Advantages and disadvantages of solar energy

There are a number of purposes that solar energy is used for these days. These include electricity generation for homes and offices, solar heating, cooking, desalination of water and many more.. Solar energy is one of the most eco-friendly energy sources known to mankind because it does not produce any pollutants hence does not harm the atmosphere and environment of the planet. It is a fact that the Sun is very, very far away from the Earth, and this means that the radiations of the Sun are weakened considerably by the time they reach the Earth. Following are some of the advantages and disadvantages associated to the use of solar energy for power generation through solar panels.

Advantages of solar energy:

Solar energy is a naturally pure of energy generation:

The greatest advantage of using solar energy is the fact that it is completely pure. It does not require any amalgamation and the rays of the sun can directly be utilized to generate electricity. This means that the process of power production with the help of solar energy does not affect the natural resources of our planet, which are steadily depleting due to excessive usage. All solar power generation requires are solar panels which can receive energy from the sun and convert it to electricity. Plus there are no emissions or side effects related to the use of solar panels at all.

Solar panels provide cheap electricity:

Another great advantage is fact that power production with the help of solar energy is the cheapest way of generating electricity known to mankind. The installation of solar panels in your home or office depends entirely upon your own requirement. Usually solar panel installation is the only initial investment that is required, which eventually pays back in the long run. Once your solar panels have been installed, you can say good bye to all electricity energy related utility bills for a long, long time! You can save every penny that was previously being spent on paying bills for heating, cooking and electricity consumption purposes.

Solar panels don’t require grid stations:

Solar energy is a great alternative when it comes to providing electricity to houses built in remote areas and villages. These houses usually do not have electric supply from the local companies because there are no power plants or grid stations in the area. The most ideal way of generating electricity for these isolated home is by the installation of several solar panels on the roofs of the houses. This energy can be used to power the whole house and one would not require local electricity supply companies at all.

Solar energy can be used for the desalinization of water:

With more studies and exploration into solar energy application, another amazing use has been put forward. Solar energy can now be used to provide clean and safe drinking water to areas where this utility is not available. Solar energy is used to evaporate brine from water, leaving it pure and fit for human consumption.

Solar panels can power industries:

One of the biggest advantages of solar panels is that they don’t require any wiring or grid stations at all, as previously discussed. This is the reason that industries and even factories that are located in deserted places can be powered exclusively by solar panels. Factories and industries are the biggest contributors to world pollution, and if they are powered by solar energy, they will not be releasing the dreaded carbon emissions that are contributing to global warming. Industrial processes like distillation, sterilization, space heating and space cooling can all take place with the help of solar energy.

Disadvantages of solar energy:

Cost of solar panels

The biggest disadvantage associated with the use of solar energy is the fact that the rays of the Sun by the time they reach the Earth are significantly weak and dilute. Therefore, in order to produce a significant amount of electricity or for heating purposes more solar collectors and panels are needed in the house. Solar energy allows you to save considerably on your utility bills, but for many the initial investment is of great concern because the installation of these solar panels can be rather expensive. Solar energy does eventually pay back on the initial investment, which is a fact but then again generating enough capital to purchase and install solar panels makes many people hesitant.

Solar panels need ample sunlight to work:

Another great disadvantage is the fact that electricity generation can only take place if the region where you are situated receives ample sunlight all year round. If you live in a part of the world that gets sunlight all year round, solar energy can easily be used to produce electricity. Solar power panels are ineffective in places with frequently cloudy weather and perpetual darkness for several months.


Even though there are a few disadvantages of installing solar panels, the advantages far outweigh them. Not only will you be able to generate emission free, environmentally friendly electricity through solar panels most of the time, but you will also be able to have energy independence which is a very important investment in your own future.
