Do You Need to Register Your Solar System in South Africa?

Ask five people whether you legally have to register a home solar system in South Africa and you will get five different answers. One installer will tell you registration is optional unless you plan to sell power back to the grid. Another will say Eskom cannot force you to do anything on your own property. A neighbour will mention a friend who got a letter threatening a R30,000 fine. All three are repeating something that was at least partly true at some point, which is exactly why the topic feels so murky right now.

This article is about the residential side only, the ordinary rooftop system a household installs to cut its electricity bill or ride out load shedding. Here is where things actually stand for a homeowner in August 2026, including a public argument that played out in the first two months of this year and settled the legal question more clearly than it had ever been settled before.

The short answer

Yes, you need to register a grid-tied solar system with whoever supplies your electricity, Eskom or your municipality, and this applies even if you never plan to export a single unit back to the grid. That is the current legal position, and it was restated in unusually plain language by the energy regulator, NERSA, in February 2026 after months of public confusion about whether it was true.

The official name for what you're registering is Small-Scale Embedded Generation, or SSEG, the term Eskom, your municipality and NERSA all use for a customer-owned generator, almost always solar PV, connected to the grid at household scale. If an installer, a form or a fine notice mentions SSEG, this is what they mean.

Why so many people think exporting is what triggers registration

The confusion has a real source. For years, installers and even some distributors talked about registration mainly in the context of feed-in tariffs and exporting surplus power, which made it sound like a household that only self-consumes, using its own solar during the day and drawing from the grid at night, was somehow exempt. NERSA's February 2026 clarification closed that gap directly. The obligation to register, it said, is determined by two things only: whether the installation has a point of connection to the grid, and its installed capacity. Whether electricity is actually exported or entirely consumed on site does not come into it. A household with panels feeding an inverter that stays wired into the municipal or Eskom supply, even with export permanently disabled, is a small-scale embedded generator in the regulator's eyes and falls under the same registration duty as a household selling power back.

The one system genuinely exempt is one with no point of connection to the grid at all, a fully off-grid setup that never touches municipal or Eskom wiring. For everyone else with a grid-tied inverter and an installed capacity of 100kW or less, which covers essentially every residential system in the country, registration is with your electricity distributor, not with NERSA directly. NERSA only handles registrations for installations above that threshold, which is industrial or utility-scale territory, not a household roof.

The row that forced the clarification

This didn't happen in a vacuum. In late January 2026 the Organisation Undoing Tax Abuse published a strongly worded piece arguing that residential solar owners should hold off on registering, calling recent threats from Eskom and some municipalities to fine or disconnect non-registered households impractical and unfair, and questioning whether there was even a legal basis to compel homeowners to register in the first place. OUTA's underlying point, that what a homeowner does behind their own meter should be nobody else's business provided the installation is safe and the household keeps paying its account, struck a chord with a lot of solar owners who had been putting registration off anyway.

NERSA's response a week later didn't leave much room for that reading. It reaffirmed the registration requirement in detail, and drew a clear line between two things people had been conflating: a Certificate of Compliance confirms your wiring is electrically safe, while registration is a separate regulatory step that keeps distributors informed about what is connected to their network, for planning and grid stability reasons. Getting a CoC does not register you, and registering does not replace the need for a CoC. You need both.

Practically, if you're weighing whether to register, treat the current legal position as settled. It is required.

Who you actually register with

This depends entirely on who bills you for electricity, and the process differs quite a bit by area.

If Eskom supplies you directly, you apply through Eskom's own SSEG channel, which typically wants an application form, your inverter's datasheet, and, once the installation is done, the electrician's Certificate of Compliance. Eskom asks for pre-approval before you switch the system on, not just a notification afterwards.

If your municipality supplies you, each one runs its own process, and they are not identical. The City of Cape Town runs everything through an online Energy Services portal, and since October 2023 every new solar or battery installation there is treated as grid-tied by default and must use a City-approved inverter with professional sign-off before you're allowed to switch it on. City Power in Johannesburg introduced a more formal six-step process in 2026, running from an initial supply notification through a site inspection to a final approval letter, and it has been open about the fact that a backlog of applications, some dating back to 2022, built up faster than it could clear them. Industry body SAPVIA and City Power sat down in April 2026 specifically to work through that backlog and push for faster, more digital processing. If you're in Johannesburg and your application seems to be taking a while, you're not imagining it, and you're not alone.

