Ask a household what they spend on electricity and most can answer with accuracy within a hundred Rand. Ask what they will spend in five years and the room goes quiet, and understandably so.

It is not a comfortable calculation, but it is a simple one. South African electricity tariffs have been rising by roughly 12% a year, according to the Department of Mineral and Petroleum Resources’ South African Energy Price Report, and municipal increases often layer on top of the Eskom bulk price.
‍
At that rate, the arithmetic is blunt. A household buying R1,500 of electricity per month today is on course for roughly R2,600 a month in five years, and around R4,700 in ten years’ time. Not because the family used a single unit more. Same house, same geyser, same kettle.

For seventeen years, Prepaid24 has watched this happen from the inside, at the point where tens of thousands of households buy their monthly prepaid electricity units. We watch careful families budget well, buy sensibly, and unfortunately lose ground anyway, year after year. That, more than anything, is why Prepaid24 Energy exists.

Solar changes the shape of the problem. The sun does not send an increase letter. A right-sized system with a fixed monthly rental converts the steepest rising line in the household budget into a flat, predictable one, and for most qualifying homes it costs less than their electricity spend today, from the very first month!
‍
We are careful with that claim, so here is its honest edge: the savings depend on your current spend and your consumption pattern, which is why we check your numbers before we recommend anything. We will also tell you plainly if solar does not yet make sense for your home.
‍
The scary 5-year number is coming either way. The only question is whether you have a plan for it.
