Thank you for putting this together Rodney! I'm presently building my tilt array based on this setup for my large 530W panel 14 panel array in South Carolina! Upgraded to longer/larger bolts and the 6x6 posts. Appreciate you putting all of this together! With the current cost of wood (and larger wood due to my sized panels), larger hardware and such it's ~$1500, but it's still quite a bit cheaper than a commercial array. I got a quote, the cost of the system (minus concrete) was $2800, BUT they wanted $2500 shipping?!? Nope!
Hey Rodney... wanted to express my appreciation for your videos 👏👏🙏🙏 . I'm just starting my journey into solar and finding it all a bit intimidating. But, as I continue to watch your videos, I get more confident each day. I'll likely start making purchases within the next 30 days and hope it doesn't become obsolete before I can build it.
Great job! When you get longer bolts, if you get them long enough to add one more nut, you can torque the two nuts against each other, so they won’t come off, while leaving enough play along the bolt that the array can be tilted more easily.
McMaster is expensive sometimes. We order from there at work, 99.9% the order is correct, and 95% it shows up next day. They are absolutely the best supplier on the planet. I am an engineer, and grade 8 is massively over kill for this application, which is the majority of the cost. Grade five would be more than adequate and close to half the cost. I’d recommend using a jam nut or a nylock nut. The torque required to keep the fastener from coming loose isn’t even possible without destroying the wood. With nylock, if it becomes loose, the possibility of the nut falling off the bolt is greatly diminished. If nothing else, periodically check that the lock washer is still compressed.
Dude ..... I watched a video a while back and thought to myself .... 'thats the best wooden solar rack I've seen yet'. Well .... The solar rack you built is now the best one I've seen yet by far since it can tilt and isn't overcomplicated. Ha ... If you can patent this thing ... Do it! I bought a pallet of 14 - 255W Canadian Solar panels from San Tan I'm itching to get up and running. I think I ended up paying $45 each for them with tax and freight included. I'm optimistic I can pull 14KW a day from them on average. Thanks so much for sharing your awesome money saving solar rack project!!
Pretty ingenious tilt array. I am working on a 4 panel array behind the house but at ground level as we have an almost perfect Southern exposure with no shading. Getting into solar and your videos are excellent as you started small as well and expanded. Merry Christmas to you and your family.
Congratulations for a job well done. Thanks for sharing!! To reinforce those 4x6 posts - - - > think about getting 1/4" steel plate cut to the width of the 4" side of the post. Use lag bolts to attach. Again, thanks for sharing. Have a blessed day.
Hey thats a good idea. It has been working well through wind and storms so probably fine fir the most part. I would still use 6x6 post next time to make me feel a little better and that is what I tell anyone looking to build similar
Awesome video thanks happy holidays, I designed my own adjustable arrays that can be positioned at 25 and 45 degrees (september 20 goes to 45°, march 20 goes to 25°) much more efficient compared to the fixed 35° array
Absolutely brilliant for flat land. Unfortunately My property slopes too much so I had to make 4 frames and stairs step them and mount them to to cinder blocks because my soil has too much rock.
In the Midwest, Menards also has the Grade 8 hardware relatively inexpensive. I got my strut channel nuts from Amazon in a 100 pack relatively cheaply.
Love the tilt array. Nice break down Rodney. Maybe you can automate it to one-direction daily track sometime in the future. Those panels are at a great price right now. Under $0.40 / watt is good and this is at $0.26. I'd love to see how Bifacials would do on this raised array though, that would be awesome.
Hey Rodney, love ya for what you do to help those of us not as comfortable as you with solar installs. Your videos have helped me a lot. Just made my first purchase from Signature Solar of the EG4 6000xp with the conduit box and the EG4 Indoor Powerpro Battery along with 10 of the Boviet 450 watt Bifacial Panels. And I used your discount code, so thanks for that too. I was wondering if you could perhaps do a brief video on how you have your solar panels grounded on this tilt array. Or perhaps just an explanation. Again thanks for all your teaching.
I quickly looked through the comments, but didn't see anything regarding grounding the panels. Did you add a ground rod, etc? Thanks for some great videos!!
@@rodneyhunt Thank you for making your video I used this as sort of a brainstorm to make my own panel mount. I mounted a single row of 10 blade bifacials 395 watt panels. I have been looking into linear actuators paired with single axis control units with anemometers on them to tilt flat during windy weather. I didn't build mine as sturdy as yours. I used 2x4's and 4x4 posts, but I only went 1 high with my panels.
I don't see where you have the square flat pieces that are holding your panels down are on your list. What are those? I have the rest in my HD cart. I did get your box of zinc washers but those are round.
Can you explain your lumber list? What is the Width and Hight (bottom to top)? You have • (3) 2x6x12 pressure treated • (8) 2x6x12 pressure treated • (3) 2x4x8 pressure treated But I cannot see where you used all of those. Love what you made! Thx for sharing.
