City & metro tariff framing
Cape Town, Johannesburg, eThekwini, Tshwane and other distributors price electricity differently. Solar payback follows your tariff — especially fixed charges and whether export credits exist.
New: 2026/27 per-kWh rates by metro and how to work out payback from them.
Answer first: Self-consuming solar almost always beats exporting. Fixed municipal charges do not disappear when you install PV. Confirm current SSEG rules and export schedules with your municipality — they change.
High-level education only — not a tariff schedule. NERSA publishes municipal tariff decisions; metros publish SSEG guides.
- Identify whether you are on Eskom or a metro tariff
- Note fixed/capacity charges vs energy c/kWh
- Ask about bi-directional metering costs
- Model savings on self-use first, credits second
