The solar energy and its positive impact on society

In general, technological innovation enables solar energy through solar panels to capture the sun's heat and use the energy to generate energy and electricity for homes, buildings, cities and companies, as solar energy helps to maximize the earth's resources and conserve energy, in addition to that also solar energy can produce many social benefits For those countries that use solar energy systems.

Solar water heater components

In general, a basic solar water heating system needs many components such as: a heat collector, storage tank, and connection pipes, and the first solar water heating system was made in the 1970s, and many of these systems are still in operation, however hot water technology has developed Solar system to become: an energy-saving option in some climates with freezing temperatures and limited sunlight, and thus this means that the components of contemporary water heating systems are more diverse and complex. and the solar water heater components is :

Heat complex:

The solar hot water collector can be as simple as a black tank filled with water, and flat panels are the most used and common type of heat collectors, and there are two main types of flat panels: the first type that is easy to build and is basically: a flat black box It is insulated and filled with a copper coil or plastic pipe and covered with glass.

The second type looks similar to the first on the outside, but usually contains a series of copper tubes covered with glass evacuated tubes instead of plastic tubes, as these tubes allow efficient heating of the liquid inside while minimizing the radiative heat loss.

Storage tank:

A conventional water heater makes a suitable tank to heat water with solar energy, and it is possible to connect the water heater in homes to an open heating circuit, however, the tank for the closed loop system must have a heat exchanger and pre-installed ports for both the heating liquid and the water.

It is usually easier to purchase a tank specifically manufactured for use in: a closed loop system rather than converting a conventional tank, and also some systems that use the back-drain approach (when water is drained from the coils at night) require a separate storage tank for that water.

other ingredients:

The temperature of the water in a solar water heater can become hot like the water in a conventional water heater or even hotter, so the solar tank will usually need a relief valve for both temperature and pressure, and also because the water may expand when heated, most systems need a tank Expansion and circular pump.

Moreover, the rear drainage system needs a temperature sensor and a pump to heat the water, and these pumps and sensors are usually connected to an electronic control station.

The positive effects of solar energy on society

Job creation:

When cities or companies decide to build or operate solar energy facilities, projects often help create many jobs, for example there is a great need for workers to plan, develop and implement the project, build a solar power plant, manage equipment and operate the facility, and thus workers can achieve many Of the new jobs as a result of the use of a city or state of solar energy facilities to generate electricity for the region, and this in turn will help reduce the unemployment rate in a particular region.

Stimulating the economy:

There are many ways that the use of solar energy can help stimulate the economy in the affected areas, and with more people being able to find work as a result of the increase in the number of jobs created through developing and operating solar panels, more people will have money. To contribute to the nation's economy.

Also, manufacturing solar energy is less expensive than burning fossil fuels (which is the traditional method of generating electricity), and therefore if many companies or homes decide to use solar energy systems to run electricity in their homes or buildings, their electricity bills could be much lower, than if They might use energy generated from fossil fuels, and over a long period of time the difference in cheap electricity bills could become very large.

the health:

Generating power from solar panels usually results in less pollution in the air compared to burning fossil fuels, and thus solar energy is clean energy, and this in turn means that most cities or regions that decide to use solar energy to power buildings will have cleaner air quality in the region, which in turn It can make the citizens and workers of the area healthier.

Moreover, studies indicate that burning fossil fuels helps facilitate global warming, however, given that solar panels may emit a very low amount of dangerous pollution into the air - solar energy does not harm the atmosphere or even cause global warming. Thus, if regions decide to use solar energy to generate electricity, the transformation will also help reduce the effects of global warming such as: rising sea levels and intensifying storms.
