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.
We don't sell you a battery for load shedding. You'll never own this equipment, and you'll never own its problems — no instalments, no credit application, nothing on your credit record.
GWA installs a complete solar and battery system at your home at zero cost to you. We own every component. Maintenance, repairs, and performance are our responsibility for the full 15-year term — built into your rate, never billed separately.
Nothing. Your only obligation is the electricity you actually use — starting at R3.30/kWh, escalating at a fixed 5% a year, locked for 15 years. Your municipal account stays exactly as it is.
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 Direct: Homepower 4 tariff, Eskom Schedule of Standard Prices, effective 1 April 2026. City Power: Residential Prepaid High, City of Johannesburg FY2025/26 tariffs. Ekurhuleni: Tariff B (Residential), Schedule 2 Electricity Tariffs 2025/26. All figures at 650kWh/month. Escalation projections use Eskom's 10-year average (10.8% p.a.) against GWA's contractual 5%. Projections are illustrative — actual future tariffs may differ.
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.
The electricity you use. Per kWh. That's it.
Alongside our PPA offering, GWA does general electrical work across Gauteng — DB upgrades, compliance certificates, fault finding, new circuits. R650/hr, quoted upfront.
See Electrical ServicesWe'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. We built GWA to give Gauteng homeowners a proper way out. Your own supply, at a fixed 5% annual escalation, locked in writing for 15 years. We're not going anywhere.
Correct — and you never own the problems either. No maintenance bills, no failed inverter at your cost, no degraded battery to replace in year nine.
No. There's no credit application, no debt, and nothing on your credit record. You're buying electricity, not financing hardware.
The PPA transfers to the new owner via a Deed of Assignment — a rate below market with a fixed escalation is a selling point, not a liability.
It's our equipment; it's our problem, for the full term. Built into your rate — never billed separately.
Your municipal account stays open and untouched. Our system supplies your home independently.
