The number of countries focusing on simple solar energy is growing at an alarming rate. Only in 2014 has it increased by 20 percent. According to energy source researchers, this same renewable energy source is considered the primary technical boon of the future. Germany; seems to have slowed down in the last few years among the countries involved in this technology and has a leading role. Around the world, solar energy harvesting networks are being installed everywhere. Even at the price level, diesel; by gas, Coal, and atom; is lower than power generating networks. Worldwide in 2014, According to provisional assessments, 45 gigawatts of solar power generation networks were installed, according to experts. In the future, the mentioned energy source will become more widespread worldwide. This year, more than 50 gigawatts; After five years, between 100 and 150 gigawatts of electricity will be supplied from solar power grids. This is said by those who are the leaders in European solar energy research. At the Fraunhofer Institute, the energy resource manager is Professor Dr. Ike Weber.
“Global; Solar light and heat Sabina to electricity conversion special board (Photobiltec) is the market of Dera. The price is so low that it is widely sold that the price paid for this electricity is low, i.e., less than 10 euro cents per kilowatt-hour. Depending on the size of the network, it can be paid from 8 to 12 cents. But in countries that get plenty of sunshine and heat, The fee is 5 to 7 or 8 cents. The level of competition in setting up a system that directly converts sunlight and heat into electricity from a special board (photovoltaic) that converts sunlight and heat into electricity is not so high. »
One of the modern renewable energy sources that started in Europe and Asia has gained the opportunity to expand in Latin America and Africa overnight. It is well known that Africa is one of the parts of the world that gets the most sunlight and heat. However, especially in the countries south of the Sahara desert; The World Bank revealed that each family receives less than 25 percent of the electricity service; Even in rural areas away from cities, the electricity supply is only about 10 percent. Electricity service is interrupted on an average of 56 days a year. Due to the rapid economic growth of this sub-continent, approximately 40 billion dollars are required to be spent annually to address the energy supply problem. For example, Ethiopia, one of the many sub-Saharan countries, has 55% of the electricity service provided throughout the country, and in the Gregorian year of 2015, in cooperation with the United States company Green Technology Africa, generated 300 megawatts of electricity in one year; She says she plans to raise the rate to 75 percent. Besides water power from the sun, It is known that there is an alternative possibility of using steam and wind energy underground.
Eritrea; By installing 12-megawatt electricity generating networks in different parts of the country, especially the villages in Funtar, it has reached 65 percent of users. Areas where it is possible to find a source of electricity other than solar energy, have also been studied and mapped. To keep costs down, parts of the light and heat, as well as the switchboards and batteries, are made locally.
South Africa plans to increase its renewable energy supply from 1 percent in 2012 to 12 percent by 2020 to generate 3,725 gigawatts! From sub-Saharan countries, South Africa is the country that developed the first network called Concentrated Solar Power through the special glass.
The unique light and heat Sabina to electric switchboard factory is unmatched in Africa.
In Europe, Apart from Spain and Italy, solar power grids were first developed in Germany. Since 2013, unique light and heat absorbers and electrical converter boards for solar energy networks have been produced in large numbers. More than what Germany and Italy pay. China, Japan, and the United States are involved in the production. According to the preliminary study, in 2014, 13 were in China and nine in Japan; In the United States, seven gigawatts of great light and heat Sabina to electricity converter boards were produced. German production in this regard, The 2 gigawatts offered were much reduced. In fact, among the 127,000 who were initially employed in this sector, More than 50,000 people have been laid off. However, in 2010 and 2012, seven gigawatts of electricity per year were produced in particular light and heat exchangers. So says Jörg Mayer, CEO of another company called Solar Wirtschaft.
“What was the spirit then? They all felt that we had fallen behind in terms of productivity. In 2014, the special light and heat Sabina to electricity boards that provide less than 2 gigawatts of power was produced. In the current Gregorian year of 2015, we see that industrial companies are planning to increase production immediately. Therefore, There is hope that we will get out of the international market by not working from the low level of 2014”.
Professor Dr. Ike Weber still has something to say about this.
“In 2014, approximately 45 gigawatts of electricity generation special networks were replaced in the world market; The work is going to expand further in the future. By 2020, the amount of gigawatts is likely to increase by 100 to 150. This is called rapid growth. »
According to Solarworld company spokesperson Milan Nichke, The coming decades will be Africa’s growth period in this respect.
Professor Dr. Ike Weber; When explaining the detailed plans for the future and the hope that new technology holds —
“The law will be implemented from 2017 and 2018; Our detailed plan for the new technique; Now the solar power grid in Freiburg will be blocked. This costs 6 euro cents per kilowatt hour. And in the same network in Valencia (Spain), generating power that can be paid for only 3 to 4 cents per kilowatt hour is not difficult. And this is certainly lower than the current price paid for special light and heat exchangers in Germany. »
China is the leader in selling 80% of the world market light and heat Sabina, and electricity converter boards. “Solarworld” company spokesperson Milan Nichke said it was enough to reach this level because of substantial subsidies from the government. He said Germany would do well to mourn at a high level in this regard.
