Facts about solar energy

There is so much energy coming from the sun, that we only need a fraction of it to power the Earth.

The Earth receives more than enough energy from the sun in an hour to supply the world's energy requirement for the whole year.

Unfortunately, only a tiny portion of it is harnessed and the world still relies on power plants that burn fossil fuels.

The good thing, though, is that there is a constant increase in demand for solar energy. Over the years of continuous development, solar panels are much cheaper today than they were just 10 years ago.
 

Solar power in peak hours

During peak hours, the maximum solar power density that the sun can give is about 1 kW per square meter. In other words, one square meter of a solar panel can produce as much as a 100 GWh of electricity in a year. That's enough to power 50,000 houses, from one meter of solar panel.

A solar power plant in the desert

If a solar power plant is built on just one percent of the Sahara desert, it will satisfy the world's energy requirement. the efficiency of solar panels depends on several factors such as pollution, clouds, temperature, and atmospheric humidity.
 

Solar power plants

Solar power plants are very similar to other conventional power plants, with one significant difference. The majority of power plants draw their power from coal and gas and other fossil fuels, they produce greenhouse gasses that contribute to global warming. Solar power plants or solar power thermal power plants utilize the power of the sun's rays to generate electricity.
