DIY Tilting Solar Mount Build! 

Step-by-Step Build Instructions for DIY Tilting Solar Mount: Prepare the Poles: Use 4x6 poles buried 3-4 feet in the ground. Ensure they are all straight and level to the top of each other. Use high-strength concrete to stabilize them. Install Bolts: Once the poles are in place, measure down two inches from the top of the post and put a center mark on that two-inch line. Drill a 1-inch hole, and insert an 8-inch-long 7/8 bolt. Repeat for each pole. Build the Frame: Cut treated 2x6 boards into 9-foot lengths. Use a saw to reverse crown the boards, so the high side is down in the center. Put two washers on the bolt, then slide the board onto the bolts. Add another washer to keep the board from locking to the wood. Repeat the process for the next board. Use blocks cut from 12-foot pieces to lock the boards together. Put two screws on each side and screw them together. Build the Rest of the Frame: Divide the nine-foot boards into three-foot sections, and measure and cut pieces for the inside blocks. Screw these in place to support the 2x6 boards. Mount the Solar Panels: Install hangers to hold the solar panels. Measure the outside edge to the center of the next block to ensure they are all the same length. Screw on the faceboard, then attach the cap board. Test the Mount: The completed mount can hold up to 12 large solar panels and cost around $360 to build. The mount can be easily tilted up and down, and it can be moved around to adjust for seasonal changes. Note: It is recommended to use ground contact pressure-treated lumber for this project. Also, make sure to adjust the mount monthly to ensure maximum power output.

Best vid on the tube for tilting solar panels

Just finished my solar project and want to give a shout out for a great plan and thanks for your kind assistance! Several people including inspectors, utility workers, material suppliers, and trades people have openly admired the ground stand and wanted to know where I got the plan. Of course, I told them I got it from you. Here are few notes and comments. 1. I live on a wind-swept plain in the upper Midwest where the winters are long and cold and soil is sandy, so I used 12" x 48" Ceme-Tube Plastic Standard Concrete Forming Tubes to get below the frost line, minimize frost lock, and provide sufficient ballast. For additional stability, I also added a second row of posts four feet behind the main row (Picture 1). That, combined with 1 ½” vertical gaps and 1” horizontal gaps between the panels meets national code requirements that structures can withstand sustained winds of 106 mph (which, where I live, is expected once every 3,000 years). 😊Since installing, we have had wind gusts in the 40 to 50 mph range, but you would never know it from the panels as they haven't shown even the slightest movement under those conditions. 2. My panels are each 405 kW and measure 40” x 72” mounted horizontally three high in four vertical columns. At that size, I was pushing the span limits of the wood framing and getting slight sag on the outside edges, so I slightly modified the original plan and mounted the four outside fascia boards on the inside with hangers lined up flush with the front of the struts. Then, I went back and added reinforcing boards on the outside (Pictures 2 and 3). 3. Finally, for additional structural integrity, I added 2x6 boards at each corner mounted perpendicularly at 45-degree angles (Pictures 4 and 5). 4. For adjusting the angle, I used 14 Gauge Slotted Steel Angles mounted on each of the posts (Picture 6). They are more than strong enough for the job because the array is nicely balanced and the wind exerts equal pressure on the top and bottom of the array. And, most importantly, the angle irons provide additional support to eliminate any sag or fatigue that might eventually develop in the wood components of the structure.

I'm looking into a solar system, I never liked the fixed system. I'm in the tropics and my location is almost in a valley and I was thinking about how to utilizing the sun the entire day as it moves over, I'm glad I saw this idea. Thanks for the video

Saw ya on Facebook, All I can say is what a bunch of A-holes on there.

I really like your solar frame.

Good video James. Here in Alaska it's best to build mounts that can go just past vertical for the solar panels. That way we can catch all the very low sun angles for 6 months out of the year and going 5-10 degrees past vertical greatly reduces snow buildup on the panels, and it also catches all the reflected light from the pristine white snow which can be slightly higher output than pointing the panels directly at the sun. I think the next big thing on solar mounts will be ingenious ideas to help better harvest the full potential of the newer double-sided panels which are able to collect more reflected light than just the front single surface.

