Solar energy is a fascinating topic that has been studied and utilized for centuries. Over the years, it has become increasingly popular as a renewable and sustainable energy source.
Most people know that solar power is generated from the sun’s energy, but there are many interesting and fun facts about solar energy that you may be surprised to learn.
Fun Facts About Solar Energy
It’s good for the environment, it can save you money, it increases home value — these are facts about solar energy that you probably already know. But there is a lot more to learn! Here are five fun facts about solar energy that may surprise you:
1. Solar Energy Is the Most Abundant Energy Source on Earth
The amount of solar energy that reaches Earth in just one hour is so powerful that it is enough to power the world for an entire year. The sun’s scale of opportunity is so extraordinary that it means that every natural gas out there could be left in the ground unmined if we could capture just an hour’s worth of solar energy every year.
For context, if we were to cover the Mojave Desert with solar arrays, we would get nearly three times as much electricity as we use annually.
2. A French Scientist Named Alexander-Edmond Becquerel Invented the First Solar Cell in 1839
Becquerel discovered the photovoltaic effect in 1839, which is the ability of certain materials to convert light into electricity. While the first solar cells were not very efficient, they laid the foundation for future advancements. The modern solar cell, made of silicon and much more efficient, was first created in 1939 by Russell Ohl and developed in 1954.
3. The First Solar-Powered Calculator Was Invented in 1978
The calculator, known as the Casio Mini, was the first device to use a small solar cell to generate electricity. The solar cell was integrated into the calculator’s design, which allowed it to charge the device when exposed to sunlight. The calculator became very popular because it didn’t require batteries, making it more convenient and environmentally friendly.
4. The Cost of Solar Panels Has Decreased by 99% Since 1977
The high cost of solar panels was one of the major barriers to adopting solar energy. In 1977, one simple solar cell cost $77 per watt. However, solar power has become increasingly affordable over the years, thanks to technological advances, economies of scale, and friendly government policies.
According to the Solar Energy Industries Association and GTM Research’s Q3 2017 Solar Market Insight Report, it now costs $0.21 per watt for a solar cell and $0.39 per watt for an entire assembled module.
5. The Solar Industry Employs More People in The United States Than Coal Mining
The solar industry has been one of the fastest-growing job markets in recent years. According to a 2018 report, the solar industry employed nearly 335,000 workers in 2018, while the coal mining industry employed around 211,000 workers in the same year.
Own a Solar Panel and Save Money
Solar panels have a lifespan of about 30 years. Although the initial cost might be high, you typically begin recouping your investment within the seventh year, meaning you’ll save money in the long run. Solar panels allow you to put money back into your pocket and do your part for the environment, and Solar Optimum can help. Contact us today for a free quote and join the movement.
