The countries that are in the latitude + - 35 with respect to Ecuador are known as sunbelt or sunbelt regions because they have the highest levels of solar radiation per year on the planet.
The most important countries that are in the solar belt are China, India, South Africa, Brazil, Mexico. The total number of countries that comprise it are 148.
These countries represent 75% of the world's population as they are home to approximately 5000 billion inhabitants.
These countries have common characteristics such as that they are nations with large amounts of population, they are in an important process of industrial development and economic growth, so there is a very important increase in energy.
But another similarity is the photovoltaic solar potential that they have due to their climatic conditions to be able to produce large amounts of energy not only to supply this region but to export it to other areas of the planet.
There is great international interest in this region, so there are countless companies investing in solar energy, since the development of this technology in this region is still very small.
Currently only 9% of the world's solar installation is in the countries that make up the solar belt. Which indicates all that needs to be done to further promote and develop photovoltaic solar industry in this region. Since it will not only help to generate more electricity for consumption but it will also allow it to improve the quality of life of a large part of the population that is in states of extreme poverty as well as strengthen local economies.
Except for China, which is really investing heavily in solar energy, the rest of the nations are very weak in their capacity to Energy production.
A development of this solar belt would be important not only for the countries that form it but for the rest.
