Quick answer: 550W is the default choice for most residential systems due to value and availability. 550W panels have become the standard for South African residential installations. They use half-cut cell technology for better performance in shade and higher efficiency than older 400W panels.

Why 550W Panels?

Advantages of 550W panels:

  • More power per panel = fewer panels needed
  • Half-cut cells = better shade performance
  • Latest technology = higher efficiency (21%+)
  • Best value: similar price to old 400W panels
  • Standard size fits most roof types

550W Solar Panels FAQs

9-10 panels for a 5kW system (5000W ÷ 550W = 9.1 panels). Most installers use 10 panels (5.5kW) to account for efficiency losses and provide a buffer.
For a typical South African home: Essentials only (5kW system): 8-10 panels. Average home (8kW system): 14-16 panels. Large home (10kW+ system): 18-22 panels. Calculate based on your monthly electricity usage and roof space.
Quality solar panels last 25-30 years with minimal degradation (0.5-0.8% per year). After 25 years, they still produce 80-85% of original capacity. Tier-1 brands like JA Solar and Canadian Solar offer 25-year performance warranties.
