As a result, the Levelized Cost of Electricity (LCOE) of solar PV has become highly competitive across multiple segments.

2. Market Segmentation
Market Segmentation: Where Growth Is Concentrating
Utility-Scale Solar: Policy Continuity with Grid Constraints
South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) remains a cornerstone of utility-scale solar development. Bid Window 7 marked a strong recovery, awarding nearly 4,000 MW of PV capacity.
A notable structural shift in 2026 is the emergence of privately developed substations and transmission assets, enabling large independent power producers (IPPs) to bypass grid bottlenecks—particularly in high-resource regions such as the Northern Cape.
Commercial & Industrial (C&I): The Core Growth Engine
The C&I segment has become the most active and resilient part of the market. Mining operations, manufacturing facilities, logistics centers, and retail complexes are accelerating investments in solar-plus-storage systems to secure operational continuity.
The removal of licensing requirements for self-generation projects above 100 MW has significantly boosted private power purchase agreements (PPAs), allowing companies to hedge against grid instability and volatile electricity prices.
Residential Solar: From Early Adopters to Mass Market
After rapid early adoption among high-income households in major cities, residential solar deployment is gradually expanding into secondary cities and middle-income segments. This shift is supported by green financing products, including energy loans and leasing models offered by local banks, which have lowered the entry barrier for homeowners.
