Photovoltaic Solar Energy Advantages and Disadvantages

Photovoltaic solar energy is a renewable resource that year after year becomes increasingly popular as technology chosen to generate electricity

Photovoltaic Solar Energy Advantages and Disadvantages: 10 advantages and 6 disadvantages

1 # The production cost is lower. Many users see in this sustainable energy, a way to substantially reduce their electricity bill. This is undoubtedly one of the main advantages, not to mention the main one. It will be cheaper for us.

2 # In some countries there are subsidies . At the beginning, when it began to be implemented, succulent grants were offered to bet on this initiative. At the end of the day, with time it is very advantageous. There are fewer and fewer grants for this purpose, but you can consult it in your country of origin.

3 # Contribute to the environment . It is a “healthy” energy for the ecosystem. It does not cause pollution but it is true that leftovers are filtered during transport or installation of the power panels, however it is very little compared to conventional energy sources. This movement also helps to fight against climate change.

4 # Global availability . The sun shines in all corners of the world, therefore, if there is sun, there is solar energy to a greater or lesser extent.

5 # Maintenance is cheap . The maintenance of the solar panels is really low. If you want to install it in your house, it is possible that one cleaning per year is enough. It could require even two, but no more. The panels or solar tubes also have a guarantee of about 25 years, making this type of products the best long-term alternative.

6 # You can generate electricity at remote sites . Without a doubt one of the advantages is that it can be used to have electricity in places that can not depend on electrical networks. You just have to install the panels to enjoy this type of energy.

7 # Transparent panels in the future . One of the bets that have already been implemented in places like Japan, are windows with integrated transparent solar panels. In such a way, that the user will not have to do anything after buying them. Simply, the corresponding annual cleanings.

8 # It is a sustainable energy . This is another of the great advantages, like  our solar skylight , it does not consume itself.

9 # It is a renewable source . Even if we wanted, we could not remain without solar energy because it is renewable. It is another of the most outstanding advantages.

10 # You can sell the energy that you over . Many individuals can sell the excess energy produced. You have to read the regulations well.

These are the advantages we could highlight about using solar energy, but not everything that glitters is gold, we also want you to know the small defects that we have to have when choosing our preferred energy.

6 disadvantages of solar energy

As you can see, there are fewer disadvantages than advantages. But although everything seemed very nice, these  6 disadvantages of solar energy  may make you reconsider the installation of any energy-gathering device:

1 # Requires a normally high economic investment . Really, solar energy is expensive, when panels are installed, many times half of the project is being subsidized, therefore, it is difficult to foresee the real cost of the investment. It is the main reason why many users think twice. In the short term, it is expensive, but over time, apart from contributing to the environment, the savings will of course be substantial and notable.

2 # You will need to do works at home . This is also associated with the costs since you will have to install the solar panels

3 # You will not always have the energy you want . Solar energy depends on the sun, if there is not, we will have less energy. We can enjoy more or less energy, but in general, it should reach us without problems even if the day is cloudy. Unfortunately, we can not predict the energy that will be produced each day.

4 # Contaminates a little . The installation of solar panels and transport causes an impact on the atmosphere. Nonetheless, it is a clean energy. Contaminates very little, that’s why it contributes to the environment.

5 # Beware of space . The lower the solar power density (W / m ^ 2), the more space we need, which implies higher costs. Storing energy is expensive, as well as batteries to calm the production-demand of energy.

6 # The panels are not totally efficient. At this time, there is still a long way to go for solar energy. The panels do not manage to be as efficient as they should be. Some are also limited to certain areas.


It is an excellent alternative to cover and complement the energy needs of small cities or homes, to this day it is impractical when using this technology as the main energy source of the home, but it is a great option to use as complement.

If you are a person committed to the environment, this type of renewable energy is undoubtedly the best option to take care of the environment. It is renewable and does not harm the environment.
