Solar energy pros and cons


1- Renewability

Speaking about solar energy, first, it is necessary to mention that this is a renewable energy source, in contrast to fossil fuels - coal, oil, gas. According to NASA, about 6.5 billion years later, the inhabitants of the Earth have nothing to worry about - about as much the Sun will warm our planet with its rays until it explodes.

2- Abundance

The potential of solar energy is huge - the amount of solar energy reaching the earth is 120 thousand terawatts. and this is 20 thousand times higher than the global demand for it.

This benefit comes at the second position in solar energy pros and cons.

3- Persistence

In addition, The sun's energy is constant and we cannot overuse it from our demand. So it will be enough for future generations.

4- Availability

Among other advantages of solar energy, it is available in every part of the world - not only in the equatorial zone of the Earth but also in northern latitudes. For example, Germany ranks first in the world using solar energy and has its maximum potential.

5- Ecological cleanliness

In the light of recent trends in ecological cleanliness of the Earth, solar energy is the most promising industry, which partially replaces the energy received from non-renewable fuel resources and, thus, acts as a fundamental step towards protecting the climate from global warming.

This benefit comes at the 5th position in solar energy pros and cons.

6- Silent

Protected from a noisy environment, solar energy is a silent source of electricity. For example, solar panels quietly convert solar energy into electricity.

7- Cost-effective, low maintenance

By switching to solar panels as an autonomous source of energy, owners of private homes receive tangible savings. The maintenance of solar-powered systems is very cheap - it is only necessary to clean the solar cells two to three times a year, and the manufacturer's warranty on them is 20-25 years.

8- Extensive scope

Solar energy has a wide range of applications. We use it in regions where there is no connection to a centralized power supply system.

9- Innovative technologies

Every year, technologies in solar panel production are becoming more advanced.

Experts introduce thin-film modules directly into building materials at the stage of construction.

The Japanese have recently introduced an innovative system of transparent storage elements for window glazing.

Modern advances in nanotechnology and quantum physics allow us to talk about an increase in the power of solar panels by 3 times.

This benefit comes at the last position in solar energy pros and cons.

Disadvantages of Solar Power Sources

1- High cost

There is an opinion that solar energy belongs to the category of an expensive resource.

This is perhaps the most controversial issue of all the positive and negative aspects of its use.

Because the construction of a house with solar storage elements costs a considerable amount at the initial stage, many states encourage the use of this environmentally friendly energy source by issuing loans and drawing up leasing agreements.

2- Volatility

Because there is no sunlight at night, and on cloudy and rainy days, solar energy cannot serve as the major source of electricity. But, in comparison with wind generators, this is a more stable option.

3- The high cost of energy storage

Homeowners require solar panels, and rechargeable batteries, to store energy and use it continuously. They have to spend a lot of money to meet this need.

4- Minor pollution

Although, in comparison with the production and processing of other types of energy, solar energy is the most environmentally friendly.

But some technological processes for manufacturing solar panels release greenhouse gases, nitrogen trifluoride, and sulfur hexafluoride.

5- Using expensive and rare components

The production of thin-film solar panels requires the cadmium telluride (CdTe) or indium gallium copper selenide (CIGS), which are rare and expensive.

6- Low power density

One of the important parameters of the power source is the average power density, measured in W / m2, and characterizing the amount of energy that can be obtained from a unit area of ​​the energy source. This indicator for solar radiation is 170 W / m2 - this is more than other renewable natural resources but lower than oil, gas, coal, and nuclear energy. For this reason, it requires a significant area of solar panels to generate 1 kW of electricity from solar heat.
