The initial uses of solar energy are not well known, however, in accordance with the clay tablets found in Mesopotamia, it’s known that in 2000 B.C. the priestess used to light sacred fire through the sun reflections on polished gold curved mirrors.
The sun throw enough light over the earth every hour, responding to the global energy needs for a whole year. In 2011, The International Energy Agency IEA, stated that “Developing clean energy technologies entails long term benefits, improving world countries power security through the use of local and inexhaustible energy, perhaps even more important disregarding imports, improving sustainability, reducing pollution, mitigation costs preventing inflated prices for fossil fuel.
The mentioned global benefits can be considered as investment for economic development incentive, which need to be applied correctly and be widely circulated.
According to IHS Markit, “In 2016, Latin America becomes the focus of photovoltaic energy”, the conclusion of the quarterly report in Emerging PV Markets Tracker.
According to a new report made from the International Renewable Energy Agency (IRENA), the share of electricity in the world by photovoltaic solar energy might pass from the 2% to the 13% in 2030.
Solar energy is a renewable energy obtained from the use of solar electromagnetic radiation. Solar radiation reaching the earth has been used by human from ancient times through different kind of technologies further improving over time.
Nowadays, the sun heat and light can be used by several collectors such as photovoltaic cells, heliostat or thermal collectors to be transformed into electrical or thermal energy.
According to Greenpeace reports, “The most developed source of energy is photovoltaic energy”. Photovoltaic energy could supply energy to two-thirds of the world’s population in 2030.
Solar energy is a renewable energy source. This means that we cannot stay without this energy source, unlikely to other no renewable energy sources (coal, NPS, fossil fuel).
As long as the sun shines (according to NASA it still has by 6,5 million of miles of years), we are going to be able to use the sun as an energy source. In fact, Scientifics think that the earth will disappear precisely because of the sun in approximately 5 billions of years.
The solar energy potential gets over all the imaginable limits. The earth’s Surface gets 120.0000 terawatts of solar irradiation, which is 20.000 more power than what the whole planet needs.
Sustainability energy sources are able to cover present needs without compromising future generations. Therefore, this being a rich and renewable source, it is sustainable, as this does not generates overconsumption, as well.
Using solar energy does not cause pollution, however, there are some emissions which can potentially pollute associate to production, transport and installation of plants or solar panels, and nevertheless, they are very low comparing with conventional energy sources. Furthermore, solar energy reduces dependency on other nonrenewable sources, which might be a big step in the fight against climate change.
Solar energy is available in all the world. No just can give benefits to countries nearest the Ecuador. Germany, for example, is the country with the largest installed capacity.
Alemania es frío con más potencia instalada se caracteriza por ser uno de los países ubicado en un lugar donde casi no llega el sol.
Many costumers have seen immediate reduction in their energy bills installing self-consumption kits. They also can sell the excess power produced. However, it’s important to be updated with local regulations, since in countries such as Spain have made a debacle for many investors.
Solar energy can be harness for different purposes. It can be used to generate electricity in remote places which can be connected to conventional networks and as in Africa to obtain distilled water or even in the space satellites to generate the energy required.
Solar energy is also known as “People’s Power”. It can be as simple as installing photovoltaic panels and/or solar thermal.
With the flexible and thin panels, the solar energy could best be strengthened in architectonical integration. The japanesse company Sharp offers windows with solar panels which might become common in the near future.
In a normal energy installation there are not movable parts, therefore, there is no noise related. This can be a great benefit respect to other renewable sources, such as wind power.
For anyone installing solar systems there are added incentives
Some countries, there were some incentives in such way that installation cost would be reduced up to the 50%. Spain was profitable, for example, by now those benefits have disappeared.
Most of the solar energy installation required a minimum maintenance. Normally, house panels only need one or two pieces a year which most of the times are included or guaranteed for 20-26 years by the manufactures.
Panels and solar cell innovations and advances of the industry are constant and meaningful. Nanotechnology and quantic physic have achieved to improve three times the efficiency of solar panels.
Through photovoltaic effect, the result of the research made by Albert Einstein, Nobel Prize in physics, who refers to photovoltaic as the capacity to use solar radiation and to convert it in electricity.
