I am looking at purchasing a 4KW system and worked it down to two options:
a) SUNPOWER E19 318 W
4.45KW: 14 x 318W panels / SMA SB 5000TL inverter
b) Conergy Power Plus 230M
4.2KW: 20 x 230W / AUROA PVI-5000-OUTD-AU inverter
Does anyone have any options on the two options, is there any concerns regarding the SUNPOWER panels.
