Solar Installation in Gauteng

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 Gauteng is your supply authority. 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.

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.

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 Gauteng land somewhere between 5 kW and 10 kW, but we would rather measure than guess.

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 your supply authority.

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.

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.

Solar on its own stops producing at night and legally has to shut down during an outage unless it is designed for it. If backup through outages is your priority, you want a hybrid system with a battery — which is what most of our Gauteng customers choose.
