ULVAC Inc recently announced that it has created and launched a very innovative battery-charging system for power-assisted bicycles by putting together a solar generator, a small wind power generator and a battery charger.
Currently, the U.S. Army’s electricity generators are largely dependent on oil. This is the reason why Uncle Sam plans to install solar powered microgrids in Afghanistan in order to reduce its energy-related vulnerabilities in the field.
A new solar cell efficiency record has been achieved by a startup CA-based company called Alta Devices. Previously unknown, the Santa Clara firm brags an efficiency of 28.2 percent for their gallium-arsenide solar cell, a number 2 percent higher than last year’s previous record, and could eventually bring down the costs of solar power to make it compete with coal and gas.
The UK has officially opened their largest solar energy farm at the Howberry business park in Oxfordshire. Being the first large ground system connected to the national grid, this solar park is capable of generating about 683 MWh of solar energy annually.
A solar cell developed at the Unversity of Toronto, Canada, is able to harvest both visible and infrared light and can theoretically achieve efficiencies of up to 42 percent. Their tandem solar cell is based on colloidal quantum dots (CQD), and the team has been led by Professor Ted Sargent, a Professor of Electrical and Computer Engineering.
Since 2009, Prologis, a leading global provider of industrial real estate, has been installing solar photovoltaic cells on the roofs of their own properties. Now they come up with a project, named Project Amp, that aims to install solar panels on the rooftops of 750 buildings across the US to produce 733MW of clean power.
I’ve been writing about Nokia testing a solar powered version of one of their cellphones just the other day, and thought it’s a pretty stupid idea to apply solar cells on phones since they’re kept mostly inside pockets, and they aren’t transparent. Today I found out that a company called Voltaic is releasing a solar powered carrying case for tablets – the Spark.
Tata Steel, India’s leading supplier of stainless steel, in partnership with the Australian solar technology company Dyesol, has recently developed the world’s largest girder coated with solar panels.
Nokia is seemingly testing a solar powered phone these days in different conditions from different parts of the globe. They put four of their C1-02 devices, each having an attached solar panel and sent them to Kenya, the Arctic Circle, Sweden and to a boat on the Baltic Sea.
Sempra Energy is the company that won a $359 million conditional loan guarantee last week from the Department of Energy regarding the construction of a 700MW solar power plant in the Mesquite desert in Arizona.
I didn’t know the Guiness Book awards solar cell efficiencies lately. This story I read on Cleantechnica tells how SunPower, “the most popular solar panels company in California,” got into the Guinness Book for providing people with “the most efficient commercially available photovoltaic modules on the market.”
Special planes equipped with a special laser system called Lidar flew over New York last year and scanned all the potential rooftops out of more than one million on which solar panels could be installed to properly produce power, NYTimes reports.
According to a recent report made by tue World Bank, over one million homes from Bangladesh are powered by solar energy, being the fastest expansion of solar use in the world.
SolarCity, the company founded by Elon Musk (who also created Tesla Motors, Paypal) has just received $280 million from Google. The investment is one of the largest in solar power worldwide, and aims to help 7,000 to 9,000 homeowners in the 10 states where SolarCity operates install solar panels onto their rooftops.
A new device that harvests energy from raindrops, winds or sunlight has been invented at the Institute for Materials Research and Innovation at the University of Bolton, UK. Elias Siores led a team who created a special polymer with piezoelectric and photosensitive properties.
