    The installation of my 7KW array on my Garage roof was just completed. I have made the transition to energy and transportation systems all made in US and run by the Sun. Now I can run my American made Ford Focus E and Tesla S on energy made from Washington manufactured solar panels. I am the oil companies' worst nightmare. Ha Ha. I can't wait till more people start kicking ICE and big oil to the curb! IMG_7303.JPG

    Awesome, that’s an impressive size for your solar array.

    Yup - here's our 10.1kW solar PV array:

    It is a wonderful thing!

    Beautiful. That’s more than double my 4.5kw install.

    The first solar panel is the most important.

    The reason there is staging (and an electric hoist!) is that my brother and I completely removed the old hip roof, and then framed the new gable roof - so we could fit this system on the house. We cut down 3 trees to open up the sun exposure.

    It is 10kW AC which is at the limit for a residential system here in Massachusetts. (We get 100% net metering credit - over that and it drops to 60%.) Since we have two electric cars (Bolt EV and e-Golf) and we have a mini split system (the outside unit is on the lower right of the house, and some of the conduits are on the south wall), and we have a heat pump water heater - we use a LOT of electricity. This solar PV system looks like it will offset about 75% of what we use, so I hope to get the limit raised; by say 1kW per EV you own, or 2kW if you use mini split for heat. If the limit was 15kW, we would be fine.

    I would add panels on the east and the west, to increase the production in the early morning and late afternoon.

    Love it ! It looks very integrated to the design of the house - yes

    this is not exactly what I want to do, but is in the path...

    a vehicle that generates its own energy... dinpensing any recharge point

    Right - it takes about 24 panels (like the original poster's system) to charge an EV. And you would have to have them in direct sunlight for 6-9 hours. So that kinda puts a sharp point on the issue.

    You would park all day, and then drive at night. And carrying 24 panels is nontrivial.

    well neil, good day
    my project is put 15 panels 300 w, 5 fixed and more 5 on 2 sliders, opening when parked
    this will take 8-12 hours to complete recharge... but in a motorhome the time is less important
    I want travel not all days, but each 3-5 days, sometimes each week
    and you know the sun in brazil ? strong
    but a great motivation for this project is avoid the home rent, the energy bills, and the gas cost

    and a solar collector for heat water for bath, and a solar owen for cook (a microwave for sometimes)
    I am SF writter, each morning I awaken with a idea, depending on I write a lot, I can park many days on each site, so the recharge is secure
    I am trying get the money for begin, maybe I could launch a crowfunding for it, and after I will publish all plans for others enjoy

    I Now have the whole project, for the electric motorhome, it generate its own energy. 15 solar panels on the roof, 5 fixed and 10 on 2 sliders, opening when parked. including for whom lives outside tropical zone. As the economy for now is hard here, i want sell the plans, i will send the details and specifications for whom pay me only $40, reply for details

    I believe that putting a set of panels on the roof of the house is a good solution, for those who live in a fixed house in the city, and have their short daily commute to work. is the reality for most, no doubt.
    but for a growing portion of people who have decided to live in a smaller place, either because they have less money or to relieve stress, or have adopted an itinerant way of life, there is always a more adequate solution.
    if the person can take with him a set of panels with their support, and these panels are in sufficient quantity to supply energy to the traction of the vehicle, plus their daily activities, it creates a way of life of adds to the use of electric vehicles, this new way of life that is becoming a solution for those who want to add quality of life and low consumption, sustainability and pleasure.

    I have a project for mount an electric motorhome, where the energy come from a set of panels on roof (5 fixed, 10 on 2 sliders opening when parked); when need recharge I search some good place for wait 8-12 hours.
    But my project is stopped; the situation here in brazil is getting hard to raise the money.
    So, I want sell the whole plans of the project; I will send a set of detailed plans for whom pay me only U$40.
    With the money, I will launch a marketing campaign for my SF book, so when I get about $120k I will begin the project; when finished I will publish a video showing the vehicle and it´s characteristics.
    With this vehicle, I will get avoid not only the gas cost, but also energy bills and home rent. In others countries, the situation can perhaps look as here; the temptation for surpass this is very strong. I have now the whole project, including for who lives outside the tropical zone. The vehicle dispenses then any recharge point, allowing stay long terms on remote places, perfect for camping or long travels. A vehicle that besides serving as a house also dispenses the energy bill and the periodic visit to the fuel station... considering the rise of fuel and electricity, it seems increasingly tempting.
