    Does the system store energy for use @ night? Maybe overly paranoid, but I was thinking about it more so for the doomsday scenario if the grid went down than being green although at least still some benefits there (maybe) and not totally throwing $ away even if not the best investment and I'm assuming no need for a generator even for a temporary power outage. The grid going down may or may not be a real possibility (?) and if it did, not having electricity may be among the least of the problems, but...

    They said the battery technology is just not there for this to be a reasonable cost efficient option. They could offer me a 10Kw battery system and the switch gear to make it work but we would be limited on what would and would not run in the home. I'm pretty sure I can come up with something as good if not better for less than the 10 grand asking price. The rep advised to keep my back up generators on hand for the times when the power is down for extended periods. We recently bought a 16000Kw generator that will be powered by the PTO on our tractor. @ 1800 rpm(540 pto speed) it will run at 1/2 gal an hour.

    Id be more worried about thieves trying to steal the equipment off the house or worse and having lights on at night would be a sure beacon to dishonest people out there.

    I was under the impression that, even with some kind of power storage system, you use what you produce during the day and run off of the grid at night. Doing this still produces an excess that the power company repays you for and provides power on those days when you are producing minimal power of your own (rainy days, foggy days, etc). I would think that not having a means of storage would be considerably cheaper than buying a technology that is not quite up to snuff yet.

    I don't know anything about it, but I thought Tesla just came out with batteries for doing exactly this. If the energy storage code could be cracked, there would practically be no need for a generator and one could nearly run off the grid in perpetuity if need be. IIRC, there's a solar wrap developed or being developed intended to wrap an electric vehicle, but it all comes down to something revolutionary on the storage side vs. the incremental improvements on the current technology. Just think how many Buicks one could buy if they figured out a new technology:). I remember when RAM was $40/Mb and inkjet printers were $500, so it'll happen sooner or later.

    Im looking into refurbishing old fork lift batteries. I can get them cheap and they have a lot of capacity. Recently installed a A/C system for a house that was "Off Grid" and the biggest concern was starting draw on anything electrical.


    I think you are exactly right. Also believe its not far off.

    when it comes to profitability it would be good to know whether you can do net-metering (big issue in many countries).
    Florida should have enough irradiation that repay periods should be well below 10 yrs. now. Can you buy PV systems and plug them into your system or do you need somone else install them?

    I now have a install date for the 29th of Nov through the 1st of Dec. !


    Patrick, I believe this is not to big of a job but requires state license and permits to do the work. I've really been thinking about starting a solar company myself. I'll be watching very closely and asking lots of questions while the crew is doing its thing. Later after its all done and running I will purchase more panels myself and add to the system. I've got no shortage of roof top or sunshine.Will post pics of the progress when it gets going

    Briz,
    In some European countries they have now approved systems, consisting of 1-3 modules, inverter and a common electric plug that you can plug into your household socket, like any other household appliance. So no need for electrical engineering capabilities and your capex come down further ;-)
    I wouldn't be surprised if these kinda systems were available in the US as well.
    photovoltaic will stir up the energy world big time.
