In a paper recently published in the journal Renewable Energy, “Optimum fixed orientations and benefits of tracking for capturing solar radiation in the continental United States,” Kleissl and his Ph.D. student Matt Lave explain why it’s important to strategize on solar installation, depending upon the location of the building relative to the sun.
The generally clear conditions during the annual load peaks (also known as Santa Anas to Southern Californians) mean that the solar panels produce at the optimum power. On the other hand, wholesale energy prices during the peak time may be 10 times those during other days. In a future with more variable electricity rates this margin may tip the balance of economics in favor of solar energy and there will be greater incentives for installing panels facing southwest. Our maps show that there are already benefits of doing so now as the energy generation increases.”
Kleissl further explains his intensive solar research at UC San Diego in this recent video produced by SPIE, the international society for optics and photonics.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
