Renewable Energy in our World
Solar Energy
What's Solar Energy?
Solar energy, as part of renewable energy, means the capacity to transform sun’s properties, like light and heat to be used in the human daily life needs.
The solar energy can be transformed using three different technologies:
​
Furnace systems
​
​
They use the solar heat property to produce electricity. It has mirrors that concentrate large amount of solar energy in a small area, reaching temperatures of up 2000 °C. The heat could be used to make steam and that steam would be use in a power plant to produce electricity.
Furnace systems
Heating System
They take the solar energy with a device called flat-plate collector, this collector is a black metal covered with glass, usually located at the building roofs. The collector absorbs the solar energy and heat the air or the water that flows through pipelines behind it.
The air or water moves around the building to heat it, for sanitation uses or can storage in a tank for later use.

Solar Cells:
​
They use the light of the sun instead of the heat to produce electricity. These cells are called Photovoltaic cells or PV because they can turn sunlight into electricity. “Photovoltaic” comes from the word “photons” that are particles that are part of the sunlight and the word “volts” that is a measurement of electricity.
​
A solar cell produces a small quantity of electricity, a solar panel, that is a group of solar cells is able to produce the amount of energy needed for a house or a building.

How does Solar Panel Work?
Solar Energy is a cheaper, cleaner, and accessible solution for development countries because most of them are in sunny areas. It is also an excellent solution for remote places where National Grid has not reached. The solar energy will be continuously improving and making more feasible, the total substitution of fossil energy for clean and renewable energy in the near future we will depend more on the community choices.
