CALCULATIONS
8.745kW System Size (STC)
• 33 Canadian Solar CS6K-265M solar panels @ 265 watts
• 33 integrated SolarEdge P300 Optimizers
• 1 SolarEdge SE7600A-US inverter(2 strings of 16/17 modules/optimizers)
• Fixed array tilt angle: 22.62°
• Array azimuth: 120° (where 180° is south)
• Estimated annual power production: 11,778kWh
Maximum PV System Voltage: 690.7
Voc = 37.7V/module
37.7V x 1 module= 37.7V
Temperature correction factor 690.7(A)
Temperature Coefficient (Voc) = -0.31/°C
(-65C° x (-.0031C°)) = .2015%
((.2015% x 37.7V)x 1 panels) + 37.7V=45.1V
Maximum PV Source Circuit (String) Current: 690.8 (A)(1)
Ise/Imax= 15A
15A x 1.25 = 18.8A
Maximum PV Output Circuit(Array) Current: 690.8 (A)(2)
Max Input for SE7600A-US =23A
Inverter Output Circuit Current: 690.8 (A)(3)
32A @ 240V
