Solar energy for the home: advantages and disadvantages


Before making the decision to change the electrical energy for solar panels, it is important to gather as much information as possible to know if it is a viable alternative for us. Learn in this article the main advantages and disadvantages of solar energy at home.

Installing solar panels at home is an environmentally responsible decision. It is a long-term investment, because although at first it may be a little expensive to access this alternative, over time the electricity bills will be reduced and commercial value will be added to the property.

Before delving into the advantages and disadvantages of solar energy in the home, it is important to know what it is. This type of renewable energy has grown in popularity in recent years, due to its great contributions to the care of the environment.

What is solar energy?

Solar energy, as its name suggests, is obtained from the sun and its direct radiation on the Earth. It can be used to generate electricity and heat for all kinds of uses.

Although it is a type of renewable and sustainable energy, it is not free of pollutants that can harm the environment. However, it is one of the cleanest forms of energy.

How many types of solar energy are there?

Knowing how to correctly differentiate the types of solar energy will help us to define the most recommendable for us. According to how it is obtained, it can be classified into 3 classes:

  • Photovoltaic: this is the most common and is characterized by transforming the sun’s rays into energy through the use of panels or cells. Silicon is the main material used in solar panels. This element, when excited by sunlight, causes electrons to move freely, generating an electric current.
  • Photothermal: Unlike photovoltaic, which uses the sun’s energy to transform it into electricity, photothermal absorbs radiation in water tanks and transforms it into heat, which is used to heat fluids for heating.
  • Thermoelectric: transforms solar energy into electricity indirectly, using photothermal energy to increase the temperature of a fluid until it evaporates. This steam activates a turbine that begins to rotate and generate kinetic energy. The turbine is connected to a generator and the motion produces electricity.

Advantages of solar energy

Solar panels are a great ecological alternative when we want to consume our own energy and reduce future bill costs. Its benefits are multiple and it is worth knowing them if we are thinking of making the investment.

It is a clean energy

The main attraction of solar energy, unlike other sources, is that it does not generate any polluting emissions that may affect the environment. Once the solar panels are installed, there will be no emission of greenhouse gases, for example.

What does pollute is the manufacturing process of the panels. We will see that later.

Economic and energy savings

It is true that the purchase of solar panels can be expensive at the beginning. However, over time this investment pays off in lower bills and the possibility of reselling the energy that is not consumed through bi-directional meters.

Available worldwide

As long as the sun shines in the Milky Way, there will be solar energy that we can take advantage of on our planet. One of its greatest advantages is that we can use it all over the world, to a greater or lesser extent.

In addition, it is a good alternative for those remote sites that cannot rely on electricity grids due to their location. It is only a matter of investing in the acquisition of solar panels and that’s it, ecosystem-friendly energy anywhere!

No noise pollution

Nobody likes the annoying and unnecessary noise that can be caused by electric grids. Unlike conventional generators, solar panels do not produce any external noise.

They are economical to maintain

Once the initial investment has been made, only one or two cleanings per year are needed to keep the panels in good condition. In addition, most of them have a 25-year warranty, making them a good long-term alternative.

Disadvantages of using solar energy

It is clear that the pros far outweigh the possible disadvantages. However, here are 5 disadvantages of using solar panels in our homes.

Investment and installation are expensive

Many people are not sure about switching to solar energy, since the investment to pay for the panels is not very economical. However, if we think about it in the long term, it is a good alternative to save money in the future.

There will not always be constant energy

Solar energy depends only on solar radiation; therefore, we cannot calculate exactly how much electricity will be generated daily. The weather plays a key role. Depending on whether the environment is sunny or cloudy, you may get more or less energy than you need.

It pollutes a little

As we explained before, solar energy is a clean, renewable and sustainable type of energy. However, the realization of solar panels and their respective transport leave a carbon footprint in the environment and the atmosphere, although much less than with other types of energy.

Limited power and capacity

The size of the solar panels is very relevant, in the sense that a small one will store less energy than a larger one. This means that the power can be limited when it comes to covering the needs of a household.

Panels are not suitable for all types of roofs

Some materials used on older buildings, such as slate or cedar shingles, can create problems when installing solar panels. In addition, getting certified labor also increases upfront costs.

Consider solar energy

Solar panels are a great alternative for those looking for a clean, sustainable, renewable, long-lasting option that helps improve the environment. However, it is important to have as much information as possible regarding the advantages and disadvantages of solar power before making the decision to make the initial investment.

It is the energy of the present and the future, due to its many benefits for the ecosystem. It is of vital importance to know the situation in which we are now to consider whether it suits our needs. Would you dare to use it in your home?


  1. Hey, Just want to say thanks for sharing this informative content about solar energy for homes. I have been searching for information about solar panels and found it in here. Keep writing – it was really helpful!

  2. I really appreciate you talking about how economical solar energy can be for your home. This is something that I can see being a great benefit to us here as we’re trying to do everything for our house to make it extremely cheap to run in the long run. I’ll get a solar expert to help me install one of these systems right away.
