Financial Gazette (2025, 17 September). Rooftop solar, now at 7 300MW, overtakes all Eskom’s IPP capacity.
The report states that rooftop solar in South Africa, estimated at about 7,300 MW, exceeded the capacity Eskom buys from independent power producers. The research report behind the wiki page attributes the estimate to the National Transmission Company of South Africa as reported by Moneyweb; the wiki marks the figure as unconfirmed until the estimator is checked. South Africa on the Curve uses it as an example of defensive spending: power supply that households and firms buy privately, counted in GDP as output. Journalism, cited for a recent event only.
