The Edward B. Bunn, S.J. Intercultural Center commonly known as the Intercultural Center or ICC is a seven-story mixed use building on the main campus of Georgetown University named for Edward B. Bunn. The center was built in 1982 as the Photovoltaic Higher Education National Exemplar Facility in conjunction with a grant from the U.S. Department of Energy. [2]
The facility hosts numerous administrative offices, student facilities, and conference spaces, but is best known for its contribution to solar power development. Among the occupants of the building are the Edmund A. Walsh School of Foreign Service, the Center for Contemporary Arab Studies, the Prince Alwaleed Bin Talal Center for Muslim-Christian Understanding, and several departments of Georgetown College. [3]
In 1980, Georgetown University applied to the Department of Energy for a grant to fund the construction of an intercultural center that would showcase the potential use building integration of photovoltaic panels to produce electrical power. [4] While the Congressional funding for the solar panels came as a result of heightened awareness of energy issues following the 1973 oil embargo, the funding for the structure itself came as a result of Georgetown's goal of improving American education in foreign languages and international affairs, which was deemed deficient in the post-Vietnam era. [5] This was part of Georgetown's effort at the time to secure federal funding for model projects that could be replicated at other universities and institutions across the nation. [6]
Construction began in early 1980 and the building itself was completed in May 1982 at a cost of $23,000,000. [2] The interior of the building consists of six floors of educational space and a seventh maintenance floor, altogether totaling 226,000 square feet (21,000 m2). While at the time the center was considered futuristic, a "dark spaceship" on the historic campus, it has since become incorporated into the campus with its Red Square courtyard serving as a student gathering area.

In its original plans it would have been the largest photovoltaic installation in the world and as completed was one of the largest ever constructed. [5] [8] At its peak it produced 360,000 kilowatt-hours (1.3×109 kJ) per year of electrical power, however with age, its current generation is approximately 200,000 kilowatt-hours (720,000,000 kJ) per year, or 6% of the structure's needs. [9] [10] Additionally, the solar panels that were installed used a rough glass that reduced efficiency, but prevented glare from affecting airplanes operating out of nearby Reagan National Airport. [8]
While it had been designed with the installation of solar panels in mind, they were not installed until late 1984 by the Solarex Corporation at a cost of approximately $10,000,000. [11] Solarex installed the 35,710 square feet (3,318 m2) of solar panels on the roof of the center facing south. [8] Solarex was later purchased by the Amoco oil company and sold in 1995 to the Enron energy company. [12] The center has been recognized as being ahead of its time in the promotion of renewable energy sources and for continuing to operate as designed, decades after its construction. [13]

In the 19th century, it was observed that the sunlight striking certain materials generates detectable electric current – the photoelectric effect. This discovery laid the foundation for solar cells. Solar cells have gone on to be used in many applications. They have historically been used in situations where electrical power from the grid was unavailable.
Solar power is a major contributor to electricity supply in Australia. As of December 2023, Australia's over 3.69 million solar PV installations had a combined capacity of 34.2 GW photovoltaic (PV) solar power. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 12.4% of Australia's total electrical energy production in 2021.
BP Solar was a manufacturer and installer of photovoltaic solar cells headquartered in Madrid, Spain, with production facilities in Frederick, MD, India and the People's Republic of China. It was a subsidiary of BP.
Spain is one of the first countries to deploy large-scale solar photovoltaics, and is the world leader in concentrated solar power (CSP) production.
The Solar Ark (ソーラーアーク) is a Japanese ark-shaped solar photovoltaic power generation facility which offers activities to cultivate a better appreciation of solar power generation, and thereby benefitting both ecology and science. This 315-meter-wide, 37-meter-tall facility is located in Anpachi, Gifu Prefecture, in the geographical center of Japan, and can be seen from the JR Tōkaidō bullet train, which runs past on an adjacent railway. It has over 5000 panels that produce approximately 530,000 kilowatt-hours on an annual basis and a maximum system power of 630 kilowatts.
