Introduction to solar energy

When we talk about solar energy, we refer to solar thermal and photovoltaic solar energy:

The solar energy is to heat a fluid using the energy of the sun, which would produce steam and then electricity. This is achieved by sensors or solar collectors.

In solar photovoltaics, sunlight would impact on a photovoltaic cell produces electricity directly.

Advantages of solar energy

When we think of solar energy, there are many advantages that come to our head, it seems that this type of energy we are offered every day with sunrise and, being Spain a place so favored by this star becomes a type of energy that could be described as interesting.

The most important advantage of all is that this energy does not pollute.

When you’re talking of solar energy we can say that is a powerhouse.

It is a system for harnessing energy suitable for areas where power lines do not reach (rural, mountainous islands) or is difficult and costly to transfer.

Solar collection systems that are commonly used are easy to maintain, which makes your choice.

You’ll save money as the technology progresses, while the cost of fossil fuels increases over time because more and more scarce.

The only investment is the initial cost of the infrastructure, it does not require any fuel to operate, and puada amortized over 5 years of implantation.

Photovoltaic solar energy does not require any additional space occupied, it can be installed on roofs and buildings.

The availability of solar energy reduces dependence on other countries for energy supplies of the population.
It is a sector that promotes job creation, necessary for the manufacture of solar cells and panels, as for installation and maintenance of the same.

Solar energy advantages and disadvantages1

Disadvantages of solar energy

When we think of the disadvantages of this type of renewable energy, often costing much more to think about anything in particular except that aesthetically, it is not especially pretty when you decide to install it in the fields.

In addition, the level of radiation of this energy varies from one area to another, and the same occurs between one season and another, which may not be as attractive to the consumer.

When deciding to use solar power for a significant portion of the population, need large tracts of land , making it difficult for this type of energy is chosen.

In addition, another drawback is that initially requires a strong economic investment to which many consumers are unwilling to risk.

Many times you should complement this method of converting energy with others, such as for hot water and heating, require a pump to circulate the fluid.

Places where there is more radiation, are deserted places and away, (energy not used to develop agriculture and industry , etc …)

Solar energy advantages and disadvantages2

In some countries, like Germany, solar energy playing a major role; the late 80s and early 90s were launched several plans for the construction of solar power plants and solar roofs. Furthermore, the German government has encouraged the implementation of this type of energy and aid subvencionas.

In Rajasthan (India), have been built solar cookers, with the capacity to feed 1,000 people a day. The world’s largest solar cooker can serve 33,800 meals a day.

Cyprus is the country with the most amount of solar energy produced per capita , and more than 90% of its buildings contain solar thermal collectors.

Greece is capable of supplying one in four inhabitants through solar power , and solar power plants account for over 20% of all Europeans.

In Israel, a law introduced 20 years ago, requires that buildings are equipped with solar collectors, which means that 85% of homes have solar power.

China is the country with the largest area of solar collectors installed, totaling 40% of all the sensors in the world would be in China.

Then we leave you a video explaining about solar energy for you to enjoy interactive manner on this type of renewable energy.
