Money & tariffs
Do municipalities pay for solar feed-in in South Africa?
Some metros credit exports, but usually at less than you pay to import. This page explains net billing vs true net metering, what to verify in Cape Town, Joburg, Tshwane, eThekwini and Eskom areas, and why self-use (and EV daytime charging) beats chasing feed-in income.
Updated 26 October 2026 · Figures are the 2026/27 municipal year (from 1 July 2026) unless stated.
Answer first: Yes — registered residential SSEG customers in the big metros can earn an export credit, but it is usually well under half of what you pay to buy a kWh. For 2026/27 (approx. incl. 15% VAT): Cape Town ~152.93 c/kWh, City Power Johannesburg 143.29 c, eThekwini ~184.60 c, Tshwane ~108.25 c (NERSA RfD). Design for self-use, battery shift and EV daytime charging; treat feed-in as a bonus line on the bill.
Net metering vs net billing vs feed-in (plain English)
| Idea | What it means | SA reality |
|---|---|---|
| Classic net metering | Export kWh offset import kWh 1:1 | Rare as a pure 1:1 consumer product in major metros |
| Net billing / export credit | Exports credited at a published c/kWh, often below retail | Common SSEG pattern where export is allowed |
| No export / zero export | Inverter capped; you still register in many cases | Frequent when metering or tariff is not ready |
2026/27 residential export credits (sourced)
Rates below are from primary municipal / NERSA schedules. Metros usually publish energy charges excluding VAT; we show both. Confirm the figure printed on your account — schedules change every July.
| Distributor | Export credit excl. VAT | ≈ Incl. 15% VAT | Extra SSEG cost to budget | Primary source |
|---|---|---|---|---|
| City of Cape Town (Home User SSEG) | 107.98 c/kWh feed-in + 25.00 c incentive = 132.98 c | 152.93 c/kWh | Home User services/wires + AMI admin where applicable | CoCT Budget 2026/27 Annexure 6 |
| City Power (Johannesburg) | 124.60 c/kWh residential embedded generator | 143.29 c/kWh | Must be on TOU conventional (prepaid SSEG must migrate); bi-directional meter; net-consumer only; ≤1 MW | City Power Annexure A1 + NERSA RfD |
| City of Tshwane | 94.13 c/kWh “credit reverse for excess generated” | ≈108.25 c/kWh | Domestic SSEG fixed line R324.00/month excl. (≈R372.60 incl.) in same NERSA block | NERSA CoT RfD 11 May 2026 |
| eThekwini (Durban) | 160.52 c/kWh residential net-billing energy | ≈184.60 c/kWh | Network access R76.83/kVA of inverter / month excl. (≈R88.35 incl.); credits not paid as cash | NERSA eThekwini RfD 8 May 2026 |
| Eskom direct | Separate SSEG / NERSA processes and tariffs — do not assume metro rates | Eskom Distribution SSEG | ||

Why self-use still beats chasing export
- Retail import in 2026/27 metro bands is often ~R3.30–R4.70/kWh (energy). Export credits above top out around ~R1.50–R1.85/kWh incl. VAT.
- A geyser timer, pool pump or EV wallbox on solar surplus turns would-be exports into avoided imports at the full retail rate.
- Batteries shift midday PV into evening peaks — people’s choice for longevity when that matters: Solar MD among peers on our battery guide.
Metro rules that change the maths
- City Power: residential exporters must leave prepaid for a TOU conventional tariff — budget the fixed/service change, not only the 124.60 c credit.
- Cape Town: residential feed-in sits with Home User; green attributes pass to the City on the standard feed-in tariff; incentive is reviewed annually by Council.
- eThekwini: size the inverter to the loads you need; every extra kVA costs network access every month.
- All metros: unregistered export is unsafe and usually illegal — follow SSEG registration.
Registration is not optional “because I won’t export”
Grid-tied hybrids usually still need SSEG registration. Follow the application checklist. There is no separate national solar tax for registering — see the tariff mythbuster.
