History of Solar Energy
Ancient History of Solar Energy
Modern History of Solar Energy
In the late 1700s Swiss scientist Horace de Saussure invented the world’s first concentrated solar collector, which was later used for cooking food.
In 1839 French scientist Edmund Becquerel discovered the photovoltaic effect by showing that the electrical generation of his prototype increased when exposed to the sun’s light, this was a huge discovery for the history and future of solar energy.
In the 1860’s the solar powered steam engine was invented and was used for many different applications.
In 1905 Albert Einstein wrote a paper of the photoelectric effect, greatly improving the world’s knowledge of the topic, and for which he later won the Nobel Prize. Then, in 1908 William J Bailey invented a solar collector with copper coils and an insulated box, which is still the foundation of the construction of solar panels today.
It was not until 1953 that the modern day photovoltaic (PV) cell was constructed and able to harness enough of the Sun’s energy to run common electrical appliances. The PV cell model is now the most efficient contributor to solar power today.
The most monumental discovery in the history of solar power was the discovery of the photovoltaic effect. This discovery has greatly influence solar panel design and the solar power technology of today.
