    Around here, average for those numbers would be something like $3.10 per watt, 1.5kWh per watt per year, and we're assuming 25 years.

    $310/1.5/25 = 0.083

    I can't imagine that you'd have to pay $3.10/W to get the panels dropped in your driveway. Should be around a dollar, with the new tarrifs, depending on how high end you want to go. Inverters and racking shouldn't cost you more than another 50 cents for a 10kW system. If you're an electrician, ask around at distributors instead of scanning the web.
    I missed that you were quoting per kW-hr, not kW. I was looking at cost per installed watt.

    Agreed.
    Utility scale storage is a point I have brought up here and other "green" forums.
    Hydro is a renewable with storage.

    But the lack of storage is no reason to assume that solar and wind cannot be valuable contributors to the mosaic which is the energy picture of the present and future.

    Agreed which is why I would make no such assumption.
