Discovering the Origins of Solar Power: The Earliest Known Methods
Solar power has become a common term in today's world, with the increasing demand for renewable sources of energy. However, not many know the origins of this amazing technology that harnesses the power of the sun. The use of solar power dates back to centuries ago, with some historical accounts dating back to ancient Greece and Egypt.
The Greeks were known to use burning mirrors made of polished bronze or copper to concentrate the sun's rays on a single point. This created intense heat that was used to start fires for religious offerings or to ignite kindling for cooking fires. The Egyptians, on the other hand, used passive solar designs in their architecture to capture the sun's warmth during the day and retain it throughout the night.
However, it was not until the 19th century that scientific research on solar power began. In 1839, French physicist Alexandre Edmond Becquerel discovered the photovoltaic effect, which is the process of converting sunlight into electricity using silicon. From there, numerous developments were made, leading to the discovery of the first modern solar cell in 1954 by Bell Laboratories.
Today, solar power is used in a variety of applications such as residential and commercial buildings, transportation, and even space exploration. With its numerous benefits such as zero emissions, low maintenance costs, and reliable performance, solar power is undoubtedly one of the most promising sources of renewable energy for our future.
If you want to learn more about the fascinating history of solar power and its many uses, keep reading this article. We'll delve deeper into the earliest known methods of harnessing the power of the sun and how they paved the way for the advanced technology we have today.

Introduction
Solar power is known to be one of the most efficient and cost-effective sources of energy in the world. However, the solar industry did not become what it is today overnight. The history of solar power dates back centuries, and it has undergone a series of significant changes since then. In this article, we will uncover some of the earliest known methods of using solar power.
Ancient Civilizations
Several ancient civilizations, including the Greeks and Romans, used passive solar design principles to heat their homes and buildings. They would build their homes facing south to maximize solar absorption and use materials such as adobe or stone to store and radiate heat.
Ancient China
Ancient China was also one of the earliest civilizations known to have used solar energy. They built their homes with large south-facing windows to capture the sun's rays during the winter months. Moreover, they made use of mirrors that could concentrate the sunlight to create fire and heat.
The Discovery of Photovoltaics
The discovery of photovoltaics, also known as solar cells, was in 1839 by Alexandre Edmond Becquerel. He discovered the photovoltaic effect, which is the ability of certain materials to convert sunlight into an electrical current. Becquerel's discovery was the foundation of modern-day solar cells.
The Solar Water Heater
In 1891, Clarence Kemp invented the first commercial solar water heater. He mounted copper tubing on a black painted wooden box, using the sun's energy to heat water for residential use. The solar water heater is still in use today with many modern technologies incorporated.
Solar-Powered Steam Engines
In 1860, French mathematician, Auguste Mouchout developed the first solar-powered steam engine. He made a solar concentrator that could produce steam, powering an engine. His invention became very popular until fossil fuels took over, but now this technology is making a comeback.
Solar Energy in Space
The first solar panels sent into space were aboard the Vanguard I spacecraft launched in 1958. Since then, solar energy has become popular for use on satellites and spacecraft due to their reliability and efficiency in generating power.
Solar Power Today
Today, solar power is one of the fastest-growing sources of renewable energy. The falling costs of solar panel systems, governmental incentives, and public demand have all contributed to an increase in the industry's growth. According to reports, renewable energy sources including solar power will generate more electricity than coal by 2021.
