    I like this guy because he shows that there are alternate ways to set up your panels and save money.

    Let's go off grid.

    https://www.youtube.com/watch?v=udF3xG0TQ54

    Thank you very much, bobhardee, for sharing the practical side of living off grid and technical insight "on the spot".
    The talking in this video is pretty fast and real "workman's talking", for me at least. It seems they all know what they're
    doing pretty well. That's new to me Wink

    I don't mean that in a bad way, it's just coming out as it pops up, my writing, most of the time. Although I'm my own critic.
    I've never seen such a video with all that technical know how and phases that go from day one to day two, etc. etc.
    I had no idea how much technical stuff and material this involves, to make it work. I mean the solar panels heating
    water in the house and the pool and what not in pan and pot.

    It's very unusual to me, this presentation, it's like looking at a fast forward movie of a procedure, for I've been for half
    a year in sustainable communities, living more or less off grid in a completely different way, compared to how it's shown
    in the video. Mostly the location was so remote, that even the choice wasn't present to live off grid Wink Just like living in the
    wilderness. Many communal members had little money to invest in machines and material, or they had lots of it, but were
    afraid to use it for uncertainty about old age and in want of living in freedom. Some were in fear of failure and in doubt for
    success. I've been very amazed, by residents telling me that they had no idea what this way of life would involve.
    They just chose to step "out of the box" and leave a life of nuclear families, as they call it.

    If you're interested and give yourself a chance to live for a year or so in such communities, you will find that we're all pretty
    much the same, off grid at home, in electrosmog, online or offline, in our eccentricities, quirks and originality of shine, dine
    and wine. And doubts with endurance, couraging and inventive fouraging. Some community residents choose from principle,
    to not invest money in an off grid lifestyle, wanting to meet challenges in finding solutions and inventive use of electricity,
    created by a fast flowing stream, downhill, like in Lammas Wales. Or a windturbine high on a hill at Landmatters Devon UK.

    I've witnessed a witty and clever young father, a former US Mariner, turning 180 degrees to Esalen, meeting the love of his life,
    both wanting to live free. Now he's building the familyhome, a strawbale roundhouse. With a powertool on batteries, to screw
    the screws in. With help of volunteers, like me, in 2012. Seldom had such fierce arguments and good fights Whistle working
    it off in a good way, while laying the roof with grassclumps in constanct rain. Cheering with a beer at a fire in the night.

    Most technical construction is done in the "old fashioned way" by hand and non-use of electricity, mostly. In Lammas Wales,
    I used a washing machine, working on that wonder of electricity, almost electrocuting me, for it stood in a pool of water in a
    derelict shed. Now you may understand the shortcircuiting, why I seem a bit off grid up above, at times Lmfao

    Most of the residents I met, gather all kinds of 2nd hand wood/iron material, scavenging at derelict housing sites and
    container content, scrap heaps of industry regions. NEVER throwing away ANYTHING. After 5 years, until this day, the
    family living near that handmade roundhouse - to - be, still uses the caravans that are glued together, as their living space.
    The family uses a polytunnel as eating space, when volunteers are around, it's also a playground for their 3 kids.
    The mother needs to practice great patience, with her kids, the father wants it to be exactly as he wants it to be.
    AOUMM Cup o Candle in the Wind Earth Water JT and now and than Gathering and:box: Brrr Sabina

    I've seen many inventive ways of making things work, in housing and practical solutions for cooking and warming
    a home. And I know that people sometimes live in dire circumstances, specially with small kids, the choice of school.
    Some residents have a beautiful dream but no skills and they have to start from scratch, pun double intended.
    Some reach high skies and high fives in their endeavors and some are stepping back from such a life, frustrated.
    I know of a woman I met in one of the communities, who's pretty wealthy, in money, but very scared for being
    abused and misled by strong workmen who could do the job for her. She's a woman who can't sort out her priorities.
    I've been helping her to make friends with her neighbors, by asking them for help.

    She's been on a seasaw of pondering and doubting, trying to build a self-watering polytunnel and a vegetable garden,
    caring for ducks and slugs, although not with enthousiasm for the latter Bleh trying so hard to make things work for her,
    that she now suffers a heartcondition and slowly comes to a conclusion. She's an intelligent woman, very educated and learned.
    She told me once that no matter what would come of it, the choice to make that step and live in such a way, was the best
    choice in her life. I think she's ready to write a book, having made such efforts to create a free life, finding also her challenges.

