Arizona State University's (ASU) polytechnic campus in Mesa, Arizona, has become home to a 1MW PV system engineered and constructed by PV developer SunPower.

The system represents the first commercial deployment of SunPower’s C7 Tracker technology, a tracking system which, the company claims, concentrates the sun's power seven times to achieve one of the lowest levelized costs of electricity (LCOE) for solar power plants available today.

The C7 Tracker combines single-axis tracking technology with rows of parabolic mirrors which reflect light onto SunPower Maxeon solar cells. These cells have an efficiency of 22.8%.

In addition to building the system, SunPower is also operating and maintaining the facility which is expected to generate enough power to meet the demands of around 225 homes.

Un concentrateur solaire érigé au parc Innovation
Publié le 26 mars 2013 à 08h59 | Mis à jour le 26 mars 2013 à 08h59

(Sherbrooke) Un projet unique au Canada voit le jour dans le parc Innovation de l'UdeS. Au cours des prochaines semaines, un concentrateur solaire sera érigé au sud de l'Institut interdisciplinaire d'innovation technologique 3IT. L'infrastructure d'environ huit mètres, qui pourra produire de l'électricité, permettra de mener un projet de recherche sur l'énergie solaire, plus spécifiquement en photovoltaïque.

«Des sites comme ceux-là, il n'y en a pas beaucoup sur la planète», lance Vincent Aimez, professeur à la faculté de génie de l'Université de Sherbrooke et directeur du développement de partenariats scientifiques dans le domaine des nanotechnologies.

Les travaux viennent tout juste de commencer à proximité du 3IT.

Le démonstrateur sera équipé de miroirs (une surface d'environ 100 mètres carrés), qui serviront à renvoyer la lumière du soleil sur les cellules photovoltaïques. L'équipement, doté de moteurs, pourra suivre le soleil au fil de la journée. Avec l'outil de recherche grandeur nature, le soleil sera concentré mille fois à l'endroit où il arrive sur les cellules.

Mexico's Thatched-Roof CocoCabañas Resort is Powered Entirely by Solar Energy
by Lori Zimmer, 04/05/13

Tucked away on the Isla de Navidad peninsula on Mexico’s Central Pacific coast is the beautifully rustic, solar-powered CocoCabañas Resort. The native bamboo Cabaña guest rooms are just a stone’s throw from the pristine Coconut Beach. Best of all, the entire resort is powered by a massive solar array, which provides lighting, hot water, and power for ceiling fans in the naturally cool escape.



The resort’s sophisticated photovoltaic system is made up of 2400 W Isofoton solar panels, 24 Trojan L-16 batteries and 2 SMA Sunny Island 4200 W inverters for AC power. The complex system provides enough power for all lights, ceiling fans, refrigerators, well pumps, swimming pool pump, entertainment systems, computers, communications equipment, washer/dryers and power outlets. There is also a 12 kW Onan propane generator on site for emergency backup energy.

CocoCabañas is the ultimate eco-escape, giving guests an isolated beach experience far from the reaches of their normal lives.
