Hi all.
I am looking at:
Qty 18 LG 330N1C-A5 (330W) solar panels with SolarEdge P400 Optimizers
SolarEdge HD Wave SE5000H-US Inverter with 25 year warranty
SolarEdge ModBus (consumption) meter
Solar Edge WiFi Kit
Main Electrical Panel Upgrade
Unirac Solar Mount Racking
10 of the panels will be on a south-facing roof with a 23 degree tilt
8 of the panels will be on a east-facing roof with a 23 degree tilt
I realize that the SolarEdge SE5000H-US can handle the theoretical max of 330 x 18 = 5940W on its inputs, but anything above 5040 watts (21A x 240v) will be lost, right?
Using pvwatts, I generated the hourly data for the two strings and then processed the numbers. Using the STC rating of 330W with an 8% system loss, I could theoretically see 189 hours with over 5040 watts of production the first year. Using LG rated degradation of 0.55%, that drops to 135 hours the second year, 117 hours the third year, etc,:
year 1: 189 hours, 38.333 kWh lost
year 2: 135 hours, 21.603 kWh lost
year 3: 117 hours, 17.967 kWh lost
year 4: 99 hours, 14.895 kWh lost
year 5: 93 hours, 12.121 kWh lost
year 6: 76 hours, 9.752 kWh lost
year 7: 65 hours, 7.768 kWh lost
year 8: 55 hours, 6.040 kWh lost
year 9: 44 hours, 4.609 kWh lost
year 10: 33 hours, 3.520 kWh lost
The maximum output is happening on March 27 during the noon hour, where the first year I could see 5815 watts produced.
I am trying to decide if I should tell the installer that I want to wait for the SolarEdge SE6000H-US to avoid this clipping. The SE6000H-US is not that much more than the SE5000H-US, but I might have to wait an extra month to get it.
Am I am understanding the situation correctly? Or is the hourly data from pvwats too granular to use for this kind of calculation?
Anyone have any thoughts or advise?
Thanks,
John
