This month, the Kyocera Corporation announced the launch of the Kagoshima Nanatsujima Mega Solar Power Plant. This 70 MW solar field covers an area the size of 27 baseball fields and cost about 276 million USD to construct. It is Japan’s largest operating solar field.

    This is cool… but why do people (in the loosest of terms) still put solar panels on the ground when there are so many buildings with flat roofs?

    Doesn’t look very tsunami proof.

    When average solar insolation countries like Japan,Germany etc. are harnessing Solar Energy on a massive scale why not tropical countries with maximum solar Insolation?

    Coal-fired electrical generation costs $(USD)0.05/kWh at the busbar. $(USD)276 million solar to build would then purchase 5.52 billion kWh coal to build and run, 5.52×10^12 Wh. Generously assume 70 MW average over a year (as opposed to that being peak generation capacity on 12 noon summer solstice), generously 9 hr/day.

    (5.52×19^12 Wh)/[(7×10^7 Wh)(9 hrs/day)(365 days/yr) = 24 years to break-even with zero-interest DCF/ROI, assuming no solar cell degradation and no cloudy days.

    What was that word Penn and Teller named their TV program?
