GWA installs a complete solar and battery system in your home — panels, inverter, battery, metering. We own it, we maintain it, we fix it when it breaks. You do one thing: pay for the electricity you use. Starting at R3.30/kWh, with a fixed 5% annual escalation locked in writing for 15 years.
650kWh, this month, four suppliers. This is the number that matters.
That's it. That's the offer. Cheaper than Eskom direct, cheaper than Ekurhuleni, level with City Power — starting this month, not someday.
Eskom's rate has climbed 10.8% a year on average. GWA's is fixed at 5%, in writing, for 15 years. Watch the gap.
A solar-powered electricity supply for your home, and the electrical work to back it up. That's the whole business.
A Power Purchase Agreement means GWA buys the hardware, installs it, and keeps it running. You buy the energy it produces at a fixed rate. Solar becomes what powers your home day to day — not a supplement to the grid, but a replacement for it. The grid stays connected as your fallback. You won't notice the difference, except on your bill.
Our qualified team installs a complete solar system at your home — panels, inverter, battery storage, metering. The hardware belongs to GWA. You carry no equipment risk, no installation cost, and no responsibility for what happens to the technology over time.
Your consumption is metered and billed via a prepaid platform. R3.30/kWh, VAT included, all-in. No connection fees. No demand charges. No line items you have to call someone to explain.
That's the contractual ceiling for 15 years. While Eskom's bills climb faster than you can plan for — 10.8% on average over the last decade — your GWA rate moves by a fixed, agreed amount. You'll know what you're paying next year. And the year after that.
Your rate from day one. It goes up by 5% per year — a fixed escalation, written into your contract and locked for 15 years. Eskom's 10-year average is 10.8% per annum.
If it breaks, you call us and we fix it. No call-out fees, no parts invoices, no debate about whose fault it is. It's our system — it's our problem.
Alongside our PPA offering, GWA does general electrical work across Gauteng — DB upgrades, compliance certificates, fault finding, new circuits. R650/hr, quoted upfront, no subcontractors.
We're a Joburg electrical and energy business, working across Gauteng. We know what it means when the power goes out at 6pm on a Wednesday — and we know what your bill looks like the morning after.
South Africa has a grid that was never built to serve everyone it's been asked to serve. The result is a system that punishes the people connected to it — with outages, with bills that climb faster than you can handle, and with no real alternative. Until now.
We built GWA to give Gauteng homeowners a proper way out. Not a workaround. Your own supply, at a fixed 5% annual escalation, locked in writing for 15 years. We're not going anywhere.
"We've got you. Always."
We don't try to be everything to everyone. Solar PPAs and electrical work. That focus is the reason we're good at both.
Every job — installation, maintenance, fault call — is done by our own qualified team. You'll see the same faces. That's intentional.
We know that. A PPA is not a transaction — it's a relationship. GWA is structured and funded to be here for the full term, and then some. We don't take that lightly.
One point of contact, proper documentation, and no drama. If something needs sorting, you'll know exactly who to call.
Straight answers. If something isn't covered here, call us.
