Is that the racking? I need to add 8 more panels this spring. I was trying to decide how I was going to do the racking. This array was installed 9 yrs ago. I restrung it and pulled new wire when I added the Sol Ark in September. I have 2x9 (x2) and an 8 panel string. When I finish I’ll have 2x8 for my 3rd MPPT. Any suggestions would be appreciated. It has taken some pretty good wind loads over the past 9 yrs. I thought it was overkill when they augered down 6 ft in the first place. But probably not. I’m thinking of adding 4 poles for the rack extension and then building off that. I could probably get away with adding 2 poles and build off the end of my present array.Unirac ULA, the newer aluminum brackets. I have both kinds.
You haven't included X direction diagonals. No earthquake concerns? At least one should help stiffen against vibration in the wind.
