South Africa has achieved more than 300 consecutive days without loadshedding by early 2026, which is significant due to increased private solar investment; Companies installed 5,000MW of new solar capacity within just 18 months of licensing reforms.
Yet energy analysts warn that the country's aging coal infrastructure creates a real supply gap from 2026 to 2030, while Eskom's approved tariff trajectory continues to rise, with direct Eskom customers facing an average electricity price increase of 8.76% from 1 April 2026.
For commercial operators, the financial case for solar power has never been so clear.
At current tariff levels, a commercial solar installation can reach payback in as little as two to three years, with cumulative returns exceeding five times the initial investment over a decade.
In this backdrop, commercial solar buyers are focusing not only on price but also on the long-term performance, warranty protection and bankability of the modules they install.
Solar installed capacity in South Africa alone is expected to grow by about 12% in 2024, reaching almost 9 GW, with the private sector accounting for the lion's share of new installations.

The share of business and commercial sectors in self-generation establishments at the national level is 71%.
Gregor Kuyper, Managing Director of SolarWorld Africa, says: “The South African solar market has matured significantly over the past few years, and our commercial and industrial customers demand much more than competitive pricing; they demand proven performance, reliability and bankable quality.”
“For businesses investing in solar energy, the choice of module has a direct impact on project performance, financing confidence, warranty protection and long-term return on investment.”
“Tongwei represents exactly the same level of assurance,” says Kuyper.
“When you bring a Fortune 500, tier one-rated manufacturer to a market like South Africa, you're not just adding another product to the shelf; you're raising the bar for what businesses here can expect from their solar investments.”
The first stock received includes the Tongwei TNC 2.0 TWMNH-66HD-635 module, which is a high-power N-type TOPCon module designed for commercial, industrial and utility-scale applications.
“We are proud to be the first preferred distributor to introduce Tongwei to South African buyers and to stand behind our reputation behind this product,” says Kuyper.

Headquartered in Chengdu, China, Tongwei is one of the world's largest and most vertically integrated solar manufacturers, controlling the entire supply chain from high-purity crystalline silicon production to finished PV modules.
The company holds tier-one status in the BloombergNEF PV modular tier-one list (New Energy Finance PV) and has an annual module production capacity of approximately 90GW.
