Solar energy is one of the renewable energy sources we have never had before. There are some pros and cons about it. Although there are some cons about the solar energy, I believe that the pros of the solar energy are more than the cons.

Solar energy generation is a new technology which absorbs the radiation from the sun and reproduce the heat to generate electricity.

There are lots of advantages and disadvantages for the newly developed energy - solar energy. I try to explore them below.

The solar energy is fully green and is environmentally friendly once the system is installed. It means that there is no way the environment is polluted after installation of the facilities, “The power generated from solar does not pollute the environment or release greenhouse effects Solar power doesn’t release any greenhouse gasses, and except for needing a source of clean water to function “because the solar energy’s source is from the sun, and absorbing the suns energy wont pollute the environment.

The economic advantage of solar energy is that the cost of solar panels decreased in 2016 and 2017 before the solar panels are only used for business and government facilities. With the government support and price drop, more people could afford it. The driving forces of solar energy development just come from the government. For example, the US government provided incentives to the solar industry. In 2010, approximately, $968 billion dollars were used to subsidize the industry. Now some best solar panels are mostly cheaper than purchasing electricity from utility company.

The standard way to evaluate solar panels system cost is cost-per-watt or dollars-per-watt. It is calculated be the total cost of installation system (parts and labour) and it is divided by how much power it generates (electrical output). In 2019 it is estimated that cost-per-watt in California ranges from $4.39 for a small system and down to$3.56 for a large one. Now the installing cost of solar panels is estimated between $7-$9 per watt. Let’s take an example here. A system which costs $18000 has a payback period of about 20 years. The cost of a solar panels today is around $3 per watt and the extra cost of installation increase the cost up to $5-$6 per watt. Homeowners who are interested in solar roofs should bear the idea in mind that solar system are more expensive than traditional roof installation.

Disadvantages; Although the solar energy won’t cost any environmental damage to the environment, the solar panels used to produce power still have the chances to pollute the environment. The energy producing process require lots of material and some are very harmful to the environment. Producing solar grade silicon process may be involved in producing dangerous chemicals. These chemicals may not be properly disposed, depending on the solar panel manufactures. It may cost more energy to produce it than other form of energy generation, depending on the quality of solar panels. “To produce solar-grade silicon, semi-conductors processing typically involves hazardous chemicals. Depending on the solar panel manufacturer, these chemicals may or may not be disposed properly.” Also it will cose more energy for producing solar energy” The manufacturing of solar panels requires more energy up front to produce than other forms of energy generation.”

The economic disadvantage of solar energy is that when people buy solar panels, they may buy those with lower quality but pay high prices for it. People would pay more to fix it and probably buy a new one to replace it because it is easily broken. It is a fact that there are various solar panels with varying levels of efficiency, durability, reliability and designs available in the market

Some people doubt the benefit of solar energy. To make sure whether the solar energy is good or not for humans and the environment, we can try to install solar panels on our roofs to test it. This is a safe and easy way to demonstrate that we care about the environment.

Conclusion:

From the descriptions and examples, I have just given, I think that the solar power has more advantages than disadvantages for the reason that the new power undoubtedly bring us clean and more environment friendly surroundings. In my opinion, the most advantage is that this solar energy is a new energy resource, recently innovated power which compensates the of global energy shortage we have encountered for many years. In addition, the cost of solar power generation has been substantially reduced recently years due to the subsidies of the government. And it is believed that it will keep reducing in the future and we are all benefited from the new source of energy.
