What are the advantages and disadvantages of solar energy?

As the name suggests, solar energy derives its energy from the sun. It is the creation of energy through the heat and light generated from the sun. This energy, because it takes the form of solar radiation it can be used in the production of electricity which is harnessed with the used of solar panels which is carefully provided by solar panels Melbourne.

The amount of energy produced by the sun in a single day can be used to meet the world’s need for energy in a year. Despite the virtue the sun provides, we have failed to put it to adequate use.

Although the reason for the unpopular wide adoption of social energy is based on the claim that it is quite expensive and inefficient. However, since becoming a household name, companies have delved into studies to provide the best ways through which solar energy can be efficiently transformed into electricity and other usages.


1.     Solar Energy is Renewable 

Among other sources of energy, solar energy remains the most renewable. This is the most important feature of the solar energy. It can be put to use in any part of the world on a daily basis with any fear of it finishing. As long as the sun remains, there is a guarantee that the solar energy would remain a reason being that the sun is its source.

2.     It Reduces Cost 

The cost of providing electricity to homes across the world has become very expensive. However, with the implementation of the solar energy in the provision of electricity, the cost is reduced to the barest minimum. More so, one can get extra money by exporting excess back to the grid if your panel is connected to the grid.

3.     Various Use cases 

Known as the power of the people, solar energy does more than generating heat and light. It can be used to provide electricity in areas that lack grids, for the provision of clean water. Satellites in space can also be powered by solar energy. Recently, a company in Japan called Sharp invented a transparent window powered by solar energy.

4.     Minimal cost for maintenance

There is little maintenance need for solar panels as all that is needed is that they are kept clean. Cleaning can be some few times in a year. The part that might demand maintenance is the inverter itself and that’s usually after five to ten years due to its constant work rate to provide electricity from solar energy. The wiring might also need to be changed after sometimes. However, upon the initial cost, there is just a little money to spend on maintenance over the years.

5.     It is climate-friendly 

Adopting the use of solar energy does not come with so much an issue of pollution as seen in other sources of energy. The amount of pollution associated with the solar energy as regards transporting, manufacturing and installing solar related systems cannot be compared with other sources. Since the adoption of solar energy would bring a stall to the usage of other sources of energy, issues affecting climate would be reduced.

6.     Development of Technology 

There is a lot of improvement and advancement in the technology industry due to the solar energy. Nanotechnology and quantum physics offers new technological systems that can bring out the best in solar panels and powers systems.


1.     Expensive 

Purchasing and installing solar systems is very expensive. Despite the part intervention of some government, the price to be paid by homeowners is still on the high. There are claims that the prices would go down over time as it is still very expensive due to its novelty.

2.     Its functionality depends on the weather 

The solar system depends largely on sunshine. In times, like winter, where there is hardly sun, the solar system is not as effective as it should be. More so, it cannot acquire energy at night except if thermodynamic panels are employed.

3.     Storage systems are costly 

To enjoy all day long usage, solar energies can be stored in batteries. However, acquiring these batteries could be quite expensive considering the number of batteries to be used.

4.     Requires large space 

To produce more electricity, there would be the need for more solar panels to receive as much energy from the sun as possible. These panels demand space and if you do not have that amount of space, your energy needs would be met by depending on the grid.

In all, solar energy has its good and bad sides but it is certain that with time, solutions would be provided for its shortcomings, making life an easier and better place to live.
