      Are you going to hook up motors to that mounting system to adjust the panels during the day to maximize exposure?

      @@b3owu1f Thanks! That’s a cool idea but it may be more complex than my original DIY intentions. I set out to design an adjustable tilt rack that I could adjust four times per year to maximize my solar angle. I’m at 31 degrees latitude so my optimal angle ranges from about 12 degrees in summer to about 48 degrees in winter. Today 12/21 is the shortest day of the year so I should be at 48 degrees tilt. I’m thinking bout adding 2 small manual winches to use on each side to more easily raise and lower the panel sections. They’re heavy at around 400lbs each side. If the system was to adjust through the day and track the sun, it would need a motor and light sensor. A tracker gives better performance but requires power and the performance difference can be offset by adding an extra panel to a tilt rack. If you’re short on ground mount space, a tracker is a good option. I’ve got a single pole DIY mount underway and I’ll shoot a video of that process soon. Lots of options with solar panel mounting and they’re all use case specific to each location and your design limitations. ☀️⚡️👍🔋💡🤠

      @@terrahillfarm Very cool. I brought that up mainly cause I saw another video where someone did that, and you can buy some rotation mounts for about $600 that hold 4 to 6 panels. and the claim is about 40% more energy output from each panel because it maximizes the sun all day rather than stuck at one angle. In your area with all the tress it may not help though as you said. But with the land you got, and all those panels it may not matter anyway. I am curious are you using per panel inverters or tying them all to a single point? I saw this video (ua-cam.com/video/Y2qs9VskGS4/v-deo.html) where he talks about the pros/cons of both approaches, but it seems like those inverters he shares are really good and will avoid one panel starting to hit shade from bringing down an entire block of panels from producing. Just thought I'd share in case you haven't seen it.

      @@b3owu1f Thanks! I’ve got another 18 panels to get up first but after that I might start playing around with automation for the PV. I love trying new ideas. Right now I’m using an EG4 6000ex AIO inverter. It’s split phase so it’ll run the whole house if the loads are managed. My next move will likely be to a hybrid like the Sol Ark, EG4 18k or the Schneider XW 6.5, which I really like. Like everyone else, I could use more batteries and solar panels! 😆🤣.

They have a better inverter than the EG4 for $1300. programmable, etc. But it has no solar inputs, which I am OK with as you just add MPTT controllers to the mix and I don't have any solar yet. But I'll likely stick to the EG4 for now, then move to the Victron later once I have a better idea of how I can set up panels and run cables, etc.

    Great video. I like your approach and have subscribed for a while now. I am planning an initial solar system for our North Texas property. I will start with emergency backup coverage and add from there. I want to be able to use my electronics and ham radios when the grid is down. I could have used that system in the past when the grid went down here in Texas. All the best from north Texas!

If you start with something like this, you can incorporate the battery and other components into a larger home solar system as you grow. It’s cheaper than one of those all in one solar generators but provides 3-4x more battery power. This ultimately puts almost every dollar spent into your eventual whole home solar system.

    I got my 11,040 pvw solar kit in August, I did not check the panels until two months later. One was smashed, the dealer did give me a credit so kudos to them. My EG4 inverters will handle 9 more panels. I am thinking of putting them on an adjustable mount. My first 24 are on a ground mount in 2 rows. I have them angled at 20 degrees (Florida). They are at peak production now, I got 11,450 watts during full sun two days ago. However in cloudy weather I get less then 1000 watts. I also need two more batteries so I plan on getting them and the panels at the same time.

      Thanks! Unfortunately panel damage in shipping is way too common! Ground mounting can also get expensive and rarely can you get panels ground mounted for much less than $100/panel. Like me, you are probably seeing your solar energy harvest growing daily, due to us moving towards summer! 👍 I think installing and tweaking your system in winter is a good idea since if you can operate off the solar in winter, summer will be a piece of cake! 🎂 We ALL need more batteries 🔋 🤣

      @@tekker8308 Thanks for the questions, the 6x6s were 12 feet long. I tried to get them in 5 feet but some spots were probably closer to 4 feet. All my ground is hilly so it’s never exact! I like the 6x6s and I just completed a 12 panel Brightmount set up using (12) four foot long, 6x6s. You can see it in my latest video. We’ll have a build video out soon on that project. Both the tall mount and the new mount ended up costing me around the same money. Probably $1,200-$1,400 in today’s dollars. Building a DIY ground mount that will stand up to high winds is tough to do for less than $100 per panel. I think I can reduce the cost some by using steel pipe, so I recently bought a welder and plan to do a large pipe rack mount with aluminum bolt on rails. We’ll see how much that ends up costing! 👍👍👍👍

    What are the size of your panels? Mine are 89.69" x 44.65" x 1.38". Seems like they may be similar as I also would need to extend the 10ft uni strut about a foot. Also wondering how long are those 6X6 posts? After having built this, do you feel that it was necessary to sink the posts the full 5 feet? I don't have an auger that can go that deep. Maybe adding a 4th post for extra support then three feet would be sufficient.

      @@chrtravels Thanks, the panels I like to use are generally 108 cell panels around 400 watts and they are generally close to 65”x45” in size. I find these are as big as I want to work with on a ladder or roof. The 6x6 posts were 12’ long and I probably got them closer to 4-4.5 feet deep. Shallower would work but I’d add more concrete. An extra post wouldn’t hurt and if I had to do it again, I’d have purchased 20ft sections of uni strut to avoid splices, they will sag a little at the splice. The 2x6s I used to anchor the adjustment arms have bowed so a shorter span or 2x8 would work better.
      I just built a second 12 panel array using three EG4 Brightmount racks with extensions (for 45”w panels) and I mounted these on the tops of 6x6 posts 4’ long buried into the ground. The total materials costs were actually about the same for both arrays but I prefer the Brightmount racks lower to the ground. They don’t have the range of adjustment that the taller rack has, but they are easier to build and maintain. I’m editing a video showing how I built the second rack and should have it out in a couple weeks. Overall, the 6x6 posts are pretty stable and make a solid mount however you design it.
      Im also going to be installing some panels on a metal garage roof and will probably use uni strut for that application. I found some nice mounts on Amazon and will try those out with the uni strut. Again, it would be wiser to get the 20ft uni strut but it’s tough to find around here.

    If you lived in a rural area where you have good electric service and all the lines are buried, so outages are almost non-existent, would you still be motivated to install solar? Rates are $.12/Kwh, if that matters.

    • @terrahillfarm
      @terrahillfarm  10 місяців тому +1

      Thanks! With dependable power ⚡️ and no serious hurricane/tornado/wildfire threats, I think you’d be fine with a manual transfer switch and back up generator. Ideal size would be 3-4500 watts and inverter style is preferable if you have newer digital appliances (refrigerator, washer, big screen TV, etc). Dual fuel (gas/propane) is also more convenient. This can easily be done for $900-$1300 and would insure you have emergency power if you lose grid power. There are all in one solar generators in that price range, but I’d always start off with a generator. It’s like insurance, you may never use it, but you’ll regret not having it if you do need it! 👍☀️🔋💡💰. Solar is a bigger investment and it takes some time to pay for itself plus a learning curve. It boils down to how much do you trust your electric provider to be there in an extended emergency? For us, it was worth it!

I’m still experimenting and trying to find the best way to use these bifacial panels but one place I really find they excel is early AM and late PM. Capturing low level light from both sides enhances the performance and gets me a little more total power each day. I think putting down white rock under the panels might also help.
