Shanghai Railway Station Benefits 6.8 MW Solar Power Plant Since Sunday

Posted by Ovidiu Sandru in Solar Power on July 20, 2010

Germany and Spain may be the leaders in solar photovoltaics, but China comes from behind and amazes everyone with an enormous power station just above the Beijing-Shanghai railway station. The plant is able to produce 6.3 MWh (megawatt-hours) of electricity and can provide the needs of 12,000 households in Shanghai.

EU Plans to Import Solar and Wind Generated Electricity from North Africa

Posted by Cristi in Solar Power, Wind Power on June 23, 2010

In order to reach the 2020 target of having at least 20% of energy produced from renewable sources, The European Union will invest in solar and wind energy in North Africa. The resulted clean power will be imported in the EU via a new electricity interconnector design. Electricity will be carried via these cables running under the Mediterranean Sea directly to Europe.

First Solar Signs Agreements With Major Energy Utilities to Provide Solar Power

Posted by Cristi in Green Economics, Solar Power on March 23, 2010

First Solar Inc. has recently announced that it will start working on a huge photovoltaic project called Desert Sunlight in Southern California. The facility will produce 550 MW from solar power, of which 300 MW will be sold to California’s Pacific Gas and Electric Company (PG&E) and 250 MW to Southern California Edison (SCE).

Google Improving Mirror Technology For Making Solar Concentrators 2x Cheaper

Posted by Ovidiu Sandru in Solar Power on March 2, 2010

Besides its search engine activities, Google focused on producing alternative energy technologies, or improving the existing ones. So is the case now, when Google developed a new mirror technology that could help solar companies like eSolar or BrightSource make cheaper and better solar thermal plants.

Fraunhofer's Very Efficient Solar Cell Concentrator

Posted by Cristi in Solar Power on June 27, 2009

Solar cell system which concentrate solar light through lenses seem to be the most efficient and advantageous. The concentrator enables the system to work with cheaper lens system instead of expensive semi-conductor materials, making it as well more efficient.

ElectraWall Photovoltaic System Working Even at Night Time

Posted by Cristi in Solar Power on June 1, 2009

Your safety is the thing that counts most while being behind the wheel on the highway. And when the night falls the situation is getting critical. But Solaroad Technologies Group has thought of a system that can light the roads using the daylight energy.

Solar Cooking "Kyoto Box" Reduces Pollution and Deforestation

Posted by Cristi in Solar Power on April 12, 2009

Jon Boehmer, a Norwegian based in Kenya, developed a solar powered cooker that can reduce greenhouse gases at a large scale. The cardbox named the “Kyoto Box”, costs 5 Euro($ 6,60) to make, and is designed for the usage of 3 billion people that use firewood as a heating source for cooking.

BOINC Software to Cut 20 Years in Solar Cell Development

Posted by Ovidiu Sandru in Solar Power on December 10, 2008

Everyone knows two are more powerful than one. On the same principle, IBM and Harvard University researchers launched a joint project today in an effort to search for the optimum combination of materials to create the most efficient solar cells ever.

New Electron Cooling Discovery to Extract More Energy from Solar Cells

Posted by Ovidiu Sandru in New Inventions, Solar Power on November 17, 2008

Do you know that electrons can be “cooled”? The cooling of an electron, in lay language, is the transitory state in which the electron passes from a high-oscillation state to a low-oscillation, normal state. The high oscillation state is given by an external stimulus, i.e. electric voltage.

Hydrogen to be Produced Cheaply With 19th Century Invention

Posted by Ovidiu Sandru in Hydrogen Power, Solar Power on November 16, 2008

G.D. Botto, an Italian inventor and physicist, performing experiments on a technique for hydrogen generation, has discovered that a chain of iron and platinum wires, wrapped around a wooden stick and alternately connected as thermocouples, can be used to convert a temperature difference into an electric voltage.

New Anti-Reflective Coating Make Solar Panels Absorb 96.2% Sunlight

Posted by Ovidiu Sandru in New Inventions, Solar Power on November 4, 2008

I like the way science evolves and still, for years, nobody seems to look at the new inventions. This may be the case with solar, because almost weekly we discover news about useful inventions in the area of solar power. Instead, old and inefficient methods are still being commercialized and “promoted”, at their high prices, like it’s wanted to decrease their real usage in real life conditions, not promote it.

Video: How a Solar Furnace Melts a Piece of Steel

Posted by Ovidiu Sandru in Solar Power on October 24, 2008

By writing the previous article and doing some research on steel and solar power, I came across a YouTube video showing what a solar furnace (or solar concentrator) can do to a piece of steel. While cooking a hot dog is “a child’s play”, melting steel is something you must seriously think about.

First Chinese Solar Powered Cars Unveiled

Posted by Ovidiu Sandru in Electric Vehicles, Solar Power on October 21, 2008

Unlike the Americans or the Europeans, the Chinese know their way into the cleaner future everybody dreams of. They probably began understanding a long time ago and now bringing into practice the cleanest possible way of transportation: a solar powered electric car.

Solyndra Cylindrical Solar Panels: Cheaper and Powerful

Posted by Mihai Sandru in Solar Power on October 13, 2008

Solyndra, a company situated in Fremont, CA, has invented a new type of cylindrical solar panel, cheaper to install and more powerful compared to the conventional panels, which are made of flat solar cells.

Highly Efficient Flexible Silicon Solar Cells Invented

Posted by Ovidiu Sandru in New Inventions, Solar Power on October 8, 2008

Scientists from the University of Illinois at Urbana-Champaign and Northwestern University invented a silicon solar cell. The interesting fact is that it’s flexible and it can be printed on a curved surface or a fabric. Although solar paint has been produced, there are a few situations where you’d rather use more solid solar cells (like porous surfaces, where paint cannot be applied well).
