Commercial Solar Approvals in South Africa: Checklist

Start with an approval route, not a generic permit list

Ask these questions at concept stage:

1. Who supplies electricity to this point of connection: Eskom or a licensed municipality?
2. Who owns the property, roof or carport, and who holds the electricity account?
3. What is the proposed generation capacity and connection voltage?
4. Will the plant operate in parallel with the grid?
5. Will it export, block reverse power flow, or wheel energy to another customer?
6. Does the project change the building, roof structure, fire routes, land use or heritage fabric?
7. Is the site leased, sectional title, mortgaged or subject to tenant and insurer conditions?
8. Which professional must design, certify and commission the system under the distributor's current rules?

The answers determine the approvals matrix. A standard rooftop project on an owner-occupied warehouse has a different route from a landlord-funded carport, a tenant PPA, a ground-mounted plant or a generator that will wheel energy.

The commercial approval stack

This is a screening table, not a universal legal determination. The distributor and appointed professionals must confirm which rows apply to the site.

Check the national and distributor capacity routes

NERSA's February 2026 clarification says a grid-connected embedded generation facility with installed capacity of 100 kW or less registers with the relevant distributor, while a facility above 100 kW registers directly with NERSA. The rule is based on grid connection and installed capacity, not only on export.

Public distributor material does not always use the same unit. Eskom's current SSEG information page describes its split using 100 kVA. kW and kVA are not interchangeable. Ask the distributor and NERSA to confirm the capacity basis and route for the proposed design in writing rather than converting the threshold yourself.

Larger embedded generation also has a more involved technical route. The Embedded Generation Resource Portal maintains a separate 2026 guide and application resources for municipal projects of 1 MW and larger. Connection voltage, network impact, export and wheeling can add complexity below or above that marker.

Gate 1: secure property and account authority

The person paying for the project may not control the roof or electricity account. Record:

• registered property owner;
• landlord, tenant and lease term;
• body corporate or homeowners' association authority where relevant;
• electricity account holder and point-of-delivery details;
• lender, insurer or bondholder consent requirements;
• roof, carport, plant-room and cable-route rights;
• rights of access for survey, construction and maintenance;
• responsibility for leaks, structural damage and reinstatement; and
• what happens when a tenant leaves, a unit is sold or the finance agreement ends.

Eskom's application requirements say property owners apply, subject to listed exceptions for certain entities, and tenants need the owner's consent for changes to the electrical plant. An applicant acting for another party also needs authority. A municipal process may use different forms, but the underlying mismatch still needs to be resolved.

For a PPA, lease or rent-to-own project, align the equipment ownership and access clauses with the property consent. The solar PPA guide explains the roof-right, early-exit and end-of-term questions that need legal review.

Gate 2: confirm the distributor and connection path

Use the supplier named on the electricity account. A site located inside a municipality can still be supplied directly by Eskom, and a nearby property may have a different distributor.

Ask the distributor to confirm:

• which SSEG or embedded-generation process applies;
• whether approval is required before installation;
• the accepted inverter and protection requirements;
• whether a grid or capacity study is required;
• the export or reverse-power-flow conditions;
• the professional registration and sign-off required;
• the meter and tariff change;
• application, quotation, connection and study charges;
• required agreements; and
• the evidence needed before switch-on.

Do not assume zero export removes the application. A system operating in parallel with the grid can still fall within the distributor's process.

Gate 3: submit a complete technical pack

The pack varies by distributor and project size, but a commercial application may include:

1. property, applicant and electricity-account details;
2. letter of authority, landlord consent or corporate resolution;
3. proposed generation and storage capacities in the units requested;
4. point of connection and connection voltage;
5. single-line diagram showing meters, isolation and protection;
6. site layout, panel arrangement and cable routes;
7. exact inverter, battery and protection schedules;
8. NRS 097-2-1 type-test evidence where applicable;
9. export, reverse-power-flow or wheeling arrangement;
10. protection settings and anti-islanding method;
11. transformer, fault-level and power-quality information where requested;
12. structural information and professional appointment;
13. proposed tariff and metering arrangement; and
14. application forms signed by the required parties.

The commercial project screening calculator identifies the likely assessment route from six early facts. The commercial site assessment guide then sets out the bills, interval data, electrical records, roof information and operating details needed before this pack can be finalised.

Gate 4: obtain permission before construction

The sequence matters. Some distributors issue a permission-to-install letter after accepting the application. That letter is not the same as commissioning approval to switch the system on.

The City of Cape Town's current embedded-generation authorisation process provides a clear example. It covers SSEG below 1 MVA and an EG route above 1 MVA and below 100 MVA within the City's supply area. The property owner, electrical contractor, installer and ECSA-registered professional use the online Energy Services application. The City issues permission to install, after which the system may be built but not switched on. The CoC, signed supplemental contract and professional commissioning report are then uploaded before the commissioning letter permits operation.

That is a Cape Town example checked on 23 September 2026, not a national sequence. Eskom and other municipalities have their own forms, thresholds and professional requirements.

For an Eskom-supplied commercial site, the embedded-generation application process can include a quotation fee, metering changes, network upgrades and agreements covering supply, connection and use of system. Eskom says connection work starts only after the quote is accepted, charges are paid and the relevant agreements are signed.

Gate 5: close the structural and site-specific approvals

Distributor approval does not prove that the roof can carry the array or that a new carport, plant room or ground-mounted system satisfies every site rule.

