The energy output of a 1 KW solar energy unit is roughly equivalent to the burning of 170 pounds of coal and 300 pounds of carbon dioxide being released into the atmosphere.
Third world countries with an abundance of sunlight and a population currently without electricity, represents the fastest growing market for solar energy, with the largest domestic market being the utilities sector.
It takes about 8 minutes for the Sun Ray to reach the Earth. Th Sun is 93,000,000 miles away therefore travelling at the speed of 186,282 MILES per second.
Oil companies predict that 50% of the world's energy will come from renewable sources by 2040.
Albert Einstein won the Nobel Prize in the year 1921 for his experiments with solar energy and photovoltaics.
If we covered a small fraction of the Sahara desert with Solar panels we could power the entire world.
The sun is also the main source of non-renewable fossil fuels (coal, gas and petroleum), which began life as plants or animals whose energy came from the sun millions of years ago.
Enough Sunlight falls on the Earth every minute to power the World for a Year.
Solar cells have about a 15%-20% efficiency rate in converting that energy. But still Solar Power technology is efficient.
In one hour more sunlight falls on the earth than what is used by the entire population in one year.
One of the most common uses of the solar energy is as a power source, since early 1970’s, people have been putting up solar collectors on their roof tops
The human use of solar energy is not new. The history of solar energy is rich. Building methods have for many centuries taken account of the sun’s movements in optimizing its warmth and light.
All TV and communications satellites are powered by solar energy using photovoltaic Panels.
A 1-kilowatt home solar system consists of about 10-12 solar panels and requires about 100 square feet of installation area.
Solar energy can also be used to heat swimming pools, power cars, for attic fans, calculators and other small appliances. It produces lighting for indoors or outdoors.
When silicon is Taken from just one ton of Sand to make Solar Cells, it will produce as much electricity as 500,000 Tons of burning Coal
That about 30% of our total consumption energy is used to heat water.
