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.

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.

Where did solar energy come from?

The story of solar energy begins with our ancestors. The early uses of solar energy were primarily passive, relying on the sun’s heat for warmth and drying. Ancient civilizations had a deep understanding of the sun’s power and harnessed it in their daily lives. The Greeks, for instance, were known for their solar architecture.

What are the most ingenious inventions in the history of solar energy?

We take a look at the six most ingenious inventions in the history of solar energy. From the sundial to the Fritts solar panel, stopping off at the first Roman greenhouses and the Becquerel cell on the way.

How did solar technology develop in the 19th century?

The 19th century marked significant scientific advancements that laid the groundwork for modern solar technology: Edmond Becquerel’s Discovery (1839): French physicist Edmond Becquerel discovered the photovoltaic effect, the principle underlying solar cells.

How did humans use solar energy?

Similarly, the Romans improved upon this concept by using glass windows in their bathhouses to trap solar heat. In the 7th century B.C., humans discovered that sunlight could be concentrated using a magnifying glass to create fire. This marked one of the earliest instances of humans manipulating solar energy for a specific purpose.
