    Just a general discussion about how Solar Power for off grid living works.

    I'll start off by saying that most systems are either 12V or 24 volt systems.

    Some things to talk about are MPPT Charge Controllers, Power Inverters, types of batteries used for a battery bank to store the electricity that will be used when there is no sun to charge the solar panels.

    Google? What the F*#$ is a Google?
    How can a website deliver thousands or millions of pages of returns on ANY topic my little mind can imagine? Is it like magic or something?
    How do they do it?

    Edit: Original post this response is aimed at has been changed to something quite reasonable sounding now! We now return you to the original thread already in progress. :)

    Plenty of devices/appliances can. My kettle, for example, handles 2000W. Many industrial motors draw >65A. Transformers or switch-mode-power-supplies (SMPS) convert 120VAC or 240VAC to lower voltages, if necessary, for low power appliances such as your 5VDC phone charger.
    They index the whole of the web, and use clever algorithms to match search queries to indexed web content.

    LOL. You're probably more clued up about US politics than I am, so you tell us :).
    Personally, none. How many do you have?

    It seems that this htread is consistently going nowhere...but going. Keep it alive, please!

    BTW, this kettle is able to handle up to 40 KW

    Off-grid will need lots of batteries. I started down this road a few years back and testify that the peripheral equipment requirements of off grid electricity generation are going to cost at least as much as the panels and probably much more.
    that being said... using them for feeding the grid with excess power is the cheapest route into the realm. Really helps in those cases where the utility allows sell back values equal to user rates.

    Solar power is the best option for the off grid ones. Electricity generated from solar energy can be stored and used later when there is no sunlight . Many renewable energy provider companies are working on the solar technology to provide us us newer and better solar gadgets.

    I currently use a solar powered clothes dryer. Have been for years.

    My mom was very fond of her solar powered clothes dryer.

    Nothing else makes your clothes smell fresher!

    Depends where you live. Some places, you just provide a home for mold and mildew.

    Some that live completely off grid use both solar power and wind power so that, when one isn't providing energy , the other may be.
    For either or both you need a lot of storage batteries to store the power for when it's needed, probably a few tens of kilowatt-hours worth.
