Frequently Asked Questions
Is solar worth it in South Africa in 2026?
Yes. With Eskom tariffs at 271c/kWh and rising 8-12% annually, most South African solar systems pay for themselves in 4-6 years, then generate free electricity for 20+ more years.
How much can I save with solar over 10 years?
A typical 3-bedroom home using 600 kWh/month can save R50,000-R100,000+ over 10 years with a well-sized solar system. The actual savings depend on your usage, roof orientation, and system size.
What is the payback period for solar in South Africa?
Most South African solar installations pay back in 4-6 years. After payback, the system generates free electricity for its remaining lifespan (25+ years for panels, 10-15 years for LiFePO4 batteries).
Do I need a battery to save money with solar?
No. A grid-tied system without battery still saves you money by offsetting your electricity bill during the day. Batteries add R35,000-R55,000 to your system cost but provide load shedding backup.
