    Such a system need not ever face all directions. Rotating cones would only need max 180 degrees coverage, and non-rotating would only have to span winter to summer variations of sun exposure.

    Try this - Kit Carson Cooperative Community Solar: Community Solar, Solar Farms, Solar Gardens, Community-based Renewable Energy


    On the right side of the page about the middle - you will see live production updates that rotate between about 5 locations. The one in Taos, NM is 420 panels @ 235w per panel and went on-line in Aug/Sept. I'm purchasing 12 panels. Kit Carson electric rates are fairly low - about $0.105 per kwh and I don't think they have yet implemented a tiered billing structure.

    I am convinced that in the long run, we need both as it shows to be the most cost-effective solution.
    The larger the grid the more time variance over it's geography. Helpful to balance temporal issues? (NY needs power for lighting while HI is in full sunlight in the PM, and vice versa in the AM)

    Yes it helps. But the cost is significant.

    Germany currently discusses to add 3-4 grid lines running north-south to transport wind generated electricity from near the north sea shore to the industrial centers in the south. Power companies an politics try to make rate payers foot the bill, while there is resistance from people doubting the wisdom of this undertaking, and the environmental impact.

    As of today, power generation and consumption is balanced within several subgrids across Germany. You can accomodate more renewables by extending distribution, or storage, or both.

    IMO distribution only will not work, we need more storage, too.

    I haven't tried the site for my region yet but I thought I would throw this article out there for those who live in regions served by the tool they are talking about in this article ...

    1,000,000 houses in Australia got solar systems installed. It is more then 10% of houses out there!

    1,000,000 Solar PV Systems Installed In Australia! | CleanTechnica

    Small problem thought, because of the way incentives were structured in the past, installed PV systems are relatively small out there, just slightly more then 2.4kW on average. Nevertheless, looks like a great start for residential PV systems. And now Australia is attempting to work out solution to allow/promote bigger solar PV systems.
