We install solar across Johannesburg CBD as electrical contractors first and solar installers second. That matters: the panels are the easy part. What determines whether your system is safe, legal and insurable is the DC protection, the earthing, the board work and the certification — and that is electrical work.
Known for the inner city — high-rise commercial and residential blocks, converted industrial buildings and dense mixed-use precincts, much of it on ageing distribution infrastructure, Johannesburg CBD keeps our teams busy across every kind of installation from single plug points to three-phase distribution.
Because Johannesburg CBD falls under City of Johannesburg and is supplied by City Power, anything that touches the connection itself follows their process and their timelines. We work to those rather than promising you turnaround times that are not ours to give.
Solar Installation services we provide in Johannesburg CBD
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 CBD
Extended homes and added circuits
Homes in Johannesburg CBD have typically grown over time — rooms added, outbuildings converted, backrooms let out. Each addition tends to be spurred off whatever circuit was closest, so the original board ends up carrying loads it was never designed for. The repair is usually less about the last thing that failed and more about redistributing the installation sensibly.
Ageing risers and common-property boards
The distribution infrastructure in older Johannesburg CBD buildings is frequently the least-maintained part of the property, because no individual owner feels responsible for it. Rising mains, common-area boards and emergency lighting are exactly where a building inspection tends to find problems, and exactly where insurers look after a fire.
Ageing wiring and original distribution boards
A large share of the housing stock in Johannesburg CBD predates modern wiring practice. We regularly open boards here that still have rewirable fuses, no earth leakage protection, or earth conductors that were never properly bonded. Insulation on older cabling also goes brittle with age, which is why so many "sudden" faults in Johannesburg CBD turn out to have been decades in the making.
The compliance side, explained plainly
Two documents decide whether a solar or inverter installation in Johannesburg CBD 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 CBD — your questions answered
Do I need to register my solar system in Johannesburg CBD?
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 CBD 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 CBD 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.
