Solar CEOs have a lot to say at tradeshow roundtable
Solar CEOs have a lot to say at tradeshow roundtable At the recent Solar Power International trade show and conference in California, several company executives and one state commissioner gathered to discuss the state of the solar industry. Marc Gunther from Fortune magazine led the discussion through topics of policy, what would be needed to drive the industry forward, the ambitious SEIA and SEPA goal to add 10 GW of solar power to the U.S. by 2015, and other issues affecting...

Solar Power, meet Plastic
Could plastic herald a revolution in the solar power market? Cheaper and lighter compared to silicon, plastic photovoltaics (PV) could just be the answer.“Plastics are much cheaper to process than silicon. In principle the devices we’ve been making might be very, very cheap and cover large areas,” said David Lidzey from the UK’s University of Sheffield. PV is far more flexible, allowing for easier installation. “If you’ve got panels that almost roll... Read More
Comprehensive test techniques for grid-tied solar inverters
Eric Turner, Product Marketing Manager, AMETEK Programmable Power, Renewable Energy Initiatives, San Diego, Calif. The ever-increasing deployment of residential and commercial photovoltaic arrays has created a high demand for small solar inverters, but they must be performance-tested to ensure they are ready for the long haul. The AMETEK MX is an example of a bi-directional power source that simulates the interconnection of the inverter to the grid under a range of operating... Read More
University of Minnesota Researchers Clear Major Hurdle in Road to High-efficiency Solar Cells
MINNEAPOLIS/ST. PAUL, MN — A team of University of Minnesota-led researchers has cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels, which rarely exceed 30 percent.By showing how energy that is now being lost from semiconductors in solar cells can be captured and transferred to electric circuits, the team has opened a new avenue for solar cell researchers seeking to build cheaper, more efficient...

Solar Alternatives for Energy Generation
By John R. Gyorki, Editorial Director Theoretical scientists have discovered many techniques for converting sunlight into electric energy, but only photovoltaic (PV) and concentrating solar power (CSP) systems show the most promise for practical applications.It’s always fun and interesting for engineers to focus on the technical development of emerging technologies such as solar energy and specifically, photovoltaics. But we often tend to forget the influence of... Read More
