What is Solar Energy? How it Works, Benefits & Challenges
In a time when there are rising climate concerns and the need for conserving fossil fuels, solar energy has emerged as a beacon of hope.
Across the world, solar energy is emerging as a leading source of clean energy and a great alternative to fossil fuels. From bustling metropolises to remote villages, the sun's immense and renewable energy is being used to power homes, industries, and companies in India - catalysing a remarkable shift from fossil fuels.
In this article, we will explore the concept of solar power and delve into its significance. We will highlight the challenges and future of solar energy in India.
Understanding What is Solar Energy and How Does It Work?
Solar energy is thermal or electrical energy harvested from sunlight.
The process of converting solar energy starts with the absorption of sunlight by solar panels. These panels of semiconductor materials absorb particles from the sun, called photons.
When photons penetrate the panel, they excite the electrons from the atoms of these materials. This excitation creates an electric current that powers homes, industries, and even entire communities.
Solar energy can be integrated into daily life through the smart integration of power grids and inverters, offering a sustainable and reliable source of electricity.
What's more, the electricity created from solar panels can be stored in batteries. This way, you can use it later on. As such, you secure a continuous supply of clean energy even at night or on rainy days. This storage capability further enhances the reliability of solar power systems. It makes them a viable solution for both urban and remote areas.
Top 5 Benefits of Solar Energy: Brightening the Path Towards a Better Future
Solar power has many benefits for the environment, communities, and individuals. By harnessing the sun's power, solar energy helps unlock a future free of carbon emissions and pollution.
It allows us to conserve fossil fuels that are in danger of getting exhausted, leaving nothing for future generations. Here's a more detailed look into the benefits of solar energy:
1. Preserving Ecosystem and Reducing Pollution
Solar energy scores high marks when it comes to preserving the environment. Unlike fossil fuels, it does not release greenhouse gases harmful to the environment. It also doesn't contribute to air pollution.
Besides that, its positive impact on air quality helps to combat water issues. Traditional power plants need significant amounts of water for cooling purposes. This places immense pressure on an already limited amount of water resources.
In contrast, generating solar energy needs minimal water usage. This makes it a great choice in particular regions that face water scarcity.
2. Preserves The Ecosystem
One of the most compelling benefits of solar energy is its potential to safeguard biodiversity. Solar installations have a smaller environmental impact than traditional sources of energy that are often responsible for habitat loss.
Solar farms can be built on marginal lands, minimising the need to disrupt lands and biodiversity. Moreover, no pollution is created during their operation. This means nearby ecosystems remain unspoiled, contributing to the protection of species and delicate habitats.
3. Bringing Light to Underprivileged Population
It may seem trivial, but the fact that every area of the Earth gets sunlight to a lesser or greater extent offers a strong advantage. Sunlight is an energy source that can get to places without reliable electricity. This often includes isolated village areas.
By deploying solar PV modules and water heaters, communities can access hot water and electricity without relying on conventional energy sources. This helps improve the quality of their life and opens the door to better healthcare, education, and economic development.
It is also available as community-owned solar projects, solar-powered appliances, and mini-grids. This will help communities to take charge of their energy needs, fostering a sense of self-reliance.
4. Lower Energy Cost and Less Maintenance
You're no longer purchasing electricity from the grid when using solar energy. This translates to savings on your energy bills. With rising power prices, consumers can save a considerable amount on electricity bills by opting for solar power.
What's more, India's power grid is suspectable to regular power cuts and voltage fluctuations. Investing in solar battery systems can maintain an uninterrupted power supply even during blackouts. This way, your work doesn't get disrupted, and you don't have to wait for electricity to come back to get back to your task.
Once installed, a solar system requires less maintenance as long as environmental factors do not harm it. If you keep the panels clean and debris-free, they will function well for many years.
5. Leveraging Government Incentives
The Indian Government has been supporting solar power through various initiatives and incentives. They offer tax benefits for industrial and commercial solar systems. Additionally, companies can claim accelerated depreciation on solar power systems. This helps to reduce their tax liability.
Challenges to Harnessing the Power of Solar Energy
The Government even provides net metering policies. This enables businesses to sell excessive electricity generated from solar systems back to the grid.
While energy generated from the sun serves as a boon for the energy sector, many challenges still limit India from realising its full potential.
There is a lack of R&D, manufacturing infrastructure, and development facilities in the country. This impacts the development of solar panels, inverters, and equipment to meet the demand. Plus, solar systems still demand significant investments in the beginning. Also, they have extended payback periods.
Besides that, a lack of awareness amongst the public about solar energy is slowing down its adoption. People, especially in rural areas, need to learn about the benefits and potential of solar power.
Another major challenge is the scarcity of land to put large-scale solar systems in place. Some issues like government approvals and financial restraints are affecting the setup of solar generation plants. Plus, there is also a lack of resources to manage solar waste.
The government needs to make strategic decisions to address these challenges. The country can increase its solar energy generation by establishing dedicated government bodies and supportive policies. India can also address these barriers through public-private partnerships and innovative financing models. This will, in the end, make solar power more affordable and accessible for all.
What is the Future of Solar Energy in India: Towards a Brighter & Sustainable Future
India is one of the nations standing at the forefront of solar energy adoption. The country has abundant solar power capable of generating 5,000 trillion KW of clean energy. Additionally, India has around 300 sunny days in most parts and solar insolation of around 4-7 kWh per square meter each day.
If harnessed in an efficient way, this energy can reduce our dependence on fossil fuels. Plus, it can lower the carbon emissions related to energy generation. It will even help minimise the energy demand gap across the country.
The good news is that solar energy businesses have undertaken large projects in India in the past years to enhance the generation of solar power. The country's solar capacity has seen a massive transformation, enhancing from 21,651 MW to 70,096 MW in 2023[1]. With policies like the Production Linked Incentive (PLI), India is moving ahead to achieve by 2030 around 500 GW of renewable energy capacity.
The potential future of solar energy in India looks promising as the price of solar energy has also started to come down. Besides that, the government initiatives and programmes reflect a commitment to solar power and a sustainable future.
