Traditional financial advice preaches spending less, saving more and preparing for uncertainty. Yet, today’s energy-volatile world calls for a new approach: eliminating recurring expenses that are difficult to control. Energy sits at the centre of this shift.
With Eskom tariff hikes rising again, most recently, the National Energy Regulator of South Africa (NERSA) approved a 12.74% increase alongside municipal hikes, with an 11.32% increase affecting municipal tariffs. Electricity is no longer a stable line item. It is one of the fastest-moving costs in the average budget.
This isn’t just an issue we are facing locally, but Global energy markets remain tightly interconnected, meaning geopolitical tensions from supply chain disruptions to key regions can filter through into electricity prices at home. For South Africans, that translates into a simple reality: energy costs are increasingly unpredictable and largely out of their control. The only way you can plan financially in an environment like this is to eliminate what you can’t control.
From saving to removing risk
It’s no secret that essential utilities are rising faster than income growth. Against this backdrop, reducing or stabilising recurring expenses can deliver an equally, if not more, powerful financial outcome than traditional savings strategies.
Electricity is a prime example. Solar changes the equation. Instead of being fully exposed to grid pricing, households and businesses can generate a portion of their own energy, reducing both costs and volatility.
This has led to a surge in private solar installations in recent years. According to the Council for Scientific and Industrial Research (CSIR), private solar power supported 5% of the country’s electricity demand in the first half of 2025, with embedded rooftop solar capacity reaching approximately 6.8 MW by mid-2025. This is an increase of 403.7% since 2021, reflecting a practical economic decision rather than merely one driven by environmental awareness.
Investments in renewable energy are increasingly attractive as they address two critical priorities simultaneously: cost certainty and sustainability. For businesses and households alike, renewable technologies, such as solar, enable long-term energy price stability by reducing reliance on volatile grid tariffs and fossil-fuel generation. In South Africa, in particular, where electricity prices have historically increased above inflation, renewable energy provides a hedge against escalating energy costs and supports long-term financial planning.
From dependence to control
What makes solar different from traditional utilities is its underlying cost structure. Grid electricity is exposed to multiple inflationary pressures: fuel prices, infrastructure costs, policy decisions, and global supply chains. Solar, by contrast, relies on a single, abundant input, sunlight.
Once installed, the marginal cost of generating electricity is low. And that changes everything.
It introduces a level of cost predictability that traditional energy sources simply can’t offer. In a world of rising and uncertain prices, that predictability starts to look a lot like an inflation hedge.
In an environment where disposable income is under pressure, saving isn’t always about putting more money aside. It’s about reducing exposure to the things that erode it. Stabilising energy costs, removing volatility and turning a fixed expense into a controlled one is where solar can play its part.
