    That’s a real big change in the angle. what happens if you have a wind storm?

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  21 день тому +3

      It is a big change. It really represents how different the angle of the sun is between summer and winter. We have zero concerns about the structure tipping over as it is fully cross braced and each post is in almost a yard of concrete. The array is through bolted at every connection point so I’m not concerned there either. I will have to watch side to side movement at the top of the panels, but the panels themselves will provide shear strength to prevent that. When we do get wind it is usually from the south. The panels are protected from a north wind by the trees behind it. I am more worried that a tree will fall on it😳

    Thanks for the video it’s always interesting to see what people come up with. I’ve been doing off grid solar since 1998. I live off grid myself and I know all about cleaning snow off panels. Mine are all ground mountain so I can reach them with my long handle broom. I also have a leaf blower that’s pretty powerful cordless electric. I did see something that is a bit alarming make sure that the solar panel prop rods don’t come out when you are under the pivot point because if it fell, you could be trapped and you wouldn’t wanna be squished by your beloved Solar Panels. Keep up the good work.

      We appreciate the advice, safety is always a priority. the push rod is captured by a pocket while lifting, I was concerned that the pocket might not hold and I will inspect it prior to each move the pressure from the winch cable holds it tight into the pocket

    That is one large set up. I did mine buy using water pipe and 4x6 posts like an H and then tilt the panels with a harbor freight boat winch that was $19 bucks. Been working since 2015 here in Michigan. nice video.

      i also use the same H shape, just with metal light poles at the end
      im amazed with how complicated thse setups often are
      specially if you buy a finish product
      a rack that cant tilt uses more materials , then the H shape
      they often have 6-8 poles in the ground
      makes no sense to do more work and use more materials in many situations...
      i have 3 poles in the ground for 2 racks

    I have 11.6kw this year, lowest day was 6.2kw vertical with snow average day 10.2 kw in overcast. I bet 7kw more solar and we could sell our generators. I never need to clean my panels, the snow boost was so high my 3300 went to 3800w before it over amped, had to shade a panel. Gen time Nov last year 150hrs, this year 14hrs. I don't know about your area but my weather app promises sun 5 days a week and haven't seen 1 min since Nov 6. As far as dirty power I run the 9kw gen at 6200w and get a steady 60.1 hrz, I turn off all surge appliances as that causes the low/high freq errors.

    Nice work, though it looks a bit complicated to change the angle, and I think in a storm you're likely to lose some panels. That's a lot of wind area to be secured with just two clamps. If it survives the storms you might consider running unistrut across your wooden rack so you can have four clamps per panel instead of just two. I can't see your pivots, though I'd be a bit worried about those too. Incidentally, the chargeverter actually outputs DC, not "clean" sine waves. I'm not familiar with your mppt/inverters but I've used a fairly funky generator with my EG418K PV all-in-one and it worked fine to charge the battery without a chargeverter. As cheap as the harbor freight winches are you might consider one for each set of panels pulling down the bottom of the panel set rather than pushing. I assume the unistrut poles are to lock the angle once it's where you want it. You could still do that. I designed my rack to be more or less balanced and I currently use winches on both sides, one to pull the rack down, which you can see in the first picture of this blog post, the second you can't see is on the other side to pull the pivoting rack up so I can lock it with cable tension. Next year I'll replace the cable stuff with a few linear actuators and an single axis seasonal "sunseeker" to manage the angle automatically.

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  17 днів тому

      Thank you for your advice I know it comes from experience. we really hope that our system can weather any storm. each panel is held on by 4 - 5/16x3" lag screws but I like the idea of adding more anchor points. We know we misspoke about the chargeverter we were just trying to say that it will accept dirty power where as our mpp inverter will not. because of our snow load I couldn't balance the arrays like you did because in the winter the bottom panels would be buried by the sliding snow or I would have to make it much taller. the sun seeker sounds like it will work awesome! Thanks for watching

  • @burrowsal
    @burrowsal 18 днів тому +1

    I'd offer the suggestion that you build hard stops at the winter angle so you have the angle every time and don't have to use the angle finder. it would also support the array. Do you have plans you could share? I really like the dual function of array and woodshed!

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  18 днів тому

      Good idea, now that we know the winter angle we’ve marked the super strut so we don’t have to use the angle finder each year. We don’t have plans for the solar structure/woodshed but if you watch our solar play list you’re welcome to copy our design, of course because you’re location is different than ours you may want to have an engineer look at what you design.

  • @davidpollock2245

    The chargeverter does not “clean up” the sine wave; it converts the AC current to DC which has no sine wave.

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  18 днів тому +1

      Correct, it does however accept dirty power and convert it to DC where there MPP inverter can not handle the dirty input. sorry for the mis-statement

    I wonder if the lift would be easier if the pivot point was more in the center of the panel frames.

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  20 днів тому

      It would definitely be better balanced, however in the winter position the bottom panel would be so close to the ground that sliding snow would block the panel and I would be constantly removing snow. Or we would have had to build it taller than it already is😜

  • @richdobbs6595
    @richdobbs6595 15 днів тому +1

    What was your reasoning for installing the panels so high above the ground? So that the pivot point was only about 1/3 the way up the panels? So that you went so tall, instead of wider? If my perc test goes okay tomorrow, I'll also be building next year in Northern Idaho. But, I can't say that I understand your design choices.

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  15 днів тому

      As you know, North Idaho gets a fair amount of snow. We are at 3300 feet elevation if I place the pivot point closer to the center it would have better balance however it would put the panels too close to the ground in its winter angle and I would spend all winter digging my array out from the sliding snow, or I would have had to make the structure even higher. Being mindful of how much snow will shed from your solar array is key to producing power in the winter months. We hope your perc test goes well.

      @1KGoffgridhomestead maybe if you have time make a video about the lower idle consumption of the newer inverters vs the older inverters. Lithium Solar did a video and I think his new inverters that had idle consumption of like 110 watts/ hour each. That is one server rack battery each 24 hr.

    Why are you guys adjusting them to 70 degrees? The reference chart I use shows, for this time of year and in Northern Utah, to be about 32 degrees.

    • @1KGoffgridhomestead
      @1KGoffgridhomestead  16 днів тому +1

      Northern Utah is closer to the equator than northern Idaho, so your angle would be different. Technically, for our location it is 18 degrees or 72 degrees depending on where you measure the angle from.

  • @user-ei3ml8jo1s
    @user-ei3ml8jo1s 19 днів тому +2

    The cross braced wooden substructure is not the concern. Each set of panels is only supported by 2 bolts through the unistrut that are in single shear. It’s not clear whether or not the pivot points are also single shear. As a Mechanical Engineer this structure was a great teaching moment for my students on not what to do.

      @user-ei3ml8jo1s 19 днів тому +1

      @@1KGoffgridhomestead at a minimum all pivot points should be double shear. When one of the pivot points lets go, the panels will then see torsion forces and crack them. You currently have many single point failures that will result in panel loss. It would be challenging to fix the lack of torsional rigidity on your current design so eliminating all those single point failures is your best hope.

    the "dirty" power you refer to from the generator is also known as modified sine wave, an inverter generator produces pure sine wave power that your inverters will accept. campers learned years ago to use inverter generators to protect the electronics and appliances in their campers. most home owners still use modified sine wave and get away with it and only discover the issue when they have to pay for a new fridge or big tv that gets damaged by the dirty electricity from the gen. i know there will be many that say they have used dirty gens and never had a problem but if you actually do some research you will find out for yourself what is factual.
