A PhD student at the Environment and Sustainability Institute (ESI) on the University of Exeter’s Penryn Campus has published research whose aim is to help improve the efficiency and performance of Building Integrated Photovoltaic (BiPV) systems.

BiPV systems are increasingly important; their photovoltaic – PV – power is generated close to where it’s consumed, so it’s well integrated into the building’s architecture and, having no distance to travel, loses little power on the way. However, the technology can be expensive and less efficient than it might be, which is where Hasan Baig’s research can make a contribution. He’s experimenting with Building Integrated Concentrated Photovoltaic (BICPV) systems: these concentrate sunlight and could integrate well in the building architecture. (more…)

The Installed Price of Solar Photovoltaic Systems in the U.S. Continues to Decline at a Rapid Pace

Berkeley, CA — The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2011 and through the first half of 2012, according to the latest edition of Tracking the Sun, an annual PV cost-tracking report produced by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).

The median installed price of residential and commercial PV systems completed in 2011 fell by roughly 11 to 14 percent from the year before, depending on system size, and, in California, prices fell by an additional 3 to 7 percent within the first six months of 2012. These recent installed price reductions are attributable, in large part, to dramatic reductions in PV module prices, which have been falling precipitously since 2008. (more…)

Innovations by a team of Yale University researchers could lead to improvements in basic solar power technology that result in lower-cost, higher-efficiency photovoltaic systems.

Photovoltaics (PV) directly convert sunlight into electricity. PV systems can be arrayed on rooftops to generate electricity for entire buildings, among other uses. Less expensive, more efficient systems could encourage broader use of this clean energy technology. (more…)
