Solar panels are an increasingly popular source of renewable energy for households and businesses across the United Kingdom. But who invented them? The answer to this question is not straightforward, as the development of solar technology has spanned centuries and continents. In this article, we will explore the history of solar panels and highlight the key figures who contributed to their invention.
The earliest record of the use of solar energy dates back to the 7th century BC, when magnifying lenses were used to focus the sun’s rays to create fire. However, it was not until the mid-19th century that the first solar cells were invented by French physicist Edmond Becquerel. Becquerel discovered that certain materials, such as selenium, produced an electric current when exposed to light. This phenomenon, known as the photovoltaic effect, paved the way for the development of solar panels.
In the early 20th century, American inventor Charles Fritts created the first true solar cell by coating selenium with a thin layer of gold. However, these cells were expensive to produce and had a low efficiency rate, meaning they could only convert a small amount of sunlight into electricity.
It was not until the 1950s that significant progress was made in the development of solar cells. American engineer Daryl Chapin, along with scientists Calvin Fuller and Gerald Pearson, invented the first practical solar cell at Bell Labs in New Jersey. This cell was made of silicon, which was cheaper and more efficient than previous materials. The team’s invention was a breakthrough, as it was the first time that solar cells could produce enough electricity to power small electrical devices.
The next major development in solar panel technology came in the 1970s, when American engineer Elliot Berman created the first solar-powered home. Berman’s home was equipped with a solar panel system that generated enough electricity to power all of the home’s electrical appliances. This experiment proved that solar energy was a viable alternative to traditional energy sources.
In the United Kingdom, solar technology began to gain popularity in the 1980s. The government introduced a Feed-in Tariff (FIT) scheme in 2010, which incentivised homeowners and businesses to install solar panels by offering them payments for the electricity they generated. This scheme led to a surge in demand for solar panels, and the UK became one of the largest markets for solar energy in Europe.
Today, solar panels are an essential component of the UK’s renewable energy mix. The country has set a target to achieve net-zero carbon emissions by 2050, and solar energy is expected to play a significant role in achieving this goal. In 2020, solar panels generated 6.5% of the UK’s electricity, and this figure is expected to grow as more households and businesses invest in solar technology.
In conclusion, while there is no one individual who can be credited with inventing solar panels, the development of this technology has been a collective effort spanning centuries and continents. From the discovery of the photovoltaic effect by Edmond Becquerel to the invention of the first practical solar cell by Daryl Chapin, solar technology has come a long way. Today, solar panels are an essential component of the UK’s renewable energy mix, and their contribution to reducing carbon emissions cannot be overstated.
