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.
The South Africa Baviaanspoort site has yielded significant savings in terms of maintenance and repair costs and improved reliability over the duration that the ElectraGen™ ME has been installed.
The clean energy provided by the solar array will result in 1,810,000 fewer pounds of carbon dioxide being emitted annually, while reducing the University's energy costs by 30%.
Bard College and Hawthorne Ridge Retirement Community are two examples of down to earth solar energy projects that make a difference.
The idea of using hydrogen fuel cells instead of lead- acid batteries in the material handling equipment was introduced because of significant benefits offered by the alternative energy power source—increased sustainability, less maintenance requirements and operator self-sufficiency.
Many fuel cells are being used at locations that people would never expect. To follow up on our series of fuel cell road trip articles ( http://www.altenergymag.com/emagazine/2010/02/fuel-cell-road-trip/1450 ), we've found some up and coming fuel cell destinations that are worthy of a stop on your next summer vacation.

Even during Vermont's shortest days, the systems can collect enough energy to support their normal operation through 15 hour nights. This is partly due to algorithms built into the controller to monitor and adjust voltage from the solar module (Maximum Power Tracking).

Here are 5 of the entries in this years Solar Decathlon for your interest and enjoyment. More to come in future issues. These students have earned the support of us all. Thanks for giving us your view of the future!
The four larger panels pictured, consist of two systems. Upon a closer look, an observer will notice that visually the system is divided up in to two pairs of collectors that have a slightly different appearance from one another. Of the two pairs, one pair creates hot water for the facility and the other pair creates warm air for the structure.
Since the solar bike port's October 2010 installation, students have shown an increased awareness of solar power and energy production, and are enjoying learning how their school's green features help lower their environmental footprint. And the enthusiasm is expanding beyond the student body to embrace teachers, parents and professionals from other schools - both within and outside of Boulder Valley.
Our local manufacturing operations will allow Suntech to meet the growing demands of customers throughout the Americas, including our dealer network with more than 400 partners. One advantage is that all modules produced at the facility are compliant for procurement in American Recovery and Reinvestment Act (ARRA) projects. Also, in the long term, regional manufacturing will help to minimize our exposure to rising oil and transportation costs.

In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
