy system, as outlined in the Integrated Resource Plan framework.
These developments suggest that BESS can not only support South Africa in managing load-shedding but also help modernize the power grid, extend electrification to underserved areas, and accelerate the country’s transition to a more sustainable energy mix.
The Impact on Communities
To the people of Mbiabet Esieyere and Mbiabet Udouba in Nigeria’s deep south, sundown would mean children doing their homework by the glow of kerosene lamps, and the faint thrum of generators emanating from homes that could afford to run them. Most of the residents had never heard of solar power either. When, in 2021, a renewable-energy company proposed installing a solar “mini-grid” in their community, the villagers scoffed at the idea of the sun powering their homes.
The small installation of solar panels, batteries and transmission lines proposed by the company Prado Power would service 180 households in Mbiabet Esieyere and Mbiabet Udouba, giving them significantly more reliable electricity for a fraction of the cost of diesel generators. Village leaders agreed to the installation, though many residents remained skeptical. But when the panels were set up in 2022, lights blinked on in the brightly painted two-room homes and tan mud huts dotted sparsely through the community. At a village meeting in September, locals erupted into laughter as they recalled walking from house to house, turning on lights and plugging in phone chargers. The solar panels installed by renewable energy company Prado Power in the Nigerian village of Mbiabat Esieyere are shown here behind wire fencing.
