What Are The Pros And Cons Of Solar Energy

In our continuing efforts to live a greener life we have been contemplating solar panels for our roof. Solar energy is one of the main sources of renewable energy. Apart from being free, its abundance and constant supply make it a great potential source of energy. Solar energy can be used for electricity, central heating, hot water, cooking, for producing salt and even for desalination.

Advantages of Solar Energy :

1 . It is renewable, clean energy and does not deplete any of Earth's resources

2 . It reduces greenhouse gas,cuts down on acid rain and omits no pollution

3 . No noise is created with solar power, unlike wind power, hydro and coal-fired electric plants

4 . Solar energy can be very efficient energy resource in a large area of the earth

5 . Solar power system require virtually no maintenance and can last for decades

6 . Solar energy systems are portable and adaptable

7 . Reduces the amount of fossil fuel burnt, and decreases greenhouse gas creation

Solar energy is less expensive than electric heating. That is another big advantage of solar energy. By just using solar energy you can save a lot of money on heaters. In return you will get lower electric bills and it also means that you don’t have to maintain heaters.

Disadvantages of Solar Energy :

1 . The biggest disadvantage of solar energy is the initial cost of solar cells. Some households may need more than one to generate enough power, making the initial installation of solar panels very costly

2 . Solar energy can only be used to generate electricity during daylight hours. This means that solar panels will not be producing energy for your home for one half of the day

3 . Need for a fair amount of sunlight to create enough energy

4 . In heavily polluted areas the amount of energy created by the sun will be reduced

5 . The weather can affect the productivity of solar cells

I truly believe that the world needs to make a large push to using renewable energy such as solar panels or wind turbines if we are going to be able to make our resources last.
