Here are a couple of great options for 6 x 550W solar panels: The best deal would be a Pack of 12 550W Solar Panel TW Mono Crystalline Half Cell 144 Cells for R56,280. This works out to R4,690 per panel, giving you an excellent bulk purchase price. These panels are high quality mono crystalline panels with 144 half-cut cells each. Alternatively, you could purchase 6 panels individually of the 550W Solar Panel TW Mono Crystalline Half Cell 144 Cells for R4,990 each, totalling R29,940. While a bit more expensive per panel, this allows more flexibility if you need panels at different times. Both of these options are tried and tested brands. Let me know if you need any other details!
