Trabant partners with Siemens to develop game changing solar tracker
Sade's idea was to eliminate the need for masts or poles to secure a solar array to concrete foundations. Instead, the tracker would use a ballast pan filled with dirt, gravel or sand.
Small Companies Can Make a Big Difference in Tomorrow
During the conversation, I kept coming back to ‘Why? What was driving this desirable business behavior?' Larry summed it up. "At the end of the day - we work to do as much right as we can for all concerns. By being long-term, we can look at the long-term win-wins for both conserving our resources and with a competitive long-term cost benefit as well.
Scientists report first solar cell producing more electrons in photocurrent than solar photons entering cell
The external quantum efficiency for photocurrent, usually expressed as a percentage, is the number of electrons flowing per second in the external circuit of a solar cell divided by the number of photons per second of a specific energy (or wavelength) that enter the solar cell. None of the solar cells to date exhibit external photocurrent quantum efficiencies above 100 percent at any wavelength in the solar spectrum. The external quantum efficiency reached a peak value of 114 percent. The newly reported work marks a promising step toward developing Next Generation Solar Cells for both solar electricity and solar fuels that will be competitive with, or perhaps less costly than, energy from fossil or nuclear fuels.
A paper on the breakthrough appears in the Dec. 16 issue of Science Magazine. Titled "Peak External Photocurrent Quantum Efficiency Exceeding 100 percent via MEG in a Quantum Dot Solar Cell," it is co-authored by NREL scientists Octavi E. Semonin, Joseph M. Luther, Sukgeun Choi, Hsiang-Yu Chen, Jianbo Gao, Arthur J. Nozikand Matthew C. Beard. The research was supported by the Center for Advanced Solar Photophysics, an Energy Frontier Research Center funded by the DOE Office of Science, Office of Basic Energy Sciences. Semonin and Nozik are also affiliated with the University of Colorado at Boulder.
TÜV SÜD mapped the wind resource potential in the German federal state of Hesse
On behalf of the State Ministry of the Environment of Hesse, TÜV SÜD developed a wind map for the German federal state of Hesse. The wind map offers a high level of accuracy which makes it an important tool for identifying wind priority areas.
PVP HE String inverters
We believe that system owners and installers should take an active role in understanding how their system is performing and that basic web based monitoring should be free and flexible. Adhering to this philosophy, we have designed the ZigBee based monitoring solution for the PV Powered HE string inverter to make string inverter performance monitoring fast, easy, simple, reliable and flexible.

Buffett's MidAmerican makes second foray in solar
Warren Buffett's MidAmerican Energy Holdings made its second foray into solar energy in as many weeks, saying on Friday it will buy a 49 percent stake in an Arizona power plant from NRG Energy Inc (NRG.N). MidAmerican, the utility affiliate of Buffett's holding company Berkshire Hathaway Inc (BRKa.N), said it will take a stake in the 290-megawatt Agua Caliente project in Yuma County, Arizona. The plant is being built by solar power company First Solar Inc (FSLR.O) and is supported by a $967 million loan guarantee from the U.S. Department of Energy. The announcement comes a little over a week after MidAmerican said it would buy First Solar's 550 MW Topaz Solar Farm power plant in California.
