Solar energy is the energy from the sun that is converted into thermal or electrical energy. Sun is a source of unlimited supply of energy and this is the cleanest and most abundant form of energy available on the earth.
While a majority of the world’s current electricity supply is generated from fossil fuels such as coal, oil and natural gas, these traditional energy sources face a number of challenges including rising prices, security concerns over dependence on imports from a limited number of countries which have significant fossil fuel supplies, and growing environmental concerns over the climate change risks associated with power generation using fossil fuels. As a result of these and other challenges facing traditional energy sources, governments, businesses and consumers are increasingly supporting the development of alternative energy sources and new technologies for electricity generation.
Assume you have a 1 kWh rooftop system. A 1 kWh system will cost you around 80,000 rupees. A solar PV system’s lifecycle usually lasts 25 years so your system shall cost you about 3,200 rupees per year. Now, 1 kWh system shall produce about 4.5 units of power everyday. Considering the price of grid electricity to be 4 rupees, you earn about 6,570 rupees every year. That is 3,370 rupees of savings every year!
- It’s free.
Solar-energy systems allow you to capture free sunlight and convert it into usable power in your home.
- It’s clean.
Solar energy can be used to heat and cool your home, but it has almost no impact on the global climate. By comparison, electricity generated by power plants produces carbon dioxide emissions that scientists say pose serious threats to the environment.
- It’s infinitely renewable.
While nonrenewable energy sources like oil, gas and coal are becoming increasingly scarce, the sun’s energy is limitless. Wherever sunlight shines, electricity can be generated.
- It can reduce your utility costs.
Having a system that creates solar energy means you use less electricity from your utility company and that can contribute to lower heating and cooling costs. To find out how much you can save by harnessing energy from the sun, use our solar calculator.
- It comes with incentives.
The Government of India and some states provide tax benefits for renewable-energy systems. Depending on where you live, you may also be eligible for incentives through your utility company.
- It increases your energy self-reliance.
The more sunlight harnessed by the system, the less electricity you need from your utility supplier.
- It’s extremely reliable.
The sun has been around for billions of years and is likely to burn on for billions more to come. And when you consider how a trusted name like Lennox is putting it to economical use in the home, it’s easy to see solar energy’s future is bright.
