    looks like a big ad...
    Australian site didn't recognize Sydney Australia as a location.

    Heres on that works with few ads, it will calculate without sending email address.

    It will just calculate your energy use.

    Then you can use the info at PVWatts to figure out your exposure and do some math. It works for most of the world that shares data.

    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.
