South Africa sits at a crossroads when it comes to renewable energy adoption, and our own research into household attitudes towards solar power reveals a startling paradox: the country has some of the world’s best conditions for solar energy generation, yet uptake remains stubbornly low. With sunshine abundant, electricity costs spiralling, and load-shedding becoming a national crisis, you’d think South Africans would be clamouring for rooftop panels. Instead, fear—not finances alone—is keeping families from making the switch.
The numbers tell a troubling story. Despite having massive solar potential, solar power accounts for less than 10% of South Africa’s energy mix, while 74% of our electricity still comes from coal-fired power stations. For those who can’t access the grid, paraffin and wood remain the default energy sources for lighting and cooking. Electricity bills have more than doubled in the past decade, yet the solution sits right above our heads, largely untapped.
As environmental researchers focused on sustainable energy and household consumption patterns, we decided to investigate what’s really stopping families in the Eastern Cape—one of our most economically challenged provinces—from adopting solar technology. Our study wasn’t limited to wealthy suburbs; we deliberately included both affluent and low-income households to understand how economic circumstances shape renewable energy decisions.
We conducted interviews across 49 high-income households (earning over R30,000 monthly) and 94 low-income households in major Eastern Cape cities including Gqeberha, KuGompo City, Makhanda, and Komani. The income disparity was stark: 65% of low-income households had no wages at all, relying entirely on government grants ranging from just R370 to R2,400 per month. The province itself reflects this struggle, with a 42.5% unemployment rate and 65% of families receiving at least one social grant.
We deliberately selected both coastal and inland locations to test whether environmental factors—such as salt corrosion near the coast or dust inland—discouraged solar adoption. What we discovered, however, overshadowed these practical concerns entirely.
The theft fear stopping South Africans from embracing solar power
Almost universally, households across all income levels shared one dominant concern: the fear that solar panels would be stolen. This wasn’t a minor worry buried in a list of secondary concerns—it was the primary barrier to adoption, cutting across class lines in ways that financial and technical obstacles couldn’t explain.
What’s particularly revealing is how this fear manifested differently depending on income level. 60% of wealthier households worried about theft, compared to 52% of lower-income families. You might think poorer communities would fear theft more, but the reality is more nuanced. Wealthy households typically have valuable assets visible on their properties and are acutely aware of crime statistics. For them, solar panels represent an obvious target.
Low-income households face a different psychological calculus. For them, solar isn’t a luxury upgrade—it’s survival infrastructure. If panels are stolen, replacing them isn’t a matter of insurance claims and tax write-offs; it’s impossible. The stakes feel impossibly high, which paradoxically makes even modest risks feel unacceptable. Interestingly, government-supplied solar water geysers in lower-income areas have rarely been stolen, yet the anxiety persists.
Beyond theft concerns, our research identified other obstacles. 86% of high-income households cited cost as the main barrier, while 58% of low-income households did the same. Low-income families additionally worried about maintenance expenses—battery replacements, inverter repairs, technician call-outs—that could consume their already-stretched budgets. About one-third of all respondents, regardless of income, reported concerns about system unreliability during dusty, wet, or adverse weather conditions.
Yet despite these varied concerns, nearly 90% of respondents said they’d choose solar to prevent future load-shedding, having endured years of blackouts between 2007 and 2023. The appetite for change is unmistakably there. Over 80% of wealthy households had seriously considered solar adoption, compared to just 63% of low-income households—a gap that speaks to the compounding effect of financial anxiety.
The traditional approach to solar adoption—individual household installations—clearly isn’t working for South Africa’s diverse economic landscape. We need a solution that addresses the security anxiety of wealthier households whilst simultaneously lowering costs for those struggling to meet basic needs.
This is where community-based solar mini-grids enter the conversation as a genuinely transformative alternative. Rather than each household installing individual rooftop systems, mini-grids involve multiple households connecting to a single, centralised solar installation that generates and distributes electricity throughout the community. Several African nations have already proven the concept works at scale.
In Zambia, Somalia, and Nigeria, mini-grids have successfully electrified communities where extending the national grid would cost prohibitively more. The model transforms several limiting factors simultaneously. First, centralised systems are inherently more secure than scattered rooftop installations—a guarded communal facility is far more difficult to compromise than dozens of isolated panels spread across a township. This directly addresses the theft anxiety that’s paralyzing adoption decisions.
Second, mini-grids dramatically reduce individual household costs. When infrastructure expenses are shared among dozens of beneficiaries rather than borne by a single household, the financial barrier collapses. For low-income families already juggling grant payments and survival expenses, shared costs could mean the difference between adoption and continued dependence on paraffin.
Third, mini-grids solve the space constraint problem. Many homes, particularly in densely populated areas, simply lack suitable rooftop space for effective solar installation. A strategically located community system eliminates this barrier by placing panels where sunlight exposure is optimal.
Fourth, mini-grids strengthen social cohesion. Shared energy systems require cooperative management, which builds community bonds whilst creating local employment opportunities for technicians and maintenance staff. This aligns with principles of just energy transition—ensuring that the move toward clean electricity benefits everyone, not just affluent households with capital to invest.
We’ve presented our findings to policymakers and community leaders with clear recommendations. For low-income areas, government should prioritise setting up guarded communal solar mini-grids rather than incentivising individual household installations. For wealthier suburbs where individual panels are feasible, anti-theft fasteners and motion-sensor security lighting could effectively mitigate theft concerns and unlock adoption among that demographic.
South Africa’s solar story doesn’t have to remain one of untapped potential. The resources exist, the technology is proven, and the motivation is strong. What’s needed now is a policy framework that acknowledges our diverse economic realities and deploys solutions tailored to those realities. Mini-grids represent that possibility—a pathway where communities, not just individuals, can harness the African sun to power their futures.
