Ancient history of solar energy

What is the history of solar power?

The history of solar power is a testament to human innovation and our persistent quest for sustainable energy solutions. From ancient civilizations harnessing the sun’s warmth to modern breakthroughs in photovoltaic technology, solar power has evolved into a key player in the global energy landscape.

Who invented solar energy?

The story of solar energy begins in 1839 with the work of French physicist Edmond Becquerel. In experimenting with metal electrodes and electrolyte solutions, Becquerel discovered the photovoltaic effect—the creation of electric current in a material upon exposure to light.

How did solar energy start?

It started simply – warming rooms with large windows or starting fires with mirrors – and led to today’s complex photovoltaic power plants with millions of solar panels each creating electricity. Knowing the history of solar energy gives us a deeper appreciation for just how much work it took to get us to today’s modern solar technology.

When did solar technology start?

This timeline lists the milestones in the historical development of solar technology from 1767 to 1891. Swiss scientist Horace de Saussure was credited with building the world’s first solar collector, later used by Sir John Herschel to cook food during his South Africa expedition in the 1830s.

Who discovered photovoltaic solar energy in 1838?

In 1838 photovoltaic solar energy appeared in the history of solar power. In 1838, the French physicist Alexandre Edmond Becquerel discovered the photovoltaic effect for the first time. Becquerel was experimenting with an electrolytic cell with platinum electrodes. He realized that exposing it to the sun increased the electrical current.

How was solar energy used in ancient times?

In the 7th century BC, magnifying glasses were used to start fires by concentrating the sun’s rays. And in the 3rd century BC, the Greeks and Romans redirected sunlight using mirrors as strategic defense mechanisms to set enemy ships ablaze. This early understanding of solar energy laid the groundwork for future technological advancements.
