Busting the problem of cloud cover

The downside to solar power is that it's not always sunny and so grid operators have to compensate for energy drops by bringing alternative generation sources online. New research in the International Journal of Powertrains, ...

Solar energy solutions for facades

Photovoltaic elements are usually found on rooftops—after all, that's where solar irradiation is highest. However, as researchers at the Fraunhofer Center for Silicon Photovoltaics CSP have discovered, PV elements on facades ...

Irradiation

Irradiation is the process by which an object is exposed to radiation. The exposure can originate from various sources, including natural sources. Most frequently the term refers to ionizing radiation, and to a level of radiation that will serve a specific purpose, rather than radiation exposure to normal levels of background radiation. The term irradiation usually excludes the exposure to non-ionizing radiation, such as microwaves from cellular phones or electromagnetic waves emitted by radio and TV receivers and power supplies.
