Calculate system temperature loss, 4.38 kW ÷ 0.88 = 4.98 kW (correct) : ) 5. Calculate system derate, 4.98 kW ÷ 0.95 = 5.24 kW (correct) : ) 6. Calculate inverter loss, 5.93 kW ÷ 0.955 = 5.26 kW (wrong) ?? (5.93 kW divided by 0.955 = 6.21 kW) ; ( Therefore, according to this, I would need a 5.26 KW DC rated PV system??? How did you get that answer? 5.26 KW DC I think you might have taken your glasses off when you did this last equation. 4. Calculate system temperature loss, 4.38 kW ÷ 0.88 = 4.98 kW (correct) : )
