Solar Panels: The advantages and disadvantages

Solar panels are a possibility if you want to consume, clean energy and save money in the long run. We indicate the different advantages and disadvantages of using this renewable energy for your home, as well as the future horizon of solar energy.

1. Advantages of solar panels in your home

The use of solar energy has the following benefits that are good to know. We detail them to make it easier to choose what you want with criteria:

1.1 Zero polluting emissions

The main attraction of solar energy is that, unlike other sources, it does not generate polluting emissions, either directly or indirectly. Once you install the solar kit there will no longer be any greenhouse gas emissions. This is a good reason to opt for the installation of these devices.

1.2 Energy saving

The installation of photovoltaic panels is an initial investment, it is true, but in the medium term the energy savings that are achieved are very high. The electricity bill will be cheaper and, in addition, with the bidirectional meters you will have the possibility of returning the energy that you do not use and “reselling it”. This is an option for those who want to save on energy consumption.

1.3 Does not generate noise

One of the aspects to highlight of solar energy is that it does not generate any type of noise , unlike conventional electric power generators. If you do not want to endure annoying sounds, this is a possibility to gain in well-being.

1.4 Compatible with other energy classes

Photovoltaic energy is compatible with other sources and, in fact, many homes have two installations for conventional energy to work when the other does not. This is the way to make a gradual transition and, above all, to avoid problems so that nothing happens.

1.5 Available worldwide

The sun is an inexhaustible source of energy throughout the planet , at least in the very long term, because it is expected to continue to emit energy for 5 billion years. It is important to indicate that energy is obtained from the sun in places where there are no other options because in remote areas this is a way for a small installation to function autonomously.

2. Disadvantages of solar energy

Although the use of solar energy is globally positive, there are a number of negative aspects that you also have to assess. It is important to remember that the energy mix offers several possibilities and that, depending on the location, you may be interested in one source or another.

2.1 You have to make a high initial investment

The installation of solar energy panels requires a high initial investment, which ranges between 600 and 800 dollars per square meter of solar panels. There are differences in draft depending on the company, but you should start from this initial calculation so as not to get any unpleasant surprises. This means that betting on this structure can be expensive at first and this circumstance discourages some individuals.

2.2 Limited power

A solar panel has limited power and, for this reason, the use of this type of energy is sometimes not enough, by itself, to cover the needs of a home. Consider that a small house in a temperate zone does not consume less than 7 kW per day and a standard panel only generates 250 W.

2.3 Climate dependence

This inconvenience must be relativized because there is the ability to predict or make average hours of sunshine per year and per day, but in any case we do have this problem. If the weather in your area is changeable and you do not have much capacity to store energy, perhaps you may have problems ; in places where there is no sun it is not the best option either.

3. Types of solar panels

Solar panels are variable depending on the size and power, but above all we can highlight two types that are the most used:

3.2 Photovoltaic solar panels

Photovoltaic panels are made with silicon cells that collect energy from the sun to transform it into alternating current. This is the panel that is most used in self-consumption structures and can be of the monocrystalline or polycrystalline type . This type of solar panel has different applications depending on the climate and the profitability you expect from each case.

3.3 Thermal solar panels

The thermal panels are less common and are used mainly in community facilities to generate heat or steam. It is important to indicate that there are high, medium and low temperature collectors. The objective of these panels is to generate energy, but it is true that they are not usually used for day to day.

4. The future of solar energy

Renewable energies have a horizon of generalization in the medium term and in Australia 2030 has already been set as the year for there to be a consumption of 35% of renewable energies. In the automotive sector, it is expected that combustion engines will no longer be produced by 2040 and industry will also bet on this goal.

Solar energy is an interesting alternative in places where conditions are favorable and, above all, in small buildings and for self-consumption . This is important if you are interested in building a private house and you want to have an autonomous and sustainable energy generation path.

In Australia the generation of solar energy has had ups and downs due to contradictory legislation and the misnamed “sun tax”, but in the short term a rebound in use is expected.

5. Conclusion

Solar panels are an option for those who want clean energy, economical, and with a durable structure. Knowing the advantages and disadvantages of using solar energy will help you choose wisely so that you do not have any problems. Do you dare to try them?
