Savings minus system cost
These are approximate figures based on a standardized household consumption of 5,000 kWh/year and an estimated electricity rate of R3.77/kWh in South Africa. Local incentives may reduce the upfront cost — check current subsidy, tax-credit, or VAT programs in South Africa, as these can meaningfully shorten the payback period.
Figures are estimates based on typical system assumptions and the latest available electricity-price and billing data for South Africa. Actual costs, tariffs, net-metering rules, and incentives vary by utility and change over time — confirm with a local installer or energy authority before making decisions.
How solar billing works in South Africa
Savings come from using your own power; exports may earn little or nothing.
In South Africa, the main value of rooftop solar appears to come from self-consumption, meaning you save most when you use the electricity your panels produce at the moment it is generated. Energy exported to the grid may earn little or nothing, so systems are often sized and paired with usage habits (or storage) to maximise on-site use. Whether any export compensation exists at all varies by region and utility and should be confirmed locally.

Frequently asked questions about solar in Mthatha
How much do solar panels cost in Mthatha?
A typical 2 kWp residential solar system in Mthatha, South Africa costs approximately R50,000 before incentives — this is an estimate based on typical regional pricing. Local incentives such as subsidies, tax credits, or VAT exemptions may reduce the upfront cost; check current programs in South Africa.
Do you get paid for exporting solar energy in South Africa?
Where solar value comes mainly from self-consumption, the savings in South Africa typically come from using your own generation rather than from exporting it, and any payment for surplus sent to the grid may be small or absent. Shifting usage to daytime hours or adding battery storage can help you capture more of that value. Because export arrangements vary by region and utility and may change, confirm the current rules with a local installer or energy authority.
How much electricity do solar panels produce in Mthatha?
