Installing rooftop solar in South Africa is no longer only about keeping the lights on or reducing the amount of electricity you buy from the grid. In some areas, a properly registered solar photovoltaic system can also export unused electricity back into the local network. Depending on your electricity supplier and tariff, that exported energy may earn credits or payments.
The important detail is that South Africa does not have one simple nationwide feed-in tariff for every household. Eskom direct customers and municipal electricity customers can face different tariffs, metering requirements, registration procedures and export rules. Even neighbouring municipalities may compensate solar customers differently. This makes understanding your electricity supplier almost as important as choosing the solar equipment itself.
This guide explains how solar feed-in tariffs work in South Africa, what happened to the household solar tax rebate, how Small-Scale Embedded Generation registration works, and what homeowners should check before designing a system around electricity exports.
What Is a Solar Feed-in Tariff?
A solar feed-in tariff is a rate paid or credited for electricity that a customer generates and exports into the electricity distribution network. A rooftop solar system normally supplies the property first. When production exceeds the home’s immediate electricity demand and available battery-charging capacity, the remaining electricity can potentially flow through an approved meter into the grid.
The electricity supplier measures this exported energy in kilowatt-hours (kWh). Where an approved feed-in programme exists, the exported units are compensated according to the applicable tariff and programme conditions.
How Solar Feed-in Works in South Africa?
South Africa’s system is decentralised because households receive electricity either directly from Eskom or from a municipality. The rules that apply to your property therefore depend primarily on who supplies your electricity.
Municipalities set electricity tariffs subject to the applicable regulatory process, and some municipalities have specific Small-Scale Embedded Generation, or SSEG, tariffs. These can include separate charges for electricity consumed from the network and credits for electricity exported. NERSA tariff schedules demonstrate that SSEG feed-in rates can differ between municipalities, so a rate advertised in one city should never automatically be used when calculating the economics of a system somewhere else.
How Much Can You Earn From Excess Solar Electricity?
There is no single rand-per-kWh figure that applies throughout South Africa. The export value depends on the municipality or Eskom tariff, the customer’s electricity category, the approved meter and sometimes additional tariff conditions.
Cape Town provides a useful example of how structured feed-in arrangements can work. The City’s tariff documentation includes residential and non-residential feed-in arrangements and an additional SSEG incentive component. For the 2026/27 financial year, Cape Town’s budget documentation retained an SSEG incentive of 25 cents per kWh excluding VAT in addition to the relevant feed-in structure.
That figure should not be interpreted as a national rate. Before estimating income, obtain the current tariff schedule directly from the electricity supplier responsible for your property.
Understand Self-Consumption Before Focusing on Export Income
One of the most useful lessons when assessing residential solar is that exported electricity and self-consumed electricity have different economic values. A unit of solar electricity used directly inside the home replaces a unit that otherwise would have been purchased from the grid. An exported unit is compensated according to the supplier’s feed-in rate, which may be considerably different from the retail electricity price.
For many households, this means the strongest financial strategy is not necessarily installing as many panels as possible to maximise exports. A well-designed system usually starts with the property’s daytime consumption profile. Appliances such as pool pumps, geysers, washing machines and other flexible loads can sometimes be scheduled during solar-production hours, increasing the proportion of generated electricity consumed on site.
Register Your Solar System Before Exporting
Grid-connected rooftop solar should not be treated as a plug-and-export arrangement. Customers need to follow the technical and registration requirements of their electricity distributor. These requirements exist because electricity can flow in both directions and the network operator needs assurance that generating equipment will disconnect or behave safely during faults and outages.
Eskom refers to qualifying installations as Small-Scale Embedded Generation systems. In March 2026, Eskom announced that its registration fee waiver for SSEG systems up to 50 kW had been extended until 30 September 2026. Eskom has also been developing a prepaid residential option intended to accommodate rooftop solar customers while meeting metering and registration requirements.
Municipal customers should follow their municipality’s SSEG application process rather than assuming Eskom’s direct-customer procedure applies to them.
Why the Electricity Meter Matters?
A suitable meter is essential if exported electricity is going to be measured correctly. Older meters were generally designed around one-way electricity consumption. Feed-in programmes normally require approved metering capable of distinguishing electricity imported from the network from electricity exported into it.
The meter requirement should be confirmed before the solar installation is finalised. Changing tariffs or installing an approved meter can affect the overall financial calculation, particularly where monthly service, network or administration charges apply.
What Happened to South Africa’s Residential Solar Tax Rebate?
South Africa previously offered a temporary Solar Energy Tax Credit under Section 6C of the Income Tax Act. It applied to qualifying new and unused solar PV panels brought into use between 1 March 2023 and 29 February 2024.
Eligible individual taxpayers could receive a tax credit equal to 25% of the qualifying panel cost, subject to a maximum of R15,000. The incentive applied to qualifying PV panels rather than the complete solar installation. Batteries, inverters and various other system costs were excluded.
This was a one-year incentive and should not be presented as a current rebate for someone installing a new residential system in 2026. Homeowners considering solar today should therefore check current SARS, national government, Eskom and municipal information rather than assuming the former R15,000 incentive remains available.
