Researchers Double Efficiency of See-Through Cells

        Researchers at UCLA have developed a new type of see-through solar cell that could be used applicably on windows, car sunroofs, smartphone screens and other transparent surfaces that can harvest energy from the sun. First developed in the year 2012, the researchers currently have almost doubled the efficiency of the solar cell, approaching the subject of commercial visibility very closely.
        The solar device is compromised of two thin polymer solar cells that can be made in shades from light green and gray to brown, which helps to camouflage them within the colors of surfaces on buildings and other structures. The solar cells absorb more light, harvest light and use the energy from a wider point-of-view, and incorporates a variety of materials between the two solar cells to reduce energy loss. The technology had previously had an efficiency level of only 4% but the UCLA team has brought the efficiency level to 7.3%.

How the Tesla Motors S is Made

      Tesla Motors, the company responsible for mass producing the electric car Model S, has claimed to be confident that the production would double to 800 per week until late 2014. In other words, they believe themselves to making equivalent to 40,000 Model S vehicles per year. The latest news provided with an interview with Co-Founder Elon Musk notes that he has said that right now they are "above 400 a week at the current manpower, and not trivially above it." Thus, this helps form the conclusion that they hold of the number they would be mass producing and selling.

       But, how is Tesla Motors S able to produce such a large number of vehicles in a short length of time? How are they different from other automakers when it comes to building the cars? What helps them be more efficient?

Solar Day Pilipinas -- A Yearly Event From Now On

      During this extreme heatwave coming this summer in the Philippines, there lies potential for solar power to grow as our reliance on fossil fuels can be reduced or dimmed. The Philippine Solar Power Alliance (PSPA) and the World Wide Fund for Nature Philippines (WWF) has, in fact, celebrated their very first Solar Day Pilipinas 2013 on April 26. PSPA President Dante Briones had described solar power as being a cutting-edge technology and a tool for improving national competitiveness, especially in the Philippines. "The country is actually one of the leading countries in Asia when it comes to solar energy," Briones said.
      Solar power is also estimated to produce 20-30% less emissions of harmful gases than coal power. "Why do we have to thoroughly dig the soil just to look for coal when all we need is to raise our heads to see the sun?" said Claire Marie Yvonne Lee, PSPA Vice President. According to Lee, she observed that many businesses and institutions have already begun to start using solar panels. Some of these, she points out, are Starbucks, the Asian Development Bank, the Makati Medical Center and the Department of Trade and Industry.
       Solar power, however, proves to be quite costly. As a matter of fact, the cost of acquiring one solar panel may exceed the initial savings generated from not connecting to the country's power grid. Though this may be so, PSPA and WWF believe that as costs decrease, solar panels will be economically efficient over time. In addition, solar technology usually is covered by a 25-year warranty. "A solar system is a good investment," said Lee. "Unlike a car or a cellphone, it's not a dead investment," she added.
       At Solar Day Pilipinas 2013, there were products of various solar power developers showcased for the public to view. The products consisted of a range of solar phone chargers to large-scale solar systems for residential areas and commercial establishments. Ten solar power developers present were included as follows: Renewables Made in Germany, MERALCO, Tritec, Transnational Uyeno Solar Corporation, GNB Exite, Maschinen and Technik Inc., Cagayan Electric Power, Sasonbisolar Inc., One Renewable Energy Enterprise Inc., Solutions Using Renewable Energy Inc., CEnAG, SunPower Inc., and Propmech. "Solar Day Pilipinas will be a yearly event from now on," said PSPA Founder and Chair Teresa Cruz-Capellan.

Free Solar Panels for Honda customers?

