Solar installer's certification documents laid out on a table

"Certified installer" appears on almost every solar company's homepage in South Africa. It's a claim, not proof — and the gap between a company that genuinely maintains its certifications and one that lists a badge it earned once and never renewed is exactly where problems tend to surface later, usually at the worst possible time: when something goes wrong and you need to make a warranty or insurance claim.

Certification Isn't One Thing

"Certified" can refer to several different, non-interchangeable things:

  • Individual electrician registration — the actual person doing the wiring being registered to issue a Certificate of Compliance
  • Product-specific training certificates from panel, inverter, or battery manufacturers, confirming the installer has been trained on that specific equipment
  • Industry body membership, which typically requires meeting certain standards to join and stay listed, but membership tiers and requirements vary between bodies
  • Company-level accreditation with a particular equipment brand, which says more about sales volume than installation quality in some cases

A company can genuinely hold one of these and not the others. Asking "are you certified?" gets you a yes almost every time. Asking "certified by whom, for what, and can I see the current documentation?" is what actually separates the companies with something to show from the ones repeating a marketing line.

What to Actually Ask to See

Before committing, it's reasonable to request:

  1. The individual electrician's registration details for whoever will sign your Certificate of Compliance
  2. Manufacturer training certificates for the specific inverter and battery brand they're proposing, not just "we're trained on solar"
  3. Proof of current public liability insurance, which protects you if something goes wrong during installation
  4. References from at least two completed jobs in the last year, ideally ones you can actually visit or call

A company confident in its credentials will produce these without friction. Reluctance, vague answers, or "we'll send that over" that never arrives is itself useful information.

Why This Matters More for Solar Than General Electrical Work

Solar and battery systems combine electrical work with equipment-specific configuration — inverter settings, battery management system configuration, and export/import metering setup — that general electrical certification alone doesn't guarantee competence in. An installer can be a properly registered electrician and still be inexperienced with a specific inverter brand's quirks, which is where product-specific training becomes relevant on top of the base electrical registration.

Certification and Compliance Are Related but Different Checks

Checking an installer's certifications is about their competence and standing going in. Getting a proper Certificate of Compliance for your specific installation is the documented proof that the actual work done at your property meets the required standard. Do both — one doesn't substitute for the other.

Where to Start Looking

Rather than vetting every claim on every installer's website from scratch, browsing installers already vetted on ADEO gives you a shortlist where this groundwork has been done. It's still worth asking the questions above directly — vetting on entry doesn't guarantee every credential stays current forever — but it narrows the field considerably.

Frequently Asked Questions

Is a manufacturer training certificate the same as an electrician's registration? No — one confirms familiarity with a specific product, the other confirms legal authority to sign off electrical work. A credible installer should be able to show both where relevant.

How do I verify an electrician's registration is genuine and current? Ask for their registration number and cross-check it against the relevant regulatory body's public register, rather than accepting a certificate image alone.

Should I be worried if an installer has only been trading for a year or two? Not automatically — newer companies can be excellent, especially if key staff have longer individual track records. Focus the check on individual certifications and references rather than company age alone.
