The Dawn of Solar Utilization: Ancient Civilizations

Solar energy has been harnessed by humans since the 7th century B.C., when rudimentary techniques like magnifying glasses were used to light fires. By the 3rd century B.C., the Greeks and Romans had escalated the technology, using mirrors to focus sunlight for religious ceremonies. In China, similar practices were documented as early as 20 A.D., referred to as “burning mirrors.”

The Architectural Integration: Sunrooms and Cliffside Abodes

In the medieval era, solar energy found its way into architecture. Sunrooms with large windows were designed to direct sunlight into specific areas. Iconic Roman bathhouses often featured these sunrooms, especially those on the south-facing sides of buildings. The Anasazi ancestors in the 1200s A.D. took it a step further by constructing cliffside homes to capture the sun’s warmth during winter.

The Scientific Milestones: From Selenium to Silicon

The scientific journey of solar panels is a tale of iterative advancements. Edmond Becquerel, a French scientist, is credited with the discovery of the photovoltaic effect in the 19th century. This led to the development of selenium-based solar cells. However, the modern solar cell owes its existence to Daryl Chapin, Calvin Fuller, and Gerald Pearson at Bell Labs, who in 1954 developed the first silicon-based photovoltaic cell.

Solar Energy Beyond Earth: Powering Satellites

The 1960s saw the application of solar technology in space exploration. Vanguard I, launched in 1958, was the first satellite to be powered by a tiny one-watt solar panel. This was followed by more advanced solar-powered satellites like Nimbus in 1964 and the world’s first orbiting astronomical observatory in 1966.

Residential Solar: The First Solar Building

In 1973, the University of Delaware constructed “Solar One,” the first solar-powered building. This innovative structure utilized both solar thermal and solar PV power, pioneering the concept of building-integrated photovoltaics (BIPV).

Efficiency Breakthroughs: Setting New Records

From Hoffman Electronics’ 8% efficient cells in the late 1950s to the University of South Wales’ 34.5% efficiency rate in 2016, the journey of solar conversion efficiency has been remarkable.

Solar Aviation: Touching the Sky

Solar-powered aircraft have also made headlines. Solar Challenger, built in 1981, flew from France to England solely on solar power. Solar Impulse 2 completed the first zero-emission flight around the world in 2016.

The Presidential Influence: White House Installations

Solar panels were first installed on the White House in 1979 during Jimmy Carter’s presidency. Although removed by Ronald Reagan, they were reinstalled in 2010 under Barack Obama’s administration.

Affordability: The Game Changer

One of the most significant shifts in solar adoption has been its decreasing cost. From $300 per watt in 1956 to as low as $0.50 a watt today, the affordability of solar panels has been a driving force in its widespread adoption.
