There is a lot of power packed in our sun that all living things on earth depend upon. Humans have been able to capture some of the sun’s energy that falls to earth and convert it into usable power for a variety of practical uses like for cooking, heating, and to power everyday appliances.
Solar energy is that produce 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).
Solar energy is a major renewable energy source with the potential to meet many of the challenges facing the world. There are many reasons to promote its share in the energy market. This power source is increasing in popularity because it is versatile with many benefits to people and the environment.
Solar energy offers many benefits that make it one of the most promising energy forms and proven it as the one of the most important source of energy. Renewable, non-polluting and available planet-wide, it contributes to sustainable development and job creation where it is installed.
- 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
