Used Solar Panels are a great solution, but not in the way you think.
According to a world price survey, solar energy prices have decreased an average of 4% every year for the past 10 to 15 years. There's a progressive increase in conversion efficiencies of cells, and producing economies of scale are the fundamental drivers of this price decrease. The Solarbuzz worldwide Price survey clearly indicates that costs have consistently declined for over the last two years. An exhaustive research into the worldwide photovoltaic market is present in on the the number one industry reports, the Market Buzz 2009. A residential solar energy system typically costs in the region of $8-10 per Watt in 2009.
Some guess that these types of solar arrays can produce twenty five percent of the world's energy wishes by 2050. It is expected that the cost of CSP can become as low as 6-7 cents per kwH, as low as conventional energy production. The CSP industry is growing quickly in Spain and the U. S. , and the SEPA is tracking over five thousand MW of new project press releases that are slated for development until 2015. Only a few of them will be built ; permitting, financing, technology and other considerations need to fit into place first but the industry is balanced for rapid growth without reference to any individual project's outcome.
Domestically, the US market for PV is predicted to be around $27 billion dollars by 2020 according to the office of Energy, and immediately and indirectly create 150,000 new roles. Practically speaking, solar energy also allows nations without a grid infrastructure to power isolated areas, and people to power their own home independently, constantly receiving a free source of energy from the sun. Even in the U.S, distributed transmission lines and autonomy of energy sources is becoming more critical due to aging infrastructure and local emission restrictions. These generate 75 kW of energy and this solar panel array is predic ted to pay itself off in 5 years.
Solar power is not subject to political risk, and it is not possible for it to be blocked. This can also be considered in other nations, like Pakistan, India, China, and even the Saharan Desert in Africa. It is worked out ( from a Rice University whitepaper ) that it would probably take 25000 square kilometers of solar panels to supply all the U.S. Electricity needs for one year, and there's certainly this amount of land available in the united states. In fact, more land is getting used to grow ethanol now. I am expecting that inside 30 years, solar power will become the dominant energy source in a lot of the developing world and the united states.Used Solar Panels
