Solar Energy Phones
Solar energy phones are bound to become the must-have product in the future. As the energy reduced daily, energy saving is an eternal task. The current cell phones are almost use lithium, Ni-MH are all energy consumption, environmental pollution and difficult to recover. I strongly appeal majority people who with social responsibilities pay attention to this industry’s development.
The differentiation competition urge the cell phone emerge one after another, such as business cell phone , information security cell phone, invisible cell phone. Recently, a new kind of light energy cell phone shocked this area and attractive enough eyes. Explanting solar energy technology to cell phone has enormous appliance value? What is the technology difficulty? And whether it is becomes to the new sea of cell phone industry or not?
Plenty of consumers’ cell phone always out of battery, so many people have to take along 2 or 3 batteries when goes out, even someone take along the charger daily. Solving cell phone standby problem is concerned by supplier all along, along with the come forth of cell phone multimedia function, standby problem disturb the Solar panel cell phone industry and consumers all alone. Everybody hope to explants convenient, energy saving, safe and reliable solar energy technology to cell phone, make it becomes to the long-term steady dynamic supporting of cell phone in 3G eras wireless life?
Users obviously feel that the charge frequency reduced dramatically after they use the cell phone battery which utilizes the solar energy technology. The battery working life increased obviously which convenient to people phone conversation, media and entertainment aspects. Meanwhile, new energy, new material is the inevitable trend of cell phone development. Photo-electricity converts technology full of challenges.
Current domestic chips enterprises is in weakness stage in photo-electricity convert chips and low consumption chips technology, it is difficult to achieve mass production, hence, it is difficult to realize domestic purchasing in a short period. Besides, some domestic solar energy monocrystalline silicon wafer company supplied solar energy silicon wafer with low absorptivity universally, it will affect photo-electricity effect directly. Now many laptop battery manufacturer are using the solar panel to design the new battery accessories.
How to increase the solar panel use area under the circumstance of not affecting the cell phone cosmetic, optimize the battery internal management and enhance the photovoltaic conversion will be the further focus and difficulty in technology development of solar cell phone. Now the solar panel can be used in laptop battery.
China now has more than 400 million mobile phone users with huge potential consumer market. In addition, this technology expect to realize on mobile phone, but also can be expanded to MP3, DV, DC, Bluetooth and other consumer electronics products, the application value is very wide. With gradual growth of market and increased feedback of consumer satisfaction degree, solar energy cell phone will be like a webcam as an important standard device of cell phone and become as a guideline for consumers to choose cell phone. Experts predict that solar energy cell phone battery will be a bright point next year.

Interesting news from Market Watch - Given the size, population, resources, and level of technology development in the United States, the US solar market is believed to be the most underexploited in the world. The US solar market has experienced fantastic growth over the last five years.
As part of the Emergency Economic Stabilization Act of 2008, the U.S. Investment Tax Credit provides another eight years extension for commercial and residential investments.
Trends in solar thermal power revolve more around mandates and financing than technology, thus the ITC provides the necessary financial support to ensure the growth of this emerging technology.
Within the solar market, solar thermal (concentrated solar power) installation is expected to surpass those of solar electric (photovoltaic). Research indicates that utilities firms are looking at solar thermal as the preferred alternative energy technology.
Solar thermal energy presents a more cost-effective way to reduce dependence on fossil fuels and meets the renewal portfolio standards (RPS) that call for a certain percentage of renewable energy by a certain time.
Standing to the online report available here
U.S. Southwest has the highest amount of sunshine and open land, resulting in numerous suitable sites for solar thermal power plants. According to Abengoa Solar, U.S. southwest can support over 11TW of solar thermal, which is enough to support a capacity of more than 6 times the current electrical demand in the United States.
In the southwestern United States, the cost of electricity from CSP plants (including ITC) is about 13–17¢ per kilowatt-hour, meaning that CSP with thermal storage is competitive today with simple-cycle natural gas-fired power plants. The U.S.
Department of Energy aims to reduce CSP costs to 7–10¢ per kilowatt-hour by 2015 and to 5–7¢ per kilowatt-hour by 2020, making CSP a competitive alternative to fossil-fuel-based power sources.
