BEIJING – November 12, 2026 -- JA has been selected as the exclusive photovoltaic module supplier for Teraco's 120MW Sediba solar project in Parys, in South Africa's Free State province. The plant is expected to generate more than 354,000MWh of renewable electricity annually, with operations scheduled to begin by the end of 2026.
Teraco will route Sediba power to its data centres through wheeling
Teraco, a provider of carrier-, cloud- and vendor-neutral data centre environments for colocation services, owns the project. Sediba will feed electricity into the national grid. The corresponding renewable allocation will reach Teraco's data centre operations through a power-wheeling arrangement with local municipalities and Eskom.
Technical testing led to JA's selection as sole module supplier
JA won the exclusive supply role after technical evaluation and testing, with Teraco weighing performance, durability and long-term reliability. JA will deliver high-efficiency n-type modules. The site exposes equipment to high summer temperatures, intense solar irradiation, dust, seasonal thunderstorms and significant temperature swings. JA says its modules are engineered to withstand high temperatures, hail and heavy loads while maintaining output.
For Sediba, long-term degradation, mechanical integrity and product consistency shape the project's lifetime generation profile alongside initial power output.
JA cites material traceability and validated climate targets
JA says key materials, including glass and soldering ribbon, can be traced through manufacturing, and that environmental and supply-chain records cover the product lifecycle. The Science Based Targets initiative has validated the company's climate targets. JA also operates nationally recognised green factories.
Large commercial and industrial power users are increasingly adopting renewable generation and wheeling arrangements to secure cleaner electricity and manage long-term energy needs, according to the source.
