This order was only for two that were damaged in the last shipment. Out of 4 shipments I have always had some damage either glass (3) times or bent frames etc. It did not matter if a whole pallet stacked sideways or stacked parallel on the pallet. I highly recommend santan for solar panels since they will ship them at not cost to you.
Very new to solar but started purchasing items, not sure of the final specs of the whole system.

Lowes finally got the plastic caps in and working on putting thoses on. Started working on the panels.
Pulled so much wire since I went to 3 panels and now 3 of my midnite combiners are only have
full.

@kromc5 interesting array setup. is there a reason why you have a gap between each col. of panels? seems like you could fit more panels if each col. does not have that large space. Thanks

I think a closer spacing of the rails could provide better support in high winds. If that is ever an issue.
I would put rails at 25% and 75% locations under panels. There is probably a more accurate calculation considering rigidity of panel frame (deflection at middle between to rails vs. deflection of each unsupported overhang is probably less), but that would be my first-order estimate.

The steel pipes are 21 feet, so I thought it would help with wind loads to space them apart since I had the room. But there is not enouigh room for an extra row, that would have saved a bunch on the others if I could do that. They are spaced right at 9 inches apart, the panes are all 79.5 inches.

I will go measure them since how far off I am on those.
I think you are overthinking the issue. Appears you are using Ironridge purlins and 3" top and bottom cross pipes which are more than sturdy for any wind load. Check out ironridge's free design tool and you can confirm how many panels would fit given the length and width of the current hardware. I would not be surprised if your structure can support 20-30% more panels. That way you avoid any space wasting.

Thank you for that link this is how I did the design for everything, I did go way over as the design allows for 2 or 3 inch. When I bought the pipes they were way cheaper, all further installs will be with 2 inch.
I believe @Hedges is close to the mark but there are design specs printed on most panels that should be followed. I would avoid guessing and look up the specs., it is usually a "window" that should be followed, eg. 8-14" from edge. I think you will end up being surprised on the wasted space and how many additional panels your structure can support.
I really wanted to get an extra column but 3 panels are 19.87 feet, I tried many design ideas. I tried to measure how far over I could take them off each side but I thought it high winds could possibly damage them.

Got batteries in from Hayley, the batteries cosmetically are perfect, flat with no spacing, do dings etc. I will do a post in the battery section, I will test them for capacity and report back. Some of the caps fell off the terminals during shipping and asked for 50% refund. /j They also come with a limited edition post-it notes.

@kromc5 wow those look great! how many again & what was your cost?Got batteries in from Hayley, the batteries cosmetically are perfect, flat with no spacing, do dings etc. I will do a post in the battery section, I will test them for capacity and report back.

Since they were running older version of eve I bought 32, I think it was 123 per battery I can verify that tomorrow.
I was notified that they are having a sale starting this month. I will update with a graphed capacity, mostly like late evening today.
The panel twilight zone continues, RL carries came out to delivery the panels from santansolar and they did not load them on the truck. The driver was very nice, he's laughed and said he gets paid by the hour since it was 2 hours to get to me.
Panels were delivered with no damage, satansolar did an excellent job shipping them out quickly and free of charge.
Finished testing one of the batteries I purchased from Hayley almost hit 285ah.

Since I had been using one bank to test I worried about the second bank having a different soc, I did a top balance on both. Everything is now connected just waiting for the second back to finish coming down from the top balance. This is what the multi-string looks like in the toolkit, this is two 4p16s. Once the get close I had thought instead of flipping the large breaker I would do a test. using a few cables with automotive holders so I can test connecting the two batteries, I have a few 10/20/30 amp fuses and separate cables to do that with.

Also if anyone sees an issue with the way I'm connecting the batteries in post 457, one right above this one please let me know. I'm following hopefully correctly how batrium shows multi-string. I suspect it will be later tomorrow before they get close to each other.
Thank you
Thank you
