Solar Energy

At Air Shop Australia we believe in sustainable renewable energy sources. We acknowledge the fact that as of yet technology hasn’t perfected matters however it is very evident that enormous advances have been made in a short period of time. We encourage people to use these resources at home and set the standard rather than simply rely on Government to do all the work. Every little bit helps. It is to the earths advantage one lump of coal by one lump of coal. Solar seems the first choice.

What is solar energy?

Solar energy is that produced by the Sun’s light – photovoltaic energy – and its warmth – solar thermal – for the generation of electricity or the production of heat. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors.

Photovoltaic solar cells convert sunlight directly into electricity by the so-called photovoltaic effect, by which certain materials are able to absorb photons (light particles) and liberate electrons, generating an electric current. On the other hand, solar thermal collectors use panels or mirrors to absorb and concentrate the Sun’s heat, transferring it to a fluid and conducting it through pipes to use it in buildings and installations, and also for electricity production (solar thermoelectric).

What are the benefits of solar energy?

Solar energy offers many benefits that make it one of the most promising energy forms. Renewable, non-polluting and available planet-wide, it contributes to sustainable development and job creationwhere it is installed.

Likewise, the simplicity of this technology makes it ideal for using in rural or difficultly accessed areas isolated from the network. An example is the rural region of Cajamarca in Peru, where ACCIONA has developed several projects to facilitate electrical self-sufficiency for inhabitants. Solar energy is also useful for generating electricity on a large scale and injecting it into the network, especially in regions where the meteorology provides for lots of hours of sun per year.

Solar capture modules are relatively easy to maintain, which, along with the continuing, sharp reduction in cost of photovoltaic cells, explains the present favorable outlook for solar technology. Solar plants also do not emit polluting gases and are silent.

Another advantage of energy borne from the Sun is its ability to generate local wealth, by lessening energy dependence on abroad. While it is certain that solar energy – like wind – is intermittent and directly depends on the weather and day-night cycles, rapid advances in electricity storage technologies are reducing this dependency and will lead to the increasing share of solar in the energy system.

 

SUMMARY OF THE BENEFITS OF SOLAR ENERGY

  • Renewable
  • Inexhaustible
  • Non-polluting
  • Avoids global warming
  • Reduces use of fossil fuels
  • Reduces energy imports
  • Generates local wealth and jobs
  • Contributes to sustainable development
  • It is modular and very versatile, adaptable to different situations
  • Can be applied alike for large-scale electricity generation and on a small scale in areas isolated from the network

How is solar energy obtained?

The sun provides energy in two different ways:

  • It provides heat tapped by mirrors that focus sunlight on a receiver that contains a fluid which reaches temperatures up to 1,000 ° C. The heat transforms the fluid in steam which moves a turbine and finally produces electricity.
  • It provides light that is converted into electricity through photovoltaic solar panels. Photovoltaic panels are formed by groups of cells or solar cells that convert light (photons) into electrical energy (electrons).
