Food for thought

The SMILE 5 Hybrid with battery back-up gives you the ability to produce your electricity at around half the cost of what you are paying Eskom for the same. And that’s at today’s Eskom price! Consider what you will be paying for the next 3-5 years with annual combined Eskom and municipal escalations of at least 15-20%, compounded year-on-year.

This year, you’re paying R400 more on a R2000 bill, next year that’s R880 more than this year, in the third year it’s R1 456 more. Keep doing those sums for the next 10 years – it’s entirely unaffordable and unsustainable.
With your own Smile-5 hybrid solar PV system with battery back-up, you will hedge your electricity costs for the next 15-20 years at R1/kWh.

Here’s how it works:

  • Daily electricity available with Smile-5 if battery is discharged once per day = 5,2 kW
  • Total cycles in battery lifetime = 10 000
  • Cost of battery = R52k
  • Total electricity produced over lifetime = 52 000 W
  • Average cost per kW = R1.00

This is PHENOMENAL if compared to the current domestic cost of electricity of over R2.00 per kW in most municipal areas. It makes more sense to charge these batteries during the day and use a substantial portion of the available power during night at a MUCH lower rate than Eskom power. (Just remember to retain 30% to 40% as a reserve in case of a power outage or load-shedding – your One Energy installer will set this all up for you.)

Remember, as of 1 July, all municipalities also implement their price increases on top of Eskom’s most recent hikes, which means you will be paying anywhere between 15-20% more on your electricity account from this month.
