Not an area on the water

　　A few years ago, people considered the siting of solar power plants, the choice is the desert, because the desert land is not worth much, but sunny. In fact, the sea conditions and more similar to the desert, it will not occupy the land, but not the surrounding buildings, mountains and other objects blocking the sun. The reason why people do not take into account before construction of solar power plants in the sea, because the traditional solar panels can not resist seawater corrosion. However, the French and Israeli researchers developed a resistance to corrosion of water floating solar power systems, solar power plants built in the sea has become a bright future together.

　　From the current perspective of the development world, mostly located in economically developed areas in coastal cities, the population of these areas is also very intensive. In these areas to build large-scale solar power plants, and residents will inevitably compete for precious land resources . However, the vast coastal areas near the mainland no one living on the sea, if the solar power plant built in the sea, and residents will compete for both land and do not need distance from the remote areas of transmission , electric power , low cost, energy waste less .

　　Water not only the construction of solar power generation system on the ocean, you can also build in fresh water lakes, the best option is to reservoirs. Often a reservoir in the population centers, not just the role of reservoir water for the residents, but also for residents of hydroelectric power. The researchers can take advantage of proposed reservoir of resources for building solar power plants in the reservoir, the solar electric power plants and hydro power plants and transmission networks, can take full advantage of existing resources and reduce transmission costs, providing people with more adequate energy.

Easy cleaning and cooling

　　The researchers used water solar concentrator systems to reduce the use of solar cells, and stable power generation . Compared with the conventional solar power, solar power water has its own outstanding advantages. First, the water can be directly used solar power to cool the water below, cooling costs low. Solar panels are often encountered overheating problems, so need cooling water for cooling. Second, can use water to clean solar panels. Dust, solar panels will become dirty, affecting the efficiency of solar power, so the need for regular cleaning solar panels. Solar panels to the ground, the cleaning cost a lot of money.

　　Water designed a modular solar power plants can be made ​​according to the required capacity to install solar panels, each module can produce 200 kilowatts of electricity. If you need to produce more power, just laying more modules. There was also a lot of bodies of water solar power, but most of the construction of floating platforms in the water, then lay on the platform of solar panels or solar panels directly to the bracket built in shallow waters. This method of light and ventilation are poor, on the waters of the plants and animals in the great waters, even over a period of time may become smelly “dead water.”

　　The French and Israeli researchers have developed solar panels water can float on water. The solar panel is very strong, can resist the impact of natural disasters. If the reservoir covered with such panels, and even pedestrians can be a floating bridge can be had. Water solar panels using a “breathable” the structure, to minimize the impact on the environment. Oxygen and some light can be through solar panels, so the water plants and animals to survive, will not be greatly affected. Dr. Kassel participated in the study, said: “Preliminary experiments showed that the solar power system will not affect water quality, aquatic animals and plants will not affect the normal growth and development process. Long-term impact is uncertain, but also environmental experts to do further evaluation. ”

　　Currently, researchers are creating the prototype solar system water, and in September this year, a reservoir in southeastern France to generate electricity in the experiment. In addition, researchers in Israel and India is a power company , in consultation experiment in India to build a power station . The researchers predicted that if all goes well, to June 2012 to complete all the experiments, the new solar power technology will enter the market after that.

Know more about investing solar power in India

Large solar players such as First Solar and Suntech Power have both recently emphasized increasing sales in India. Part of the reason for the potential growth in India is that the country published a policy called National Solar Mission in January 2010 that calls for adding 20 GW of grid-tied solar energy generation capacity and 2 GW of off-grid projects by 2022. In addition, the Indian state of Gujarat also has its own solar incentive program.

Lack of access to electricity for a large population of the poor in the country – as well as its growing greenhouse gas emissions – has made India an attractive target for solar companies. About 404 million people in India lack access to electricity, according to the International Energy Agency.

Nearly 69 percent of the country’s electricity production came from coal-fired power plants, according to the most recent, 2008 data posted by the IEA website. At 20 gigawatt-hours, solar electricity hardly makes a dent in the overall electricity generation of 830,126 gigawatt-hours. Investor Vinod Khosla has long said that clean tech solutions needs to meet the “Chindia” test, and be able to make a dent in energy markets of India and China.

The country’s renewable energy secretary on Thursday told reporters that the country plans to add 17 GW of renewable power generation capacity between 2012 and 2017, and that will need as much as 1.5 trillion rupees ($33.5 billion USD) to achieve. Most of that investment will have to come from the private sector though.
