Overberg Solar designs and installs solar, inverter and battery systems for homes, farms and businesses across the Overberg. We size every system on your actual electricity bill and how you use power, so you get the backup hours you need without paying for panels you do not.
Our own team does the installation, usually in one to two days, and every job ends with an Electrical Certificate of Compliance, the municipal registration where it applies, and a walk-through of the monitoring app.
WhatsApp a photo of your bill and your roof to get a straight answer on what solar would do for you.
Pieter van Wyk · Owner and lead installer
WhatsApp a recent electricity bill and a photo of your roof. That tells us your usage and what will fit before anyone visits.
We measure the roof, check the DB board and design a system sized for how you actually use power, with backup hours you can rely on.
Panels, inverter and batteries installed by our own team, usually in one to two days, with cabling and mounting done to SANS standards.
Electrical Certificate of Compliance, municipal registration where required, and a walk-through of the monitoring app so you know what your system is doing.
“They sized the system on our bill instead of selling us the biggest one. Backup has carried us through every outage since.”
“Packhouse array was up in four days without stopping our season. Paperwork handled.”
“Clean installation, neat cabling, and they showed us the app properly before leaving.”
It depends on what you want to keep running and for how long. A typical household that wants lights, Wi-Fi, TV, fridges and a few plugs through a four-hour outage needs roughly a 5 kW inverter with 5 to 10 kWh of battery; adding panels then cuts the daytime bill. We size on your actual bill, not a rule of thumb.
For backup only, an inverter and battery is enough and costs less. Panels are what reduce the bill and recharge the battery during the day, so most people who can afford it add them at the start or later.
Not usually on a standard home system; they draw too much. Most installations leave the geyser, stove and oven on the grid and put the rest of the house on backup. A solar geyser or heat pump is the better way to cut water heating costs.
Yes. Any change to your electrical installation, including an inverter, needs an Electrical Certificate of Compliance signed by a registered person. Insurers ask for it after a claim and it is required when you sell.
In most municipalities, yes, and grid-tied systems certainly. The rules differ by area; we handle the small-scale embedded generation paperwork as part of the installation where it applies.
A standard home system takes one to two days on site once the equipment is in stock. Larger commercial arrays are scheduled by phase so the business keeps trading.
