North America doubled solar photovoltaic in 2011

Evolution Solar cheered a new report this week that claims that the number of solar photovoltaic installations in North America is likely to double in 2011.

Following a strong 2010 that will see around 1 GW of installations in North America, 2011 should bring over 2 GW of new installations across the continent.

If Holman and IDC's projections for 2011 are proven accurate, the new year will be a continuation of an exponential boom in PV installation in recent years. The gigawatt or so of capacity installed in 2010 more than doubled the 441 megawatts added in 2009.

GT Solar Receives $47.3 Million Order SDR400 CVD Reactors

GT Solar International, Inc . (NASDAQ: SOLR), a global provider of polysilicon production technology, and sapphire and silicon crystalline growth systems and materials for the solar, LED and other specialty markets, today announced that it has received a $47.3 million order from South Korea-based polysilicon producer OCI Company, Ltd. for its newest SDR™400 CVD reactors. This is OCI’s third order for GT Solar’s SDR400 CVD reactors. The new systems will be installed as the first phase of OCI’s new polysilicon capacity expansion plan, which OCI announced on December 8, 2010. The order will be included in GT Solar’s backlog for its current Q3 FY11, which ends on January 1, 2011. GT Solar SDRTM CVD Reactor Series are high volume production chambers that utilize the proven Siemens-type process technology to manufacture high quality semiconductor grade or solar grade polysilicon.

Solar Car Project?

Even though I put all of my attention on solar roof project around the world, a solar car project leaded by Stanford students distract me. Apparently, they are doing it good. A 1985 Matsuura CNC 3-axis mill, that's the raw material they are working on. Look at the picture on their blog , the mill was fully equiped with solar panels. I don't know the conversion rate of silicon cells they are using, but I think I can provide them some if they need. However, what they want to prove is simple that a solar power car can be made and drive. Great job, Stanford students!

MIT Students Let Roof Tile Changing Color Upon Temperature

After my last report on the MIT's innovation Solar bottle bulbs , here comes a new technology on roof tile - Thermeleon roof tile . A team of graduate students at the Massachusetts Institute of Technology think they might have an answer, a roof tile which turns white when it's hot and black when it's cold. According to report, the Thermeleon tiles use commercial polymers and solvents encapsulated between a clear plastic top layer and a black backing layer. When temperature is going down to a point, the polymer remains dissolved in the solvent, letting the black backing show through. When the tile gets hot, the polymer condenses into a white, heat-reflecting surface. Obviously, Thermeleon tile is good at controling housing temperature. It works like a cooling system in Summer, and a heater in Winter. However, how much it can help family cut electricity bill is still a question. It's a great idea, isn't it? The MIT students are pushing construction industry t...
