the maximum power density that the sun can give is about 1kW per square meter. In other words, one square meter of solar panel can create as much as 100 GWh (gigawatt hours) of electricity in one year. That is enough to power 50,000 houses.
If a solar power plant is create on 1% of the total land region of the Sahara desert, it will satisfy the world’s energy requirement.
The efficiency of solar panels depends on many elements such as pollution, clouds, temperature and atmospheric humidity.
Solar power plants are quite similar to other conventional power plants – with one substantial distinction: The majority of power plants draw their power from fossil fuels like oil, coal and gas.
