diy solar

Very new to solar but started purchasing items, not sure of the final specs of the whole system.

Is the fabric UV resistant?

I previously used grey non-woven under bark. On a slope, wind and what not moves the bark and exposed fabric shreds after sun exposure.

I recently bought black woven "20 year sunlight resistant", the stuff you see as construction fences and the like.
It it weakening and shredding in a couple years. I think it is 20 year if covered and somewhat sunlight resistant.
I was suspicious about polypropylene, UV coated. Polypropylene is the stuff of blue tarps, and not sunlight resistant.

There are plastics which will last a couple decades in the sun. But I haven't found landscape fabric that will.

Get goats?
After continuing researching the absolute best fabric is rated for 9 months and still retain 80% strength. I found a company with surplus 81 inch tempered glass, wondering about painting a reflective paint on the back side and using that?
 
We call that a "yard" in Arizona.

Everything in Arizona is smaller?

Out here, a yard probably weights about a ton. We call 30 lbs a bag.

Oh, I missed the drop-down selection of 1600 lb stack, which they'll forklift into your pickup.


But I'm not in the habit of paying $1200 for one pickup load of rock.

Not sure if these guys have suitable reflective gravel:

No, weed resistant fabric covered by gravel is the most common form of "yard" in Arizona.
Desert areas, anyway. Farther north in the mountains you get grass yards.

So I guess they don't have the water bill I do.
One 2-month period I paid $910.37
(another as low as $151.32)
About 0.8 acres, with drip lines to trees and flowers.
On a Pareto chart, that expense is somewhere below several others, so not the most immediate concern.
 
Unfortunately I have to report my fist bad experience since starting the solar. I would avoid this company at all costs as
they will not attempt to work with you on any issues.

 
My drill press lasted a longtime but decided to quit. Everything is getting harder to come by and I really wanted a direct drive. It took a total of 6 open orders and 3 months to get one. Thankfully I called into my wires work and got her on double shifts for the next 2 months. The machine surfaces where so well oiled I made a small profit at the refinery.

If anyone is interested in further review etc let me know.

Decided to ditch my growatts and lithium batteries for the new 4million AH second hand dilithium matrix batteries from the enterprise.
2 12v in series for the driveway gates I have been working on. We are very far back off the road and the construction companies keep backing 18 wheelers into our driveway. They go off the side and just crush the asphalt down into the ground break large pieces off. Entrance was 34 feet so the gates are rather large. Found a 24 volt system that uses dual 30w panels so hopefully powerful enough.

Almost ran them over, not only do the birds love the panels :( but so do the rabbits. Needed to mow as the grass under the panels as it was very high. Just noticed the fur in time and stopped the mower. I find the older rabbits hanging out under the panels since I installed them. They are all very calm with me working on them and walking around and provide hours of great conversation.

They have conversations with you?
 
Sort of behind on the solar due to trying to research and understand all the connections. I decided to add a second inverter to help with the work shop that I have been working on but had not accounted for. I drew in paint a simple sketch of the ideas, but unsure of the charging profiles between the inverter and charge controller. How well will two 4p16s would charge together? I have been tempted to install one 4p16s on the left circuit breaker for testing but worry about the charge deltas for putting two together. I thought I could have one charged disconnect and charge up the second one if then connect both. I was thinking of adding some inline fuses but until I actually have them connected to see what would be a good fit.

1. Can I put two 4p16s together? Would I run into charging issues, they batrium will be monitoring all cells and both packs but unsure?
2. With the inverter and charge controller the manuals do not help at all about who should do what first based on charging?

I need to add a second ABB so one side can stay up in the event of an issue.

Gave up on my original battery supplier, I started asking for shipping and estimates back on 2021-01-27. They did a wonderful job on packaging and delivery but every couple of weeks I have checked back in to only get OK and no updates. I have ordered from two suppliers today and will update on how well they ship and perform.

Just about every company that cleaned panels was using some type of water deionizer: this one has a good price and had smaller outputs for the extendable solar panel brush I purchased. Like to find a cheap tds to see the differences.

This one seems pretty cheap:

They have a lot of cheap TDS meters on that site.
 
All breakers have been moved in both of the breaker boxes and ch-1 interlocks are installed, going to start on the busbars and batteries.

Worked on busbars and wiring/fitting all the connections.
