What Is the Cheapest Solar System?
Here’s the truth:
The cheapest system upfront is often the most expensive long-term.
💸 Entry-Level “Cheap” Solar Options
Basic Backup System (No Panels / Minimal Panels)
- Price Range: R25,000 – R60,000
- Includes: Inverter + battery
- Purpose: Backup during load shedding only
- Limitation: Does NOT significantly reduce electricity bills
Low-Cost Grid-Tied Solar (Minimal Battery)
- Price Range: R60,000 – R100,000
- Includes: Panels + inverter (little or no battery)
- Purpose: Reduce daytime electricity costs
- Limitation: Limited functionality during outages
⚠️ The Hidden Cost of Cheap Systems
Many Soweto clients initially consider cheaper installations—but quickly run into problems:
- Poor-quality panels degrade faster
- Inverters fail under load
- No proper system design
- No after-sales support
This leads to reinstallation costs, downtime, and frustration.
