Solar panels, inverters and batteries are now one of the most common electrical jobs in Benoni. These are electricians who list solar or backup power work, and what to check before you sign.
Questions to ask installers
- Is the installer a registered electrician who will issue a CoC for the installation?
- Which inverter and battery brands do they use, and what warranties come with them?
- How did they size the system: from your actual electricity use, or a standard package?
- Will they handle registration with the municipality if required?
- Who do you call if the system fails, and how quickly will they respond?
Paperwork
- An electrical CoC for the installation
- Municipal registration of the system where required. Check with the installer for Ekurhuleni's current requirements.
- Your insurer may want the installation details and CoC

Systems are quoted very differently. Compare the inverter size, battery capacity (kWh), number of panels and warranty, not just the total price.
Frequently asked questions
What size inverter do I need?
It depends on what you want to run at the same time. A typical home backing up lights, plugs, Wi-Fi, TV, fridge and gate motor often starts at 3–5 kW. See our inverter and battery backup guide.
Can I start with an inverter and battery and add solar panels later?
Yes, if you choose an inverter that supports panels. Many Benoni homes start with backup and add panels later.
Do I need to register my solar system with the municipality?
Grid-connected systems with panels may need registration under the City of Ekurhuleni's rules for small-scale generation. Your installer should advise you, and the system needs an electrical CoC.
How long do lithium batteries last?
Good lithium (LiFePO4) batteries are typically rated for thousands of charge cycles and come with multi-year warranties. Ask for the warranty terms in writing.
