1981 - Fraunhofer Institute for Solar Energy Systems ISE is founded by Adolf Goetzberger in Freiburg, Germany. [19] 1981 - Isofoton is the first company to mass-produce bifacial solar cells based on developments by Antonio Luque et al. at the Institute of Solar Energy in Madrid. [20] 1982 - The first >10% amorphous silicon thin film solar cell ...
By the 1960s solar power was the standard for powering space-bound satellites. In the early 1970s, solar cell technology became cheaper and more available ($20/watt). Between 1970 and 1990, solar power became more commercially operated. Railroad crossings, oil rigs, space stations, microwave towers, aircraft, etc.
Dozens of pattern books were published in this period, including the Passive Solar Energy Book by Edward Mazria. [11] In 1977, the U.S. Department of Energy was created, and in 1978 Solar Energy Tax credits were provided. In 1979, President Carter installed solar panels on the roof of the White House.
MIT Solar House #1 The following buildings are of significance in pioneering the use of solar powered building design: MIT Solar House #1, Massachusetts, United States (Hoyt C. Hottel & others, 1939) Howard Sloan House, Glenview, Illinois, United States (George Fred Keck, 1940) "Solar Hemicycle", near Madison, Wisconsin, United States (Frank Lloyd Wright, 1944) Löf House, Boulder, Colorado ...
To increase the specific power, typical solar panels on spacecraft use close-packed solar cell rectangles that cover nearly 100% of the Sun-visible area of the solar panels, rather than the solar wafer circles which, even though close-packed, cover about 90% of the Sun-visible area of typical solar panels on Earth. However, some solar panels on ...
Hoffman KP706 Trans Solar Radio (1959), running on batteries or with a Hoffman solar cell array on the top. Hoffman made great strides in making the solar cell a practical and useful source of renewable energy. From 1957 to 1960, he improved its efficiency from 4.5 to 14 percent and lowered the production cost to make it a marketable item.
The Tata group, one of India’s largest conglomerates, promised to be a good neighbor when it took on the job of building the nation’s first “ultra mega” coal-fired power plant. Find Out First ICIJ and The Huffington Post estimate that 3.4 million people have been physically or economically displaced by World Bank-backed projects since 2004.
On June 20, 1979, 32 solar water heating panels were placed on the roof of the West Wing.The panels were made by InterTechnology/Solar Corp. from Warrenton, Virginia and installed by Hector Guevara of Alternate Energy Industries Corp. [2] At the dedication ceremony for the panels, President Carter said, "In the year 2000 this solar water heater behind me, which is being dedicated today, will ...
