Wind And Solar Prices Keep Falling

As the economy sputters back to life it might make sense to start looking to add solar and wind power to your home and business.  Prices for both wind and solar have nearly dropped by 50 percent since 2007. Wind turbines are off by one fifth and solar panels are down fifty percent.  Even though wind turbine installations fell in 2009, the rest of the world added a record amount of solar panels aided by generous incentives in Europe.  The price of solar panels is expected to decrease by another 10 percent in 2011.  Even the cost gap between using wind or solar versus coal power has narrowed.  New solar and wind fields can now generate electricity at a cost of 6 to 8 cents per kilowatt, while coal comes in at 3 to 7 cents.  The cost of building a wind or solar field is much less than trying to build a new coal plant.  Emerging countries are flocking to build solar and wind power plants instead of coal ones because of the ease and cost factors in putting them up.  Wind turbine fields are quicker to install than any large coal, gas fired, or nuclear power plant.  Prices for wind and solar are expected to continue their slide because of worldwide increases in manufacturing capacity.  Now could be a great time to look up your local solar and wind installer and get a quote to help you get off the grid and in lowering your own carbon footprint.

  1. Sorry to say this but some of what you said is inaccurate, even deceptive.

    While the price of solar PV panels and wind turbines is falling, they are only part of the cost of a grid tied installation. Solar panels are now less than 50% of the cost of a home installation. These other costs also need to be addressed.

    The cost comparison between coal and solar is not really relevant because coal provides baseload (24/7) power and solar PV is intermittent providing, at most, 25% of the rated peak output.

    And, this leads to the myth of being “off the grid”. If you have a grid tied system, you are not off the grid. Even if your electric bill is $0.00, you are still using grid power part of the time and the gird is not a battery.

    There is a limit to how much wind and solar power that can be installed before we run into the fact that wind and solar can not provide baseload electric power.

  2. James one of the issues I advocate is the need to add more solar, geothermal, ocean wave, and wind to our efforts to reduce our dependencies on coal and oil. Price reductions to components can encourage a greater use of greener energy tech. My own company has five plants around the U.S. 60% of our entire electric needs are taken care by our solar panels. They do work on cloudy days, and on weekends when our plants are not running they are kicking power back into the grid.
