    PV-connected cooling needs thermal mass to bridge the differences in the solar insolation and building demand curves. Hydronics is the simplest, least expensive way to accomplish that.

    @ChrisJ you can do what ever you want with out power companies say so. However if you are going to go as far as total off grid then why would you want the grid?

    On another note I guarantee you don't have enough usable roof space to allow total for a totally off grid system..maybe yard open land also. Then comes storage......


    Several things.
    I never mentioning going totally off grid, the point was to sell back electric while you can and not have to store it.

    Second, how can you possibly make a statement like that, knowing close to nothing about me? For all you know I've got a 12W steam boiler and an atmospheric gas water heater and a 40W light bulb in one room.

    You really know nothing about my power consumption.

    @ChrisJ you are correct that I know nothing about your KW needs. However I can assume your use around 1000kw a month from a state by state average per capita.

    Plug in your numbers in a solar PV calculator. Do it as off grid. You will be shocked at the quanity of panels, cost, and pay back time frame.

    Couple that with a PV panels degraded output over time.

    For me if I go PV it's all the way, and cut the umbilical cord. I'm either all in or out. Helping the power company create KW so they can sell them some where else where is not in my cards.

    Guerilla Solar may be coming back (see Home Power Magazine issues from the late 1990s.)

    Batteries are expensive, inefficient, dangerous, toxic, and have a relatively short service life. Low temperature thermal storage is inexpensive, efficient, safe, non-toxic, and has a very long service life. Deciding on the second investment (after envelope improvements) is hardly rocket science...

    I didn't mean to go off grid. I meant only for air conditioning powered exclusively by solar. In hot humid regions AC is what makes electric bill so bad. A solar AC doesn't need expensive interconnect with electric utility.

    Just had to run the numbers for fun. That's 0.17 EDR (before piping and pickup.)

    Oh boy. :)

    You know jolly well I was talking about my gas steam boiler.
    Never measured it with the Ecosteam, but the boiler it self uses about 12 watts.

    A 12 watt electric boiler would be cool for a toy house I guess.

    njtommy, seems from your link that Lennox is integrating solar with conventional electricity. That's extra money up front.
