MIT Energy Initiative: With changes, U.S. electric grid can hold up to expected challenges
MIT report shows that with new policies, U.S. electric grid could handle expected influx of electric cars and wind and solar generation.
Solar Infrastructure Codes
Unirac is a strong advocate for developing new codes for solar infrastructure, and has been working closely with the International Code Council Evaluation Service to develop new performance standards for racking and mounting systems. Unirac's new SolarMount (E)volution residential roof mount PV racking system, launched at Solar Power International in October, is currently being evaluated by ICC-ES. Unirac is the first company to apply for an ICC ESR under ICC-ES AC428.
Striking Balance - How the Solar Industry Benefits From the U.S. & China
The solar industry is ready for its moment in the sun: Here at home, we hope fairness prevails so that the investigatory process proceeds without acrimony, political overzealousness or protectionism; at stake are U.S. jobs, U.S. exports, and U.S. consumer benefits for a strategically important U.S industry
Solar Technology Comparison Study
Wastewater Engineering Building - LEED Gold Certified
Both thin film and crystalline solar technologies provide reliable and impressive energy production performance. While it is well known that amorphous silicon modules suffer lower performance loss in high temperatures and low light conditions, this study reveals that the differing mounting requirements of each system more than offset this cell-type difference. As a result, with commonly-used commercial mounting solutions, crystalline modules actually outperform thin film modules in energy production per rated watt.
Solar Cogeneration Technology
Solar cogeneration of electricity and hot water maximizes the economic and environmental value of energy derived from the sun. Cogenra's system produces as much electricity as photovoltaic (PV) technology allows, then captures most of the remaining energy as hot water, in total exploiting over 70% of the energy incident from the sun.
India Embraces Solar Power, Says Price Will Equal Thermal Power in Five Years
The program's goals are nothing if not ambitious, as the government had initially hoped to boost the nation's solar capacity by the equivalent of about 18 nuclear power plants by 2022, a date that's now been brought forward by five years.
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.
