China Wins Deal of One of World's Largest Solar Power Plant in the U.S.

        Trina Solar Unlimited, one of the world's leading PV companies founded in 1997, had announced today that it will supply 1.1 million photovoltaic panels for a 250-megawatt power plant to be built in the Nevada Desert. It will not only be one of the world's largest photovoltaic power stations but it will also be the largest in the U.S. to use Chinese-made solar panels.
        While Chinese companies have attained control of most of the U.S. residential market, utilities and developers of solar power plants have actually favored U.S. companies such as First Solar and SunPower. However, this favoritism is drastically changing. In November, another Chinese solar manufacturer Yingli, won a contract to provide panels for a 200-megawatt power plant under construction in the California desert outside of San Diego.
         As the Chinese market is advancing, Trina Solar and Yingli are emerging as China's top competitors in the power plant industry. Thus, Trina and Yingli have taken measures to ensure distance from other Chinese manufacturers, whom are faced extreme pressure to cut costs as they struggle with billions of dollars in debt, and emphasize the quality of their products.

Sharp Develops See-Through Solar Panels

         Sharp Electronics, a United States subsidiary of an Osaka-based Sharp Corporation and a company known for manufacturing a wide range of consumer and business products, has announced the development of see-through solar panels that offers many benefits over the standard solar panel. The semi-transparent solar panel is designed to be used in balcony railings or as windows in tall buildings, where it can generate energy while also letting light in. The glass, while see-through up close, creates a privacy screen from farther away, acts as a heat shield and is aesthetically pleasing to the eye as well.
        According to CNET, the solar panel "delivers a solar power conversion efficiency of about 6.8-percent with a maximum output of 95 watts." This is quite a bit lower than standard solar panels that typically may have conversion efficiencies of 15 to 20 percent, but then again, standard solar panels can't act as windows.
       Even with a lower efficiency level, the see-through solar panels are generating energy in parts of a building that would typically consist of ordinary glass or metal, so they're still increasing the potential renewable energy generation of a building by a significant amount.
      The panels are also constructed with laminated glass that has been infused with photovoltaic solar cells and are 4.5-feet wide by 3.2-feet tall and only 0.3 inches thick. They will go on sale in Japan on October 1, but so far, no pricing or plans for a release in the United States has been revealed as of yet.

Solar Impulse: Last Trip from Washington, D.C., to New York

            The ultimate goal for Solar Impulse was to fly across the globe powered solely upon the sun's rays. So far, it has accomplished many goals in the last three years: in 2010, it flew for 26 hours straight; in 2011, it flew from Belgium to Paris, France and in 2012, a prototype had completed the first intercontinental flight connecting from Europe to Africa. This year, it proposed a challenge to fly across United States from the East coast to the West. 

The itinerary featured: from San Francisco (California) to Phoenix (Arizona) to Dallas (Texas) to St. Louis (Missouri) ending in the last haul to Washington, D.C., and New York

The fourth leg from St. Louis to Washington, D.C., has been completed successfully while the trip from Washington D.C., to New York is steadily approaching. You can view updates and the schedule for the rest of the historic flight here.

There are also many videos of their stops featured here.

Solar-Powered Plane's Cross-Country Flight

        Researchers at Moffett Air Field at NASA Ames Research Center in Mountain View, California, announced on March 28 that Solar Impulse, an ultra-lightweight plane solely powered by solar power, is planned to fly coast-to-coast this spring. The plane is claimed to require no fuel and solely rely on solar panels and battery power.
        Two Swiss pilots of the Solar Impulse, Bertrand Piccard and Andre Borschberg, desire to complete a flight beginning from Moffett Field to New York City. Along the way, it is planned to stop by in the following locations: Phoenix, Arizona, Dallas-Ft. Worth, Washington, D.C., and either Nashville, Tennessee, Atlanta, Georgia, or St. Louis. The plane is set to fly on May 1 and plans to land in the Big Apple in early July.
         Solar Impulse has a wingspan equivalent to a 747 jetliner, the weight of a station wagon, and the power needs of a small scooter. The solar panels across its wings harness power from the sun during the day, and lithium-polymer batteries store that energy for overnight trips. A carbon-fiber material formed in a honeycomb structure makes up the bulk of the plane, which allows for its feather-weight.
        In 2010, the plane completed a 26 overnight-hour flight and in 2012, it flew from Switzerland to Morocco with no fuel.