Solar power includes solar farms as well as local distributed generation, mostly on rooftops and increasingly from community solar arrays. In 2023, utility-scale solar power generated 164.5 terawatt-hours (TWh), or 3.9% of electricity in the United States. Total solar generation that year, including estimated small-scale photovoltaic generation, was 238 TWh.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. Many utility-scale PV systems use tracking systems that follow the sun's daily path across the sky to generate more electricity than fixed-mounted systems.
The use of solar energy began in Israel in the 1950s with the development by Levi Yissar of a solar water heater to address the energy shortages that plagued the new country. By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold. With the 1970s oil crisis, Harry Zvi Tabor developed the prototype of the solar water heater now used in over 90% of Israeli homes. There are over 1.3 million solar water heaters installed as a result of mandatory solar water heating regulations.
Solar power has been growing rapidly in the U.S. state of California because of high insolation, community support, declining solar costs, and a renewable portfolio standard which requires that 60% of California's electricity come from renewable resources by 2030, with 100% by 2045. Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.
Housing at Georgetown University consists of 13 residence halls at the main campus and a law center campus. Housing on Georgetown's main campus is divided between "halls," usually more traditional dormitories, and "villages", usually less traditional apartment complexes. In addition, Georgetown operates many townhouses in the Georgetown neighborhood, usually for second, third, and fourth-year students.
The Hoya de Los Vicentes Solar Plant is a photovoltaic power station in Jumilla, Murcia in Spain. The solar park covers area of some 100 hectares and comprises a group of 200 photovoltaic arrays with a total capacity of 23 MW. A total of 120,000 solar panels have been installed in the facility. The project generates energy equivalent to the annual consumption of 20,000 households.
Natural Bridges National Monument Solar Power System is an experimental electrical power plant at the Natural Bridges National Monument in the southeastern portion of the U.S. state of Utah. It consists of 256,812 solar cells arranged in 12 rows, each measuring 200 feet (61 m) long. Direct current energy from the array is converted to alternating current at an equipment building, then supplied to the park's staff buildings and visitor center. Excess energy is stored in a bank of batteries that is used on cloudy days. The system is controlled by computers and creates fewer emissions than the diesel generators that it replaced.
A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters battery storage systems, charge controllers, monitoring systems, racking and mounting systems, energy management systems, net metering systems, disconnect switches, grounding equipment, protective devices, combiner boxes, weatherproof enclosures and other electrical accessories.
Solar power in Ohio has been increasing, as the cost of photovoltaics has decreased. Ohio installed 10 MW of solar in 2015. Ohio adopted a net metering rule which allows any customer generating up to 25 kW to use net metering, with the kilowatt hour surplus rolled over each month, and paid by the utility once a year at the generation rate upon request. For hospitals there is no limit on size, but two meters are required, one for generation, the other for utility supplied power.
Solar power in New Hampshire provides a small percentage of the state's electricity. State renewable requirements and declining prices have led to some installations. Photovoltaics on rooftops can provide 53.4% of all electricity used in New Hampshire, from 5,300 MW of solar panels, and 72% of the electricity used in Concord, New Hampshire. A 2016 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 9 years, and generate a profit of $34,196 over the rest of its 25-year life. A loan or lease provides a net savings each year, including the first year. New Hampshire has a rebate program which pays $0.75/W for residential systems up to 5 kW, for up to 50% of the system cost, up to $3,750. However, New Hampshire's solar installation lagged behind nearby states such as Vermont and New York, which in 2013 had 10 times and 25 times more solar, respectively.
Solar Liberty is an American company that installs, sells and leases solar panel energy systems, known as photovoltaic (PV) systems, for homes, businesses, schools, universities, municipalities, non-profits, and other facilities and properties.
A solar bus or solar-charged bus is a bus that is powered exclusively or mainly by solar energy. Solar-powered bus service is referred to as a solar bus service. The use of the term "solar bus" normally implies that solar energy is used not only for powering electric equipment on the bus, but also for the propulsion of the vehicle.
