Service assessment and practical solutions

Roof wiring needs protection against more than rain

Solar cable routes sit among hot roofs, metal edges, wind movement and ultraviolet exposure. Damaged insulation, poorly supported loops or unsuitable penetrations can create electrical and water-entry problems over time. We begin with safe observations such as intermittent generation, visible dangling cable or damaged clips. Do not pull on wiring or touch exposed conductors to confirm a fault. The assessment should cover routing, mechanical protection, strain relief, water ingress and compatibility with the installed PV design.

Connector compatibility and termination quality

PV connectors are engineered electrical components, not general-purpose plugs. Components that look similar may be incompatible across manufacturers or series, and poorly made terminations can heat under load. A repair must use correctly rated, matched products and tools under manufacturer instructions. We inspect the associated cable and connection condition, not only the visibly discoloured connector. If multiple connectors were installed using the same unsuitable method, the quotation may identify additional inspection work rather than guaranteeing that one replacement fixes every fault.

Testing the affected string and cable run

An inverter warning might originate from the panels, their string wiring, protection devices or the inverter input. Qualified personnel can assess the relevant circuit using procedures suitable for hazardous DC voltages. We distinguish damaged cable replacement from reconfiguring a string: changing module numbers, input layout or voltage design can alter system requirements and approvals. Repairs should leave cable routes supported and accessible for future inspection, with protective equipment and relevant tests completed in the agreed scope.

Cape Town rooftops and record keeping

Coastal wind and exposure can worsen an already loose cable route, while roof repairs can displace supports and compromise penetrations. We ask whether the problem followed storms, roof work or a recent panel addition. Safe external photos, installation diagrams and inverter error history can help plan access. If the configuration changes, we assess the City’s solar authorisation requirements before energisation. We will not describe photographs of other contractors’ installations as Katawa completed projects; any project evidence used must have verified provenance.

Recognise the situation

Common enquiries and what changes the job

PV cable hangs beneath panels

Support and abrasion risks need qualified assessment; do not attempt roof access or cable handling.

Connector appears melted

A poor contact, incompatible component or other fault may be involved. Do not unplug the connection.

Intermittent output after a storm

Loose routes, water ingress and string electrical issues are all possibilities requiring tests.

Before booking

Information that helps define the work

Provide inverter model, any original wiring diagram, safe photographs from ground level and the approximate roof type.

Let us know whether roof waterproofing or panel mounting was altered recently; roof repair and electrical repair scopes should be distinguished.

Quotation scope

What affects the cost and work programme?

Rooftop access and fall-protection requirements
Cable type, length and connection compatibility
Extent of damaged terminations or abrasion
Testing and protection equipment needs
Effect on approved PV configuration and paperwork

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.

Frequently asked questions

Solar PV Cable & Connector Repairs: customer questions

Can two PV connectors that fit together be used?

Physical fit does not establish electrical or manufacturer compatibility. Correctly matched products and installation tools are required.

Can I cover a damaged cable with insulation tape?

An exposed or compromised PV cable requires professional assessment. A makeshift wrap is not a safe substitute for compliant repair.

Why did performance fall after roof work?

Wiring or mounting may have shifted, but inverter data and a safe inspection are needed before identifying the cause.
