As South Africa’s load-shedding crisis has eased, one might expect a decline in the demand for rooftop solar systems. Yet, the opposite is happening, with the demand for solar installations remaining high and even increasing. This surge is driven by escalating electricity costs, prompting homeowners to seek alternative and cost-effective solutions.

    Why Rooftop Solar Remains in High Demand

    Although load shedding was a key motivator for many to invest in solar power, the persistent rise in electricity prices is now the primary driver. According to data from Standard Bank’s LookSee platform, there has been a significant increase in visits to their Solar Loan finance page, suggesting that many South Africans are seriously considering solar as a viable option. The increases in electricity tariffs, announced for 2025, have made solar energy even more attractive as a means to reduce electricity expenses.

    Marc du Plessis, from LookSee, highlighted that interest in solar surged particularly during July when municipalities implemented annual tariff hikes. A further boost in interest followed Eskom’s announcement of proposed tariff increases—36% for direct customers and 43.5% for municipalities in 2025. This trend has tripled interest in solar since the first half of the year.

    Economic Factors Fueling Solar Growth

    The South African energy market has been challenged by annual tariff increases that have consistently outpaced inflation. This reality has made rooftop solar a more financially appealing alternative for many households. Research from Sustainable Energy Africa supports this, showing that the cost of solar panels has decreased by over 10% annually, while Eskom’s prices have steadily increased.

    Despite the higher initial investment, solar is increasingly seen as a long-term solution to not only address load shedding but also to combat rising daytime electricity costs. Some banks have responded to this trend by introducing loan options for residential solar systems, aiming to make the transition to solar more accessible.

    Challenges Facing the Solar Market

    One of the key challenges for the solar industry is affordability. While solar installations have become more cost-effective over time, the upfront costs remain a barrier for many. Energy economist Lungile Mashele pointed out that many South Africans have had to take out loans or enter contracts exceeding R100,000 to afford a solar system. Additionally, the quality of solar components is crucial, as lower-quality parts can affect the efficiency and lifespan of the system.

    To expand solar adoption, the industry must develop attractive and affordable options without compromising on quality. There’s also a growing emphasis on seeing solar installations as part of the country’s broader goal of decarbonization, not just a quick fix for electricity cuts.

    Future Outlook for Rooftop Solar in South Africa

    The future looks bright for rooftop solar as residential interest continues to grow, driven by both environmental awareness and economic necessity. The anticipated electricity price hikes will likely keep demand for solar systems strong, especially for homeowners looking to gain energy independence and lower their utility bills.

    While solar installations are not cheap, they offer the potential for significant long-term savings, making them an increasingly popular choice. This trend underscores a shift in the energy landscape in South Africa—one where renewable energy sources play a more dominant role in meeting household energy needs and reducing reliance on the grid.

    In conclusion, the demand for rooftop solar in South Africa shows no signs of slowing down, despite reduced load shedding. With rising electricity costs and a push toward sustainability, solar remains a compelling option for households seeking cost-effective and environmentally friendly energy solutions. As the market matures, making solar more affordable and accessible will be key to meeting the country’s growing energy needs.
