13 advantages of solar energy: Why it’s worth the switch

From business leaders and environmentalists to governments across the country, everyone is talking about the advantages of solar energy, especially in India. And for all the right reasons. Solar energy is inexhaustible and renewable, helps boost property value, gains green credits for businesses, and offers electricity almost free of cost.

Here are some major advantages of solar energy you can’t miss:

1.  Renewable and abundant

One of the biggest advantages of solar energy is that it is a renewable resource. Since sun is an inexhaustible source of power, we can receive solar energy for centuries to come. Unlike coal, gas, or fossil fuels which take years to produce and are prone to getting exhausted in the near future, solar energy can be the ultimate solution for India’s growing energy needs.

Not only is solar energy renewable, it is also fairly abundant. As per the Energy Efficiency & Renewable Energy Management Centre, India has about 300-330 sunny days, meaning there is enough to power homes, businesses, organizations, and institutions year-round.

2.  No harmful emissions

Every unit of energy generated from conventional sources releases harmful gases like carbon dioxide and other greenhouse gases. Solar energy, on the other hand, causes no such emissions, and is a completely safe mode of power for humans, animals, and nature. Solar use prevents the air quality from deteriorating and offsets tons of carbon emissions to support healthier communities.

3. Helps conserve water

Traditional power generation in thermal power plants requires large amounts of water to keep the machines cool. This high temperature water is discharged back into neighboring water bodies, disturbing the natural fauna and flora, and causing pollution.

Solar energy generation requires no water. This becomes an important solar energy advantage because India, like the rest of the world, faces acute water shortage. Solar energy is therefore an environmentally responsible choice for rural as well as urban installations.

4. Reduced load on fossil fuels and energy systems

When homes and businesses generate their own electricity via rooftop solar systems, it lowers grid demand. This ensures that the national grid becomes more stable and resilient.

Reduced reliance on conventional energy further lessens the impact on thermal power systems.

5. Long-term savings

The most popular of the advantages of solar energy has to be reduced electricity bills and long-term savings. When you install a solar setup, you generate your own electricity. This means no more worrying about ACs and heaters stacking up your bills year-round.

When electricity is free each month, savings can be substantial. Moreover, having solar energy at your home can make you immune to tariff hikes or price fluctuations. For businesses, solar energy use can significantly reduce operating expenses.

For instance, this family-owned business in Gujarat is now saving almost ₹48 lakhs every year with the simple switch to solar. Witness their solar success story in action:

If the initial installation costs make you hesitant, it’s worth noting that most solar setups recover their costs in just a matter of 4-6 years.

6. Energy independence

By generating electricity on your own, you not only enjoy energy independence, but also become immune to load shedding, power shortages, and fluctuations during demand surge.

Worried about non-peak hours when the sun isn’t out? Solar panel systems now come equipped with battery storage systems that store excess energy for later use.

7. Low maintenance costs and minimal upkeep

If you’re worried about maintaining a huge solar setup, consider this: solar panels are very low maintenance. With regular cleaning and periodic inspections, you can keep them up and running for up to 30 years.

For a smooth journey, a lot of residential users turn to AMCs from trusted providers, while businesses utilize specialized operations and maintenance (O&M) services for regular upkeep.

Tata Power, for instance, offers end-to-end solar O&M services that include preventive maintenance, performance monitoring, and expert technical support, helping customers maximize energy output and extend the life of their solar systems.

8. Noise-free power generation

One of the lesser-known advantages of solar panels is that they don’t produce any noise during operation. Silent operation improves comfort at home and creates a better working environment in commercial spaces. It also makes solar a great option for locations where noise restrictions apply or where peace and quiet are important.

Diesel generators and thermal power plants, by contrast, create a lot of unnecessary sound, making them unfit for use in schools, hospitals, residential areas, etc.

9. Accessible even in remote areas

Did you know, solar energy can reach areas even conventional energy can’t? When traditional grids and wires can prove expensive, even inaccessible, to hilly areas, remote villages, and islands, solar energy becomes the solution. Rooftop systems, solar mini-grids, and hybrid installations become useful for lighting up homes, schools, hospitals and dispensaries, farms, and small businesses.

Different solar setups include:

Developed by Tata Power, Kayamkulam, Kerala’s floating solar plant sits on a water body, and supplies electricity to the Kerala State Electricity Board (KSEB). This 101.6 MW plant offsets over 64,000 tons of carbon emissions every year while making efficient use of 350 acres of previously unutilized space.

10. Flexible for every need

If you think solar energy is just about setting up rows of solar panels on big roof spaces, think again. Solar energy offers a wide range of applications that can be customized and altered for every need. From large-scale solar power plants for industries to compact solar systems for MSMEs, solar is built for all. Looking for a small setup at home? 1-3 kW systems can be easily installed on balconies and windows to power your apartment smoothly.

Tata Power is using advanced solar technology to come up with flexible solar solutions that fit different spaces, budgets, and energy needs: limited spaces like villas, schools, and residential societies can utilize solar trees, and solar carports offer dual benefits in offices. While farmers can enjoy the ground-mounted solar panels for agrivoltaics, battery-based solar systems ensure that you always have energy backup.

Now that you’ve seen what’s possible, the next step is bringing solar into your own space.

11.  Scalable for your growing needs

Most solar solutions are modular by design, meaning they are easy to upsize when your energy demand grows. Imagine you start with a small setup for your home, just to power basic appliances. Overtime, you might add a water heater, an air conditioner, or even an electric vehicle.

Similarly for businesses, one might need energy for limited operations early on. But as business grows and energy demands skyrocket, you will need a bigger system. Thanks to the scalability of solar, you don’t have to switch up your old system. You can simply get in touch with your solar provider to expand capacity in phases, keeping costs manageable and ensuring an interrupted supply.

12. Trade and earn credits

When it comes to businesses, one of the most financially rewarding advantages of solar energy is earning Renewable Energy Certificates. For every 1 MWh of clean energy, you can earn one REC. Companies and utilities require RECs to meet their renewable energy obligations. So not only are you environmentally compliant, you can also sell the extra RECs.

13. Generates employment and strengthens communities

Solar energy isn’t just about clean energy, it is also a catalyst of growth. From solar panels in apartments to large-scale utility projects, every new solar project creates employment. From manufacturing and transporting modules, to installing and monitoring the system, each step involves professional support from skilled and semi-skilled workers. In remote or rural areas with dearth of opportunities, one project can stir economic activity for many.

Additionally, when electricity reaches a remote region, people gain access to education, healthcare, and improved living standards. Solar energy use then contributes to community development, improves infrastructure, and enhances the overall quality of life.

Solar energy offers an array of environmental, financial, and social benefits. It helps reduce carbon emissions, conserve resources, lower electricity bills, and bring reliable power to homes, businesses, and communities. Its flexibility, scalability, and low maintenance make it a practical solution for all, while also supporting local employment and contributing to a sustainable future. With solar, every step toward clean energy creates a positive impact for your energy needs, your wallet, and the planet.
