Energia Solar


Next we will analyze the concept of solar cell, that is, we will see the definition of solar cell .

A solar cell uses the energy from the sun to transform it into electrical energy .

These devices are composed of solar cells made of  crystalline silicon , which has the property of converting sunlight into electricity.

The larger the panel, the greater the energy it receives from the sun and therefore the greater the generation of electricity.


solar cell  is a device capable of converting the energy coming from solar radiation   into electrical energy. The vast majority of  solar cells  that are currently commercially available are mono or polycrystalline silicon



To be  able to work, the solar cells must receive the solar rays directly . Its main use is of domestic type, since these are usually placed on the roofs of homes to provide electricity to appliances.

Solar cells are the fundamental component of solar panels.

There are  three types of solar panels:

  • Photovoltaic:  are those panels described above, capable of generating enough energy to meet the needs of the home.
  • The thermal:  this  kind  of panels should be used in homes that have an optimal reception of sunlight and also have enough space to place them, since they are larger than photovoltaic, because otherwise they would not be efficient. Thermal panels work the same as photovoltaic panels , with the only difference being that thermal panels  contain a liquid that absorbs  heat .
  • Thermodynamics:  these are the most used, nowadays in homes, since they are more economical, more efficient and can be used for many more things. Among its advantages is that it can absorb energy, even if it is cloudy or raining. This means that these panels have the characteristic of  capturing any type of energy  in any environment, as long as the outside temperature is not less than 0 degrees.

Solar panels are beneficial for the environment because  the energy they produce is clean and renewable ; besides contributing with the  energetic saving , his installation is fast, the maintenance is minimum and have long useful life.

It is true that at first, being able to install these devices would  be a bit expensive , however, everything that is invested can be recovered over  time  and people will be rewarded by receiving free electric power.

Among the negative aspects, we could mention the  weather , since panels such as photovoltaic  only work if it receives direct sunlight , meaning that on a cloudy day it will not work properly.
