The role and significance of solar panels in the 21st century
The energy of the sun as known as solar energy is an actively developing area in the supply of energy to private and public buildings. Solar panels have become so popular nowadays because now we are thinking about ecology and want to spend not that much money, as we all know that solar energy and solar water heaters are cheaper than using electricity. So why should we use more solar energy than electricity? What are the pros and cons of a natural energy source like solar radiation?
So what are the benefits of solar energy?
Renewability.
Speaking about solar energy, first of all, it should be mentioned that it is a renewable energy source, in contrast to fossil fuels – coal, oil, gas, which are not renewable. According to NASA, for about 6.5 billion years, the inhabitants of the Earth have nothing to worry about. Approximately this is how much the Sun will warm our planet with its rays until it explodes. And we all understand that we together will never see the world without the Sun.
Abundance.
Solar energy has huge potential: the Earth’s surface receives 120 thousand terawatts of sunshine, which is 20 thousand times more than the global demand for it.
Persistence.
Furthermore, solar energy is infinite and constant; it cannot be deleted in the process of meeting humanity’s energy needs. Ensuring that there will be enough surplus and for future generations to share. So don’t worry, everyone will get the energy from the Sun. We can use solar energy or a solar water heater as much as we like and want.
Availability.
Solar energy has a number of advantages, including the fact that it is available in every section of the earth, not just the equatorial zone, but also at northern latitudes. Assume Germany is currently the world leader in solar energy utilization and has reached its full potential. Every year all counties in the world want to reach the result as Germany.
Environmental friendliness.
In view of the most recent trends in the fight for the Earth’s ecological purity, solar energy is the most promising industry. As it largely substitutes energy derived from non-renewable fuel resources and. As a result, works as a critical step in preventing global warming. Solar power plant manufacture, transportation, installation, and use produce virtually no hazardous emissions into the atmosphere. Even if they are present to an insignificant degree, compared to traditional energy sources, this has almost zero impact on the environment.
Silence.
Due to the fact that in systems on the solar resource there are no moving nodes, such as, for example, in generators, power generation is silent.
Economy, low maintenance.
By switching to solar panels as an autonomous source of energy, owners of private houses receive tangible savings. It is also important that the maintenance of power supply systems on solar batteries is characterized by low costs – it is necessary to clean the solar cells only a few times a year, and the manufacturer’s warranty for them, as a rule, is 20-25 years.
Wide range of applications.
Solar energy has a wide range of applications – from generating electricity in regions. Where there is no connection to a centralized power supply system and desalination of water in Africa. And even supplying power to satellites in low-Earth orbit. It is not in vain that solar energy has recently been called “popular”. This name reflects the simplicity of its integration into the power supply system of the house. Both in the case of photovoltaic and thermal elements.
Innovative technologies.
Every year, technologies in the field of solar cell production are becoming more and more sophisticated – thin-film modules. Are introduced directly into building materials even at the stage of construction of structures. In order to convert the constant voltage from the storage battery into an alternating voltage, which can be used to power most electrical receivers in conjunction with solar panels, you can use special devices – inverters.
