Grid-Tied, Hybrid & Off-Grid Solar Systems
There are three core ways to configure a solar system in South Africa. The right one depends on your budget, your electricity usage, and how much protection you need from load shedding. Here's how each works.
Grid-Tied Solar System
Maximum savings, lowest upfront cost.
A grid-tied system works alongside the municipal or Eskom grid without battery storage. Your panels power the property directly during the day and feed any surplus back, while the grid covers you at night.
How it works
Solar panels and a grid-tie inverter convert sunlight into electricity that runs your property in real time. When you generate more than you use, the excess can offset your bill where net metering or feed-in is available; when you use more, you draw from the grid seamlessly.
Benefits
- Lowest upfront cost
- Best return on investment
- Simple, low-maintenance setup
- Can offset bills via feed-in where available
Things to consider
- No backup during load shedding or grid outages
- Savings depend on daytime usage
Hybrid Solar System
Savings plus load-shedding backup.
A hybrid system combines a grid connection with battery storage, so you save during the day and keep essential circuits running when the grid goes down.
How it works
A hybrid inverter charges a battery bank from solar, and optionally the grid. Stored energy powers your property at night and switches over automatically during load shedding, keeping selected circuits live.
Benefits
- Keeps essential circuits on during load shedding
- Stores daytime solar for night-time use
- Balances cost and resilience
- Battery capacity can be scaled over time
Things to consider
- Higher upfront cost than grid-tied
- Batteries add maintenance and eventual replacement
Off-Grid Solar System
Total energy independence.
An off-grid system runs entirely on solar and battery storage with no grid connection, giving complete energy independence.
How it works
Solar panels charge a large battery bank sized to carry your full load through the night and cloudy days, often with a backup generator for extended low-sun periods. The system must be carefully sized to your exact consumption.
Benefits
- Complete independence from the grid
- No utility bills
- Ideal where grid access is poor or absent
Things to consider
- Highest upfront cost
- Requires careful load sizing
- May need a backup generator for low-sun periods
