Commercial Solar SSEG Registration Cape Town covers the authorisation every grid-connected business solar or battery system needs from the City of Cape Town, and the related NERSA registration for larger systems. Compare quotes from installers and engineers who handle commercial SSEG applications.
SSEG stands for small-scale embedded generation. In the City's supply area, generating systems up to 1 MVA connected to residential, commercial or industrial premises need authorisation before they are installed. This page summarises the process; the City's current published requirements always take precedence.

Get Up To 5 Commercial Solar QuotesWhat Needs SSEG Authorisation
- Grid-tied solar PV systems, whether or not they export.
- Hybrid solar and battery systems.
- Battery-only systems that can connect to the grid.
- Expansions of existing approved systems.
- Changes of inverter to a different make or capacity.
Since October 2023 the City treats new solar and battery systems as grid-tied, including standby and battery-only setups, because of the risk of unsafe parallel operation with the network. Solar water heaters that heat water directly do not need SSEG authorisation.
NERSA Registration
NERSA confirmed in February 2026 that:
| Installed capacity, with a grid connection | Register with |
|---|---|
| 100 kW or less | The relevant distributor - Eskom or the licensed municipality |
| More than 100 kW | NERSA directly, in addition to distributor approval |
| No point of connection to the grid | Exempt from registration |
Whether you export or not makes no difference to the requirement.
The City Of Cape Town Process
| Stage | What happens |
|---|---|
| 1. Application | Installer submits the SSEG application with system specifications, single-line diagram and inverter details |
| 2. Review | The City checks the inverter against its approved list and assesses network capacity; it may inspect the meter and connection |
| 3. Permission to install | Written permission issued; installation should not start before this |
| 4. Installation | System installed to the approved design |
| 5. Commissioning documents | Commissioning report, Certificate of Compliance, final circuit diagram and signed supplementary contract submitted |
| 6. Approval | The City issues final approval; meter and tariff changes are made if applicable |
Larger commercial systems require sign-off by an ECSA-registered professional engineer or technologist. Very small installations can have simpler sign-off paths, so check which applies to your capacity.
Documents Typically Required
- Completed SSEG application forms for the system type.
- Single-line diagram and system layout.
- Inverter make, model and NRS 097-2-1 compliance.
- Proof of property ownership or owner consent, and account details.
- Engineer's commissioning report where required.
- Electrical Certificate of Compliance.
- Signed supplementary contract.
Other City departments are typically not involved for rooftop PV, but installations outside defined parameters, or on heritage-protected buildings, can need planning approvals.
Export, Tariffs And Cash For Power
Approved grid-tied feed-in customers can export surplus and be credited at the SSEG feed-in tariff, which can offset the municipal account. Commercial customers on the City's Cash for Power programme can receive monthly payouts once credit exceeds R5,000. SSEG connections may involve a meter change and different tariff conditions, so ask the City or your installer how your account will be affected.
Fees
The City of Cape Town and Eskom extended their SSEG registration and connection fee waivers to 30 September 2026, for systems within the qualifying limits. Check whether the waiver has been extended again before budgeting.

Unauthorised systems can lead to penalties, disconnection or an order to remove the system, and the City cross-checks aerial imagery. When selling a property, an unauthorised system is a defect that should be disclosed. The fix is to regularise: inspect, correct non-compliant work, replace unapproved inverters if needed, and submit the application with full documentation.
Outside The City's Supply Area
Parts of greater Cape Town and the Winelands are supplied by Eskom or by other municipalities such as Stellenbosch and Drakenstein, each with its own forms and process. Check your electricity account to confirm your distributor.
Regulatory requirements change. This page is general information, not legal advice. Confirm current requirements with the City of Cape Town, your distributor, NERSA or a qualified professional.
Installation and commissioning are covered on Commercial Solar Installation Cape Town.
Frequently Asked Questions
Does commercial solar need SSEG registration in Cape Town?
Yes. Grid-connected solar and battery systems in the City of Cape Town supply area require SSEG authorisation before installation.
Do battery-only systems need SSEG approval?
Yes. The City treats battery systems that can connect to the grid as SSEG, even without solar panels.
When is NERSA registration required?
Grid-connected embedded generation above 100 kW must register with NERSA. Systems of 100 kW or less register with the distributor.
Can I install before approval?
No. The City requires permission to install first. Installing beforehand risks penalties and having to change the system.
Who signs off a commercial SSEG system?
An ECSA-registered professional for larger systems, together with a Certificate of Compliance from a registered electrical person.
How long does SSEG approval take?
It depends on application volumes, completeness and whether network studies are needed. Complete documentation is the biggest factor you control.
Can I register an existing unregistered system?
Yes. It is inspected, brought into compliance, documented and submitted. Unapproved inverters may need replacing.
Are SSEG fees waived?
The City and Eskom extended fee waivers to 30 September 2026 for qualifying systems. Check whether this has been extended.
