can you backfill behind the array with, dirt? seems to be plenty around, somebody must have a skid steer or tractor.

How many empty shipping containers are in the world right now. I would think most wind would blow through this laterally. Uplift is what I am worried about

No you're right, it hit's 100F here in summer, asphalt temps can get hot. It's faded, but still. Good call. I should spread the weight out a bit...

this should have been obvious to me, i am powering on inverter 1 for the first time tomorrow and would have been surprised. now i have 12 more hours to let that sink in, thank you. so you are already doing it, with some minor issues. thanks for sharing.

Yea, sorry I'm all over the place with the ideas. used shipping container(s) is still primary path. i am getting my inverter/batteries setup this weekend (this project was battery backup solution before solar) and then will pull the trigger on container 1 shortly after. I already sourced a...

There's no harm in confirrming that's what the OP is really working with, or mentioning he could be mistaken. 200 amp service is 100 amps on each leg. He says he has (2) 50 amp 240 circuits is (4) 50amp breakers run to the other side of the house. So the unused circuit is rated to max out...

I am looking to build an array in a small parking lot. it will only be in service 2-3 years, and i don't want to disturb the pavement. the top is 27.5ft x 11.5ft, with panels almost flat roughly 8.5ft above ground. it will be pitched slightly but only for runoff reasons. Certainly classified...

There isnt a wind break to the sides, but there is a concrete building behind it that will create uplift. Which leads me to my next point, that the structure should be similar to a deck from a footing requirement, which is why I am curious how much uplift such footings can counter. I have seen...

2 way tilt, 4 way might be hurting search

That's kind of what I was thinking, I have a 14ft box trailer parked next to this and it weighs 2200lbs. If we are talking wind that would blow over a box trailer, I am 5x more concerned about the trailer. Those diagonal braces need to be longer. I dont want to lose the ability to park cars...

It wasn't advertized when he asked, I had it in a quote from them. They have since advertized free shipping on the site.

Thanks for the followup. At least if you add solar (or maybe you did) it will be easy to move those 80% of loads over to the inverter sub panel.

I should be able hookup 90kW of panels mounted a single 20ft shipping container according to this.

What does the front look like? Datasheet? Specs? Price? I am super curious why you visited the factory. Did you take any photos? Are you looking to import them?

i was focusing on things with a built in spring loaded covers, but I suppose a screw on cap is sufficient, using a receptacle where I provide the enclosure. there's tons of things on Digikey also for that route. thanks

I live 1 exit away. If we get over a foot of snow, I will also be concerned about power lines being down and I will be there clearing the snow off to be ready for the sun.

you mean in the new garage (i have 24 feet in that direction)

Thank you. I know there's more to this as a whole but this is very helpful for perspective on possible solutions.

1. I havent powered iton yet, but I would email them. They will want to help you so you buy more. I will be in the same boat when I buy 2 more, I will email them also. 2. I have to check the manual but I dont think our units need the loopback parallel cable. That might be an issue...I would...

I am usually all about having extra gear if I get it cheap for backup/friends/future projects but I dont think I can find a home for an extra 15 panels right now unfortunately.

I can connect the legs. If you mean the big 3500lb blocks, I think you are suggesting 21,000lbs of weight. If the panels have 12,000 of lift at 120mph, why 21,000lbs of weight? I dont see 100mph winds happening here, and if there is there will be dozens of small dumpsters floating by like...

The SRNE batteries look nice. We are able to purchase their inverters on ali, but not the batteries. No distributors for us either. Does anyone know if anyone is rebranding them yet or how to get them in the USA? https://www.srnesolar.com/product/Storage-Battery.html#pro7

i moved on from the pergola for cost/ labor solving wind load. snow would have been easier to solve but never got there.

Update: it was in fact too good to be true. They had 800 panels needing repair and are almost done replacing connectors and recertifying them so installers gaurantee their work.

As long as the panels and unistrut staying attached with cables to the weights did not fly around and cause damage to other property, I will take that $2000 bet (value of my array and structure) any day of the week as we will never see that kind of wind in this location in 3 years.

I can't help but point out you suggested the blocks be attached to rigid structure, possibly the base. I was partially satisfying that with the rigid cinder block wall, but with less weight.

I am considering utilizing the roof of our box trailer to mount 6 panels, 370w each all in series. considering the inverter and batteries will NOT be in the trailer, wiring from the trailer would be the PV direct to the structure roughly 210 vdc 11amps. I don't love the idea of...
