Solar Panels Pros And Cons – 2021

Free Solar Panels for Low-Income Families

Solar panels pros and cons are important today to get them in your home or work. Solar panels are a way to generate your own sustainable energy and save money in the long run. Solar panels are a long-term investment. To help you make a decision, we’ve put together a guide with the various advantages and disadvantages of using this renewable energy for your home, as well as an outlook on the future of solar energy.

No emissions

The most attractive thing about solar energy is that, unlike other sources of electricity, it does not generate any emissions that are harmful to the environment, either directly or indirectly . As soon as you have installed the photovoltaic system in your house, there are no more greenhouse gas emissions. This is a good reason to choose to install solar panels.

Save energy

Installing solar panels pros and cons means a high initial investment, but in the medium term you can achieve significant energy savings . Your electricity bill will drop and you even have the option of “selling” electricity that is not used.


One of the most important aspects of solar energy is that, unlike conventional electricity generation, it does not make any noise. Compatible with other power sources

Solar energy is compatible with other power sources. Many households use two installations : solar energy and conventionally generated electricity when solar energy is not available. Step by step they are switching to solar energy.

Available worldwide

The sun is an inexhaustible source of energy available around the world as it is expected to continue radiating energy for 5 billion years. Solar energy is used in many places where conventional electricity is not available. Thanks to photovoltaic systems, many people are independent of the power grid, even in remote areas.

Disadvantages of solar energy

While there are many overall benefits to harnessing solar energy, there are also negative aspects to consider. Remember that the energy mix offers several possibilities and that depending on your location, one or the other energy source may be of interest to you.

High initial investment

The installation of solar modules requires a high initial investment of 600 to 800 euros per square meter, which varies depending on the provider. However, it is advisable to expect these average prices to avoid nasty surprises. Due to the high initial investment, many are initially deterred.

Limited performance

A solar panel has limited power and for this reason the use of this type of energy is sometimes not enough to meet the total needs of a household. A small house consumes at least 7 kilowatts of electricity per day, while an average solar panel only generates around 250 watts.

Dependence on the climate

This disadvantage is easy to predict, as we are usually able to predict or measure the average hours of sunshine per year per day. If you are investing in solar panels in Spain, you can neglect this factor a little. However, if the weather in your area is changeable, you could run into problems . Obviously, if you live in a place where the sun almost never shines, solar energy is not the best option.

Types of solar panels

Solar modules differ in terms of size and performance. Here we highlight two of the most common types:

Photovoltaic modules

Photovoltaic modules consist of silicon cells that collect solar energy to convert it into alternating current. This is the panel most commonly used in self-consumption structures and it can come in two forms: monocrystalline or polycrystalline . This type of panel has different uses depending on the climate and profitability.

Thermal panels

Thermal panels are less common and are mainly used in communal installations to generate heat or steam. There are high, medium and low-temperature collectors. These panels are used to generate energy, although they are not typically used for everyday purposes.

The future of solar energy

Renewable energies are the future in the medium term. Europe has set that by 2030 35% of its energy will come from renewable sources. The automotive sector is expected to have no internal combustion engines by 2040, and industry will be committed to this goal as well.
Solar energy is an interesting alternative in places with favorable conditions and especially in small buildings and for personal consumption. This is important if you are interested in building a private house and are looking for an autonomous and sustainable way to generate energy.

In Spain, the production of solar energy has gone through highs and lows due to contradicting legislation and the levies mistakenly known as “solar tax”. However, a recovery in usage is expected in the short term.


Solar panels are an option for those who want clean, cheap energy with a permanent structure. After you understand the pros and cons of using solar energy, you can make the right decision for your needs without encountering any problems. Are you ready to experiment with solar energy?
