The Electrical Contractors’ Association of South Africa (ECA SA) has intensified its warning against allowing Electrical Testers for Single Phase to sign off on solar photovoltaic installations, while also calling for stricter verification of installer credentials across the market.
The association maintains that solar PV systems and DC coupled technologies fall outside the technical scope of single-phase testers. It cautions that improper certification not only introduces significant safety risks but may also invalidate insurance claims and expose project owners to legal liabilities.
Under current regulations, only registered Installation Electricians or Master Installation Electricians are authorised to issue a Certificate of Compliance for solar PV systems. Although Electrical Testers for Single Phase may assist under supervision, they are not permitted to certify such installations.

This position is supported by major supply authorities including Eskom and the City of Cape Town, both of which prohibit single phase testers from approving PV systems.
All installations must comply with SANS 10142 to ensure legal validity, particularly in property transactions. Grid tied systems must also be registered as Small Scale Embedded Generators with local municipalities to avoid penalties and ensure compliance.
The ECA SA highlights that non compliant sign off can result in denied insurance claims, illegal system operation and heightened safety risks, including fire hazards, voltage instability and back feeding into the national grid.
In addition to certification concerns, the association is urging developers, businesses and homeowners to actively verify the credentials of solar installers before project commencement.
To verify a solar installer in South Africa, clients should request the installer’s registration card issued by the Department of Employment and Labour as well as a valid wireman’s license. These credentials should then be confirmed with the relevant Provincial Chief Inspector to ensure authenticity and scope of qualification.
Installers must be registered electrical contractors and are legally required to provide proof of registration upon request. Clients are advised to confirm that the installer holds the appropriate license classification, such as Installation Electrician or Master Installation Electrician, aligned with the complexity of the work.
Further verification should include confirming registration with the Bargaining Council for the Electrical Industry, which governs compliance within the sector. As an additional layer of assurance, project stakeholders may check whether the installer is accredited under the SAPVIA PV GreenCard programme, an industry backed quality and compliance initiative.
The ECA SA is currently engaging with the Department of Employment and Labour regarding interpretations that may suggest broader sign off authority. However, it maintains that ensuring public safety and protecting infrastructure requires strict adherence to established qualification standards and verification processes across South Africa’s rapidly growing solar sector.
