Learn everything about solar panels: anatomy, history, present and future

In recent years, the use of renewable energies has begun to be taken into account thanks to the environmental and ecological movement. One of the main artifacts used for this purpose are solar panels and, although it seems like a very modern and innovative idea, the reality is that the first discoveries related to this energy were made in 1920, by the hand of Albert Einstein when he described the photovoltaic effect, which gave him a Nobel Prize. The photovoltaic effect is simply the process by which solar energy is transformed into electricity. Of course, for this theory to be carried out, a mediating element was needed, called photovoltaic cells, developed in 1954 by Daryl Chapin, Gerald Pearson and Calvin Fuller. Each solar cell is about 10 square centimeters and the solar panel makes up for around 60 cells (although it depends on the manufacturer). Then, it is covered with a plastic called EVA, which withstands very high conditions and temperatures, allowing light to pass through but not ultraviolet rays. At the same time, they also have an inverter, which transforms the current received (direct) into that of daily use (alternating).

Of course, solar panels are a collage of very important scientific discoveries.

The present and future of solar energy

The current facilities contemplate all the points of sustainability and optimization. Thus, it is very common to see or hear about solar farms: a large group of panels installed in fields. This makes it possible to optimize spaces and resources since, by increasing the number, the number of electrical devices that can be fed in the same area or to the same company or neighborhood increases considerably. At the same time, the space can be used for grazing animals, benefiting local farmers. It would be a reciprocal exchange, since the solar panels are favored by the humidity released by the plants.

A very present trend is the installation with a tracker, that is, an intelligent motor that captures the position of the sun and moves the honeycombs so that they capture the greatest possible rays. When it was thought that a solar panel could not be more efficient, Stanford University in the United States presented a project on an installation capable of making the solar panel continue generating energy after the sun has set. Based on the principle of radioactive cooling, the device could recover the heat given off, continuing to work even at night. Science is also advancing in the creation of solar cells, which would transform simple windows into transparent panels, allowing power to be supplied to a house or industry.

How to buy a solar panel?

Many companies offer various panels with their respective benefits. With so much on offer, it can seem difficult to choose the right one. Two points are the most important: certification that complies with the standard required in each country and guarantee. This is how Sunny Future fulfills it, the company of Colombian solar panels and Holland expert in solar energy.

Definitely, the environmental trend is gaining ground in all areas and, if we know anything, it is that the implementation of renewable energies is just beginning.