       Tesla Motors has been getting ahead in the electric vehicle market because of their newly produced car, Model S. Many car manufacturers are concerned with the shift in the market; this actually includes Honda Motor Company Ltd, the Japanese car manufacturing company to be established in 1948. Honda has recently decided to have a partnership with Solarcity, an American provider of energy services, to offer cheap solar power to eligible customers. They promised that with this incentive, they will be guaranteeing a utility bill for solar power producing a lower rate than grid-supplied energy. This not only includes cheap solar energy but, it also means the eligible Honda and Acura customers would be obtaining a rooftop solar panel installation, covering all the costs including the cost of the panels itself.
       The agreement that has been established between Honda and Solarcity is a power purchase agreement, which is a popular tactic to finance solar installations. Power purchase agreements are designed as contracts between two parties, whereas typically the property owner pays for electricity at a reasonable price rate for a period of time but the installer has continual access to own, operate, and maintain the system for that time period. It's not unusual for this partnership to also offer insurance, maintenance, repair and monitoring during the specified time period.
       Honda customers are able to pay for their bills up front in two ways: either pre-pay for the solar electricity or pay at a monthly rate which is lower rate than their utility bill. Surprisingly, Honda and Solarcity had invested $65 million into a fund for this agreement, which covers dealerships and customers located within Solarcity's few state service areas. This includes other efficiency upgrades for customers such as weatherization, a practice of protecting establishments and its interior from all weather (sunlight, precipitation, wind) and modifying it to reduce energy consumption and optimize energy efficiency.
     Not a bad deal if they're planning to be ahead of the other car manufacturers to be on a head-on competition with Tesla Motors, right? What do you think?

5 Green Tech Trends in 2013

1. Solar Power Technology
The solar industry is facing a decline in price by 2016 when federal investment tax credit for solar installations from 30% to 10%. Though 4 years may seem a lengthy time, it is the same amount of time for a large solar power plant to be permitted, financed and constructed. Thus, as this new year kicks off, be sure to be on a lookout for there will be new discoveries to finance solar power installations, whether it will be residential installed solar panels or solar power plants in remote areas. An example of this could possibly be solar securitization, whereas the leases for residential solar power installations are bundled and sold to investors. Another example is known as crowdsourcing, where investors help finance projects and they would be shareholders of the company by buying a piece of the pie.

2. Watch Out For Solar Energy in California
BrightSource Energy's 370-megawatt Ivanpah "power tower" plant is going online in 2013 and it's the first big solar thermal facility in the U.S. that has been planned to be built more than 20 years. Solar thermal power plant uses mirrors to focus on the sun while it is on top of a liquid-filled boiler to generate more electricity. Though this may be exciting to experiment with, many developers tend to stick with the traditional, inexpensive way of producing solar panels; however, if this power plant is to produce interesting results, it may change these perspectives of solar panels.

3. Tesla Motors is getting ahead in the competition
With the production of the Model S, which is a high-performance electric sports sedan, Tesla Motors is getting ahead of the game in terms of the electric car market because of Silicon Valley company's network of Superchargers. For anyone who have no prior knowledge of this Supercharger network, it is a network of solar-powered chargers that will refill your Tesla Motors Model S free of charge. Not only that but the Model S charges 4-5x the rate of a high-capacity home charger, meaning you can get as far as 150 miles in half an hour. Great car, Tesla; props to you.

4. Biofuels are Advancing
Not only is solar technology advancing but there is a struggling revival of biofuels in place. The Sapphire Energy's algae biofuel demonstration plant in New Mexico desert is producing green crude, which is renewable crude oil made from sunlight, carbon dioxide, and algae to make green oils that can be converted into fuel. SG Biofuels of San Diego are also breeding new branches of jatropha, which is an inedible plant in South America and Africa, to help boost oil yields. 

Sapphire Energy is producing a 100-acre algae field in Southern New Mexico. 

5. China is, of course, winning in this battle of Solar Energy
While many U.S. startups on solar energy are declining, Chinese solar powered manufacturers are supported intensely by their government in that they receive enormous subsidies. In a recent news article, it is discovered that the Chinese is expanding more faster than expected - a Chinese firm had bought an American solar startup. MiaSolé has been expected to stand firm in this competition but in Beijing, it has been announced that Hanergy Holding Group of China, specialized in building hydroelectric dams, completed the purchase of the company and its technology for a fraction of what the investors had put in.