Rodney, going to build something just like this and was wondering about putting a 12 volt linear actuator to move it to adjust. How far does it move from summer to winter settings?
I have been looking at some from vevor as well. Would need to get an exact measurement but several feet for my area. More than the sizes I have looked at so far
Not that you need another array.... How would the same set up, but with (a)the posts on a N/S configuration with heights of posts equal to a 30 deg angle (b) same set of panels (c) 1 axis (E/W) solar tracker with Heavy Duty 18" linear actuator, small 12v bat, wind speed indicator (to make array go horizontal at a predetermined wind speed) So that you pick up sunrise light (morning is usually when off grid bats are lowest SOC) and sunset light. Wonder how this would do? Not as complicated/expensive as 2 axis, but tracks E/W movement of sun automatically.
@@rodneyhuntgrin i was at store going through parts and i was like ok hold up i missing sumting lol good thing i had access to your videos i got 3/8 x 4” lag bolt i also thought you bolted solar panel from the frame the holes and i was looking at the 2 1/2 and thinking this is too long, after frwmi utes went back to video warched where you put the superstrut on wood then we saw the square unistrut washers so went back to aisle with unistrut and looked for the square pieces, bingo. I was like yee haw now we in biz. 😂🙌🏼
@@rodneyhunt i'm at 35.6Lat so i'll be going from 35deg winter to 75deg summer tilt... you've really swung me around to wood versus steel, i was gonna hire a welder and set drill pipe in concrete and do drill pipe cross rail and way way more money and i've got no real wind issues... thanks a million KWH Mr. Hunt !!
I started ordering parts today for ground mount tilt. I am using 4 (6x6) 3 foot into ground 10 foot apart. How many bags of concrete did you use for each post? I am going to mount 18 370 watt panels each weigh in at 50 lbs.
@@rodneyhunt Perfect 4 it is per post. I decided to post every 7 foot for a total of 5. I need Beefy as I am in Florida. Thank you for the hardware tips I got some high strength 7/8 bolts from Mcmaster.
Those are some impressive numbers. Based on them, have you calculated out your ROI..? GREAT price on a 320w panel. I have 2 arrays here.. 1160 (4x290's) and 1200 (6x200's bifacial on a dual axis tracker. video on my channel. 400Ah lithium. I am powering this pc on solar power now. I'm loving it.
No I have not calculated roi since self reliance and peace of mind was my only goal. I could do it at some point just to see though. Yes I love my solar as well!
@@rodneyhunt i just got a aproval for building a rack last month i had to wait 4 weeks because i live within 20 km from a nature reserve i had to wait and make sure a fishing club 16km away did not fear for the frogs and lizards in their area for example about 20 different clubs and authorities had a chance to complain about my plan thanks to the nature reserve (EU natura 2000 ) the people i live next to have nothing to say 😂
insted of using 6x6 i would add around 45 degree angle support beams sitting right under where the panels are fixed to the 4x4 and fix the support beams to the ground that will add more strength then adding more thickness and it should be cheaper in both wood and bolts those support beams will stand presure better from the angle the wind it blowing, then a vertical 6x6 even a tree can fall in a storm, because it is not supported the right places you are also fighting the strength of the ground not just a matter of 6x6 or 4x4 better to be pushing on the ground then pulling the biggest strength you will find in a big metal tube at the scrabyard after all we dont build skyscrapers out of wooden structure for the same reason i got my self some tubes from old street lamp poles for example from a friend that collects metal i would also argue that with bifacial panels the adjustment should probetly happen in a rotation like it was a clock on the ground ofcourse with some sort of solar tracker you have less shading if the panels are right in the middle of the sun all the time vertical bifacial panels produce more thanks to cooling and less shade on the backside.. compared to a normal racks no matter if you adjust for the angle of the sun
Good ideas! Just didn’t want to take up more ground room. Has been fine in 60mph winds so far. Should be great for most situations with a 6x6 since the 4x6 is working good. With enough force anything can break but just want to mitigate as much as possible with a smaller ground footprint.
Great informative video and pretty much what I’m going to do for my array. Just bought 13 370 watt panels and one 6000xp. Wonder if greasing the bolt shaft would make it even easier to tilt? Maybe even a sleeve insert of some type with grease?
All your fasteners into the pressure treated. I am wondering why nit use stainless steel. The chemicals in the wood are very corrosive to steel fasteners. Especially the main bolts which the unit pivots.
Great point! Didn’t find straight stainless steel bolts at the time. Could probably use a lower grade bolt so I can change out to stainless steel one day. These are zinc yellow chromate plated I believe
i was comment about the Renogy that were 400 watt the price was $550 a panel these are $540 for 5 panel. i was thinking you might have an ideal why some are so much cheaper, is it because there "cheaper"? Hey thanks for the answer! @@rodneyhunt

