  •  Careful with the figures on solar. (6+ / 0-)

    Solar prices are dropping so rapidly that figures on the cost of solar are badly outdated within a year.

    In Germany, the feed-in-tariff rates for solar currently are between 13 and 18 eurocents, with the low rate being paid for large-scale, free-standing solar parks and the high rate being paid for small scale rooftop systems.  For those systems to be profitable the actual production price has to be lower than that by a few cents.

    So, with large scale systems in often cloudy Germany the LCOE for solar already is down to about 11 to 12 eurocents.  The only  systems that still cost up to 21 U.S. cents a kwH are the small pv systems on the roofs of homes.

    •  Right, that EIA study used 2009 prices. (3+ / 0-)

      And solar and wind are both trending down, will do so for the long term, while the down trend for nat gas is a different situation, a more mature market.

      Wind is just coming of age in the market place, solar will soon catch up and likely pass wind by the end of the decade, Re: LCOE.

      IMO Thin film, when it hits 20% efficiency it will take off. Magnolia solar did 20% in the lab 2-3 yrs ago, currently IIRC Magnolia sells thin film at 10% eff. GE at 12%.

      My gut says that if thin film can start to generate early in the morning (eastern facing windows), and western facing windows can generate later in the evening, maybe thru 7:30pm. The potential for thin film to open up the generation window for solar, from 10am-4pm to 7am to 7pm just makes solar an even better match to demand.

      And with regular PV moving up in efficiency (Spectrolab 39%) solar will soon break out like wind is now and start to attract more capital. Then solar and wind will be the cheapest, and start pushing everything else out of the marketplace.

      •  Oh yeah, 2009 is incredibly outdated in regards to (3+ / 0-)


        If I remember correctly, the price for solar systems has been halved in Germany in just the last 3 years.

        Yep, thin film is really coming along.  Oerlikon has 12% silicon thin film modules already and they perform far better in cloudy conditions, when hit with partial shade, and in hot climates.  These types of modules are great where space is not a big issue.

        Wind basically already is the cheapest, after hydro, in many parts of the world and, as you say, solar is decreasing in cost at a rapid clip.
