With the 11.2% overall municipal increase arriving on 1 July 2026, the “payback period” for a solar-to-EV installation is shrinking significantly.
While the grid becomes more expensive, your roof remains inflation-proof.
Solar Synergy—Driving on 100% Sunshine
If the April 1st fuel hike was a wake-up call, the July 1st municipal electricity increase is the final confirmation: Self-generation is no longer a luxury; it is a financial hedge.
By July, the highest residential tariff (Step 3) in Gqeberha will climb from R4.57/kWh to approximately R4.93/kWh. While this makes grid-charging an EV more expensive, it makes the ROI of a Straton Solar system even more aggressive.
The Updated Cost Comparison (Post-July 2026)
| Energy Source | Cost per Unit | Cost per 100km* | Monthly Commute (1,500km) |
| Petrol (95 ULP) | ~R25.80/L | R219.30 | R3,289.50 |
| Diesel (50ppm) | ~R29.50/L | R191.75 | R2,876.25 |
| Grid Power (NMBM) | R4.43/kWh | R79.74 | R1,196.10 |
| Straton Solar | R0.00/kWh | R0.00 | R0.00 |
*Based on an EV efficiency of 18kWh/100km and average ICE consumption.
Understanding the ROI: The “Fuel-to-Solar” Pivot
For a Gqeberha resident currently driving a petrol SUV, the monthly fuel bill is roughly R3,300.
By switching to an EV and charging via a Straton Solar installation:
You “save” that R3,300 every single month.
Over 4 years, that totals R158,400 in avoided fuel costs—enough to cover the cost of a substantial solar-and-battery array.
Essentially, your petrol tank is currently “buying” your neighbor’s solar system. By switching, you use that same monthly spend to buy your own energy independence.
The 11.2% “Stealth Tax”
The July 1st increase doesn’t just affect your lights; it affects your mobility if you rely on the grid. By moving your “fueling station” to your roof, you effectively opt out of the annual municipal tariff hikes.
Every time the NMB Council meets to approve an increase, your ROI actually improves. You are locked in at R0.00 per kilometer for the next 20 to 25 years (the lifespan of the panels).
Smart Management with Straton & Shelly
To maximize this ROI, we can integrate your EV charger with Shelly smart-sensing hardware.
The Goal: To ensure your car charges only when your solar production is at its peak.
The Result: You avoid drawing a single kilowatt from the grid at the new R4.43 rate, ensuring your commute remains truly free.
