Solar power slate tile are made of monocrystalline silicon solar cells which are embedded in slate roof tile. By installation of overlapping, AnRoof solar slate tiles promise zero potential harm and zero dislodge risk. It's suggested to install on unshaded and sloping roof area. Excellent conversion rate make full use of house roof to provide seamless electricity in decades. It can be integrated to either on-grid or off-grid systems. The off-grid system is a stand-alone solar roofing system, ideal for home and business building that can't connect to country grid, the stable converted solar power can meet the needs of daily house electricity request. On-grid module enable house owners to sell extra solar power to grid companies besides daily electricity usage. The application area include residential, commercial and industrial buildings.

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.

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. source: http://www.solardaily.com/reports/Analysts_Predict_PV_Installations_To_Double_In_2011_999.html

Global solar PV power has achieved great success from 2007. According to annual growth of last 4 years, it's estimated that, in 2011 19.3 gigawatts (GW) is possible. From the '2007 WORLD PV INDUSTRY REPORT' , world solar photovoltaic (PV) market installations reached a record high of 2,826 megawatts (MW), representing growth of 62% over 2006. In 2008, a new record high of 5.95 gigawatts (GW), representing growth of 110% over the previous year. 7.3 gigawatt (GW) in 2009, representing growth of 20% over 2008. The reason for 2009 slowdown growth is attributed to Financial Crisis , even though solar PV is the world’s fastest growing energy source. The rapid growth observed by the global Solar PV market has been affected by the financial crisis. The impact of the financial crisis will be witnessed in the year 2009 with the dip in the annual solar PV installations in most of the countries engaged in the Solar PV electricity generation. By November 2010, a forecast from iSuppli po

A rich businessman was away enjoying his holiday in the Bahamas, when one evening he received a call from home. It was his butler. “Sir, I am very sorry to call you at this time,” he said, “but I figured that you should be informed right away. You see, your beloved cat somehow got onto the roof and fell. I am afraid the animal is dead now.” Expecting grief at this news, the butler was startled at his employer’s response: “Hey! Hey! Don’t they teach you anything in butler school?” Before his servant could reply the man went on: “You don’t just spring stuff like that on people. You always give bad news by degrees. What you should have done is send me a series of telegrams. The first one says, ‘Your cat is on the roof.’ Then the next one: ‘Cat fallen off roof.’ Then another one: ‘Cat in critical condition; prognosis poor.’ Then, when I’m prepared, you understand, I get: ‘Cat deceased.’ See? That’s how you give someone bad news.” The butler, of course, could only apologize profusely and as

On February 16-18 2011, the international roofing EXPO will be held in North Halls Las Vegas, Nevada USA. According to the official site , it will be the biggest expo in roofing history. Joe Theismann, NFL Network and Former Washington Redskins Star Quarterback, will present the Keynote Address on first day. The new Renewable Energy Pavilion which exhibits green/Eco-friendly, solar, photovoltaic, vegetative, roof-mounted wind turbines, day lighting, geothermal and other renewable energy products. It's said that the pavilion is free of charge for all registered attendees and open daily throughout the Expo. The Expo will last three days, followed by NRCA, NRLRC, ROOFPAC events.

In 2010, the most impressive innovation in roof tile development probably is solTech, which will convert solar energy to 'passive' heat. Its working theory is simple. Air below the glass tile is heated by the sun and redirected for use by the central heating system. The system works with air-based and water-based heating systems, including, for example, a ground source heat pump, air heat pump, pellet boiler, oil boiler, or electric boiler. The SolTech solar energy system , solTech System, is the flexible solar heating system that works for all types of buildings such as offices, hotels, appartment buildings and industrial buildings. The system is designed to be integrated with the existing house's energy solution, whether it is a ground source heat pump, air heat pump, pellet boiler, oil boiler or electric boiler. solTech roof system is especially helpful in snowy climates since snow easily slides down the glassy tiles. It's an idea to improve people's living condi
