4.5 billion years ago, solar energy began to radiate into the earth.
In the 9th century BC, the Chinese began to use “Yang Sui”(concave mirror) to focus light for fire.
In the 7th century, solar fires were started using a convex lens.
The 3rd century BC, Greeks and Romans used “Burning mirrors”(concave mirrors) as weapons to focus the sun’s energy and ignite the sails of enemy ships.
In the 1st century, the Italian historian Pliny built the first passive solar house to insulate against heat.
Between 1 and 500, the Romans built large windows facing south in the Chamber of desire to use direct sunlight to absorb heat.
In the 6th century, List of Byzantine emperors enacted laws to protect houses and public buildings from the sun’s heat by means of solar panels.
In the 14th century, the ancestors of the North American Indians lived on the southern side of a cliff in winter to face the sun for warmth.
In the 17th century, knowledgeable people accepted the idea that the sun and other stars were the same,
the 1615 has a pump that uses solar thermal collector air to expand it to do work.
1643-1715 the reign of King Louis XIV of France of France was an era of solar experimentation.
In the 18th century, European aristocrats used solar walls to store ripe fruit, and south facing glass walls in England and Holland facilitated the development of solar greenhouses.
Swiss scientist 1767 invented the first solar collector.
1774, in Paris, France, there was a show in which the venue used a lens to focus the sun’s rays and melt metal.
In the 19th century, wealthy Europeans began to build and use solar greenhouses and insulated houses, and French scientists used the heat from solar collectors to generate steam to power steam engines.
At the 1837, British astronomer Huxley buried a black box in sand on an expedition to the Cape of Good Hope in Africa. The box was insulated with double glazing to reach 116 degrees, so he cooked with the simple solar device.
The French scientist Edmundbecquerel at the 1839 observed the photovoltaic effect of solar energy.
In 1861, the French scientist Augustine Mouchot patented the solar device.
In 1870 Augustine Mouchot used solar cookers, solar water pumps for irrigation, solar evaporators for wine and water distillation (extensive use of solar energy) . American engineer
John Ericsson has developed a solar-powered version.
1891, American inventor John Ericsson patented the first ever commercial solar water heating.
In 1892, British inventor Aubrey Eneas founded the Boston Solar Engine Company, which invented a solar powered engine to replace a steam engine powered by coal or wood.
In the 20th century, in 1901, a solar-powered water pumping unit was built in California, USA, using a truncated cone concentrator with a power of 7.36 kw.
From 1902 to 1908, the Carnegie Steel Company of Los Angeles invented the modern roof-ridge solar collector.
In 1913, south of Cairo, Egypt, a solar powered water pump consisting of five parabolic troughs, each measuring 62.5 meters long and 4 meters wide, with a total lighting area of 1,250 square meters. In 1936, American astrophysicist Charles Greeley Abbott invented the solar water heater
In 1940, there was a great demand for solar houses, both active and passive.
In 1941, about 60,000 solar water heating were used in Florida.
In 1950, the Soviet Union designed the first tower solar power station. American architect Frank Bridgers designed the world’s first solar powered office building.
In 1952, the Centre Nationale de Recherches Française built a Pyrenees in the east
50 kw solar furnace.
In 1954, the Bell Labs developed a practical type of silicon battery, which is widely used in the aerospace industry on artificial earth satellites.
In 1955, Taibo of Wu and others in Israel put forward the basic theory of selective coating at the first international scientific conference on solar thermal utilization, and developed practical selective coating such as black nickel, which created the conditions for the development of efficient collector.
In 1960, the first ammonia-water absorption air-conditioning system with a cooling capacity of 5 tons (17.6 kw) was built in Florida. In 1961, a Stryn with a quartz window was introduced.
1977: US President Jimmy. Katel installed solar panels at the White House to promote the use of solar energy systems. “Gradient film”selective absorption coating for solar evacuated collector tubes has been developed at the University of Sydney, Australia.
In 1983, Wisconsin enacted a solar energy law to protect city gardens. Arizona and Michigan passed similar laws. “Plenty of light,”and then
In 1990, about 1.5 million buildings in Tokyo, Japan, used solar water heating, about 30 percent of Israeli homes were equipped with solar water heating, and all new homes required solar hot water systems. Greece, Australia and several other countries in the use of solar energy breakthrough, such as the invention of the University of Sydney, Australia, “Interference film”selective absorption coating.
In 1992, the United Nations held the “World Sun”World Environment and Development Conference in Pakistan
In 1996, the United Nations convened the Energy Summit in Zimbabwe.
In 1997,160 countries adopted the Kyoto Protocol at the Third Conference of the parties to the United Nations Framework Convention on climate change in Kyoto, Japan.
After the 21st century, “Renewable energy law of the People’s Republic of China”was implemented, China’s solar thermal market ranked first in the world; Germany builds 33,500 solar power plants. Human solar energy industry has entered a new stage of conscious and active development and utilization
