Ethanol is subsidized.
Interesting indeed, although PV does not have the flexibility of ethanol so as a practical matter the comparison is flawed. US farmers are also heavily subsidized to produce corn for ethanol (typical republican hypocrisy.) If farmer profits decline from the switch to PV production they will fight the change.
Correct me if I am wrong, but ethanol farming is only profitable because of the federal mandate that a certain percent of all interstate gasoline sales must include ethanol, no? So, without the mandate no one would chose to buy ethanol correct?If only I had a dollar for every dumb policy in the USA. Ethanol farming is profitable. Solve that with your alternative.

Ethanol has slightly higher octane than gas so can be used to raise octane of cheap gas. However, it has 33% less energy than gas.Ethanol is a lead replacement. I actually do not know if it in turn can be substituted. But ethanol production is subsidized so my guess to your question is no ... it gets used because it is "cheap."

I thought you used power racks ?Reinventing utility scale solar from the ground up – literally!
Erthos forgoes tracking mounts and installs utility-scale solar directly on the dirt.pv-magazine-usa.com
I'm done with mounting systems. My latest arrays are literal ground mount. Just lay the panels on the ground. Shovel snow if necessary (or not - winter production is low anyway) but much cheaper.
Also tired of dealing with regulatory agencies which just delay and contribute nothing
Yes, I'm trying a set of PowerRacks for an array. They are a minimalist racking system that looked attractive. I haven't installed them yet and the panels for them are currently flat on the ground (producing) until I can get the ground cleared for the PowerRacks. Should have better production and snow shedding since they are held at an angle but still close to the ground.I thought you used power racks ?

I do have another array that is flat on the ground and I have been happy with that.
We'll see.
Panels are cheap and I don't want to spend a lot on mounts.
Thanks for this information. My site is a slope with lots of brush to be cleared. I'm using two buckets for each oversize panel. Hopefully it won't be too much hassle to get them lined up.I'm in the middle of installing mine. My ground prep is on a hill and is more work but I think that part will be finished by Monday. Then it gets easy. I decided to use 3 powerRacks for every 2 panels. It works out to ~ $160 for 800 watts = 20¢ a watt pre tax credit. I think it is an easy choice if they work for your case.
I like the system, but be forewarned: the racks that carry combined panels have to be flush with each other, and flat is highly recommended. Small deviations cause headaches with the locking bracket.
Hopefully it won't be too much hassle to get them lined up.
Two buckets per panel is the easiest, but you will still want to work with a level. IIRC the buckets have to be within 0.5" of each other
Thanks for this. As I clear brush, I'll be able to level the ground. I was planning to dig them into the ground a bit rather than just sitting on the surface.I may not have been clear. The buckets have to be aligned, but I was saying that they also have to be at the same height. They can be tilted a little, but then each bucket attached to another has to have the same tilt. I decided to dig little bays for each bucket so that they could lay level, and then I only have to make each bay at the same height as its attached neighbor. I made a simple level accessory out of wood to aid. I'll post a picture of it later

How much weight (and what kind of fill) did you put in yours?
Looks good. It will be a few weeks before I can start on this project. I've got a few other pressing things to finish on my house first.First I add back the dirt I dug out for the bay, then I add rocks and some concrete scraps I have laying around. I shoot for a level fill about 3/4 to the front (lower) top. I also plan to put a piece a piece of wood in front of the bucket and then drive into the ground some rebar in front of the wood. No slippage is my motto. As an aside, like any project of PV rows, leave enough space between them to avoid one row shading another. Give a holler if you want a hand with the trig.

It's kind of a form of regulatory capture. The benefactors of the current paradigm do not want to upset the equilibrium, (or at least they want to “muddle through” it on their own terms). Which is difficult since there are competing interests. So in regard to public interest without some mechanism to facilitate change this will be slow undeliberate process as the “powers that be” attempt manage the disruption, (manage the disruption being a bit of an oxymoron). Think of a Nash Equilibrium where all the participants do not include all the participants or include the environment.Reinventing utility scale solar from the ground up – literally!