New Solar Gear Introduced

            Inverters are the components within powered devices like solar panels and batteries, which helps convert the power generated into usable power. There has been many research efforts involving solar panel inverters as some people may choose to move from a single large central inverter to smaller "microinverters" embedded on each solar panel. However, Empower Micro Systems, a chip startup that has been running for a year and a half now, has furthered this research and developed a low-voltage solar microinverter based on new chip designs, which has became more reliant, cost-effective, and efficient.

            Empower Micro Systems CCO Jon Bonanno has claimed that the company's inverter technology "is a quantum change in how solar is done." This newly developed chip component can be applied anywhere from a solar panel system to a rack or frame. Bonanno also notes that the inverter is 5x more reliable, 5% more efficient, and costs 20% less than traditionally used inverters. The overall solar system cost can be lowered because of the rising potential of a lower inverter cost, in addition to the dropping prices already of solar panels.
           Empower Micro Systems does not plan on manufacturing the inverter box itself but the company tries to respectfully adopt Intel's code in churning out the chips inside the inverter devices. Bonanno is confident of the power of the inverter technology, which is known as the "Universal Micro Power Inverter." He believes it can "replace all solar inversion options, hands down." The key technologies of the solar inverter includes how the system on a chip synchronizes and controls the power flow at a low-voltage rate as well as the design of the inverter box.
           Bonanno remarks that the company has already signed one agreement with a "top-three" module maker (and is in discussions with many module makers and product vendors) to bring this hardware into the market. This year, it is planned for the inverter to be certified and could be produced in pilot production by the third quarter of 2013.

Sports and Solar Power Energy

       The 2013 National Football Season may be six months away but one team is helping their community in sustaining a new outlook of their football stadium from a spectator sport to one who is involved with environment sustainability. Sunpower Corporation, a company involved in manufacturing solar panels, roof tiles, and high-efficiency photovoltaic cells, has been giving the opportunity to help the recent Superbowl Finalists, the San Francisco 49ers, by providing them with a solar panel system for their new stadium.

Santa Clara stadium, where the San Francisco 49ers will be playing their home games

       Sunpower Corporation has a partnership with NRG Energy, a large American-based company specializing in green-tech energy projects, and they are both collaborating on providing Santa Clara stadium with energy sustainability. NRG Energy is actually most known for its projects such as the electric vehicles' charging stations in California and wind farms in Texas; the company will be installing a number of solar elements on the stadium, giving it enough energy over the course of the year to offset the power consumed during the 49ers home games.
       This new system will be installed as three solar array bridges of solar panels of 400 kilowatts are done at the training center as well as there being a solar canopy built over a green roof terrace. The installation of the solar canopy defines it to be pro-football's first green rooftop, specifically as a 27,000 square foot canopy covered with vegetation, which will help insulate stadium's luxury suites as well as help to reduce stormwater runoff.

        However, this announcement of Sunpower Corporation and NRG Energy is not an unfamiliar one; it is part of the green trend spreading through NFL and other spectating sports. Metlife Stadium, home of the New York Giants and New York Jets, has 1,350 solar panels installed, producing 350,000 kilo-watt hours (or 10% of the stadium's energy on game day).

       The Fedex Field, home of the Washington Redskins, has also been involved in the green trend by having produced a total of 8,000 solar panels, providing them with 1/5 of their required energy needs.

       Major League Baseball participates in having stadiums of renewable energy sustainability in wind and solar power: San Francisco Giants, Milwaukee Brewers, Minnesota Twins, Washington Nationals, Cleveland Indians and Kansas City Royals.

South Korea envisions solar clad bridge in the future

The near future is coming; countries all over the world are finding ways to produce energy in an infinite amount like a endless cycle of energy that can never diminish. Natural gas will soon be the end of days while people will turn their shoulders towards a new approach, followed by large sums of investors, following a new market trend that will soon go towards wind, solar, and hydrogen powered technology that will change the world. Seems like South Korea is a step ahead, envisioning a solar powered bridge stretching across the famous Han River, powered by solar panels all over it, juicing up malls, museums, libraries, and other public recreational structures. Walking through the Brooklyn Bridge, in my opinion, felt amusing with the amazing view of New York but seeing this makes me think, America needs to catch up with their technology.
