Advantages & disadvantages of Solar Energy

Energy produced from sunlight is called solar energy and sun is the primary source of energy on earth. Sunlight is available to all and therefore, this is the preferred substitute for non-renewable types of energy.  Using up non-renewable sources of energy like coal and fossil fuels will pollute the environment, raise the global temperature and cause widespread diseases and disorders. It’s time we look for alternatives to non-renewable sources of energy before their stock runs out. Solar energy is the most popular alternative available to us. But even this type of energy has its share of pros and cons. Following points discuss the advantages and disadvantages of solar energy.


  1. Renewable Energy: The biggest advantage is that it’s unlimited in quantity. Sunlight is available to all parts of the world and producing energy from it will be very beneficial. This energy will be accessible as long as the sun is present.
  2. Pocket-friendly in long-term: The appliances using solar energy are one time investments. They will not charge you after installation so forget the electricity bills. By connecting the solar panels to the grid, you can earn money by selling the excess energy generated. The maintenance of solar appliances is also very cheap.
  3. Diverse Applications: Many solar energy compatible products are available. New technologies are being invented every day to incorporate solar energy on almost all electrical appliances. Cookers, air conditioners, phone chargers and even trains use solar energy for continuous energy usage.
  4. Less Pollution: Usage of solar energy will reduce pollution levels drastically. Solar energy is produced silently so zero noise pollution. Its utility prevents various other pollutions.
  5. Future of Technology: The world will soon move to renewable sources of energy and solar energy will have the most number of applications. A lot of houses in some countries have adopted solar energy and are reaping the benefits.


  1. Initially Expensive: Installing solar panels and various solar appliances are the batteries, inverters and the installation charge all ramp up the cost of merely the setting up.
  2. Dependent on Weather: Solar energy cannot be produced during the rainy season or in winters when the intensity of sunlight is very low. This becomes an issue in places where electricity is needed and then one has to turn to non-renewable sources of energy.
  3. Takes up Space: Installing solar panels and its accessories take up a lot of space. Some roofs may not be big enough to install the required number of solar panels and so people will have to adjust.
  4. Effectiveness: Highly polluted areas will not produce the required amount of solar energy. Developing countries with alarming levels of pollution are not ready for the switch to this source of energy.
  5. Power produced only in days: Without the sun, there will be no solar energy. Therefore, solar energy will be produced only in days. The rate of production will be high in the morning and low in the evening.


Solar energy will be the best answer for our daily electrical needs in the future. Tackling the cons of solar energy and its successful adoption is important. Education regarding it is necessary and government intervention for reforms in this matter is also recommended.
