Wow.. I’d pay $25 all day for those. I’ve got at least 2-3 charge controllers that I could use them with, one starts working at 120v and goes up to I think 250v, and another one goes up to at least 300v.
-
Rereading. is each panel that high of voltage, or are they that high when connected series?
If the latter, why not just connect 1/2 series, 1/2 series, and those two in parallel, dropping the voltage within a safe range, and take that directly to the charge controller? Or maybe a 2nd, charge controller, one for each string, leaving everything else the same?
-
What is the brand and model of those panels? I’ve not seen any over maybe 60is volts. Need to broaden my information base!

I think a lot of the “noise” boils down to what the person is accustomed to or takes to be “normal”, it’s amazing how one would turn all Karen at a single rooster when 20 dogs are barking at all hours around the neighborhood.
Their preconceptions color their perceptions.
Where wind is appropriate, and viable (cost, maintenance), etc and the turbine is of appropriate scale, and constructed of materials which on the whole are at least as, if not more recyclable than any other form of energy generation, There should be no logical argument, but alas.. one thing more rare than gold or precious gems, is logical thinking.

Perfect!

Questions:
what is the dc voltage of your system? 12/24/36/48What is the rating for your inverter, and what is the largest load you need to run, evern for a few minutes?
The reason I ask is, one if the significant differences between lithium and lead based, is the lithium has a bms, even if diy. Those bms’s are rated at 100 or 200amps generally.
1300W on a 12volt system (I used 13 vdc for the calculation) is 100 amps. Meaning, if you ever, much less routinely have total loads over 1300W, you need either a 200amp bms, or two batteries with 100amp bms’s
on a 24vdc system, then 100 amps (using 25vdc for calculation) is about 2500W
Just something to think about. Lead is made to surge hundreds of amps for a few seconds, Depending on the bms and cells, a lithium may go 50% over rated capacity, so a 100amp might go 150amps for a few seconds, then shut down.
It’s not just about the size of the cells, sometimes one needs multiple “batteries” for the amp load.

The main problem with the vertical is the sideways loads on the single bearing on the bottom. The taller the vertical blades, the longer the lever, the more the side load.
The higher the wind speed, the stronger the force, on the lever, then on the bearing while trying to spin. They just wear out faster.
Horizontal turbines, spin, but don’t have much if any side load on the bearing(s). There were a couple of other physics-based problems which have yet to be “solved” thus far, and that I’m not smart or educated enough to remember or understand. I’m all for progress and innovation, heck, love it, but that doesn’t mean everything new or neat, actually works.
That said, at some point, I may get a (horizontal) turbine anyway, but I will do so, fully knowing, it’s an experiment, which if it provides noticeable, or significant output, that is a bonus, but it will go up with little if any expectation, and not factoring it in as a part of a critical supply system.

There is a skete in Grand Junction, TN a bit west of Memphis that I visited a few times. Mother Nektaria (now passed), was probably the one person who was the most accepting of me, under any and all situations. When I finished Nursing school, in my 40’s (RN), I was so stressed, I just called her to make sure the guest house was not in use, and just went to chill. If I wanted to sleep, that was fine, if I wanted to read that was fine, if I wanted to join her in any of the hours or other services in her small chapel, she appeared pleased to have someone help read. Haven’t been back to that church or skete in years now (had to move to care for my parents), but probably miss her more than the actual church. I can’t go to any other (non-Orthodox) service or church for any reason, and feel like it’s actually “church”. Likely judgemental etc, but just how I feel. The quiet, the smell.. Never a doubt it’s a church, rather than someplace a “show” is put on. The only one where I am now, is a very small chapel, that I don’t think has a permanent priest, and is an old calendar, Russian offshoot that I don’t believe is in communion with the rest of the church.

Live streaming “The Rudder” or another source?

Actually in Arkansas

I was Christmated “Onesimus” at St. John’s Antiochian in Memphis.

the latest information I have gathered is from taking this course via Verge Permaculture. Dan is a Phd, who has been studying, writing about, designing, and living life for like 40 years, in multiple environments, In this short clip, he makes it sound magically perfect, but I assure you, in the full class he was quite careful to encourage one to evaluate the site before considering wind (and he is a certified wind something or another, I forget the exact certification, but does official evaluation of a site to see if wind is appropriate, and cost-effective). He has very specific reasons why, as yet, vertical turbines aren’t “ready for prime time”. I’m not making this stuff up, or pulling out of an orifice, just passing on what I’ve learned either personally, or from actual experts.

Nope, I don’t sell anything. I’ve talked with a couple, and heard presentations from several who have tried them and say they just didn’t live up to the promise, and admitted they really just wanted to be the case where it worked, but didn’t. As for vertical turbines, one problem area is that the bearing is at the bottom, and when the wind is there, it pushes in a way that puts stress on it wearing it out faster. I’m for what works. Not just what is neat, or cool, or I feel should work.

I’m curious, have you found any reputable research or long-term, non-sales pitch reviews indicating verticals are anything more than hype? I haven’t.
Regarding horizontals (the industry standard, for a reason), other than in very specific situations, and where the turbine can be mounted quite high, like 100 feet or more above the trees, houses or other structures in the immediate area, while they do generate power, rarely do they generate enough to warrant the cost, especially if the same money, for purchase, install, annually bringing it down to inspect and/or repair and re-erect, was instead put into solar, or batteries, pencil out. Again, I love the concept, but over 15 years of at least casually watching the space, I’ve seen very little evidence that it is worth it.. again other than in very specific locations.
We all believe our situation is different, and it is, but that doesn’t mean it’s the proper setting for the cool thing. (most of us also believe we are above-average drivers, which isn’t possible)

I’ve not seen any research or reviews that indicate vertical turbines are anything more than a marketing gimmick. I’ve not even seen any reputable wind/solar companies selling them (though of course, I’m not aware of every single company). For instance Missouri Wind and Solar… horizontal’s only.
