The Hyundai SG Series are the slightly smalller 350W model while the VG series is a larger 400W version. Both have shingled cells and come with the same 25 year product warranty. In my experience, they are a good reliable choice and look great.
The other options are all quite good but my personal pick would be - 6.66KW - 18 x Trina Honey M solar panels + Sungrow SG5K inverter = $5740
Remember it also depends on the installer or retailers reputation.
