A solar installation in Johannesburg South has to satisfy three parties: you, City of Johannesburg, and your insurer. We design and install with all three in mind, and we hand over the documentation to prove it.
Johannesburg South is a settled band of mid-century family suburbs on the southern ridges, with strong neighbourhood retail and a large stock of homes still running original distribution boards. That mix is what makes the electrical work here so varied — and why we keep teams working this area rather than sending someone across Gauteng.
Johannesburg South sits within City of Johannesburg, with City Power as the supply authority. Any work that changes your connection — a capacity increase, an embedded generation system, a new connection — goes through them, and we prepare the documentation that process requires.
Solar Installation services we provide in Johannesburg South
Consumption-based system design
We work from your actual usage profile — bills, tariff and load pattern — to size panels, inverter and battery. No guessing, no one-size-fits-all packages.
Grid-tied solar
Offsets your daytime consumption and cuts your bill. Requires SSEG registration with your supply authority.
Hybrid solar with battery backup
The most popular option in Gauteng: solar by day, battery through outages, grid as the fallback.
Off-grid systems
For smallholdings and properties with poor or no supply — sized with real autonomy margins, not best-case numbers.
Inverter & battery installation
NRS-compliant inverters, lithium battery banks, correct DC and AC protection, isolation and labelling.
Mounting & roof work
Rail systems suited to your roof type, with penetrations correctly sealed and cable runs protected from UV.
Electrical COC for the installation
A Certificate of Compliance is legally required for a solar installation regardless of its size. We test, certify and hand over the paperwork.
SSEG / municipal registration support
Grid-tied systems must be registered with your supply authority. We prepare the documentation — single-line diagram, inverter certificates, COC — and guide the application.
What we see in Johannesburg South
Installations that have outlived their design
The wiring in much of Johannesburg South was designed for a household that had a stove, a geyser and a television. It is now running heat pumps, pool equipment, home offices, backup systems and a dozen always-on devices. Nothing has failed exactly — it has simply been asked to do a job it was never specified for, and the distribution board is usually where that shows first.
Loads that punish a weak connection
Motors, compressors, welders and refrigeration plant in Johannesburg South draw hard on start-up and expose every marginal termination in the installation. A connection that is merely tight enough will survive a domestic load for years and fail on a factory floor in months, which is why thermal scanning under load finds problems that a visual inspection never will.
Compliance that someone will eventually ask for
Landlords, insurers and lease renewals in Johannesburg South all eventually ask the same question: where is the current Certificate of Compliance, and does it cover the work the tenant did? Getting that documented while the premises are trading normally is considerably cheaper than assembling it under pressure after an incident.
The compliance side, explained plainly
Two documents decide whether a solar or inverter installation in Johannesburg South is legal, insurable and safe to leave running. Most of the complaints we are called in to fix come down to one of them being missing.
An electrical Certificate of Compliance
Required for every solar or inverter installation regardless of size, because connecting one alters your electrical installation. It is also the first document an insurer asks for after a fire or lightning claim. Only a registered person may issue it, and only after testing the installation.
SSEG registration with City Power
Any system connected to the grid — even one that never feeds power back — must be registered as small-scale embedded generation with your supply authority. Registration needs a compliant inverter, a single-line diagram and your COC. A genuinely off-grid system with no grid connection does not need registration, but still needs a COC.
Municipal fees, timelines and any registration amnesties change regularly. We confirm the current position with City Power as part of every quote rather than quoting you last year's rules.

Solar Installation in Johannesburg South — your questions answered
Do I need to register my solar system in Johannesburg South?
If it is grid-tied — connected to the supply in any way, even without feeding back — yes. Small-scale embedded generation must be registered with your supply authority, which in Johannesburg South is City Power. Registration requires an electrical COC, a compliant inverter and a single-line diagram. Genuinely off-grid systems with no grid connection do not need SSEG registration, but still need a COC.
Does a solar installation need a Certificate of Compliance?
Yes — every solar installation needs an electrical COC regardless of size, because it is an alteration to your electrical installation. This is also the first document your insurer will ask for after a fire or lightning claim.
What size system do I need?
That comes from your consumption, not your roof. We look at your bills and load profile and size the array, inverter and battery to fit how you actually use power. Most homes in Johannesburg South land somewhere between 5 kW and 10 kW, but we would rather measure than guess.
How long does an installation take?
A typical residential system is installed in two to four days on site. The compliance side — COC, documentation and SSEG application — runs alongside and the approval timeline depends on City Power.
Will solar cover my whole house?
It can, but the honest answer for most properties is that it should not have to. Covering every load including geysers, pool pumps and electric heating gets expensive fast. We normally aim at the loads that give the best return and show you the numbers for going further.
Can you take over a system someone else installed?
Yes, and we are asked to do this often. We inspect what is there, test it, tell you plainly what is wrong and quote the remedial work needed to make it safe, certifiable and registerable.
