600W Solar Panels FAQs

They provide more output per panel, but are larger. They are best for large systems where panel count matters more than panel size.
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.
