Installed prices should include panels, inverter, mounting, cabling, labour and a Certificate of Compliance. Always confirm what's included in writing.
What changes the price
- Batteries. Storage is the single biggest cost — a 10kWh lithium battery alone runs around R85,000 installed in published breakdowns.
- Inverter quality. Entry-level hybrid inverters cost far less than premium brands with longer warranties.
- Roof and wiring. Roof type, mounting and the state of your DB board affect labour and compliance costs.
- Sizing. A system matched to your actual electricity bill costs less than an oversized one — published guides suggest sizing from your monthly usage.
Before you accept a quote
- Get at least three quotes — published guidance consistently recommends it for solar.
- Check that the quote includes the electrical Certificate of Compliance and commissioning.
- Ask for panel, inverter and battery brand names and warranty periods in writing.
- Confirm the installer is qualified to issue the CoC (a valid wireman's licence).
- Compare the monthly finance repayment against your actual Eskom bill, not a promised saving.