Steps to Start Selling Extra Solar Power
First, identify whether your electricity account is supplied by Eskom or your local municipality. Next, obtain the current SSEG rules and tariff schedule for that specific distributor. Confirm whether residential feed-in is available, what tariff category is required and whether fixed charges apply.
Before purchasing equipment, choose an installer familiar with local grid-connection requirements. The inverter and associated protection equipment should satisfy the distributor’s technical standards. Complete the required application, obtain the necessary electrical documentation and Certificate of Compliance, and arrange an approved meter where required.
Only after the installation has been approved for grid connection should export compensation be treated as part of the system’s expected financial return.
Calculate the Economics Before Increasing System Size
A practical calculation should compare annual solar generation, daytime household consumption, expected battery charging, estimated exports, the applicable export tariff and any additional monthly charges associated with the feed-in tariff.
For example, if a household expects to export 2,000 kWh annually, the calculation should use its own distributor’s current compensation rate rather than a tariff found for another municipality. The result should then be compared with additional metering, tariff or system costs. This provides a much more realistic picture of the value of exporting electricity.
Common Mistakes South African Solar Owners Should Avoid
A frequent mistake is designing an oversized installation primarily around expected export payments. Tariffs can change, and the retail price paid for electricity should not be confused with the rate received for exported electricity. Another mistake is installing equipment first and investigating SSEG approval afterwards.
Homeowners should also avoid assuming that every municipality follows Cape Town’s model. South Africa’s municipal electricity environment varies considerably. Current tariffs, technical requirements and application procedures should always be verified with the actual distributor before financial decisions are made.
Questions and Answers
1. Can I sell excess solar electricity back to the grid in South Africa?
Yes, this is possible in areas and tariff categories where the relevant electricity distributor permits residential or commercial SSEG feed-in. The system normally needs to be registered and technically compliant, and appropriate metering must be installed. Availability and compensation depend on whether you are supplied by Eskom or a municipality.
2. Is there one national solar feed-in tariff?
No. South Africa does not have a single household export rate that can be applied to every property. Eskom and municipalities have their own approved tariff structures and requirements. Always use the current tariff applicable to your specific electricity account when calculating expected returns.
3. Does Cape Town pay households for excess solar power?
The City of Cape Town has established SSEG feed-in arrangements that allow qualifying customers to receive compensation for exported electricity. Customers must meet the City’s registration, metering and tariff requirements. Current rates should be checked against the latest City tariff schedule because electricity tariffs are reviewed periodically.
4. Is the R15,000 residential solar tax rebate still available?
No for a new 2026 residential installation. The Section 6C Solar Energy Tax Credit was a temporary incentive applying to qualifying panels brought into use from 1 March 2023 through 29 February 2024. Eligible taxpayers could claim 25% of qualifying panel costs up to R15,000, subject to the applicable requirements.
5. Do I need to register my rooftop solar system?
A grid-connected generating installation needs to comply with the requirements of the distributor serving the property. Registration is particularly important where the system operates in parallel with the grid or exports electricity. The exact application and technical process differs between Eskom and municipalities.
6. Can I use an ordinary electricity meter for solar feed-in?
Not necessarily. Export compensation requires accurate measurement of electricity moving between the property and the network. Feed-in programmes may therefore require a specific bidirectional or smart metering arrangement. Confirm the meter requirements with your distributor before assuming your existing meter can support compensated exports.
7. Is selling electricity more valuable than using my solar power at home?
Often, using solar electricity directly can have greater economic value because it avoids purchasing that electricity at the applicable retail tariff. Exported electricity is compensated according to a separate feed-in rate. The exact comparison depends on your tariff, so both rates should be included when calculating system savings.
8. Do I need a battery to export solar electricity?
A battery is not what makes grid export possible. A grid-connected PV system can potentially export surplus production when generation exceeds household demand, provided the installation and tariff allow it. Batteries instead store energy for later use and can increase self-consumption, so their value should be evaluated separately.
9. How can I increase the financial value of my solar system?
Start by matching generation with the home’s electricity-use pattern. Moving flexible loads into daylight hours can increase self-consumption. After that, evaluate battery storage and grid exports based on actual tariffs and costs. Designing around measured consumption generally produces a more reliable financial estimate than simply maximising panel capacity.
10. What should I check before installing solar for feed-in?
Confirm your electricity supplier, current SSEG rules, export tariff, required meter, fixed charges, inverter standards and application procedure. Ask the installer to explain expected annual generation, self-consumption and exports separately. Most importantly, base the calculation on current official tariffs rather than assumptions about what the grid will pay.
Conclusion
Solar feed-in can add another layer of value to rooftop PV in South Africa, but it should be approached as part of a complete energy strategy rather than guaranteed income. The best starting point is usually reducing electricity purchased from the grid through efficient self-consumption, then evaluating whether exporting the remaining surplus makes financial sense.
Because Eskom and municipal rules differ, homeowners should verify current SSEG registration requirements, metering costs and feed-in tariffs before installing or expanding a system. With the right system design and approved grid connection, surplus rooftop solar can become a useful additional benefit while supporting a more distributed electricity supply.