Excellent mount. Probably one of the better designs that I have seen for DIY. Thanks for taking the time to make the videos.

Looked at a lot of these this is pretty impressive Thank You.

Excellent design and video! I have some serious wind in North East Ohio by the lake and will be using your design. I'll be adding some overkill. Concrete and posts at a 45 degree angle about 4' behind to help brace it. 40-60mph gusts. Not many trees around. Thanks for sharing!!!

Very nice mount. I'll be curious about the next video

Great video. Thanks for sharing!

tuba six!

Looks good. I just put my post right into the ground. No concrete!

Very detailed and instructive video, great help for me and others! Well done! 👏👏👏!

I would consider adding another block of material in-between your pairs of arms that is set to be a positive stop when the array is at it's most vertical orientation. My biggest worry with a system like that is it's TOO easy to move, especially when strong winds turn that entire structure into a giant sail.

Great video. Thank you for making it.

Very well done. Clear instructions. Thank you! Will be biilding mine this winter.

Use the trailer jack. That way you have a crank handle to tilt your panels

nice Step by step explanation

Love to add a linear actuator to this

I just ordered 14 panels and researching ground mounts DIY. Found you! I'm in Doyline, Louisiana. Already have a dual axis tracker with 12 panels, probably will put and actuator to tilt with anemometer to know when to go flat for high wind.

I would put some 10ga plates at the pivot to spread the load to the post. The uplift from wind loads has me worried about relying on 1” of material to keep it in place.

Nice work. I suggest you use bushings in your posts. There should be a way to set up automatic positioning by monitoring panel output and using a linear actuator.

Looks good. I need my power in the winter time for heat pump systems. So all mine are fixed tilt from 45 to 66°. I don’t make any adjustments because I have five to ten times the power coming in during the summertime. You need about triple the solar array for the winter time to make it through. Totally off grid. I produced 17 MWh in the last year.

You are good!

Nice job. You’ve given me a clue (since I had none) to how I should do my single panel mounted. Thank and I hope you’re better for more videos in the future.

With the 7/8 bolts did you use a split lock washer between the nut and last washer? Great video thanks!

If the rack was split into two halves, that would make tilting it manually even lighter.

What is the distance between the 4x6 posts? What is total length and width of array. Great array and video!

Did you continue this build in another video? Panel Mounting? ect?

Bonjour, Les poteaux enterrés, ce sont 14x14 - 16x16 .....ils font qu'elle longueur ? Ils sont bétonnés ? Beau travail 👍 Merci

Thanks, the DYI Tilting Mount was exactly what I was looking for. I will be installing a smaller system with 3 -480W panels each 6 feet tall. Would it be ok to use 2 posts for the 3 panels or do you recommended a 3rd post?

Did you devise a way to tie the tilt assembly to the posts to enable monthly adjustment?

Are the first 2x6 you put on did you center the hole on it, when you drilled it? or is it offset? thanks great video

Thank you, James! Question: just to make sure that I got all the dimensions correct, can you confirm what is the center- to-center measurement between the ground posts?

When you drilled the holes on the 2x6 did you centre it to the 9 ft board?

How did you know how long to make the topp and bottom?

but where do you buy the bolts?

How much did you cut off the 4x6?

Have you ever considered a manual jack screw ( manual linear actuator) type of setup for you're tilting mechanism? I'm planning on building a similar adjustable wood ground mount and that is what I plan on using on all the posts.... quick question so you're using 4 x 6 posts... what diameter were your holes in the ground?

What are your facial boards length.

what is the distance between posts in ground?

Material links?

@swan433 I think you misunderstand @Scat.original They are referring to the first 2 - 2x6's he put up, not the 4x6's
