According to a worldwide price survey, solar energy prices have decreased an average of 4% every year for the past 10 to 15 years. There is a progressive increase in conversion efficiencies of cells, and producing economies of scale are the base drivers of this price reduce. The Solarbuzz worldwide Price survey clearly signals that costs have regularly declined for over the last two years. A residential solar energy system usually costs circa $8-10 per Watt in 2009. Without inducement programs, solar energy costs range between 22-40 cents/kWh for large PV systems.
Another system being used for enormous power stations is the concentrating solar power ( CSP ) technology, this is a massive array of mirrors or lenses that are focused to either produce heat, or directed to PV systems. These are built at a price of $2-$4 per Watt. Some guesstimate that these types of solar arrays can produce twenty five percent of the world's energy wants by 2050. It is expected that the price of CSP can become as low as 6-7 cents per kwH, as low as conventional energy production. Only a few of them will be built ; allowing, financing, technology and other considerations need to fit into place first but the industry is balanced for fast growth irrespective of any individual project's end result.
Solar energy already has a tremendous effect on the global economy. Domestically, the US market for PV is predicted to be around $27 bn. bucks by 2020 according to the Department of Energy, and immediately and indirectly create 150,000 new jobs. Practically speaking, solar energy also permits nations without a grid infrastructure to power isolated areas, and people to power their own home independently, consistently receiving a free source of energy from the sun. Even in the U.S, distributed transmission lines and independence of energy sources is becoming more critical due to aging infrastructure and local emission limitations. As an example of energy independence, Hawaii's Mauna Lani Bay Hotel's installed PV cells on its large rooftop. These generate 75 kW of energy and this solar panel array is predic ted to pay itself off in 5 years.
Solar power isn't subject to political risk, and it is impossible for it to be blocked. This can also be considered in other states, like Pakistan, India, China, and even the Saharan Desert in Africa. It is figured out ( from a Rice University whitepaper ) that it would take 25000 square kilometers of solar panels to produce all of the U.S. In fact, more land is being employed to grow ethanol currently. I predict that inside 30 years, solar power will become the dominant energy source in a lot of the developing world and the US.
