Explore how the rise of rooftop solar power in South Africa is impacting commercial insurance policies. Learn about the importance of updating insurance coverage for solar installations and the risks businesses need to consider.
The National Transmission Company of South Africa (NTCSA) estimates that rooftop solar power reached 7.345 gigawatts (GW) towards the end of 2025.
The accelerating move by South African businesses towards energy independence, through solar PV installations, battery energy storage systems, generators, and hybrid micro-grids, is reshaping the short-term commercial insurance landscape in ways that many business owners have not fully anticipated.
From an ESG perspective, the decision to go off-grid is overwhelmingly positive; it reduces a business's carbon footprint, decreases dependence on Eskom's coal-heavy generation mix, demonstrates environmental stewardship to investors, lenders, and customers, and contributes to the broader energy transition that South Africa's Just Energy Transition commitments demand.
Responsible insurers and their reinsurers are increasingly attuned to this shift. Globally, underwriters are under growing pressure from their own ESG frameworks and investor mandates to favour clients whose risk profiles align with sustainability objectives, and a business that has invested in renewable energy infrastructure is, in principle, signalling a long-term, forward-looking approach to risk management that insurers should regard favourably.
