Solar energy today

The normal direct irradiance (or perpendicular to the sun’s rays) outside the atmosphere is called the solar constant and has an average value of 1366 W/m² (corresponding to a maximum value at perihelion of 1395 W/m² and a minimum value at aphelion of 1308 W/m²).

Radiation absorbed by the oceans, clouds, air and land masses increases their temperature. The heated air is that which contains evaporated water rising from the oceans, and also partly from the continents, causing atmospheric circulation or convection. As the air rises to the upper layers, where the temperature is low, it decreases in temperature until the water vapor condenses to form clouds. The latent heat of water condensation amplifies convection, producing phenomena such as wind, squalls and anticyclones.

[8] Solar energy absorbed by the oceans and land masses keeps the surface at 14 °C.[9] For the photosynthesis of green plants, the energy of the sun’s rays is used as a source of energy.

Benefits of solar energy

About three-quarters of the mass of sunlight contains hydrogen (~73%). The remainder is made up of primary helium (~ 25%), with much smaller amounts of more significant components, such as oxygen, carbon, neon, and iron.

Scientists have calculated that the sunlight will become large enough to engulf the current orbits of Mercury and Venus. In fact, when this happens, the Earth will no longer exist.

After this happens, it will undoubtedly lose its outer layers, becoming a thick air-conditioned celebrity called a white dwarf. It will no longer generate energy through combination, but will certainly continue to radiate and produce heat from its previous melting amounts.

In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of metal electrodes in a conductive solution.2 He observed that the cell produced more electricity when exposed to light.

Who invented solar energy

The distributed generation of electricity with solar energy, which is the electricity that consumers could generate in the same place where they consume it (on their roofs, for example), is also strongly restricted, hindered and limited by a regulation issued by the Executive Power, and it is not with this type of policies that the country is going to develop. While the world is rapidly adopting new technologies to generate electricity, which are increasingly cheaper, in Costa Rica they are limited and hindered, thus favoring more expensive sources of electricity generation.

Which country pioneered the use of solar energy?

The application of solar energy in societies dates back to ancient Greece with the lighting of the torch in the Olympic Games through mirrors that concentrated the sun’s rays to mitigate the inauguration of one of the largest sporting events in the world.

Solar energy was not only used for lighting or fire, but also for heating the home since ancient times and, under this premise, it was the Greeks themselves who built their architecture so that the porticoes on their facades would allow buildings to be free from the sun during the summer and ideally sunny in the winter.

The development of photovoltaic energy began in 1838 with the French physicist Alexandre Edmond Bequerel, while experimenting with batteries, he realized that their voltage increased when they received solar radiation, but it was not until the early 1900s that Heinrich Hertz discovered the photoelectric effect and Albert Einstein proposed a mathematical description of this phenomenon. And, it was not until the 1950s that the first photovoltaic cell was created at the Bell Corporation laboratory.
