Take control of your
electricity — for good
Eskom's era of predictable, affordable power is over. Gridstone gives homeowners and businesses a structured path out — funded solar systems designed around your property, your usage, and your future.

cheaper. Ever.
The grid that powered South Africa for a century is no longer a reliable, affordable foundation for your home or business. The numbers make that clear.
Eskom tariff increase since 2007
What cost R1 in 2007 costs over R6 today. The trajectory has not changed and is not expected to.
Average annual increase for the last decade
Every year your electricity bill grows — without your usage changing. That compounds fast.
Typical inverter replacement cost at year 8–10
Most people who bought solar didn't budget for this. Most systems quietly underperform long before it fails.
The old way vs
the Gridstone way
More than just solar.
A complete energy solution.
We don't sell panels. We design, fund, install, and operate your energy system — then hand it over to you at the end. That's a fundamentally different proposition.
Design
Every system is sized around how your home or business actually uses power — not a generic package designed to shift stock.
- We map your actual usage pattern, not averages
- System sized to your daytime load and roof layout
- All council, Eskom, and COC approvals handled
Structure
We fund the system. You choose how you engage — PPA, fixed lease, or cash purchase. We structure it around your cash flow and goals.
- PPA — pay only for the power generated
- Fixed lease — predictable monthly cost, lower than Eskom
- Cash purchase — own it outright from day one
Operate
Once live, we watch the system every day. We fix what breaks. We bill you transparently. You just pay less for electricity.
- Live system monitoring, every day from our side
- All maintenance and repairs — no callout fees
- Honest, itemised billing — no surprises
Built for business.
Built for homes.
The same funded model, structured differently for each audience — because a family home and a warehouse have different needs, different numbers, and different goals.
