The South African Photovoltaic Industry Association (SAPVIA) questions both the cost assumptions used for the technology in the draft Integrated Resource Plan 2023 (IRP 2023), as well as the 900 MW yearly build limit placed on distributed solar in its formal submission to the department. SAPVIA’s response, which was submitted ahead of the March 23 deadline for public comments, states that the technology cost assumptions for solar PV have been inaccurately estimated for Horizon 1 to 2030.
