Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon commonly studied in physics, photochemistry and electrochemistry. A photovoltaic system employs solar panels composed of a number of solar cells to supply usable solar power. The process is both physical and chemical in nature, as the first step involves the photoelectric effect from which a second electrochemical process take place involving crystallized atoms being ionized in a series, generating an electric current. Power generation from solar PV has long been seen as a clean sustainable energy technology which draws upon the planet’s most plentiful and widely distributed renewable energy source – the sun.

Solar and Energy Storage Financing for Schools

Solar and Energy Storage Financing for Schools

Jason Coughlin, a solar analyst at the National Renewable Energy Laboratory, was coauthor of a 2011 report, “Solar Schools Assessment and Implementation Project: Financing Options for Solar Installations on K–12 Schools.”

“Schools have continued to install solar using power purchase agreements (PPAs) and the trend is to continue seeing third-party installations,” says Coughlin.

The Unmanned Power Plant—from Science Fiction to Industrial Reality

The Unmanned Power Plant—from Science Fiction to Industrial Reality

Author: Azeez Mohammed, president & CEO, GE’s Power Conversion

Driverless cars, artificial intelligence, even unmanned ships—in every corner of life it would seem that what was once science fiction is rapidly becoming reality. The same is true in solar power generation—while the idea of unmanned solar plants may appear fanciful,

The Physics of CHP Cogeneration and Heat Engine Efficiency

The Physics of CHP Cogeneration and Heat Engine Efficiency

How does CHP work? To understand CHP you have to begin with the Carnot cycle, and how it describes the function and efficacy of any heat engine. The thermodynamic Carnot cycle (proposed by Nicolas Carnot in 1824) is a four-stage process that describes the reciprocal operations of a heat engine
