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.

IAPMO Seeks USEHC Geothermal Piping and Photovoltaic Task Group Members

The International Association of Plumbing and Mechanical Officials (IAPMO®), publisher of the Uniform Solar Energy and Hydronics Code (USEHC), is accepting applications and seeking technical experts to participate on task groups relating to geothermal piping and photovoltaic systems.

The scope of the Geothermal Piping Task Group is to review Items 97,

Transforming Landfills Into Resources

Transforming Landfills Into Resources

A landfill can be like a baby: It is helpless to care for itself; while it’s growing, it eats all day; at night when resting, it must be protected from the elements; and it belches constantly. If you’re lucky, it won’t stir up much fuss. If you’re not lucky, the neighbors

Project Profile – Microgrid Technology

Nearly 25 years ago, Caterpillar opened a proving ground about 30 miles southwest of Tucson, AZ. The facility consists of large open-air test areas, where Caterpillar conducts field trials of many of its large mining equipment before being brought to market. The proving ground site also includes workshops and an office building.

Financing Solar and Energy Storage in Schools

Financing Solar and Energy Storage in 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.

Energy Management Systems

To exemplify the evolving nature of energy management systems, Greg Turner, vice president for Honeywell Business Solutions, recalls a recent conversation in which a hospital facilities manager spoke of how he’d have to come up with budget figures once a year that would either be accepted or rejected.

“Now I get calls almost

Editor’s Comments: Leading the Orchestra

I  recently listened in amazement as Gustavo Dudamel conducted the Los Angeles Philharmonic in Tchaikovsky’s Violin Concerto in D major. As the interplay of perfectly executed notes and pleasant harmonies filled my senses, I wondered about the role a conductor plays as leader of an orchestra. I could see that each

Zero Energy Schools

Zero Energy Schools

Buildings account for nearly 40% of the nation’s energy use. Why does this matter? Because it means that while buildings are a big part of our energy challenge, they also have the potential to be a major part of the solution to a clean energy future. That’s why the US

Solar Photovoltaic System from Caterpillar Installed in Rantoul, IL

Caterpillar Inc. today announced that Cat® dealer Altorfer has commissioned a 1000 kW solar photovoltaic (PV) system in Rantoul, Illinois. Built to fulfill a 20-year power purchase agreement with the Illinois Municipal Electric Agency (IMEA), the installation was constructed on an eight-and-a-half-acre site near Heritage Lake Park and the University
