The solar industry in South Africa is entering an exciting phase of growth and transformation as the country addresses its energy challenges and taps into renewable energy. South Africa's abundant sunlight makes it ideal for solar energy production, which has increasingly gained traction over recent years. As the country grapples with a persistent power crisis, rising energy costs, and the environmental impact of coal-based power generation, solar energy is set to play a key role in the nation's energy landscape. Here's an outlook on the solar industry in South Africa for 2025 and 2026, highlighting expected growth, Eskom's strategies, and the private sector's role in leading the shift toward renewable energy.
Expected Growth in the Solar Industry
South Africa’s solar industry has witnessed impressive growth due to both government initiatives and private sector investments. The shift to renewables, especially solar, is accelerating as the country works toward reducing its dependence on fossil fuels. In 2025 and 2026, the industry is expected to grow at an annual rate of around 10-12%, driven largely by increased investment in large-scale solar farms and growing demand for rooftop solar installations across residential, commercial, and industrial sectors.
The government’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) has been instrumental in attracting investments in solar energy. As of recent rounds, REIPPPP has received significant interest, especially from international investors, and has enabled the addition of substantial megawatts of clean energy to the national grid. Continued support for REIPPPP, along with incentives for small-scale and residential solar projects, will likely maintain this upward trend.
Eskom's Sustainable Power Plans
Eskom, South Africa's public utility, has been at the center of the country's power crisis, struggling with aging infrastructure, high debt, and an over-reliance on coal. However, Eskom has set ambitious plans to transition toward more sustainable power sources, including solar energy. As part of its Just Energy Transition (JET) strategy, Eskom is planning to decommission several coal-fired power stations by 2030, with a commitment to replace this capacity with renewable energy sources, predominantly solar and wind.
In 2025 and 2026, Eskom is expected to play a more active role in renewable energy by fostering partnerships with private solar energy providers and enabling grid access for independent power producers (IPPs). This partnership model aims to decentralize the energy supply, reducing the load on Eskom and creating a more resilient energy infrastructure. Additionally, Eskom is developing grid-scale battery storage projects to stabilize the grid and make intermittent solar power more reliable. If Eskom can overcome financing and implementation challenges, its plans could serve as a major catalyst for sustainable power.
The Role of the Private Sector
In recent years, the private sector has taken the lead in promoting renewable energy independence in South Africa. Many businesses, particularly in the commercial and industrial sectors, have turned to solar power as a solution to mitigate load shedding and rising electricity costs. By investing in self-generation and off-grid solar solutions, private companies are decreasing their reliance on Eskom and reducing their environmental impact.
Financial institutions and corporate giants are also increasingly focusing on sustainable energy by offering green bonds and financing solar projects. Additionally, several mining companies have set ambitious goals to reach carbon neutrality and are investing heavily in solar power as a way to reduce operational emissions. These moves are transforming South Africa’s energy market, with the private sector driving a significant portion of new solar installations.
Looking Ahead
The period between 2025 and 2026 holds great promise for South Africa’s solar industry. With the combined efforts of the government, Eskom, and private sector players, the country is poised to accelerate its transition to renewable energy. Challenges, such as financing, regulatory barriers, and infrastructure limitations, remain, but the outlook is positive. By continuing to leverage its abundant solar resources, South Africa is not only addressing its power crisis but also making strides toward a greener, more resilient energy future