Hey glad to hear that! Helping more people to get on solar to be more self reliant is one of my goals.
Great Job Rodney. When I make my next ground mount I'll definitely use your example. Happy Holidays.
Thanks. You too
Thank you for posting the bolt info, that was very helpful.
Glad it was helpful!

Sounds like a good plan for your terrain! 👍
Wow 5 secs and just loving the setup already. Awesome.
Appreciate that! Like your name. LIVE FREE!
If you want to make adjustments to the angles add a winch so you can easily make adjustments.
It is easily moved by hand but a good idea. 👍
In the Midwest, Menards also has the Grade 8 hardware relatively inexpensive. I got my strut channel nuts from Amazon in a 100 pack relatively cheaply.

Hell yeah🤘🏻so cool to see Morpheus doing well in the Solar world these days! :D

That's awesome, not bad price at all. Will definitely be doing this kind of set up when I get the money. Thanks again for a great video.... Jeff

The grounding video is on my list to do. Thanks for your support!
Use 3/4” gray pvc spacers around perimeter, cut slightly less than panel frame thickness. Keeps support under that big square flat washer.
Good idea 👍
You put out some very good content so Merry Christmas and I am now subscribed. Keep up the good work 👍🏻
Thanks, you too!
Great videos! Could you do a total cost of your entire system, and when you expect it to pay for itself?
Will do 👍
I quickly looked through the comments, but didn't see anything regarding grounding the panels. Did you add a ground rod, etc? Thanks for some great videos!!
Yes it definitely should be grounded. Still have that on my list to show on a video. Each ground mount has a ground rod
Have you thought about using a solar tracker system with this design?
I didn’t. I do not know what equipment would be needed with this design. May do some research when I get a chance. Thanks

Thanks again Rodney l found your parts list .
👍
Did miss the video where you mounted your panels to this rack?
I think the install video should show it
Tractor supply you can buy bolts and things by the pound
👍. I looked at agrisupply who does the same but just wanted grade 8 bolts. Probably overkill but since I was not sure I went with the best.
I don't see where you have the square flat pieces that are holding your panels down are on your list. What are those? I have the rest in my HD cart. I did get your box of zinc washers but those are round.
I thought I added the unistrut washers. You should be able to find 1/4 unistrut washers
In the description it says unistrut 1/4 nuts, washers(will add unistrut to make it clear), and bolts
Can you explain your lumber list? What is the Width and Hight (bottom to top)? You have
• (3) 2x6x12 pressure treated
• (8) 2x6x12 pressure treated
• (3) 2x4x8 pressure treated
But I cannot see where you used all of those. Love what you made! Thx for sharing.
Looks like you have (12) 2x6x10 pressure treated (plus a bit more to connect the middle)
Will try to do an update video
thank you for the great video and the specs and info , that's very helpful
Glad it was helpful!
Add your lag bolts and washers for securing the unistrut to the parts list. Thanks
👍
could one 2 x 6 be used instead of two attached to the 4 x 6 post or did you figure panels would be too much weight?
Two makes it more rigid and gives additional attachment points for unistrut
Are the posts aligned in the East-West direction?
Yes. 👍
You're the man, this is exactly what I'm going to do
Been working good! 👍
Thanks for the breakdown. You inspired me to go copy you 😁
Nice 👍

Hey question the bolts you used to mount unistrut to wood is that in parts list? The bolts in list i think r for the solar panel to unistrut?
No forgot that. They are bolts but not sure of size off hand. Drilled a pilot hole first before installing. Will look for size

insted of using 6x6 i would add around 45 degree angle support beams sitting right under where the panels are fixed to the 4x4
and fix the support beams to the ground
that will add more strength then adding more thickness and it should be cheaper in both wood and bolts
those support beams will stand presure better from the angle the wind it blowing, then a vertical 6x6
even a tree can fall in a storm, because it is not supported the right places
you are also fighting the strength of the ground not just a matter of 6x6 or 4x4
better to be pushing on the ground then pulling
the biggest strength you will find in a big metal tube at the scrabyard
after all we dont build skyscrapers out of wooden structure for the same reason
i got my self some tubes from old street lamp poles for example from a friend that collects metal
i would also argue that with bifacial panels the adjustment should probetly happen in a rotation like it was a clock on the ground
ofcourse with some sort of solar tracker
you have less shading if the panels are right in the middle of the sun all the time
vertical bifacial panels produce more thanks to cooling and less shade on the backside..
compared to a normal racks no matter if you adjust for the angle of the sun
