- Space exploration played a key role in advancing solar technology.
- Solar power is now a major player in the global transition to clean energy.
When Was Solar Energy First Used?
Humans have been using solar energy for thousands of years, and it all started with some clever ideas.
Ancient Greeks and Romans were the original solar innovators. They designed buildings to capture sunlight for warmth, a technique called passive solar architecture. If you visit ancient ruins, you can still see signs of this design.
By the 2nd century, Romans advanced solar heating by using specially designed windows to direct sunlight into bathhouses. This kept the water warm and was an early example of solar heating.
In 1767, Swiss scientist Horace de Saussure made a breakthrough by inventing solar collectors that stored heat. These eventually became the first solar ovens for cooking.
The 19th century brought a game-changing discovery. In 1839, a French physicist uncovered the photovoltaic effect, the basis for modern solar cells.
By the 1950s, solar technology took a major step forward when Bell Labs developed the first practical solar cell in 1954. This innovation paved the way for the solar panels we use today.
From heating Roman baths to powering modern homes, solar energy has come a long way. It’s a story of creativity and progress that continues to evolve.
When Were Solar Panels Invented?
The story of solar panels goes back further than you might think. In 1839, a young French physicist named Alexandre Edmond Becquerel discovered the photovoltaic effect, the key to turning sunlight into electricity.
For the next century, scientists experimented with this discovery, trying different materials and methods to harness solar power. The big moment came in 1954 when Bell Labs created the first practical solar cell, capable of converting about 6% of sunlight into electricity.
Back then, solar panels weren’t cheap. In 1956, one watt of solar power would set you back around $300. By 1975, prices had dropped to about $100 per watt. Today, you can get the same watt of power for less than a dollar.
The space race played a huge role in advancing solar technology. NASA used solar panels to power satellites and space stations, driving innovation that made solar tech more efficient and accessible.
Now, solar panels are everywhere, from rooftops in your neighborhood to powering homes, businesses, and entire communities worldwide. What started as an idea in a lab is now a key part of how we power our lives.

1888: First U.S. Patent for Solar Cells
Just five years later, solar technology got its official stamp of approval. Edward Weston received the first U.S. patent for a solar cell.
This formal recognition was a big deal. It encouraged more scientists and inventors to explore solar energy. The patent system protected their ideas, spurring further innovation.
1905: Einstein’s Photoelectric Effect Paper
In 1905, a young Albert Einstein shook up the scientific world. He published a paper explaining the photoelectric effect.
Einstein’s work provided a scientific basis for understanding how solar cells work. It helped other researchers improve solar technology. This paper also earned Einstein the Nobel Prize in Physics in 1921.
1954: First High-Power Silicon Solar Cell
A major breakthrough came in 1954. Scientists at Bell Labs developed the first high-efficiency silicon solar cell.
This new cell could convert 4% of sunlight into electricity. It was a huge jump from earlier designs. This innovation made solar power much more practical for real-world use.
1963: Mass Production Begins
In 1963, solar energy took a big step towards the mainstream. Sharp Corporation started mass-producing silicon solar panels.
