SA sunshine ≈ 145 kWh per kWp per month. Self-use is how much of the solar you actually use - a battery pushes this toward 90-95%. Tariffs vary by municipality and usually rise each year.

These figures are estimates to help you plan, not a guarantee. Real savings depend on your actual usage, roof orientation and shading, your municipal tariff, and whether you add a battery. For an exact figure, request a custom assessment and we'll size a system with a vetted partner installer.
