Service assessment and practical solutions

Separate installation complete from ready to energise

Panels and an inverter may be physically mounted yet the system still requires safety testing and the relevant utility authorisation. In the City of Cape Town supply area, the commissioning requirements include appropriate sign-off and records before the system may be switched on. We ask whether permission to install exists, what equipment was installed and who has responsibility for the commissioning documents. A handover inspection should identify missing evidence rather than assume a working display proves legal or electrical completeness.

Review the protection and as-built records

A meaningful handover typically records equipment identity, cable routes or diagrams, isolation arrangements, required labels and relevant protective-device tests. Changes made during installation need to be reflected in the documents. We distinguish a visual check from tests that must be performed by the properly authorised person. If a previous contractor completed the work without usable records, the scope of reconstructing diagrams and conducting the necessary checks should be stated rather than promised as a simple certificate exercise.

Demonstrate normal operation and safe isolation

Owners should understand what the inverter indicates in normal sunlight, how the battery is used and what an ordinary grid failure looks like for the configured system. It is also important to know which equipment to avoid touching and which isolators are intended for qualified service personnel. We can help define the commissioning demonstration and the information that should be handed over. Incorrect battery settings or unsupported modes should not be adjusted casually to make a graph appear more impressive.

Leave a serviceable record for the next technician

The handover pack should retain equipment serial numbers, warranties, installer details, monitoring access ownership, approved drawings and applicable authorisation letters. These become valuable when a battery is replaced, a roof is repaired or the property changes hands. Where defects remain, they need an agreed corrective work list and independent retesting as appropriate. We do not treat missing authorisation as an administrative formality that can be ignored after the physical installation is complete.

Recognise the situation

Common enquiries and what changes the job

Installer has left but system is not signed off

A separate documentation and technical assessment may be needed before commissioning.

New owner cannot find the solar records

Recover equipment and authorisation information before changing the installation.

System has been upgraded without a revised diagram

Modified circuits and equipment should be accurately reflected in the required completion documents.

Before booking

Information that helps define the work

Supply the available approval correspondence, single-line diagram, equipment schedule and installation date. Do not power an unauthorised system for demonstration.

Identify who is responsible for final electrical sign-off and whether you need a defect report, owner demonstration or full commissioning coordination.

Quotation scope

What affects the cost and work programme?

Availability and accuracy of existing records
Equipment and protection inspection scope
Qualified testing and sign-off roles
Utility permission and commissioning status
Owner handover and corrective items

Where applicable in the City of Cape Town electricity supply area, new solar PV/battery systems and relevant system changes must follow the City authorisation process. Professional sign-off and suitable approved inverters are important requirements; never activate an unauthorised modified system.

For applicable local requirements, see the City of Cape Town: commissioning and permission to operate. We confirm the current conditions before proposing work.

Useful next step: Property transfer compliance → Keep water and electrical compliance requirements separate and organised.

Frequently asked questions

Solar PV Commissioning & Handover Checks: customer questions

Is a powered-on inverter proof the system is compliant?

No. Electrical tests, required documents and applicable municipal authorisation are separate matters.

Can a different contractor review another installer’s work?

A suitably qualified professional can assess it, but the extent of review and responsibility must be clearly defined.

What should the homeowner receive at handover?

Usually the applicable compliance and approval documents, system diagrams, equipment details, warranties and basic operating instructions.