    For those of you who are new to it and like to read the journals of my volunteering in more or less off grid communities,
    please visit www.theartofcare-net.webs.com It's been a 2012 break in my membership here, moving from BroomBroom
    to B.B.Baghor.

    That place where you live must be a great place with incredible benefits. You could get great ideas from neighbors on how to make things work. You get to work together and really connect with others. You are using earth friendly material and building strong so things will last. With different resources available, it becomes more a question of which one of the technologies you wish to use...be it wind, water, or solar. It has got to be an amazing place to live...and it sounds perfect for you.
    The price of solar has continue to come down so that it is really getting practical to set up your own solar system. In the USA, most of the electric companies will install a meter that runs backwards. It's so that the power that you don't use at the house will go out on the grid. It is a way to make money....or at least bring your power bill down to virtually nothing. It depends on how many solar panels you have working and how efficiently they work. I know of one man who made a solar tractor for his unit and it increased the output by 20%. (Search SCEG solar).
    There are solar farms up in the mountains. All of these are feeding the grid so that the owners are making money on how much they produce. South Carolina doesn't have as many energy incentives as North Carolina and thus it doesn't have the number of energy farms. However, we are on the up and up. Oh and by the way, the reason the man on the video sounds funny is because he is from down south. (like me...only to me he sounds normal.)
    There are a number of things that will need attention on the log house (heat pumps replacement, new flooring, window replacements, and a hundred little things) before we will get around to solar but one day my dream is to set up as many panels as possible so that we have a mini solar farm.
    Carol:
    Glad you are enjoying them.

    Thank you, bobhardee, that's a beautiful way of looking at it, the benefits on many levels, in such a way of life.
    I have found great companionship and humour, endurance and rubbing of shoulders too... yes, perfect for me Wink I live in
    a large old university city Utrecht, in Holland, for 23 years. My volunteering was in 2012, of which the journals are present
    on that website. I'm making my move overseas, this year, returning to one of the regions where I've been in 2012, as a
    volunteer. I have enjoyed and still do enjoy working in such places, creating a home as a living being, sort of, at least a
    stable one. I'm sure I love my privacy and choice of being in company or not, no shared living space all the time, for me.

    Connecting with others can turn out a bit nasty too, for it's true that there are "rampant individuals" present in such places too.
    When working in one of the communities, during that half year, I was told that a certain member had killed a cat and had hung
    this animal on a thread, at the house of another member, during a mutual overheated argument. Some also have guns and roses.
    I've never felt in danger or threatened by people, in these kind of places. I'm not inclined to an intense creation of drama.

    The only danger was in that washing machine at Lammas. The owners of the place, finding my note on the machine, in shivering writing,
    returned one much later, saying "We'be been very concerned about you, but fortunately you survived" Blink These are the owners of the
    land of Lammas, which has been a sheepfarm. This couple lives in the farm and offers rooms for volunteers. I was staying on the plot of
    residents, at Lammas. Without knowing them, me a newbee volunteer, I walked one day on the path along the woods and the pond.

    A group of people approached on the other side, talking. One of them, a young woman, walked towards me and said, while looking me
    sternly in the eye "Do you know that Jesus loves you?" I instantly replied "Yes, I don't need you to tell me that" She was stunned to silence.
    Such a laugh... uhhmmm, life, I mean. Lmao

    For the time being, as far as the Cosmic Weatherforecast, now
    more near planet Earth, the wild wind does make itself heard inside my home.
    Tall trees and large trucks fell today, in Holland. Much dead wood came down
    from the trees, everywhere. Springtime cleaning in nature Wink
    The weatherforecast here says windforce 6, but it's much stronger,
    when you're present in it live. Hanging in there.

    Regarding Lammas, which is in Wales, I'm not sure if I will go there.
    I'm looking forward to visit the community for a day, once upon a time.
    When I make my move this year, I'm going to share a home with people,
    in Devon or nearby Devon and first grow familiar with leisure time all the time
    And the area, enjoying the sense of being at home on that island, every moment.
    And that there's no end coming nearer, like in the 15 years monthly holidays, spoiling the fun Cheerful

    There are a number of videos out there on this subject. Finding one that is worthy of sharing on Mists is not as easy.
    This person shows a simple off grid system that is affordable and easy to install.

    Even though the information is basically the same, this is a Brit talking about wiring an off grid cabin somewhere in Europe.

