10 interesting facts about solar energy


The sun has great potential to power our civilization in a safe and reliable manner because it is the most abundant clean source of energy on the planet. The sun's radiant energy may power homes, companies, and even cars when it is transformed into heat and electricity. With all this, it would be foolish not to take advantage of this free energy. The moment may be right for you to discover the benefits of solar energy and consider installing a solar energy system in your house.


#1 The planet's most plentiful source of energy

The sun is the most vast source of energy. The demands of humanity on Earth for an entire year can be satisfied by just one hour of solar energy striking the planet's surface. It emits heat and light, also known as solar energy, which enables life to exist on Earth.


#2 Fastest way to deploy energy

Solar power is one of the convenient and fastest way to deploy. The capacity of solar power, or the quantity of electricity it can produce from energy it gathers, is expanding quickly as the technology has made panels more efficient in the recent years. Also given the modular and scalable nature of the technology, it is possible to build mega projects as well as solutions for a small home.


#3 Over a decade, the cost of energy exploitation has fallen

The relative cost is what is considered while deciding what kind of power plants to build. Also known as levelized cost of electricity (LCOE) which is the average cost in currency per energy unit, was the lowest for solar PV in India in 2021.


#4 Solar Panels have long life

Solar panels can last up to 25 years and continue to perform after that but their efficiency may go down. These power plants have a long lifespan since panels are simple to replace and can be updated with new, more efficient modules for comparatively little money.



#5 Over the course of a solar panel's life, very little greenhouse gas is produced

While the process of producing solar energy doesn't release any greenhouse gases, other phases of the life cycle do, albeit in small amounts. This includes production of solar cells and panels, as well as their transportation, installation, upkeep, decommissioning, and dismantling.


#6 2020 saw the lowest cost of electricity ever thanks to solar power

According to a 2020 report by the International Renewable Energy Agency (IRENA), Solar energy is currently the most affordable source of electricity ever. Solar energy is also more affordable than coal and gas in the majority of developed nations.


#7 China has the highest solar energy production

China has astounding solar power. The nation is the world's largest producer of solar energy with a massive 392 GW installation. The country installed more than 30.88 GW of solar PV systems in the first half of 2022.


#8 Solar technology is becoming increasingly effective

Less than 2% of the world's energy as of 2018 came from solar. Solar energy harvesting has typically been expensive and ineffective. The cost-cutting effects of new technology innovations over the past 20 years have fuelled this rising reliance on solar energy, and future technological advancements promise to support this usage by further reducing costs and improving solar panel efficiency.


#9 India wants to lead the world in producing solar energy

Over the past ten years, India has become a global leader in the production of solar energy, having taken considerable measures to enhance its capacity and experience in the field. India stands 4th in solar PV deployment across the globe as of the end of 2021.


#10 Solar energy has little negative effects on the environment

While using solar energy to produce electricity does not contribute to global warming, other phases of the solar life cycle, such as manufacturing, transporting materials, and decommissioning and dismantling, do emit some harmful chemicals in the environment. These are however negligible as compared to burning of fossil fuels for power generation and can be tackled with advances in technology, regulations and policies.
