What is solar energy?

Solar energy, also known as solar energy, is the energy emitted by sunlight in the form of heat and light, It is the product of nuclear interactions in the nearest star, The sun. Amazing energy produced far exceeds current global energy needs, And if it’s harnessed and used properly, They can meet all future energy needs.

The importance of solar energy

The importance of solar energy lies in the fact that sunlight facilitates the evolutionary processes of organisms, In addition to the role of these rays in hydropower and wind power, It is also responsible for the photosynthesis of plants to produce food and biomass. Production and growth of food crops and drying them to protect them from damage, in addition to using agricultural greenhouses to increase heat. Moreover, solar energy is the most important source of energy in the so-called renewable energy group, and it is worth noting that the importance of solar energy as a renewable energy source is increasing because it is not decreasing and has strong characteristics. At a time when levels of fossil fuels, oil, coal and natural gas have declined significantly.

Solar exploitation applications

to use solar energy a large number of old and modern applications in our lives, The following is an explanation:

Old apps

Here are examples of older applications for solar energy development:

Applications of architecture and construction

steering the house and its windows towards the sunshine, Where light and heat are used in the house, Also choose the type of building materials so that you can absorb and store heat.

Agricultural applications

grown in a greenhouse or thermal energy, which turns sunlight into heat, This method has been reported to help facilitate the cultivation and growth of plants in the off-season.

Applications in sterilization

In some areas, The use of a specially adapted solar cooker has been reported to sterilize medical instruments in clinics, Studies have also shown that bacteria, viruses and parasites can develop in water when exposed to sunlight for several hours. decrease More than 2 million people in developing countries use these methods every day.

Different applications

Various old applications for solar energy use are as follows:

Modern applications

Examples of modern applications for solar energy use are solar power generation, The most famous explanations for these methods are:

Solar cells

Solar cells convert sunlight directly into electricity, One cell produces less energy, So a large number of cells must be grouped together, Like solar panels on the roof of the building, to generate enough power, This type of level cell is used in satellite networks and space communications, On the ground These batteries were used in calculators, watches, homes, and commercial buildings, And even stadiums. Kaohsiung World Stadium in Taiwan was built in 2009 using 8,800 solar panels above the stadium.

Solar energy concentration technology

In this technique, The heat of the sun is used instead of radiation as in the solar cell, So there is a set of lenses or mirrors that focus light from the sun in the form of a beam, Which is used to start a water heater that produces steam in turn which stimulates the turbine to start generating electricity.

Advantages of solar energy

There are many advantages to distinguishing between solar energy and electricity generated from it, The most important are:

The most popular household uses of solar energy

After starting to use solar applications and compatible with modern technology, They are used in homes in many forms, the most famous of which are:

Solar storage methods

Solar energy can be stored in several ways, Among them:
