It cannot be denied that it is becoming more and more profitable to use solar energy as a renewable energy source. This is because it is an unlimited source of energy that we receive from the sun and that can be transformed by solar panels into electrical energy. However, we have the doubt of how to install solar panels since there are many aspects to take into account so that the performance is the best possible.
For all this, we are going to dedicate this article to tell you how to install solar panels.
Advantages of solar energy
In order to install solar panels, it is better to first know what advantages we will have of installing this type of energy in our home. Solar energy is totally free of any polluting residue and is currently placed in the best alternatives to reduce greenhouse gas emissions. And it is that fossil fuels such as gas, oil and coal are polluting sources that are causing environmental problems on a global scale such as climate change.
Since we are going to install solar energy in our home we must know what the advantages are:
- We will save on the electricity bill. This is because the production of solar energy is completely free and tax free. Furthermore, it is an unlimited energy.
- We will have independence from variations in the price of electricity.
- We will reduce our greenhouse gas emissions.
- We will have tax benefits through the subsidies that exist from self-consumption.
- The maintenance of the solar panels is minimal since it has quite simple technologies. Although the initial investment has a higher cost, we can recover this investment over the years.
- Within renewable energies, photovoltaic solar energy is one of the safest.
What is and how does a solar panel work
We are going to see step by step what we must do to install solar panels. The first thing is to know what a solar panel is and how it works. These plates are made up of photovoltaic cells that are manufactured with different semiconductor materials. These materials are what allow us to transform the energy that comes from the sun into electrical energy to be able to use it in our homes.
Energy conversion occurs thanks to photovoltaic effect. In this effect we can see how an electron is able to pass from the negatively charged panel cell to the other with a positive charge. During this movement a continuous electrical current is generated. As we know, continuous electrical energy is not used to supply electricity to a home. We need alternate electrical energy. Therefore, we need a power inverter.
This direct current energy passes through the current inverter where its intensity frequency is adjusted transforming into alternating current. This current can be used for domestic use. Once we have this energy, we will use everything necessary for our own consumption. It is possible that on numerous occasions we are generating more electrical energy than we consume. This excess energy is known as excess energy. We can do some things with it: on the one hand, we can store this energy with batteries. In this way, we can use this type of stored energy when there is not enough solar radiation to power the solar panels or at night.
On the other hand, we can pour these excesses into the electricity grid in order to obtain compensation. Finally, we can also not use these surpluses and dispose of them by means of an anti-diversion system. This is the worst of the three options since we are wasting energy that we have generated.
How to install solar panels step by step
Due to the high investment that this type of installation requires, it is better to know in depth its entire operation and the steps that will be needed for its installation. And it is that, solar energy has a negative point that extends to all people. This negative point is the initial investment. Usually, the useful life of a solar panel is approximately 25 years. The initial investment is recovered after 10-15 years, depending on their quality.
We are going to explain step by step how to install solar panels. We must first request a quote for the installation of the plates. To do this, we must put you in contact with a company that is dedicated to installing this type of panel and it will ask us for certain information with which we can give you enough information so that they can prepare an initial budget.
Once they have the data, the panels will be installed. The company usually performs the installation as long as various requirements are met:
- One of them is that the company will be in charge of requesting the permits and inform the consumer about the subsidies that exist at that time.
- Once this information has been transmitted, the consumer is the one who values the budget provided by the company and will be the one who dictates if he authorizes the installation of the solar panels on the roof.
When the consumer approves the installation of the solar panels, the company will proceed with their installation. Among the components that have a photovoltaic installation we find the following elements:
- Solar panels: They are responsible for producing the sun's energy in the form of electrical energy. If our area where we live has more solar radiation, we can transform more energy.
- Power inverter: It is in charge of enabling the continuous energy transformed by the solar panels to activate it so that it is useful alternating current for domestic use.
- Solar batteries: They are responsible for storing excellent solar energy. They will have a longer useful life the lower the depth of discharge. The ideal is to carry out shorter charges and not let them discharge in full.
Normally the solar panels are installed on the roofs of the houses to avoid the projection of shadows as well as to prevent damage and the accumulation of waste.
I hope that with this information you know how to install solar panels.
