Interesting Facts of Solar Energy

1. INTERESTING FACTS ABOUT SOLAR ENERGY

2. Discovery of Photovoltaic Effect The photovoltaic effect was discovered by a 19-year-old French boy, Edmond Becquerel in 1839. He observed that upon exposure to light radiations, some elements produce electricity.

3. First Practical Solar Cell The first-ever solar cell was invented by Bell Laboratories, New Jersey, in 1955. This cell had an efficiency of 6 percent which was a breakthrough at that time.

4. One hour of sunlight can produce enough electricity for humanity to use for a year Sun is the ultimate source of renewable energy in our solar system. It is a big ball of burning gases emitting lots of energy every single moment. Energy emitted by the sun in an hour can provide sufficient electricity which humanity can use for a year. Every hour Sun releases 430 quintillion joules of energy while humanity’s need for a year makes up 410 quintillion joules a year. That means the sun gives more than enough energy to fulfill our needs. (FYI, quintillion has 18 zeros)

5. Reduced CO2 Emissions A solar-powered home can alone reduce the carbon emission in the environment by up to 100 tons within 30 years.

6. 99% decrease in Solar Panel price The price of electricity has increased by more than 20% in Pakistan while the Solar Panel Price in Pakistan and all over the world has decreased by 99% since 1977.

7. Rooftop Solar reduces the Burden off the grid In Victoria, Australia, residential solar panel systems of around 100 KW are adding up to 1100 MW of electricity to the national grid. If a large number of home and business owners start using rooftop solar panels, it can help take the burden off the grid and provide uninterrupted supply to other users.

8. China, the World Solar Leader With more than 78 GW of solar installations, China has become the world leader in solar installations. China is likely to surpass 100 GW solar installations very soon which will be enough to power more than 15 million houses in Pakistan.

9. The Surface Area to power the Globe The surface area needed to be covered with Solar Energy Panelsfor the production of enough energy to power the entire planet earth is no more than the surface area covered by Spain.

10. Solar Power pays for itself By switching to solar power, people do not have to pay their electricity costs and they can even earn cash by selling excess electricity. In this way, a Solar Systempays for itself. Usually, within 5-10 years a person can easily get the return on investment in solar energy with at least 15-20 years remaining to enjoy the benefits.

11. Clean Green Energy Sunlight gives life to plants by letting them prepare their food. Sunlight has no adverse effect on the climate. Sun is a source of renewable energy that does not pollute the environment in any way, making solar systems the safest energy generation method.

12. Solar Stadiums Nations around the world are beginning the construction of stadiums with thousands of solar plates installed which power the houses and businesses when there is no event going on inside.

13. Reliability for decades Typically a solar panel system can stay in a working condition for up to 4 decades or 40 years. Most Solar Companiesprovide maintenance and warranty for at least up to 25 years.