    Not sure that I would run a wire from the solar shed to the house like the man did in this video. I think it would be a really good idea to ground that baby and put that wire in the ground.

    Living Off Grid: Our Solar Power System

    3/16/2012 12:54:45 PM

    By Ed Essex

    Tags: off grid, living off grid, solar power, solar, Ed Essex

    Solar Power has come a long way in the past decade or so. We are living proof of that, after all, what did we know about solar power or even electricity for that matter? Yet here we are in our second full season, living off the grid with solar power. Systems today are so sophisticated they run by themselves and the only thing you really have to worry about is battery maintenance if you have a battery storage system as part of your package.

    While I am sitting here telling you that modern solar power systems are relatively hands free, I don’t recommend that you operate them that way. I believe you should get as involved in your system as you can. For me, that meant there was a lot to learn and it has taken some time to do so.

    PanelsMy system consists of 8 each 215 watt REC panels on a fixed position steel pole. The panels were recalled by REC, rebuilt and put back on the market at a discounted price. My inverter is a Xantrex XW 4024 with an automatic generator start control module. My charge controller is an Apollo T-80 HV. I also have 12 each Solar One 2Volt batteries for a 24 volt system. My backup generator is a propane fueled 12,000 watt Kohler Residential outdoor unit. I bought this unit knowing Kohler wouldn’t warranty it for off grid use.

    The system capacities are as follows;
    Panels - 1720 Watts
    Inverter – 4000 watts
    Battery Storage – 1160 Amp Hours or 22 Kwh Storage which means about 3 days for us because we don’t like our batteries to go below 60% capacity. (I actually don’t usually let them go below a 30 percent discharge or 70 percent capacity).

    Inside the house we have a Trimetric Reader that allows us to see what our electrical usage is at all times and what state our battery capacity is at. It also helps to track how long it has been since our batteries were charged to 100% and how long it has been since we equalized our batteries which for me has to occur once a month.

    Our system will run our house, barn and 220V water pump for two people easily. When the sun shines it produces more power than we need. The only reason we have the backup generator is because the sun doesn’t always shine. You could have as many panels or as much battery storage as you want. No sun, no power. We use our backup generator about 100 hours per year.

    Total cost of this system was about $22,000. The current Federal tax code allows for a 30% credit so we only ended up paying $15,400 for our system. Our panels are warranted for 25 years and the batteries should go at least 10 and up to 15 years.

    If there was an electrical source for power at the edge of our property it would have cost between $14,000 to $19,000 just to get the power from the road to our house and then you would have a monthly power bill on top of that.

    So in our situation it cost the same amount whether we brought in power or installed solar power and with solar, there will be no monthly bills. The decision to go solar was easy.

    Power SystemAs I mentioned earlier, these systems are almost hands free if you want it to be that way. You can program your inverter to “run” the operation with no input or help from you. The only thing you would have to do is maintain your batteries.

    In our case, with our preferences, the inverter would do the following:
    Allow the panels to charge the batteries to 100 percent. Once they reach 100 percent the inverter switches the charge controller off except for just enough power to keep the batteries tweaked at 100 percent. If there is no sun, the batteries will discharge to 60 percent capacity at which time the inverter will turn the generator on automatically, charge the batteries back up to 100 percent and then turn it off again.

    That’s the simplest explanation I can give you about how sophisticated this equipment is now. It could manage the whole charge/discharge/ charge process if you wanted it to without you ever lifting a finger.

    I don’t allow my system to do everything automatically. I keep my panels tilted in the most advantageous angle. I start and stop my generator by hand. By doing that and watching the weather reports pretty close I can squeeze a few more amps out of my system for less time on the generator. It also helps me to keep an eye on things like battery temperature, water levels and equalization. I also decide when my water pump goes on. It is set up on a float system and would pump automatically but if I see that we can reach 100 percent battery capacity first and then pump water because we are going to have sun for a few days I may delay the pumping until it’s the perfect timing for my battery condition. All of this participation results in you becoming more aware of your electrical use and that ultimately results in less power used.

    As stated earlier my system totaled about $22,000. I had other quotes ranging from the same price with different equipment (different design), to $37,000 and $45,000. That’s a big difference. It pays to shop. We had this system installed for us. If you live in Washington State or Idaho and would like to talk to the licensed person we used you can reach me through either website listed below and I will be happy to put you in touch with him
