Solar energy is based on radiation from the Sun.
Solar is a concept that, according to its etymological root, has various meanings. When the term comes from the Latin word solāris , it is linked to that related to the Sun (the star around which the Earth rotates).
In this way, we can mention different ideas. Solar time is time that is measured according to the apparent movement of the Sun over a certain horizon. In this way we can speak of solar time , solar day , solar year , etc.
The solar wind , for its part, refers to the movement of the outer layer of the Sun, called the solar corona and formed by plasma . This wind is a radiation that the Sun emits in different directions and continuously.
solar energy
Solar energy is called the energy source that comes from the Sun's radiation. It is renewable energy: it is not exhausted with its use. Furthermore, it is considered clean energy since it does not produce pollution.
Solar energy has experienced a notable increase in recent decades due to other benefits it offers such as the following:
- It is a great alternative for those areas where it is almost impossible for power lines to reach.
- It has minimal maintenance, so it does not pose any type of concern for the user in question.
- It represents a significant economic saving for the individual, because they will not have to make the expense of electricity from the traditional network.
- Because it is much safer, so it does not put those who use it at risk.
- Because their installations do not require a specific space to be placed: they are, as a general rule, located on the roofs of buildings.
Solar panels can be installed in different locations.
The concept linked to soil and lineage
Solar can also come from soil . In that case it can refer to a built land or land susceptible to construction. For example: "I still haven't decided how I'm going to take advantage of the lot that belonged to my father," "The government expropriated a lot located next to the river."
The idea of solar, meanwhile, can refer to a lineage or a descendant . In the field of genealogy , the solar house is the one that was the first where a notable individual bore his surname. From this solar house other houses can be generated, linked to descent and changes in surname.
