4. First Use of PV was in 1939

French scientist Edmond Becquerel first recognized the PV effect in 1839 when he realized power generation from an electrolytic cell increased after exposure to light.

5. Solar Panels to Not Need Direct Sunlight to Charge

Solar energy detractors frequently assert that all it takes is one cloudy day for the power to go off. While it is true that solar panels are less effective in cloudy conditions, this does not imply that they are ineffective. On a cloudy day, solar panels are still only 40% efficient. 

6. Solar is the Ultimate Source of Renewable Electricity

Solar energy is converted into electricity using photovoltaics or concentrated solar power. The photovoltaic system utilizes the photoelectric effect to transform solar energy into electrical energy.

7. No Need for Ongoing Resource Consumption

After solar panels are established, maintenance expenses are minimal compared to conventional power-producing methods. It may produce enormous volumes of electricity without the cost and constant nudge of getting a fuel supply.

8. Solar Can Power Your Entire Home 

Solar energy can be used to power lighting, air conditioners and space heaters, water heaters, ventilation fans, and more electric appliances. It is the safest and greenest option to run your home, and modern solar technology and batteries make it easy to have your whole home running on solar. 

9. Solar Farms Can Provide Energy to the Grid 

A solar farm is a vast gathering of photovoltaic (PV) solar panels that collect energy from the sun, convert it into electricity, and deliver that to the power grid for distribution and consumption by consumers like you.

Solar farms, also known as solar parks or photovoltaic power plants, can be any size and shape and are typically mounted to the ground rather than on rooftops.

10. Solar  is Effective All Year – Even in Winter

You may believe that your solar panels would produce less electricity when the weather becomes colder, but that is simply untrue. In actuality, winter is also a better time to use solar panels. The white snow reflects sunlight, assisting the solar panels in capturing it.

Your panels won’t be able to collect anything, though, if they are coated with snow. The panels are tilted in part because of this. The snow will start to melt and slide off on its own!

11. The Space Industry was the First to Use Solar Energy

One of the earliest sectors to embrace renewable technologies was the space sector.

The space industry started utilizing renewable technology to power spaceships in the 1950s. The oldest man-made spacecraft in orbit, Vanguard 1, the first artificial satellite powered by solar cells, has traveled more than 6 billion miles.

As well as for large-scale ground systems that produce clean electricity from sunshine, panels are now a typical component on satellites and rovers exploring other worlds like Mars or Venus. The International Space Station is entirely solar-powered.

12. Solar is the Most Accessible Renewable Energy Source

Solar power generation is relatively easy and basic compared to other energy-gathering methods. Grid-tied systems can be installed in as little as one day and integrate seamlessly with current electrical infrastructure.

13. Solar is Also Great as a Temporary Power Solution

Solar energy is also rising in popularity when there is a temporary demand for electricity. Places like mining locations, regional and state fairs, and occasions like the Olympics use solar energy in their temporary set-up.

14. Top Producers of Solar Energy Include China, US and EU

More than 48 GW of photovoltaic (PV) capacity was installed in China, the world’s leading producer of solar energy, in 2020.

Top solar producers include the United States, Vietnam, Japan, the EU, and the US.

15. Solar Plants Can Stay in Use for Up to 40 Years 

After a solar power plant is built, it enters into a power supply agreement with its clients that is typically good for 20 to 25 years. This implies that a solar energy plant must operate for more than 20 years after it is created.

Additionally, solar panels may last for 40 to 50 years in total. After that, more advanced and efficient panels might be installed in their place. Solar panel installation can be a significant investment, but it is well worth it.

16. Rural Economies Benefit from Solar Power

Rural locations, where ranchers and farmers often desire to diversify their income, are where you’ll find most utility-scale solar farms. Landowners receive rent payments for the use of their property. It gives them a reliable source of supplementary income that enables them to carry on their farms and ranches to the next generation.

Solar energy is a desirable new income crop to support ranching, farming, and other activities. Additionally, many local governments use the additional tax income generated by solar farms to pay for urgently required road, school, and bridge repairs.

17. Solar Increases Your Property Value

One more notable fact about solar energy is that your electricity costs would be reduced if solar panels were installed in your home or business. Most of the time, you’ll even get paid for the energy your system generates.

 Additionally, there are many tax breaks and rebates available that are intended to promote solar energy use while also saving homeowners money.

Frequently Asked Questions

How does Solar Energy Function at Night? 

Does going solar mean that you won't have power at night because your solar panels won't function if the sun isn't out? Obviously not! Even while using solar energy, you remain connected to the grid. The grid and the solar system function together. Your solar system generates more energy during the day than is required for your home to operate at that time. Your meter records the extra that is returned to the grid as the excess. Check out the full guide for more info on how Solar Energy functions at night.

Can my roof have solar panels? 

Not all roofs are ideal for solar. It might be great for solar if your roof area faces south, east, or west and isn't shadowed. Solar won't work if you have trees that completely shade your roof and you're not prepared to chop or remove the trees. Check out the full guide for more great facts about solar energy.

Does a solar photovoltaic system produce the same energy during the day?

Your solar system awakens typically at around 6 am and goes to sleep at around 6 or 7 pm since solar PV depends on how much sunlight it receives to function. The energy production progressively rises, reaches a peak at noon, and then begins to decline as the sun begins to set. However, since the solar energy produced is integrated with either your batteries or your existing electrical connection, the operation of your electrical devices is not hampered. And all of your electrical appliances are completely safe if your solar PV system is designed correctly. Check out the full guide for more info.
