Which are the benefits of Solar energy?



“Use of Solar power is close to a solution”. This used to be the headline in the New York Times on four April 1931. It became out to be a premonition, since, 80 years later and electrical energy is being furnished to millions of human beings in the world from renewable energies such as solar. Humanity has now declared its readiness to accelerate the transition to a low-carbon economy, aware of the finite nature of fossil fuels and their prejudicial consequences on the environment as the principal motive of global warming.

As the poet, Pablo Neruda kissed at the l hole: “I am a man who comes in light, in the light of this kind of light, I will die with a glow.” Solar energy, on the different hand, will by no means die of shining, considering the Sun nevertheless has 6.5 billion years of lifestyles according to NASA. Indeed, as an alternative much less time, solar technology in some international locations has advanced to compete with traditional sources of electrical energy generation. In simply a few decades’ time, it will turn out to be a predominant phase of a sustainable energy device for the world.

Additionally, the conditions for the development of solar power could not be extra perfect: the Sun bathes the Earth hourly with adequate light and warmth to fulfill global wishes for a whole year; in other words, photo volar energy voltaic radiation can satisfy our energy wants 4,000 instances over.

As a publication, renewable energy information estimates that the surface of the ground is the solar radiation of 120,000 truths, which is, “represents more than 20,000 examples more power than the needs of the planet. “. Backing this argument further, the Union of Concerned Scientists says that as little as 18 days of photo voSolar energetic irradiation on Earth incorporates as a whole lot stronger as all the world’s coal, oil and herbal fuel reserves put together.

The NYT article put ahead of the suggestion that Humanity “will no longer have to fear the exhaustion of coal reserves foreseen within the next few hundred years if Dr. Lange’s theory is right”. Well, the phrases of German solar strength scientist, Dr. Bruno Lange, lower back in 1931, have been tested right.


What is photo volSolar energetic energy?

Solar power is produced by way of the Sun’s light – photovoltaic energy – and its heat – solar thermal – for the era of electricity or the production of heat. Inexhaustible and renewable, when you consider that it comes from the Sun, polar energy photovoltaic strength has harnessed the use of panels and mirrors.

Photovoltaic solar cells convert daylight directly into electricity through the so-called photovoltaic effect, with the aid of which sure substances are able to absorb photons (light particles) and liberate electrons, generating an electric current. On the other hand, the solar thermal components handle the heat or heat of the sun and handle the use of pipes in the buildings and installations and listen to the solar energy production (solar modification). Are there


What are the benefits of photovoltaic energy?

Solar electricity provides many advantages that make it one of the most promising power forms. Renewable, non-polluting, and handy planet-wide, it contributes to sustainable improvement and job creation right here it is installed.

Likewise, the simplicity of this science makes it perfect for use in rural or difficultly accessed areas isolated from the network. An example is a rural place of Cajamarca in Peru, the place ACCIONA has developed countless initiatives to facilitate electrical self-sufficiency for inhabitants. Solar power is also useful for producing electricity on a giant scale and injecting it into the network, in particular in regions where the meteorology affords for plenty of hours of solar per year.

Solar capture modules are distinctly convenient to maintain, which, along with the continuing, sharp discount in the cost of photovoltaic cells, explains the present favorable outlook for solar technology. Solar flowers additionally do no longer emit polluting gases and are silent.

Another gain of power borne from the Sun is its capability to generate local wealth, via lessening power dependence on abroad. While it is positive that photovoltaic electricity – like the wind – is intermittent and immediately relies upon on the weather and day-night cycles, rapid advances in electricity storage applied sciences are lowering this dependency and will lead to the growing share of photovoltaic in the electricity system.



  • Renewable
  • Inexhaustible
  • Non-polluting
  • Avoids international warming
  • Reduces the use of fossil fuels
  • Reduces energy imports
  • Generates neighborhood wealth and jobs
  • Contributes to sustainable development
  • It is modular and very versatile, adaptable to exceptional situations
  • Can be applied alike for large-scale electrical energy technology and on a small scale in areas remoted from the network


How is solar electricity obtained?

The solar affords energy in two distinctive ways:

  • It gives warmness tapped by means of mirrors that focus daylight on a receiver that contains a fluid which reaches temperatures up to 1,000 ° C. The warmth transforms the fluid in steam which moves a turbine and eventually produces electricity.
  • It affords light that is converted into electrical energy via photovoltaic panels. Photovoltaic panels are fashioned by means of organizations of cells or solar cells that convert light (photons) into electrical strength (electrons).
