A lot of us are now familiar with modern solar energy. The power of the sun is increasingly being harnessed to produce electricity. Despite the current popularity of solar energy, many might not know that the history of solar energy dates back many centuries. This is as far as the 7th century B.C. However, it is a technology that has kept on improving. So, briefly this history of solar energy will highlight how humans have been making use of this renewable energy type.


The History of Solar Energy Began With Magnification

From the 7th century B.C. ancient civilization discovered that they could light fires using solar energy and glass. Although this seem to become very far from turning into solar energy, it indicates how long man has been fascinated by the power of the sun. windows were strategically placed to be heat by the sun light in order to heat up homes and bathhouses. I guess the love to further harness the energy of the sun really began from here.


The Photovoltaic Effect in the 19th Century

In 1839, scientist, alexander Edmond Becquerel discovered the photovoltaic effect. The first patents for solar collectors became obvious during this era. And of course Scientist, alexander Edmond continued to experiment with electrolytic cells. From here, he realized that more electricity is produced when more cells are exposed to light. Great achievements were made science by 1876. Significantly, scientists realized that selenium could convert light into electricity without the need for heat.

Thereafter, the first solar cell with selenium was developed 7 years after in 1883. As a result, this gave birth to many more progress. The first solar water heated was developed and patented in 1891. This is where the real foundation of modern solar energy was laid.

The Creation of the Solar Cell

The very first solar collector which has resemblance to today’s solar collectors was invented in 1908. The shortage of energy during World War 2 led to the embracement of passive solar buildings in the USA. Subsequently, it led to the first development of silicon photovoltaic cell in 1954. The advantage of this to the first selenium is its ability to generate enough powering for electrical equipment.

Form here, water heating in commercial properties began through the use of solar technologies. This is why solar still powers satellites today. Solar cells became an integral aspect of the design of satellites.

By now, solar panels were not yet commercialized until 1970 when engineers developed silicon cells which happens to be a cheaper option. Solar panels became suitable for domestic usage and the technology continued to gain momentum as the widespread  and possibilities of many different applications became feasible.

The solar energy technology continued to be improved upon. Cars and aeroplane could now be powered by solar energy. Solar farms became popular due to their capacity to generate energy in large scale.


A Solar Generation

Solar energy has proven to be the best option as non-renewable fossil fuels and other forms of energy continues to cause environmental pollution and more expensive to maintain. Countries like Nigeria has embraced the solar generation. It is becoming rampart to see newly constructed buildings having solar panels installed on their roof top as part of the basics of the building project. The aim is to make solar more affordable and accessed by every home and office.

As part of our goal to make solar energy affordable and accessible to everyone, we have introduced the installment payment plans where you are allowed to make installment payment and own the solar system.
