Eskom and municipal tariffs have climbed well above inflation for over a decade, and most municipalities push another double-digit increase through every July. If you’re weighing up solar, the real question isn’t “does it save money” — it’s “how fast does it pay for itself at today’s rising rates.”
A simple way to estimate your payback
Take your average monthly electricity bill and divide it into your system cost. That’s a rough payback period — but it understates the real picture, because tariffs keep rising while your solar cost is fixed the day you install.
| Monthly bill | Typical kit size | Rough payback* |
|---|---|---|
| R1,500–R2,500 | 6–8kW hybrid + 10kWh battery | ~4–6 years |
| R3,000–R5,000 | 10–12kW hybrid + 15kWh battery | ~4–5 years |
| R6,000+ | 16kW+ hybrid, larger battery bank | ~3–5 years |
*Rough estimate only — depends on usage pattern, roof orientation, and how much you self-consume vs would otherwise export. Every household is different; we’ll model it properly on your free quote.
Why payback is getting faster, not slower
Two things move in your favour every year you wait:
- Municipal tariffs rise annually — often 10%+ — so the electricity you’re not buying from the grid is worth more every year
- Load-shedding costs aren’t in the tariff at all — spoiled fridge contents, damaged appliances from surges, security system downtime, lost work-from-home hours. Solar removes those costs entirely, and they don’t show up in a simple bill comparison
Financing makes the maths even better
If a lump-sum payment isn’t the right fit, ask us about payment plan options — the goal is for your monthly solar repayment to land below what you’re currently paying in electricity, so you’re cash-flow positive from month one.
