Solar energy panels history.

It was a time of high inflation when americans were squeezed economically and shortages in essentials made the need for further innovation glaringly evident. In 1958 the vanguard i satellite used a tiny one watt panel to power its radios. Solar cells begin to power navigation warning lights and horns on many. Solar energy is radiant light and heat from the sun that is harnessed using a range of ever evolving technologies such as solar heating photovoltaics solar thermal energy solar architecture molten salt power plants and artificial photosynthesis.

Later that year the vanguard ii explorer iii and sputnik 3 were. Because the intensity of solar radiation at earth s surface is so low these collectors must be large in area. Solar panels in outer space some of the earliest uses of solar technology were actually in outer space where solar was used to power satellites. Among the most common devices used to capture solar energy and convert it to thermal energy are flat plate collectors which are used for solar heating applications.

Dependency on foreign energy resources. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. We could meet all of the power needs of the united states by placing solar panels on just 11 2 million acres of land. Elliot berman with help from exxon corporation designs a significantly less costly solar cell bringing price down from 100 a watt to 20 a watt.

Other major events in the history of solar energy. Solar power is the conversion of energy from sunlight into electricity either directly using photovoltaics pv indirectly using concentrated solar power or a combination concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam. This featured an 8 story parabolic mirror. Even in sunny parts of the world s temperate regions for instance a collector must have a surface.

Solar panels as a viable energy alternative. Solar energy wind alternative power products services for residential commercial and industrial systems. In the 1970s an oil shortage brought awareness of u s. Photovoltaic cells convert light into an electric current using the photovoltaic effect.

In just two hours more energy from the sun falls on the earth than the entire human population consumes in a year. The solar heating and cooling demonstration act of 1974 ordered the installation of solar heating and cooling units in federal buildings by 1977 to acclimate the public to the new technology.
