The End Of Low-Cost Solar Imports

South African households and independent power producers are facing a significant increase in the cost of renewable energy infrastructure. According to a recent analysis by Allan Gray, a "confluence of factors" is bringing an end to the period of ultra-cheap solar panel imports. Central to this shift is China’s decision to abolish its 9% value-added tax (VAT) export rebate for solar PV modules and cells, effective April 1, 2026. Given that China manufactures approximately 80% of the world's solar panels and that panels represent roughly half of total project costs, the removal of this rebate injects a substantial new expense into the local energy market.

Geopolitical Risks To Infrastructure Reform

The ongoing war involving Israel, Iran, and the United States has introduced severe "supply chain dysfunction" that threatens South Africa's broader electricity sector reforms. Raine Adams, an ESG analyst at Allan Gray, warns that the conflict has heightened risks for the country’s R440 billion transmission grid expansion. The government’s plan to install 14,000 km of new power lines is heavily dependent on aluminum—an industrial metal currently seeing price volatility and supply constraints due to the war. Without a stable supply of these critical components, the project to integrate 59 GW of new wind and solar capacity over the next 14 years may stall.

Historical Precedent: The Bid Window 5 Warning

Analysts point to Bid Window 5 of the Renewable Energy IPP Procurement Programme (REIPPPP) as a cautionary tale. During that phase, many approved projects became "underwater" and unable to proceed because their initial bids were based on pre-disruption prices. The post-COVID-19 disruptions and the Russia-Ukraine war made those low tariffs unrealistic. Experts fear a similar scenario is emerging today, where the escalation of the Iran war could make current solar and wind project bids financially unviable due to rising shipping costs and extended lead times for imported components.
