Solar energy is one of the most important renewable energy sources in the world. Taking advantage of sunlight, solar energy is transformed into electricity in a sustainable way, helping to reduce dependence on fossil fuels and mitigate climate change.
Definition of solar energy
Solar energy refers to electricity generation using sunlight as a source of energy. Unlike fossil fuels, such as coal and oil, solar energy is renewable, inexhaustible and does not produce carbon emissions during electricity generation. Solar panels, also known as photovoltaic panels, are the key devices used to convert sunlight into usable electricity.
How was solar energy discovered?
The discovery of solar energy goes back to ancient times, when the capacity of solar light to generate heat was one of the first uses of solar energy. However, the use of solar energy as electricity source It was developed thanks to the invention of photovoltaic technology. Through the use of semiconductor materials such as silicon, photovoltaic solar panels transform sunlight into electricity efficiently, thanks to the process of photons that generate free electrons.
Solar energy production process
The solar energy production process involves the transformation of solar light into electricity thanks to photovoltaic solar panels. These panels, made up of solar cells, capture sunlight and transform it into direct current (DC) electrical current..
Then, the direct current is transformed into alternating current (AC) through an inverter, which makes it usable for homes, buildings and businesses. In addition to solar energy photovoltaic, Solar thermal energy is another form of solar electricity generation. This process uses sunlight to heat fluids, such as water, generating steam. Steam is used to drive turbines, which generate electricity. Solar thermal energy is widely used for water heating in large-scale homes, buildings and solar power plants.
Types of solar energy
Solar energy can be classified into two main types: solar energy photovoltaic and solar thermal energy:
Photovoltaic solar energy
Photovoltaic solar energy is the most common form of solar electricity generation. Using photovoltaic solar panels, it transforms sunlight into electricity efficiently. These solar panels photovoltaic, made up of silicon solar cells, generate electricity when sunlight hits them, releasing electrons and generating direct current (DC) electrical current.
This direct current is transformed into alternating current (AC) by means of an inverter, which makes it usable for homes, buildings and businesses.
solar thermal energy
Solar thermal energy, as mentioned above, uses sunlight to heat fluids, such as water, generating steam. This steam, in turn, is used to drive turbines and generate electricity. Solar thermal energy is widely used for water heating in large-scale homes, buildings and solar power plants.
Uses of solar energy in El Salvador
According to Statista, a German online platform specialized in collecting and display of data, the installed capacity of solar energy in El Salvador has been increasing from 121 megawatts to 478 in 2021
According to information from National Energy Council (CNE), in less than a decade, more than 40 domestic and foreign companies have invested in projects between large, medium and small with an approximate value of $1,000 million. In 2021 alone, a total of $150 million was invested in this item.
The use of the solar energy In El Salvador it has increased in recent years, thanks to its potential for generation of renewable and sustainable electricity. Next, we will explore two of the main uses of solar energy in El Salvador, at the level of homes and businesses.
solar energy and housing
The use of solar energy in homes The savior It reduces dependence on electricity generated by non-renewable sources, such as coal and oil. The installation of photovoltaic solar panels allows efficient use of sunlight, transforming it into sustainable and reliable electricity for domestic use. Households that use photovoltaic solar energy enjoy economic benefits through the reduction of the electricity bill, in addition to contributing to the reduction of the carbon footprint and environmental sustainability.
solar energy and business
Solar energy has also found great potential for use in the field of business in El Salvador. Businesses that opt for the installation of photovoltaic solar panels can significantly reduce their electricity costs, which, in turn, promotes sustainability and efficiency. In addition, the installation of photovoltaic solar panels demonstrates the commitment of companies to sustainable development, generating long-term economic benefits and contributing to compliance with sustainability goals.
American Park It is the largest free zone in El Salvador with more than 220,000 square meters of industrial roof, more than 26 international companies and has generated a positive impact on the communities, generating 12,000 sources of direct employment of which 65% of the workforce They are women
The solar plant that started in American Park gave life to Aristos Energy, another division of Aristos Group, which was born with the purpose of generating green and renewable energy for all the real estate developments of Aristos. Aristos Energy works in synergy with Aristos Real Estate, for the development, construction, administration and operation of solar photovoltaic power plants on roofs and floors.
The other industrial parks of Aristos Real Estate that use solar energy efficiently are: Sirius Industrial Park, Apollo Industrial Park, Orion Industrial Park and El Progreso Industrial Park.
Cost and accessibility of solar energy
Is solar energy really free?
Solar energy is considered as a free form of electricity generation, since sunlight, a solar energy source, is inexhaustible and has no associated cost. However, the installation of photovoltaic solar panels, necessary to transform sunlight into electricity, requires an initial investment and continuous maintenance. Although sunlight is free, the installation of solar panels photovoltaic It implies a cost, which can vary depending on the scale and capacity of the photovoltaic system.
Cost Comparison: Solar vs. Conventional Energy
By comparing the costs of solar energy with the electricity generated by non-renewable sources, such as coal and oil, solar energy becomes more and more competitive. Although the installation of photovoltaic solar panels requires an initial investment, the electricity generated by solar photovoltaic panels can significantly reduce the bill for long-term electricity. In addition, the electricity generated by solar panels photovoltaic It can be used efficiently, reducing conventional electricity consumption and, consequently, associated costs.
Benefits of solar energy
Solar energy offers a wide range of benefits, both from an environmental and social and economic point of view. In this section, we will explore some of the key benefits of solar energy, including its environmental advantages, social benefits and its ability to contribute to economic savings.
