Concentrator Photovoltaics: The Next Step Towards Better Solar Power

By Lauren J. Young for IEEE Spectrum:  Today’s concentrator photovoltaic (CPV) technologies have shown promising potential for more efficient solar power. The latest systems are said to be capable of handling the power of a hundred suns. Yet prototypes have failed to compete with cheaper flat panel solar systems that dominate the market. The U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E) is determined to push CPV to the next level. On 24 August, at the Clean Energy Summit, U.S. President Barack Obama and Energy Secretary Ernest Monizannounced a program called MOSAIC that will invest $24 million into CPV solar technology development.

Why can’t today’s CPV systems compete? The concentrators can only convert direct sunlight into energy, missing out on the large fraction of sunlight diffracted by clouds and the atmosphere. Manufacturing costs of concentrator apparatuses have also prevented CPV from reaching mass production.  Cont'd...

WS510 Secondary Standard

WS510 Secondary Standard

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.
