Rooftops, deserts, and even satellites in orbit are all powered by solar energy. However, there is an intriguing aspect of solar power that is sometimes disregarded that goes beyond the panels and data. These ten hard-to-believe but unquestionably real facts about solar energy range from astounding efficiency records to space applications.
1. The world could be powered for a year with just one hour of sunlight.
Approximately 173,000 terawatts of solar energy are continuously received by the Earth. That is over 10,000 times the amount of energy used worldwide. Theoretically, we could meet the planet’s energy needs for a whole year if we could catch just one hour of sunshine.
2. Spacecraft Can Be Powered by Solar Panels
NASA has been using solar energy in orbit since 1958, so solar power isn’t just for homes and companies. Solar panels are a major source of energy for spacecraft such as the International Space Station and the Mars rovers. It’s the best renewable energy source in space, since the sun never sets.
3. The largest solar plant in the world spans more than 14,000 acres.
With an area of over 56 square kilometers (14,000 acres), the Bhadla Solar Park in India is the biggest solar installation on the planet. It can power millions of homes thanks to its more than 2.2 gigawatt capacity.
4. More solar panels are installed in China than in any other nation.
In addition to being the largest producer of solar panels, China is also the largest consumer. China has made significant investments in solar energy to combat pollution and meet climate commitments, and as of 2024, it had more than one-third of the world’s installed solar capacity.
5. Even at night, solar panels can function on overcast days.
The idea that solar panels can only function in direct sunlight is untrue. Even while they work best in clear weather, they can still produce electricity on overcast days. Additionally, you can use stored solar power at night when you have solar + battery storage.
6. The Cheapest Power in History Is Solar Energy
In many regions of the world, solar energy is currently the least expensive source of electricity ever, according to the International Energy Agency (IEA). It’s frequently less expensive than coal and natural gas because of declining panel prices and improved efficiency.
7. In 1883, the first solar cell was created.
Charles Fritts, an inventor, used selenium to construct the first solar cell long before the current clean energy movement. Despite having an efficiency of less than 1%, it set the stage for the current solar revolution.
8. The World Has Seen the Flight of Solar Planes
Without consuming any fuel, Solar Impulse 2 became the first solar-powered aircraft to complete a full orbit of the earth in 2016. Powered solely by sunshine and high-efficiency batteries, it covered more than 26,000 kilometers.
9. Using Solar Energy to Combat Drought
In addition to generating power, solar panels can help save water. Solar PV consumes almost minimal cooling water, which makes it perfect for areas that are prone to drought, in contrast to coal or nuclear reactors that require enormous volumes.
10. Roads Powered by Solar Energy Exist
Yes, there are highways that use solar energy to generate electricity. Solar-powered bike lanes and highways have been tested in nations including France and the Netherlands. Although it is still in its infancy, it offers a preview of how solar energy might change infrastructure.
In addition to being pure, solar energy is also ingenious, futuristic, and occasionally simply amazing. Solar power will continue to wow us as technology develops and the globe shifts to sustainability. The future of energy is unquestionably bright, whether it takes place on your roof or in orbit.