Screen the project for:

• roof condition, wind loading and structural capacity;
• waterproofing and roof-warranty conditions;
• fire access, isolation, signage and emergency response;
• carport, canopy, plant-room, trench or equipment-foundation approvals;
• zoning, land-use or building-plan implications;
• heritage restrictions;
• environmental triggers for larger or sensitive sites;
• servitudes and underground services;
• aviation, glare or radio-astronomy constraints where relevant; and
• occupational health and safety duties during construction and operation.

The national Energy One Stop Shop permitting tool can help larger projects screen for environmental and other permitting triggers. It does not replace advice from the relevant authority or appointed professional.

Ask each professional to state what is within their appointment. An electrical sign-off is not a structural opinion, and distributor approval is not planning approval.

Gate 6: finalise metering, tariff and contracts

The commercial model needs the same connection assumptions as the technical application. Confirm:

• whether export is allowed;
• whether a bidirectional or advanced meter is required;
• who supplies and pays for the meter;
• the import tariff after connection;
• the export rate and eligible energy components;
• fixed, network, demand and capacity charges that remain;
• the effective date of any tariff change;
• electricity supply, supplemental or use-of-system agreements; and
• whether wheeling or banking requires a separate process.

Cape Town says feed-in systems require an AMI meter at the customer's cost, while a non-feed-in system with reverse-power-flow blocking remains on its current tariff under the current published process. Eskom says legal connection requires an active electricity supply agreement and any supplementary agreements needed for SSEG, export or banking. These examples show why the financial model cannot assume a generic export credit or unchanged tariff.

The commercial solar cost guide explains how to keep connection, professional and metering work visible in the project budget.

Gate 7: install, test and obtain commissioning approval

Before switch-on, the project should complete the tests and submissions required by the accepted design and distributor. The close-out process may include:

• electrical CoC and test results;
• as-built single-line diagram and layout;
• equipment model and serial-number schedule;
• protection settings and anti-islanding test;
• inverter type-test evidence;
• embedded-generation installation or commissioning report;
• registered professional sign-off;
• structural completion evidence;
• meter installation and tariff confirmation;
• signed connection or supplemental agreements;
• distributor inspection where required; and
• written permission to connect, commission or operate.

Do not treat inverter energisation, Wi-Fi commissioning or a successful internal test as distributor approval. Keep the written close-out evidence with the asset records.

Gate 8: hand the approval pack to operations

The final pack should contain:

Any later increase in capacity, inverter replacement, export change or connection alteration may need distributor approval. Record who checks that requirement before modifications are ordered.

A practical responsibility matrix

Write the names, dates and dependencies into the project programme. A proposal that says only "SSEG included" does not show who applies, pays, corrects rejected documents or carries delay risk.

Approval checklist before proposal acceptance

• Electricity distributor and point of connection confirmed
• Property owner, roof rights and electricity-account authority confirmed
• Installed capacity and applicable distributor or NERSA route confirmed
• Export, non-export or wheeling arrangement stated
• Required application, study, meter, tariff and agreement identified
• Permission-to-install sequence confirmed
• Professional design, structural and commissioning appointments stated
• Building, planning, fire, heritage and environmental triggers screened
• Equipment and protection evidence listed
• CoC, testing and commissioning deliverables included
• Written approval required before switch-on identified

• Final handover pack and change-control owner specified

What finance, technical and legal reviewers need

Finance

Finance needs application, study, professional, meter and network-upgrade allowances, plus schedule risk and the tariff that applies after connection.

Technical and facilities

The technical team needs the accepted connection basis, drawings, protection, studies, professional scopes, commissioning plan, access and future-expansion constraints.

Legal, procurement and property

These reviewers need property rights, application authority, contract interfaces, delay allocation, liability, insurance, access, equipment ownership, reinstatement and evidence required for final acceptance.

Sources and review note

This guide was checked on 23 September 2026 against NERSA's February 2026 clarification, Eskom's SSEG and embedded-generation application material, the City of Cape Town's current online authorisation process, the Embedded Generation Resource Portal and the Energy One Stop Shop permitting tool. Requirements vary by distributor and project. Confirm the route with the electricity distributor, relevant authorities and appropriately registered professionals before installation.

Alumo provides its own assessment, design, finance terms, installation and warranties. The signed proposal should identify which approvals and professional services it includes.

Frequently asked questions

Does a commercial solar project need SSEG approval if it will not export?

Grid connection is the main issue, not only export. NERSA's February 2026 clarification says the registration requirement depends on the point of grid connection and installed capacity. The distributor may require an application and approved reverse-power-flow control for a non-exporting system.

Is an electrical CoC the same as distributor approval?

No. The CoC covers electrical installation work within its stated scope. Distributor authorisation covers connection and operation on that distributor's network. A commercial project can need both, along with professional commissioning evidence.

Can installation start before SSEG approval?

Only if the applicable distributor process allows it. Cape Town's current process issues permission to install before construction and a commissioning letter before switch-on. Other distributors use different sequences. Confirm the rule in writing before ordering or installing equipment.

Who should submit the commercial solar application?

The property owner or electricity-account customer remains central, while an installer or professional may prepare and submit technical information under authority. The project responsibility matrix should name who submits, pays fees, answers corrections and keeps the final approval.

Do rooftop panels need building-plan approval?

Not every rooftop array needs a building-plan application, but structural work, carports, plant rooms, heritage sites, fire requirements or other physical changes can trigger separate approvals. Ask the relevant municipal and appointed professionals to screen the actual scope.

What documents should be ready for a commercial approval assessment?

Prepare the electricity account, property and authority records, proposed capacity, export plan, single-line and site drawings, equipment schedule, roof information, supply and transformer details, and previous distributor correspondence. Start a commercial approval assessment with those documents ready.