Other metros, eThekwini, Tshwane, Nelson Mandela Bay and the rest, all publish their own SSEG requirements, usually as a PDF on the municipality's website. The steps are broadly similar everywhere: a compliant, tested inverter, a qualified installer, a Certificate of Compliance, and an application to the distributor before or shortly after switch-on. The paperwork and the waiting time are what vary.

What you'll actually need

Strip away the branding differences between distributors and the requirements converge on a short list: an inverter that meets the NRS 097-2-1 grid-tie standard, installation by a registered electrician who issues a Certificate of Compliance, a completed SSEG or embedded generation application form for your distributor, and in most municipal areas a single-line electrical diagram of the system. Some areas also want a site inspection before final sign-off, particularly for larger installations or ones that include battery storage.

None of this is unusual by the standards of any other electrical work done on a house. It is the paperwork trail, not the technical bar, that trips people up.

There's a real deadline attached to this right now

Eskom has been waiving registration and connection fees, including the cost of the bi-directional smart meter that a registered system needs, for residential systems up to 50kW since March 2023, and it extended that waiver again in March 2026, this time through to 30 September 2026. For an urban household that waiver is worth several thousand rand. After that date the fees return, so if you have an installed system sitting unregistered, or you're planning one, there is a genuine financial reason to get the paperwork moving before the deadline rather than after it. Municipal fee policies vary distributor by distributor, so check your own before assuming the same date applies.

What happens if you don't register

Enforcement has been inconsistent, which is part of why so many households have simply not bothered, but the consequences for the ones who do get caught are not small. Municipalities that do act have issued fines reported anywhere from around R6,000 for a first offence up to R30,000 or more for repeat or serious cases, and there have been cases of forced panel removal in body corporate and estate settings once a system is flagged as unregistered.

The quieter risk sits with your insurer rather than your municipality. An unregistered, non-compliant installation gives an insurer real grounds to decline a claim connected to the system, whether that's fire damage, lightning strikes, or theft, precisely because registration and a valid Certificate of Compliance are the paper trail insurers point to as evidence the system was installed and inspected to a proper standard. A voided claim after a lightning strike or a roof fire is a far more expensive outcome than the registration process itself.

The bottom line

If your system is connected to the grid in any way, register it, even if it never exports a unit. Do it through your actual electricity supplier, Eskom or your municipality, not through NERSA, unless your installation is well outside residential scale. Keep your Certificate of Compliance regardless, because it does a different job to registration and you need both. And if you've been putting it off, the fee waiver gives you a concrete reason to act before 30 September 2026 rather than after.

Frequently asked questions

What is SSEG?

SSEG stands for Small-Scale Embedded Generation, the official term Eskom, municipalities and NERSA use for a customer-owned generator, almost always rooftop solar, connected to the electricity grid at up to 100kW. It is the category your home system falls into and the term used on every registration form.

Do I need to register if I'm not exporting power to the grid?

Yes. NERSA clarified in February 2026 that registration depends on whether the installation has a point of connection to the grid and its installed capacity, not on whether electricity is exported. A self-consumption-only system with export disabled still has to be registered as long as the inverter stays wired into the municipal or Eskom supply.

What happens if I don't register my solar system?

Enforcement varies by area, but municipalities that do act have issued fines reported from around R6,000 for a first offence up to R30,000 or more for repeat cases, occasionally with forced panel removal. Separately, an unregistered, non-compliant installation gives your insurer real grounds to decline a claim for fire, lightning or theft damage connected to the system.

How much does it cost to register a solar system with Eskom?

Eskom has waived registration and connection fees, including the bi-directional smart meter, for residential systems up to 50kW until 30 September 2026. After that date the standard fees apply again, so there is a real financial reason to register before the deadline rather than after it. Municipal fee policies differ and should be checked separately.

Is a Certificate of Compliance the same as SSEG registration?

No. A Certificate of Compliance, issued by your electrician, confirms the wiring is electrically safe. SSEG registration is a separate step with your distributor that tells them what generation capacity is connected to their network. NERSA has stressed the two do not replace each other, you need both.
