Did Nasa Invent Solar Panels

60 years ago this week the modern solar cell came into being.

Did nasa invent solar panels.

Today a solar panel can cost as little as 0 50 a watt. You don t have to look far to see how important solar power is to nasa. One of humankind s most ambitious projects the international space station iss is dwarfed by the size of its eight 114 foot 35 meter long solar array wings. While we can pinpoint the major steps towards its invention countless researchers and scientists over the last 200 years each contributed small breakthroughs that led to the modern solar panel.

The invention of the solar cell. Who invented solar panels. When and more importantly who invented solar panels is a complex question. Dependency on foreign energy resources.

1959 hoffman electronics creates a 10 efficient commercial solar cell and introduces the use of a grid contact reducing the cell s resistance. In 1956 solar panels cost roughly 300 per watt. Naval research laboratory launched vanguard i the first spacecraft to use solar panels in 1958 and nasa launched the first satellite equipped with panels that tracked the sun nimbus i in 1964. Solar panels and solar technology has come a long way so these patented inventions are proof that the technology is still improving its efficiency and aesthetics.

It was a time of high inflation when americans were squeezed economically and shortages in essentials made the need for further innovation glaringly evident. Each wing contains around 33 000 solar cells which convert about 14 percent of the sunlight that hits them into usable energy source. Vanguard i the first solar powered satellite was launched with a 0 1w 100 cm solar panel. Government pioneered much of the early pv technology.

Researchers at nasa ames are conducting cutting edge research in the development of clean energy technologies for nasa mission needs in the exploration systems mission directorate and the science mission directorate our renewable energy focus is on advancing biofuels solar and wind technologies that also help reduce our nation s dependence on petroleum based fuels. Since the year 1980 solar panel prices have dropped by at least 10 percent every single year. In the 1970s an oil shortage brought awareness of u s.
