Net metering quality

Quality of net metering policy (higher = better for solar economics):

Fair — City of Cape Town SSE feed-in

What this means

Fair net metering policies pay less than retail for exports. Consider self-consumption or a battery.

Example: 900 kWh/month household in Cape Town

At 5.0 peak sun hours and a 400W panel, you'd need approximately 17 panels (6.8 kW system) to cover your usage. That produces ~10,673 kWh/year, saving about R34,152/year at the 3.2/kWh local rate.

Going solar in Cape Town

Cape Town, in Western Cape, South Africa, has 5.0 average peak sun hours per day — excellent for solar. The local electricity rate is R3.2/kWh, which is above the South Africa average.

Net metering in Cape Town is rated fair. City of Cape Town SSE feed-in. This significantly affects solar payback: with excellent net metering, every excess kWh you produce is credited at full retail value; with poor net metering, exports may be worth only 10-30% of retail, making battery storage much more attractive.

Available incentives include: SARS s12B deduction, City SSE tariff. These can substantially reduce the upfront cost of solar and battery installations. Note: the US federal solar tax credit expired December 31, 2025. State and local incentives still vary by region. South African taxpayers can claim accelerated depreciation under SARS section 12B.

Next steps

Use the Solar Panel Sizing Calculator with 5.0 peak sun hours to find out exactly how many panels you need. Then check the Solar Savings Calculator for a 25-year projection using the local R3.2/kWh rate. If net metering is poor in Cape Town, also run the Battery ROI Calculator — batteries may be essential rather than optional.
